Emulsified asphalt equipment pays special attention to the detailed operation process
Release Time:2023-12-04
There are two main types of modification methods for emulsified asphalt equipment: external mixing method and internal mixing method. The external mixing method is to first make a basic emulsified asphalt equipment, then add a polymer latex modifier to the basic emulsified asphalt equipment, and mix and stir to make it. The polymer emulsion usually appears as CR emulsion, SBR emulsion-related acrylic emulsion, etc. The internal mixing method is to first mix rubber, plastic and other polymers and other additives into the hot colored asphalt. After mixing evenly and discovering the absolute reaction between the polymer and the colored asphalt, the polymer modified asphalt is obtained. The next step is to Modified asphalt emulsion is created through emulsification art, and the polymer commonly used in the internal mixing method is SBS. If the colored asphalt material is stopped for an hour after mixing, clean the surface of the mixing barrel, add clean water, and scrub the mortar clean. Next, drain the water, making sure there is no accumulation of water in the bucket to prevent changes in the recipe or even rust in the operation process such as the website. During the process, everyone knows to pay special attention to many small operation procedures to avoid unnecessary losses to their own operations.

Operation process of emulsified asphalt equipment:
The surface tension damage of emulsified asphalt equipment and water is quite different, and they are not easily miscible with each other at normal or high temperatures. When the emulsified asphalt equipment undergoes mechanical action such as centrifugation, cutting, and impact, the emulsified asphalt equipment turns into particles with a particle size of 0.1~5 μm, and is distributed into the water containing surfactant (emulsifier-stabilizer) In the medium, the emulsifier can be directionally adsorbed on the surface of the emulsified colored asphalt equipment particles, thus reducing the interfacial tension between water and colored asphalt, allowing the colored asphalt particles to form a happy distribution system in the water. The emulsified asphalt equipment and equipment are oil-in-water. of emulsion. This type of distribution system is brown, with colored asphalt as the dispersed phase and water as the continuous phase, and enjoys excellent fluidity at room temperature. Emulsified asphalt equipment and facilities In a sense, emulsified asphalt equipment and facilities use water to "bend" the colored asphalt, thus regulating the fluidity of the colored asphalt.
Emulsified asphalt equipment hot-melts basic colored asphalt and mechanically distributes tiny colored asphalt particles in an aqueous solution containing emulsifier to form a liquid colored asphalt material. The cement emulsified asphalt equipment mortar used in slab ballastless track construction uses cationic emulsified asphalt equipment. The purpose is to adjust the elasticity, toughness and durability of the cement emulsified asphalt equipment mortar. Polymers are often used to modify the asphalt.
