The bitumen emulsion1 unit consecutively blends components in hydrodynamic mixers2 at certain pressures and temperatures. Due to the unique design, the hydrodynamic mixer instantly blends component streams, which makes the unit compact and reduces energy consumption. The final stage of production of uniform water-bitumen emulsion occurs in a colloid mill3, which guarantees high quality of the product.
The unit features process control instrumentation which allows either manual or semi-automatic operation.
Water-bitumen emulsion is a dark brown liquid. Emulsion is made by dispersing bitumen4 in water with the addition of surfactants5.
Bitumen emulsions are indispensable 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 top construction;
creation of thin film wear layers;
patch repairs (as part of mineral-emulsion mix).
