Asphalt and water have greatly differing surface tension, and they do not mix at room or high temperatures. However, when the emulsified asphalt equipment is subjected to high-speed mechanical centrifugation, shearing, and impact, it forms particles ranging from 0.1 to 5 micrometers and disperses them into a water medium containing surfactants (emulsifiers and stabilizers). Due to the surfactants' ability to adsorb onto the surface of the emulsified asphalt particles, it reduces the interfacial tension between water and asphalt, allowing the asphalt particles to disperse in the surfactant-containing water medium (forming a stable dispersion system in water). The dispersion system is brown, with asphalt as the dispersed phase and water as the continuous phase, and it has good fluidity at room temperature.

Important Precautions for the Use of Emulsified Asphalt Equipment

1. Prior to application, ensure the valve position on the equipment is correct. The hot asphalt added to the asphalt emulsion equipment must operate within the range of 160-180℃. The heating unit can be used for long-distance transportation or extended operation, but should not be used as a melting oil furnace.

2. When using the front console, the switch should be set to the front control. At this point, the rear console can only control the nozzle's up and down movement.
