With the rapid development of highway construction and the increase in demand for asphalt, barreled bitumen has been widely used for its convenient transportation and easy storage. In particular, most of the high-performance imported bitumen used in high-grade highways is in barrel form, which requires an bitumen melter equipment with fast melting speed, clean debarreling, and prevention of asphalt aging.
The upper part of the debarreler of the bitumen melter equipment is hotter, and each barrel is directly heated by the heat transfer oil coil. The barrel wall directly bears the heat radiation of the heating coil. The asphalt is cleanly and sensitively debarreled, and there will be no waste of asphalt hanging barrels. According to the principle of layered heating, four-layer heating technology is adopted, with single inlet and single outlet of heat transfer oil, and high thermal efficiency of heating; at the same time, the waste heat of combustion exhaust gas is used for secondary heating, and power is effectively used; the debarreler body is insulated with high-quality rock wool material. It is suitable for various types of imported and domestic barrels, and the deformation of asphalt barrels will not affect production.

Mixed materials: Mix the polyurethane resin and pigment in a certain proportion to ensure the quality of the coating.
Construction tools: Usually a spray gun or sprayer is used for construction. Before construction, the state and pressure of the nozzle should be checked to see if they are normal.
Spraying direction: Pay attention to the spraying direction during construction, and try to make the particles perpendicular to the surface.
Protection time: After construction, protection should be carried out for the prescribed time to avoid damage to the coating due to external forces.
In general, the construction of sand-containing mist seal is relatively simple, but attention should still be paid to details and quality control. Reasonable construction methods and precautions can ensure the quality and service life of the coating.

The surface tension of asphalt and water is very different, and they will not be miscible with each other at room temperature or high temperature. However, when the emulsified asphalt equipment is subjected to mechanical actions such as high-speed centrifugation, shearing, and impact, the emulsified asphalt equipment makes it into particles with a particle size of 0.1~5μm, and dispersed in a water medium containing a surfactant (emulsifier-stabilizer). Since the emulsifier can be directional adsorbed on the surface of the emulsified asphalt equipment particles, the interfacial tension between water and asphalt is reduced, so that the asphalt particles can form a stable dispersion system in water. The emulsified asphalt equipment is an oil-in-water emulsion. This dispersion system is tea brown, with asphalt as the dispersed phase and water as the continuous phase, and has good fluidity at room temperature.
In a sense, emulsified asphalt equipment dilutes asphalt with water, thereby improving the fluidity of asphalt.
