Roads of Ghana are Built and Repaired with GlobeCore Equipment

In April, representatives of our company visited Ghana to access the current state of a UVB-1 plant.

This equipment was sold in 2012 and has since produced 40000 m3 of bitumen emulsion. This material is in demand in Ghana, as this country is badly in need of building new and repairing the existing automobile roads.

Application of bitumen emulsions in road construction industry boosts the quality work significantly, expands work season, saves binding materials and fuel. Using emulsions also reduces hazardous emissions into atmosphere.

As a results of the trip, we state that after four years of successful operation in Ghana the UVB-1 is in good state and ready to contribute to the progress of road construction industry of Ghana.

GlоbeCоre Begins to Manufacture New Equipment for Peanut Butter Production

In the first quarter of this year, GlоbeCоre announced the start of the production of new lines for peanut butter preparation.

More than 4 million tons of peanut butter are produced in the world annually because of its high demand in the cooking and baking industries, cosmetology, confectionary and pharmaceutical industries.  The xport and consumption of this product however, differs considerably in different countries due to the peculiarities of the different production techniques used in each country.  For example, even a slight temperature deviation from the set value during the nut meat processing can lead to the loss of valuable raw materials.  Shortcomings of the preliminary preparation process can lead to the bitterness of the finished product.

Not all businesses have equipment that can meet all the production requirements needed in order to produce a high quality and a cost competitive  peanut butter.  With this in mind, GlоbeCоre has developed a new line for the production of peanut and other pourable food products.  This new equipment line includes units for raw material grinding (colloid mill), powder drying (drying cabinet), metering and blending with additional components (blending machines).  These lines are fully automated and energy efficient.  They provide for high quality peanut butter production in accordance with the original formula.

In today’s competitive food market, a colloid mill is the most effective device for grinding and preparation of dispersed systems.  It can simultaneously disperse, homogenize and grind the source material down to the size of five (5) micron particles.

The blending system operates according to the principle of hydrodynamic impact that causes a cavitation effect to achieve the desired results.  The main advantage of such equipment is the possibility to blend in one pass up to 5 liquid additives as well as the peanut powder.  The final product possesses stable taste qualities, is transportable and can be stored.

UVB-1 Bitumen Emulsion Plant was Launched in Azerbaijan

Early February, members of GlobeCore had a business trip to Baku (Azerbaijan).  The purpose of the trip was commissioning and launching of the previously supplied UVB-1 plant (capacity of 2 m3/h), designed to produce bitumen emulsions.

The project was completed on time,  in full compliance with international quality standards – which allowed the workers of Azerbaijan to start  production of bitumen emulsions.

Today bitumen emulsions are generally used for:

  • Surface treatment.  The main advantage of using bitumen emulsion is its ability to work with wet gravel;
  • Fine sealcoating.  Selecting an emulsifier allows for quick coating.  Active traffic can be resumed in 1 or 2 hours after completion of works;
  • Preparation of cold mixes for recycling directly on the site;
  • Impregnation of soil consisting of gravel and sand;
  • Seal coat (waterproofing, providing non-skid surface, anti-glare surface, reducing deterioration and cracks);
  • Surface tack coat treatment (for best bond strength treatment of pavements);
  • Macadam pavement (gravel impregnated with bitumen).

GlobeCore produces all types of bitumen emulsions to meet the challenges of road construction, as well as modified emulsions for roofing and waterproofing works.

Specifics of bitumen emulsion modification

Water-bitumen emulsion is a highly dispersed dark brown material made by atomization of bitumen in water solution of an emulsifier.

Such methods of bitumen thinning as organic solutions and hot mastics are prohibited in several European countries due to environmental and health hazards. A better and more efficient method is emulsification. The process is becoming more popular, replacing the other methods and taking its well deserved place in the market.

Although emulsion itself is an advanced material for road construction and waterproofing of buildings, it is often modified with synthetic polymer additives to enhance its performance even further. Such materials are called polymer-bitumen emulsions or rubber-bitumen emulsions.

Injection of polymer into bitumen emulsions is becoming more and more popular, since polymer-bitumen emulsions are obviously better for construction and repair of roads. Bitumen modification allows production of high quality emulsion, compliant with the high demands and high loads of modern roads. Modified water-bitumen emulsions improve stability and durability of road top and extend the temperature range of operation, elasticity and deformation stability. Research shows that bitumen, extracted after ten years of operation, shows little change of viscosity. The use of polymer-bitumen emulsion reduces the time of layer formation, however, additional adhesive additives are recommended to improve performance.

Water-bitumen emulsion can be modified in one of the three methods.

First method: injection of modifier into bitumen before emulsification.

Second method: injection of polymers into colloid mill at the stage of emulsion preparation.

Third method: mixing of two emulsions, where prepared emulsion is mixed with modifiers in the form of another emulsion.

Polymer bitumen emulsions are designed not only for road construction, but are also widely used for water-proofing of above and below ground structures, roofs etc. Water proofing materials made of water-bitumen emulsions protects structures from adverse effects of water.

UVB-1 bitumen emulsion unit, 1 m3/hour production capacity

The UVB-1 plant is designed for production of anionic and cationic bitumen emulsion used in repairs and construction of roads, as well as liquid rubber, which can be used for roofing. A 1 cubic meter per hour unit is ideal for small repair facilities with everyday needs of 6 – 9 tons of emulsion.

Bitumen emulsions were first used in Europe in the 1930s. Since then, the industry has seen many promising designs, which allowed to improve production efficiency and process, as well as product yield. At this time, bitumen emulsions of all types (anionic, cationic, water in oil, oil in water, fast, medium and slow setting) are without a doubt a promising material for various construction works. The number of processes where bitumen emulsions are used is growing. Application of these materials is highly profitable and reliable The number of technological processes which use bitumen emulsions one way or the other is growing.

Plants developed and manufacture by GlobeCore are highly efficient and feature high quality. The use of innovative technology saves user costs, at the same time ensuring the following:

  •      Reliable component parts;
  •      High quality of the product. The use of hydrodynamic mixer along with a colloid mill makes finely dispersed emulsions possible. Such product is in full compliance with industry standards, in many case exceeding their requirements;
  •      Automatic or semi-automatic control of the plant;
  •      Precise portioning of water phase and unique blending technology;
  •      customization;
  •      spare part depositories and worldwide customer support.

The UVB-1 bitumen emulsion units are semi-automated plants with components mounted on metal frame and connected with pipelines.

The rate of emulsion consumption depends on the type of surface treated. For asphalt surface, the consumption is 500 g/m2, in case of gravel the consumption grows to 1200 g/m2. Treatment of asphalt crumbs increases consumption up to 2000 g/m2.

Water-bitumen emulsion is a dark brown liquid. Emulsion is made by dispersing of bitumen in water with the addition of surfactants.

Bitumen emulsions are indispensible for various road construction tasks. It forms a protective layer for automobile roads (asphalt, gravel or concrete).

Specific areas of application are:

  •      creation of tack coat for road construction;
  •      permeation and surface treatment in road cover construction;
  •      creation of thin film wear layers;
  •      patch repairs (as part of mineral-emulsion mix).

Bitumen emulsions. General information. Principles

The main component of any such system is the binding. In normal conditions, bitumen is solid, therefore to mix it with mineral material, it must be made liquid by heating.

An alternative – emulsification of bitumen

The amount of solid material (bitumen) in emulsion is up to 70%. In the form of small particles it is suspended in water. General viscosity of the emulsion coincides with the viscosity of water phase; therefore it is liquid at room temperature.

Emulsion stabilized by emulsifiers.

An emulsifier molecule is bipolar. The “tail” of the molecule solves in the bitumen particles, while the “head” pushed away other emulsifier molecules and does not allow bitumen particles to coalesce. This is why the particles remain suspended in water (emulsion stability). When emulsion contacts mineral material, the system balance is disrupted because emulsifier leaves the surface of bitumen droplets and the destabilized emulsion envelops gravel. The difference of chanrges between the grave and the emulsifier pushes out the water which then evaporates. Bitumen road emulsion is used as a binding film creating material in repairs and construction of automobile roads, bridges, streets, overpasses and other structures. The technologies based on pouring of material (surface treatment, tack coat, patch repairs and permeation) use fast setting emulsion. It can be used in all moderate to warm climates from Europe to Asia.

Quality – the ability to ensure high quality without the need to heat mineral material and binding. This alone saves up to 40% energy in comparison with regular “hot” process.

Environmental considerations. Bitumen emulsion does not cause harmful emissions in the atmosphere, there is no risk of explosion or burns during transportation or bitumen solution processing.

Transportation of bitumen emulsion

Bitumen emulsions are transported in special tanks, bitumen carrier, cubic vessels and metal barrels.

Storage of bitumen emulsion

Bitumen emulsions are stored in special tanks or other cylindrical vessels. The vessels must be clean: must not contain residual emulsions, bitumen, POL or other acidic or alkaline materials.

Emulsion of different composition must not be mixed in one vessel. Tanks must be tightly closed to prevent ingress of foreign objects and evaporation of water. The temperature of storage must be at least 5°С.  If the volume of the emulsion is more than 1m3, the tanks should be equipped with special stirring agitators.

Our company offers special vertical emulsion storage tanks SBE and SMB to store emulsion and polymer modified bitumen respectively. These tanks are equipped with heating and circulation systems and can easily integrate into the existing production process of a facility.
