There are two main modification methods for thermal oil asphalt tanks: external mixing method and internal mixing method. The external mixing method is to first prepare an ordinary thermal oil asphalt tank, then add a polymer latex modifier to the ordinary Jiangxi thermal oil asphalt tank, and mix and stir to make it. The polymer emulsion is usually CR emulsion, SBR emulsion, acrylic emulsion, etc. . The internal mixing method is to first mix rubber, plastic and other polymers and other additives into hot asphalt, and then mix them evenly and cause necessary interaction between the polymer and asphalt to obtain polymer-modified asphalt, and then go through the emulsification process. To produce modified asphalt emulsion, the polymer commonly used in the internal mixing method is SBS. If the asphalt material is stirred and stopped for the same amount of time, clear the surface of the stirring barrel, add clear water, and rinse the mortar. Then sweep away the water, keeping in mind that there should be no accumulation of water in the bucket to prevent the formula from causing changes, or even the steps such as the station to cause rust. During use, everyone must pay attention to many minor steps to avoid unnecessary slippage in the operation of the machine.

Operation experience of thermal oil asphalt tank:
The surface tensions of thermal oil asphalt tanks and water are very different, and they are not miscible with each other at normal or high temperatures. When the thermal oil asphalt tank machine is subjected to mechanical results such as rapid centrifugation, shearing, and impact, the thermal oil asphalt tank machine turns it into particles with a particle size of 0.1~5 μm, and is scattered into particles with surfactants (emulsifiers-stabilizers) In the water medium, because the emulsifier can be directionally adsorbed on the surface of Jiangxi emulsified asphalt machinery particles, it reduces the interfacial tension between water and asphalt, allowing the asphalt particles to form a stable scattered system in the water. The thermal oil asphalt tank machinery is oil-in-water. of emulsion. Such a scattered system is brown in color, with asphalt as the dispersed phase and water as the continuous phase, and enjoys superior fluidity at room temperature. In a sense, the thermal oil asphalt tank machinery uses water to "dilute" the asphalt, so the fluidity of the asphalt is corrected.
The thermal oil asphalt tank is made by hot-melting the base asphalt and mechanically scattering light asphalt particles in an aqueous solution containing an emulsifier to form a liquid asphalt material. The cement thermal oil asphalt tank mortar used in the slab ballastless track construction structure uses cationic thermal oil asphalt tank. Because of the flexibility and durability of the cement thermal oil asphalt tank mortar, polymers are often used to modify the asphalt.
