what is container-type bitumen emulsion plants?
Release Time:2023-11-29
There are two main types of modification methods for container-type bitumen emulsion plant: external mixing method and internal mixing method. The external mixing method is to first make a basic container-type bitumen emulsion equipment, and then add a polymer latex modifier to the basic Shanxi container-type emulsified bitumen equipment, and mix it. The polymer emulsion usually appears as CR emulsion, SBR Emulsions and acrylic emulsions, etc. The internal mixing method is to first mix rubber, plastic and other polymers and other additives into the hot cold-mix colored bitumen. After mixing evenly and producing a certain interaction between the polymer and the cold-mix colored bitumen, the polymer-modified bitumen is obtained. Then the modified bitumen emulsion is produced through the emulsification process. The polymer commonly used in the internal mixing method is SBS. If the cold mix bitumen material is mixed and then shut down for an hour, clean the surface of the mixing barrel, add water, and wash the mortar. Then drain the water, keeping in mind that there is no accumulation of water in the bucket to prevent changes in the recipe or even rusting of the station and other programs. When following them, everyone knows to be cautious about many small procedures to avoid unnecessary waste in the work.

Reasons why containerized bitumen emulsion equipment works:
    The surface tension damage of container-type emulsified bitumen equipment and water is very different, and they are not miscible with each other at normal or high temperatures. When the container-type bitumen emulsion plant undergoes high-efficiency centrifugation, shearing, impact and other equipment, the container-type emulsified bitumen equipment will turn it into particles with a particle size of 0.1~5μm, and disperse them to contain surfactants (emulsifier- - Stabilizer) in the water medium, because the emulsifier can be adsorbed on the surface of Shanxi emulsified cold-mix colored bitumen facility particles at fixed points, it reduces the interfacial tension between water and cold-mix colored bitumen, allowing the cold-mix colored bitumen particles to form in water. With stable emission standards, container-type bitumen emulsion equipment is an oil-in-water emulsion. This emission standard is brown, cold-mixed colored bitumem is the dispersed phase, water is the continuous phase, and has correct fluidity at room temperature. Containerized emulsified bitumen equipment and facilities In a sense, containerized bitumen emulsion equipment and facilities use water to "disperse" cold-mix colored bitumen, thus correcting the fluidity of cold-mixed colored bitumen.
The container-type emulsified bitumen equipment hot-melts the base cold-mix colored bitumen and disperses it through the equipment into small cold-mix colored bitumen particles in an aqueous solution containing emulsifier to form a liquid cold-mix colored bitumen material. The cement container-type emulsified bitumen equipment mortar for slab ballastless track layout uses cationic container-type emulsified bitumen equipment. In order to correct the elasticity and reliability of the cement container-type emulsified bitumen plant mortar, polymers are often used to modify the bitumen.
