Everyone has heard that asphalt is mainly used for paving roads, so what is asphalt emulsifier? Many people may not know much about it. In fact, asphalt emulsifier is also a material in road construction and can be used for road surface maintenance. Of course, the functions of asphalt emulsifiers are more than these. Kain Chemical also introduces them in detail below. What exactly is an asphalt emulsifier? What does asphalt emulsifier do?
What is asphalt emulsifier?
Asphalt emulsifier is a method of mechanical stirring and chemical stabilization (emulsification) of road asphalt that is usually used at high temperatures. It is diffused into water and liquefied into a very viscous form at room temperature. It is a road construction material with low fluidity and good fluidity. It is dispersed in an aqueous solution containing an emulsifier in the form of fine droplets, forming an oil-in-water or water-in-oil asphalt emulsion.
How to use asphalt emulsifier?
In the road construction process, asphalt emulsifier is a safer and more environmentally friendly emulsifier than hot asphalt. The process of asphalt emulsifier is more environmentally friendly and does not cause high temperatures at all. After heating, it will cause the emission of toxic gases. Asphalt emulsifier can also be used at room temperature or with any other material. It can be restored to continuous asphalt and the moisture is completely eliminated, so that the final strength of the road material can be formed, which enhances the softness of the road surface and is not easily deformed and crushed.
What is the role of asphalt emulsifier?
1. Used for road upgrade and maintenance, such as cold mix and slurry seal. Asphalt emulsifiers can also be used in new road construction. For example, adding asphalt emulsifiers to asphalt roads can make them smoother and less likely to delaminate.
2. Used to prevent leakage, seepage and moisture in construction projects. For example, adding asphalt emulsifier to the warehouse floor will make the warehouse floor less permeable and prevent objects in the warehouse from getting wet and damaged.
3. Used to manufacture thermal insulation materials. Emulsified asphalt expanded perlite thermal insulation materials use emulsified asphalt as a cementing material and add expanded perlite. It is produced by stirring and pressing at room temperature.
4. When directly burning asphalt emulsifier to produce fuel oil, coal tar, and asphalt, it is difficult to burn completely due to its condensed aromatic ring structure and high cat content. It is easy to produce a large amount of black smoke and cause environmental pollution. When tar asphalt is emulsified and used as fuel, it has significant advantages over direct combustion. It can reduce the soot value and save fuel consumption.
5. Anti-corrosion asphalt used for metal and non-metal materials and their products has waterproof, acid-proof, alkali-proof and anti-bacterial properties, and is compatible with metal and many non-metal materials They all have good bonding power, and the raw materials are easy to obtain and cheap. They have been used for the anti-corrosion of metal and non-metal materials and their products a long time ago.
6. Used for soil improvement and plant cultivation. Asphalt emulsifier is a natural soil structure improver.
