Heated bitumen yields the superior position to bitumen emulsion in road construction projects. Emulsions have better adhesive properties, are more easily spread over the road surface cover, and can be laid on a damp base. \u00a0Due to high penetration rates, emulsions easily fill the cracks and irregularities in the roadway.<\/p>\n
Modern, technologically advanced equipment is required for the quality production of bitumen emulsion products. \u00a0The production line for manufacturing bitumen emulsion should produce a stable product that (1) does not break down into water and bitumen during storage and transportation and (2) when \u00a0received at the job site, the bitumen emulsion should have maintained its performance parameters as to its specified viscosity, acidity, adhesion and other physicochemical properties.<\/p>\n
When selecting bitumen and emulsion equipment you should primarily choose the type of operational cycle that best meets the needs of your company. \u00a0The operational cycle may be be continuous or periodical. \u00a0In continuous plants, the water solvent of emulsifier and acids are prepared separately and then they are blended with the bitumen. \u00a0Such plants are relatively simple and can offer more variants and options \u00a0when selecting such equipment. \u00a0In turn the bitumen and emulsion batch plants do not require prior preparation of the solutions, allow the easy correcting of the recipe in place, and they are easy-to-use.<\/p>\n
In general terms, any equipment for manufacturing bitumen emulsion consists of five (5) major components: (1) production line, the \u201cheart\u201d of which is a disperser and a mill; (2) vessels with reagents; (3) vessels for bitumen storage and finished emulsion (4) high tech pipelines and (5) a control system.<\/p>\n
The quality of the bitumen emulsion is provided in the first place with the reduction the ratio of bitumen and mixing consistency of the emulsion components in the blending line. It is an industry known fact \u00a0that something like bitumen emulsion can be prepared with the help of a one gear-type pump that is used as a mixer for an enormous quantity of emulsifier. \u00a0This product however, as an emulsion most likely will exist for a couple of minutes and then it will be broken down into bitumen and water.<\/p>\n
Colloid mills, that are used as mixers, provide high quality and \u00a0homogeneity of the prime dispersion components. \u00a0These mills should be chosen very carefully. \u00a0If the owner of the plant reaches a decision to save on the quality of grinding when buying a mill of a lower price range, than he will inevitably be faced with the problem of emulsion stability. \u00a0This problem however, could be easily solved by means of increasing the quantity of the \u00a0emulsifier and acids (for reducing PH). \u00a0As a result, this will lead to substantial rise of product costs because the price for reagents is very high. \u00a0The \u201cover acidity<\/i>\u201d of bitumen emulsion will lead to accelerated corrosion of metal surfaces of vessels and pipelines used in bitumen production and storage.<\/p>\n
The dosing system is a very important aspect of the bitumen emulsion production line. \u00a0Compliance of bitumen emulsion with the given recipe depends very much on the accurate work of the dosing system. Dosing with low cost equipment components is not very accurate and it cannot be adjusted during the work process, nor it can be corrected according to indirect parameters (e.g. frequent rotation of the inlet pump shaft). \u00a0It is therefore, extremely hard to provide high accuracy with this equipment as the volume of pumped bitumen with the same values of pump rotation depends too much on the temperature, inlet and outlet pump pressure, and physicochemical properties of the bitumen. \u00a0In practice, even a small mistake of 1% bitumen dosing greatly influences the working properties of some kinds of bitumen emulsion. \u00a0Special flow meters are installed in bitumen and emulsion equipment of the middle and high price ranges. \u00a0They allow for not only controlling the volume of the supplied components, but also introduce feedback and automatically correct the work of the inlet pump.<\/p>\n
Vessels for emulsifier, acid, and adhesive additives can be mounted separately or can be supplied as chemical reagents mounted inside of the production block. \u00a0The last variant is more preferable because less length of inlet pipelines increases the stability of inlet line work. \u00a0Because of the quality of the heat insulation in the production module, the unit can easily sustain the desired temperature of the reagents that are specified in the operating manuals.<\/p>\n
As a rule, a vessel for the storage of ready-made emulsion has a cylindrical form and it is installed horizontally or vertically. \u00a0Practice has shown that a vertical vessel is more preferable as with some time a bitumen crust on the surface of bitumen emulsion will arise. \u00a0The crust preserves its integrity when the bitumen level changes in the vertical vessel and prevents water evaporation from the emulsion. \u00a0At the same time, the protecting crust in the horizontally placed cylindrical vessel is constantly breaking thereby not providing protection against unwanted evaporation.<\/p>\n
We highly recommend discussing possible variants with the equipment manufacturer and\/or an authorized dealer. \u00a0\u00a0You and your dealer or manufacturer should take into account the diversity of factors that help shape your decision making. \u00a0\u00a0It should be borne in mind that when choosing equipment for manufacturing bitumen emulsion, the availability of several variants and solutions that are offered to \u00a0the customer of technical equipment can make it \u00a0difficult to determine the right choice. \u00a0GlobeCore<\/i><\/b> employees always know what the right choices are and will always help you to make the choice that is \u00a0right for your business and operation.<\/p>\n","protected":false},"excerpt":{"rendered":"
