The history of bitumen emulsions

Road construction industry

Bitumen emulsion were first tried as a road construction material in the beginning of the 20th century. Originally, the use of emulsion was limited due to low experience and knowledge in the area of emulsion formation, mixing and the technology of emulsion production and application. With time, the use of emulsion grew steadily from the 1920s to 1950s.

It was in the mid 1950s when the rapid increase of traffic load made the emulsions inadequate for the task. The interest in emulsions fell, however, bitumen emulsion continued to be used for some purposes.

At that period, hot asphalt mix was mostly prepared with bitumen binder. In road construction emulsion were used mostly for ground reinforcement or on secondary roads.

A new hope for the emulsion came in the beginning of the 1970s, when the energy crisis hit Western Europe and the US. Import of oil became a serious problem, especially so for the US.

At this time the manufacturers of road construction materials remembered about bitumen emulsions, which, as before, required no petroleum based solvents or additional heating for the mineral material. The advantages of bitumen emulsion in comparison with thinned bitumen in terms of the ecology were also obvious.

This caused significant extension of the use of the emulsions. Emulsion preparation and application methods saw rapid development, quality requirements became higher, test methods were developed. Emulsion production systems keep improving all the time. One of the latest and most efficient solutions is the UVB-1 type unit made by GlobeCore. Beside other advantages of the emulsion, (economic, environmental and performance), it became possible to use the emulsion almost all year long from spring to autumn in temperature above +5 ºС.

To efficiently used bitumen emulsion and emulsion based materials, it is important to know how the emulsion interacts with materials of a different origin, how it behaves in different conditions and then formulate the composition of the emulsion with the consideration of all factors.

Application of bitumen emulsions increases performance of roads, their durability and offers an efficient and inexpensive road maintenance solution.

Road top with anionic emulsions

Road construction industry

Each year more construction materials are used for construction of roads, mostly asphalt concrete based on bitumen binder.

Traditional production process for road top with hot materials has been used in road construction since the middle of the previous century; it takes a lot of energy and is not very environmentally friendly. Therefore the use of anionic bitumen emulsions is considered by the specialists as very promising. It allows to transfer from hot to cold technology of road construction and increase quality and durability of roads.

GlobeCore manufactures the UVB-1 type bitumen emulsion production units. To make the process less expensive, byproducts of the chemical industry can be used as surfactant emulsifiers.

Analysis of the existing technologies of anionic bitumen emulsion production shows that the best method is combined emulsification, which allows production of a finely dispersed product.

The traditional bitumen emulsification method uses prepared soap. In the combined method, half of the fatty acids are mixed in bitumen, and the other half is saponified in water solution. Then both phases are mixed in KLM type disperser for final emulsification of bitumen.

Bitumen emulsion reduces dust from dirt roads

Road construction industry

Pit roads, crossings and driveways are by nature very dusty. In the general case, the amount of dust kicked up into the air depends on the surface of the road, its condition, weight and speed of vehicle movement. A large amount of dust in the air causes accelerated engine wear, limits visibility and causes serious lung conditions in affected people.

The problem is made worse by the wind. If wind speed is 3 – 5 meters per second, the amount of dust falling outside the road may be 1/3 or 1/2 of the toral dust amount. In standard units this is 0.15-0.9 kg/m3. The factors listed above cause visibility problems, forcing traffic to move slowly.

The negative consequences can be alleviated by using modern dust control methods and road surfaces.

The existing methods can be roughly divided into three groups. The first group includes mechanical techniques: washing, blowing, vacuuming. Special equipment may be used: graders, brushes etc. The second group includes techniques of mixing the road top material with special binding and adhesive materials. This results in dust-free agglomerates. The third method is to treat the surface with adhesive materials and chemicals.

The most commonly used method is also the least efficient. The road is rinsed with water and dusted with special brushes. However, the source of dust remains. Besides, at the temperatures above 25 ºС and relative humidity below 50% the water evaporates and the dust returns in half an hour.

The International Road Association suggests the following. First, the surface of the road is prepared, then moisturized and profiled. Then bitumen emulsion is applied to the road. The emulsion may be made with GlobeCore’s UVB-1 units with production capacity range from 1 to 8 cubic meters per hour. The UVB-1 allows dust control measures to be taken almost year round, from early spring to late autumn (as long as the temperature is above +5 ºС). After introducing the bitumen emulsion, the ground is compacted.

A certain amount of water may be used to dampen the ground and thin the emulsion. This will allow uniform distribution of the emulsion on the surface and easier mixing with the top layer of the road.

Application of bitumen emulsion for dust control on dirt roads has the following advantages:

  • process economy. The amount of bitumen emulsion used is relatively small;
  • materials treated with bitumen emulsion are more durable;
  • it is possible to work with wet materials.

There are also limitations:

  • bitumen emulsion cannot be applied to clay materials or materials oversaturated with water;
  • flexibility of the reinforced material is low.

For long term dust prevention, the top layer of the road should be treated to the depth of 5 – 6 cm.

Bitumen emulsion for road construction

Road construction industry

Road top degrades during operation sue to two groups of factors: mechanical and climatic. Mechanical damage is caused by fatigue of the road top due to transportation load, made worse by uneven surface. This happens, for instance, when heavy trucks (30 tons and above) pass along the road in summer in temperatures in excess of 30ºС.

Climatic factors influence the asphalt due to poor quality of the binder (bitumen) and/or due to sharp changes of bitumen properties during production of bitumen-mineral mix.

The former case is mostly cause by inadequacy of bitumen or polymer-modified bitumen properties. For instance, traction on glass can somewhat characterize adhesion properties of bitumen. It can be determined but not regulated: the important thing is to determine bitumen viscosity and the content of paraffin and cohesion of bitumen-polymer material.

Sharp changes in bitumen characteristics during production of road top is caused by oxidation of bitumen in traditional hot process, which increases the rate of its aging.

Aging of bitumen in a road top under the influence of oxygen, elevated temperature, moisture and catalytic minerals occurs in four stages: strengthening of the structure, stabilization, beginning of destructive processes and destruction. An accelerated transition from the first two to the last two due to heating of bitumen during mixing with mineral material occurs due to two key factors.

First, bitumen heating causes local or general overheats. Regardless of mix composition and bitumen quality, the aging processes accelerate sharply above 160 °С.

Second, the rate of aging depends on the way bitumen was heated: in volume or in film covering mineral particles. Film bitumen in asphalt-concrete ages faster  with all other conditions equal. Today, bitumen plants use collection tanks to store ready asphalt mix from one shift to several days at high temperature. The rate of aging of the film layer during storage and transportation at elevated temperature significantly accelerates aging during operation. In such conditions aging is so quick that bitumen increases consistency by the hour. In the result, the mix contains bitumen with lower penetration and viscosity and higher softening point than originally intended. This is one of the most important causes for reduction of road top service duration.

Reduction of influence on asphalt concrete of the above mechanical and climatic factors can be achieved by changing the regulations defining the consist and quality of the material and the binder. Reduction of bitumen aging rate in operation conditions can be achieved by changing of bitumen-mineral mix production technology.

There are two alternative approaches to reduction of bitumen viscosity to the point where it can be efficiently mixed with mineral filling material: using solvents and the use of bitumen emulsions. The former method increase the cost of bitumen products and causes significant damage to the environment by releasing vapors of organic solvents.

The emulsion base technology of bitumen based road top has become wide spread in recent decades. Beside reducing the bitumen’s aging rate, using emulsions has other advantages (less energy consumption, ability to lay the road top on wet surface etc) over the traditional hot technology.

The amount of asphalt mix based on bitumen emulsion increases. In 2006 over 30% of all binding materials in France were emulsified.

It is necessary that the consist and method of emulsion preparation ensure the required viscosity and stability in transportation and storage, with relatively low cost of raw material. The component which influences the above parameters the most is the emulsifier.

The components used for the production of bitumen emulsion and the production process is mainly defined by the process equipment.

Among the currently available plants for production of cationic or anionic emulsions, the UVB-1 plant by GlobeCore is one of the most efficient. By choosing the model of the required production capacity, the client can optimize the process of bitumen emulsion production at the facility with guaranteed production of the required quantity and quality of the product.

The Functions and Methods of Bitumen Emulsions Production: The Aqueous Phase Block

Solutions

Different types of bituminous emulsions are used in many different applications in the modern construction industries.  The many different uses of bituminous emulsions include the following examples:

  • For priming of old pavement before applying a new layer of asphalt or concrete;
  • To prepare cold asphalt mixtures;
  • For the surface treatment of road surfaces;
  • For applying thin protective coating layers;
  • For patching roads;
  • For waterproofing of buildings and structures;
  • For the installation and repair of soft roofs.

The main advantages of bitumen emulsions, in comparison with conventional bitumen (or resin), is their ability to work in high humidityand low ambient temperatures while using less bitumen product to complete the job.

Another advantage of bituminous emulsions is their ability to work in adverse weather conditions.  The use of hot bituminous mixtures, even with the addition of surface-active additives, do not meet the same high quality standards as bituminous emulsions for performing road work.  Due to such a wide range of benefits, bituminous emulsions are increasing in demand and popularity in the road and building construction industries.

Based on the demands for bitumen emulsion products, there is also a need for plants and equipment that can efficiently produce the highly popular emulsion products.  The GlobeCore UVB-1 unit is a semi-automatic machine that produces bituminous emulsions for the construction industries. The UVB-1 consists of several individual parts that are mounted on the same frame.  There is a block for  the preparation of the emulsion, a block for the aqueous phase of the process, and an operator control unit.

Production of bituminous emulsions normally has two stages, a preparation of the emulsion stage and an aqueous phase.

The aqueous phase creates an aqueous solution of an emulsifier.  It also creates an emulsifier agent for the transition into the ionic form (acidic reagents for cationic emulsions and alkaline – for anionic) and the other necessary components to improve the properties of the final emulsion product.

The parts of the UVB-1, that perform the aqueous phase of the process, are wrapped with a piping system with indicators for visual control of fluid flow.  It also has built-in control valves and instrumentation valves.  The aqueous phase is performed in the tanks with agitators according to a predetermined emulsion recipe.  The unit’s controls set the volume, the temperature, the pH level, and amount of the individual components of the emulsion mixture.

The fully prepared aqueous phase mixture and hot bitumen are then placed in a colloid mill for mixing.  If necessary, the colloid mill can liquefy the bitumen mixture with an injection of a special bitumen diluent in the piping system.  Preparing the components of the aqueous phase and injecting the diluent is carried out automatically with the aid of pumps and corresponding conduits for the continuous, uninterrupted production of the bitumen emulsion products.

The necessary water supply is set and introduced to the blending via vertical multistage pumps.  Direct control flow is regulated by rotameters with different ranges up to 10m3/h for water, up to 4m3/h for blending, and up to 0.25m3/hour for a breaker.

A large number of world renowned road, civil, and industrial construction technologies use complex types of bitumen emulsions according to individual recipes.  Recently, the domestic and international markets are using more and more modern systems for producing high-quality bituminous mixtures and emulsions.

Based on recent inspections and testing, it appears that the new equipment models and formulas have been able to achieve an even greater positive effect in the uses and functions of bitumen emulsion products.  GlobeCore has been an industry leader in developing and producing such bitumen emulsion equipment for the road construction and building construction industries.

Bitumen Emulsions – What’s new? The GlobeCore BGU-6 Bitumen Emulsion Unit in the Making!

Solutions

The market for road building materials is growing rapidly.  Economists say; “in globalization lies the stimulant of development.”  What worked for my neighbor should also work for me.  And if the neighbor is a rich and developed country, its technology may be better and more profitable.  So how can I do the same, or even better?

Most buyers can easily access the global market for goods and services.  This includes industrial buyers as well as domestic consumers.

The Company; “IndustrialServis” studies the market for industrial equipment and has successfully worked in it for many years.  Partnerships with client companies in different fields of activity in over 70 countries significantly affect the ongoing process of its product selection.

Equipment for the road construction industry, that makes bitumen emulsions, is also constantly undergoing developments and improvements.  The GlobeCore UVB Bitumen Emulsion Model has been designed to produce both anionic and cationic bituminous emulsions.

The new UVB-6P model, that produces bitumen emulsion in a stream, is a newly modified unit.  It performs the same functions as its predecessor and is used for the production of asphalt with certain special industrial properties.  The GlobeCore UVB-6P bitumen emulsion unit can be used both indoors and outdoors under a covering.  The ambient operating temperature range is between +5°C and +40°C/41°F and 104°F.

UVB-6P works on the same principle as the previous model where water is supplied through pipe that lead to the tank with heated bitumen.   The dosing pumps supply a specified amount of acid, emulsifiers and other special additives.  All the ingredients are then mixed by the base pump and then fed into the container for mixing with water and bitumen.

The UVB-6P was developed in response to increasing demand and interest in this kind of of modern road building equipment.  In contrast to the cyclical patterns of operation, with the UVB-6P, there is a continuous supply ingredients for mixing after pushing the start button. the commences the UVB-6P’s semi-automatic process.

The basic elements of the UVB-6P are mounted on a frame.  These elements include the bitumen pump, the water pump, various mixers, tanks, pipe network, and control valves.

In addition, the “Wetlands” version of the UVB -6P is equipped with a heating system, monitor, temperature sensor, and a pressure sensor.  The control panel is located in a cabinet that consists of a sealed metal case.  The control panel allows the operator to completely monitor and control  all the processes of the unit.

The GlobeCore UVB-6P is a new class of equipment that was born out of an increased demand for non-standard products and technologies that save time, labor costs and money.  Bitumen emulsions made with the GlobeCore UVB system reduce processing time and operating costs.

Methods of Preparing Bitumen Emulsion: The Aqueous Phase Block

Solutions

Different types of bitumen emulsions are applied in different industrial processes. Some of the processes include:

  • The priming of the old pavement before applying asphalt or concrete;
  • To prepare cold asphalt mixes;
  • To “surface treat” roadways;
  • To provide thin protective coatings;
  • For patching roads;
  • For waterproofing building foundations and structures; and
  • For installing and repairing soft roofs.

The main advantages of bitumen emulsions, in comparison with conventional bitumen (or resin), is its ability to be used during high humidity conditions, low ambient temperature conditions and that fact that it requires less bitumen consumption to complete the job.

Due to the fact that bitumen emulsion has a significantly lower viscosity level, as compared with ordinary operating resin, roadwork heating of emulsions and mixtures can be eliminated.

Bitumen emulsion products allow for work to continue even during adverse weather conditions.

On the other hand, the use of hot bitumen mixtures, even with the addition of surface-active additives, do not provide the required quality of work as with bitumen emulsion products.

Due to the wide range of benefits, bitumen emulsion products are increasingly being used in the road construction and building construction industries.   The greater demand for bitumen emulsion products has in turn created a demand for equipment that can produce quality bitumen emulsion products.  There is now a great need for the acquisition of systems that are capable of creating the right substance by mixing asphalt with water and various additives to form the bitumen emulsion products.

The GlobeCore UVB-1 model is a modern machine that can produce bitumen emulsions for the road and building construction industries.  It is a semi-automatic machine consisting of several independent parts mounted on the same frame.  It includes an emulsifier and an aqueous phase block with complete device management controls.

Production of bitumen emulsions is performed in two stages.  An aqueous preparation phase and an emulsion preparation phase.  The aqueous phase uses an emulsified aqueous solution to create an ionic emulsifier agent (acidic reagents for cationic emulsions and alkaline-for anionic) or other necessary components that improve the emulsion properties.  The Aqueous phase block is equipped with a piping system with indicators for visual control of fluid flow, valves, measuring instruments, and shut off valves.

The aqueous phase prepares the mixture in tanks in accordance with the desired emulsion recipe.  Adjustable settings include volume, temperature, pH level and the amount of the different ingredients.  The mixture, that has been fully prepared in the aqueous phase, and hot bitumen are put into a colloid mill for mixing.  If necessary, bitumen can be liquified and distributed by injecting a dilatant into the bitumen pipeline.

Mixing during the aqueous phase and the diluent processes are carried out automatically with pumps that direct the mixture into corresponding piping for continuous production of bitumen emulsions.

Vertical multistage pumps are installed to supply water to the blend.  Dilatant feeding is performed by the use of a geared pump.  The moving/rotating components are regulated by rotameters with different ranges up to 10 m3/hr for water, up to 4m3/hr for blending and up to 0.25 m3/hr for diluent.

Many world-renowned road, civil, and industrial construction technologies use complex types of bitumen emulsions according to specific individual recipes.  Based on world wide demand, there are now brand-new models and formulas to achieve an even greater effect in the use of bitumen emulsions.  The best company to meet your road construction equipment needs is GlobeCore and its line of bitumen emulsion equipment.

GlobeCore Model VBU-6P

Road construction industry, , ,

One of the essential pieces of equipment that is being used more and more in modern industrial and developing nations is the “Bitumen Emulsion” production plant.

The use of bitumen emulsion has several advantages over simple bitumen or tar products in most or all applications.  Most important is that bitumen emulsion does not require constant heating thereby increasing the efficiency of industrial operations and lowering operating costs.

Bitumen emulsion has a more complex structure than tar and simple bitumen, and due to its lower costs, it has become more and more popular in the road construction industry.  Bitumen emulsion production equipment is now indispensable to the road construction and related industries.

The bitumen emulsion equipment by produced GlobeCore is the most up to date and efficient bitumen emulsion equipment in the industry today.  GlobeCore engineers remain leaders in their field and are always seeking to improve and upgrade the quality and efficiency of the GlobeCore equipment line.  That is why new GlobeCore equipment will never be outdated versions of yesterday’s models.

The GlobeCore universal bitumen model makes both anionic and cationic bitumen emulsions. Often, this kind of equipment is used by companies that produce asphalt mixes.  Bitumen emulsion of this type is most often used for the priming of old pavement before applying a new layer of asphalt.  It is also used in the preparation of cold asphalt mixes, for the surface treatment of existing road surfaces, for making thin protective coatings, and for patching roads.

One of the latest bituminous equipment developments by GlobeCore is the VBU-6P model designed for the production of bitumen emulsions.  The name of the new model reveals the main differences from the previous models with a production rate of 6.5m3/hr and the ability to work continuously without interruption.

The Globecore VBU6-P consists of two main parts, the  bitumen part and the base part.  The Bitumen part stands vertical and has a pump made ​​in Italy.  The base portion is where the emulsifier, acid and bio chlorine additive are mixed and then fed into the polypropylene container. Each component of the mixture pass through dosing pumps.  The pumps automatically measure the required amount of each component of the mixture.

The  VBU-6P system works by feeding bitumen from a reservoir into the bitumen part through a feed pipe and passes the bitumen through to a set of heating rings.   Water is supplied to the mixing cylinders and the dosing pumps then pump the emulsifier acid according to the product recipe.

The container, in which the mixing occurs, is equipped with volume level sensors.  When the amount of mixed fluid reaches the high-level indicators, the sensor signals the completion of the preparatory phase.  Next, the water valve opens and the unit starts to run the aqueous phase of the process.  The VBU-6P will continue to run unless the water supply is cut off, or until the operator turns it off

The VBU-6P is  fully automated.  The only manual control is for  the adjustment of the ratio of bitumen to water (a mix of 70% bitumen and 30% water will be made at the rate of 6m3 while a mix of 50% to 50% will be made at a rate of 9m3).

It is also possible to manually adjust the amount of emulsifier that needs to be fed into the process. For fast decaying emulsions, emulsifiers of 0.25% are used.  For slow decaying emulsions – 2% are used.  Acid is added automatically through the acid probe found on the dosing pump.  It is responsible for regulating the engine speed and the feed rate and volume of the acid.

The GlobeCore VBU-6P bitumen emulsion processing unit is a high quality product that leads the industry.  It is both durable and highly resistant to delamination and corrosion.  The VBU-6P’s automated process of mixing the various components combined with a versatile design make the GlobeCore VBU-6P unit the most advanced bitumen emulsion processing unit in the industry today.

Tar Paver RBE

Road construction industry, , , , , ,

The “Tar Paver” is a machine designed to uniformly “pressure pour” hot organic binding materials that are based in tar for the construction of roads and for making road repairs.

Tar is known as a fragile, black friable pulp obtained from refinery waste that can be used as fuel, insulating material for electric cables, and for road construction/repairs.  Of the total weight of the distilled oil, anywhere from 10 to 45% of the oil can become tar.

Tar is considered to be most effective for use in road construction, roofing and construction bitumen due to its astringent properties and its overall chemical composition that includes paraffinic, naphthenic and aromatic hydrocarbons, asphaltenes, etc.

Tar Pavers are used in many different sectors of construction, but particularly they are used in road construction.  The Tar Paver is structured with a tank mounted on a truck or on the chassis for possible transport to and around a construction site.

The Tar Paver principally operates with a sprayer mechanism.  The Tar Paver is capable of applying large volumes because of the built-in junction rod.

The Tar Paver is used for spraying bitumen emulsion. This Tar Paver however, is not suitable for bitumen as this it is not designed to maintain the high temperature needed to keep the binder in the liquid state which needs to be between 180°C to 190°C/356°F to 374°F.

Demand for high-quality road construction products has stimulated the emergence of different Tar Paver models.  If their tanks are fixed in the back of a truck, then the bar is set on a hydraulic pantograph and remains on the tank during unloading.  If the paver is installed on a truck chassis, it is called an asphalt distributor.

The unit’s Storage Tanks have different capacities to enable them to adapt to the size and weight of the vehicle selected for transporting them.  GlobeCore’s Tar Paver RBE – bitumen emulsion sprayer has the flexibility to be fitted with tanks that have a fluid capacity of between 500 to 10,000 Liters.  The internal design of the tanks provides for heating and/or for maintaining the desired temperature of the bitumen emulsion with burners that use liquid petroleum gas or diesel for fuel.

The GlobeCore Tar Paver RBE model is equipped with  that are connected to and are proportionate to the pole of the internal combustion engines driving them.  The spraying of bitumen emulsion is performed ​​with rods classified according to their characteristics and functions.  They range from a simple rod with a system opening known as a collapsible type, to a more complex system of rods with the opening that is a sliding type with a hydraulic drive controlled from inside the cabin of the vehicle.  When the vehicle is in transit, the rod is folded and fixed with pins. The top rod is lifted by special hydraulic motors and with a hydraulic cylinder that works in a manual mode.  To control the temperature of bitumen emulsion inside the Tar Paver, the RBE models feature a temperature sensor that is connected to a gas heating system.

The rail pressure for spraying is increased to the desired pressure by a “Frokarola” bitumen pump equipped with a German engine.  The bitumen pump is rotated by a hydraulic motor which in turn starts the hydraulic pump.

Emulsion outflow depends on the performance of the bitumen pump. The volume of sprayed material by the Tar Paver RBE is 0.3 liters/m^2 at a speed of 3 km/hr.

GlobeCore Tar Paver RBE models are much more convenient to use.  This is due in part to the control capabilities of the pump, lifts and other core functions.  The control capabilities can be accessed from an external console that can be operated from the external remote control or installed in the cabin next to the driver.  An alternative design places a stationary system of controls in the cabin of the truck.  In any case, each unit is mounted to suit the individual preferences and requirements of the client.

Optional additions to the Paver Tar RBE are as follows:

  1. Water tanks made of hot galvanized steel with transfer pump and hydraulic emulsion recirculation system;
  2. “Ecological” cleaning system of dirty detergent (diesel fuel, etc.), thus avoiding the need to reset the contaminated liquid with consequent damage and environmental pollution;
  3. tanks for diesel fuel to refuel fixed installations;
  4. many other solutions to facilitate the work on site and accelerate and increase the profitability of your company.

Model UVB-10PK

Road construction industry, , , , ,

Bitumen emulsions are very popular among consumers of building materials. Ordinary and industrial consumers, construction companies, and road-building companies pay particular attention to them.  Something that brings tangible benefits cannot remain unnoticed.

Bitumen emulsion is made by mixing bitumen and water with special equipment while adding emulsifiers (usually chemical class products amines) and acids. There are both benefits and limitations when using bitumen.  It is also important that the water used in the mixture does not have excessive mineral salt levels.

Bitumen emulsions are classified according to three criteria: (1) the sign (+positive or -negative) of the electric charge of the pellets; (2) the decay rate; and (3) the weight and content of the bitumen base binder.

Bitumen emulsions are further divided by their concentration levels.  Depending on the intended application, bitumen emulsions can have the following levels of concentration: 50%; 55%; 60%; 65% and 69%.

The decay rates of emulsion are categorized as being rapid, medium, slow or ultra stable. According to the sign of the electrical charge of emulsion granules (+positive or -negative), they are either anionic or cationic.  The latter one is more widely used due to a stronger adhesion level to the stone materials of acid rock.  Having greater adhesion characteristics is a great advantage in the construction industries

GlobeCore is one of the most successful and reliable manufacturers of bitumen equipment.  Years of experience and extensive marketing has stimulated continuous improvement of existing technologies and the developing of new and better ones making the GlobeCore equipment a worldwide industry leader.

The production process of bitumen emulsion is based on dispersion of bitumen in water.  A mechanical colloidal mill separates the bitumen into smaller particles. Due to the emulsifier’s physic-chemical energy, surface tension is enhanced at the interface between the hydrocarbon and water phases and forms a film around the particles.

The GlobeCore UVB unit is designed for processing both cationic and anionic bitumen emulsions.  The great demand for GlobeCore equipment is the result of the versatility, flexibility, and the number of many other advantages offered by the UVB unit.  This demand has also served to drive the industry to research and develop new and better technology.

The GlobeCore UVB-10FS model is similar to technologies of its kind from perspective of construction.  The letters “FS” in the model designation represents an improved set of components that provide additional security and special features that include the presence of a heat generator, container for the generator, and a removable tank.  The entire unit consists of 5 parts that can easily be placed in 20×40 cubic containers if needed to be transported.

This kind of UVB equipment is intended for use in both outdoor and indoor applications.  Typically, the UVB is a semiautomatic piece of equipment that consists of separate units connected by pipelines that mounted on the same frame.

The main functional blocks for the production of bitumen emulsions are the aqueous phase block, and the emulsifying block.  They are connected to containers holding emulsifier acids and thinners.

The main block of the UVB-10PK is a bitumen boiler.  Bitumen, before being fed into the unit, is prepared in a mini-laboratory equipped with various devices for testing the emulsion, pH levels, and chemical content.

The UVB-10PK unit has a bitumen receiving unit that has a lift for loading and unloading bitumen products. Two people, the operator and the laboratory technician, control the whole setup.

Heating occurs by means of thermal oil that is supplied from the heater through piping in each individual block.  Operational performance of the UVB-10PK is 8 m3/hr.  At this performance level, power consumption is about 96-100 kW.

The package also includes a bitumen storage section.  This section consists of a container in which there is a system for heating water and has a thermo generator.  The top bitumen storage section is equipped with a tank with either one or two receptacles for receiving the emulsion.  Both the Bitumen storage and Emulsion tanks are equipped with stirrers.

The volume of bitumen storage equals 30-32m3, water storage equals 8-10m3, the emulsion tank equals – 16m3 and the bitumen boiler equals – 10m3.

With full integration, multi-directional operation, and versatility, the UVB- 10PK has become a very popular and profitable asset.
