Everyone has heard that asphalt is mainly used for pavement laying, so what is asphalt emulsifier? Many people may not know much about it. In fact, asphalt emulsifier is also a material for road construction and can be used for road surface maintenance. Of course, the role of asphalt emulsifiers is not limited to these, and Kain Chemical also introduces them in detail below. What exactly is an asphalt emulsifier? What is the function of asphalt emulsifier?
What is an asphalt emulsifier?
Asphalt emulsifier is the road asphalt that is usually used at high temperature, after mechanical stirring and chemical stabilization (emulsification), it is diffused into water and liquefied into a very viscous at room temperature A road construction material with low fluidity and good fluidity. It is dispersed in an aqueous solution containing an emulsifier in the state of fine droplets to form an asphalt emulsion in the state of oil-in-water or water-in-oil.
How to use asphalt emulsifier?
In the process of road construction, 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 require high temperature at all. And hot lead to toxic gas emissions. Asphalt emulsifier can also be used at normal temperature, and can also be used with other materials in any state. It can be reduced to continuous asphalt and the water is completely removed, so that the final strength of the road material can be formed, and the softness of the road surface can be enhanced, which is not easy to deform and crush.
What is the role of asphalt emulsifier?
1. Used for road upgrade and maintenance, such as cold mix and slurry seal. Asphalt emulsifier can also be used in new road construction, such as adding asphalt emulsifier to asphalt road, it can be more stable and not easy to stratify.
2. Used for leak-proof, seepage-proof and moisture-proof in construction projects. For example, adding asphalt emulsifier to the warehouse floor will make the warehouse floor difficult to penetrate, and the objects in the warehouse will not be easily wet and damaged.
3. It is used to make thermal insulation materials. The emulsified asphalt expanded perlite thermal insulation material is based on emulsified asphalt, and expanded perlite is added. It is made by stirring and pressing at room temperature.
4. When the asphalt emulsifier is used to produce fuel oil and coal tar asphalt is directly burned, it is difficult to burn completely due to its condensed aromatic ring structure and high catharsis. It is easy to produce a large amount of black smoke and cause environmental pollution. The emulsification of tar pitch as fuel has significant advantages over its direct combustion, which can reduce the smoke carbon 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 All have good cohesion, the raw materials are easy to get and the price is low, and they have been used for anticorrosion of metal and non-metal materials and their products long ago.
6. Used for soil improvement and plant cultivation. Asphalt emulsifier is a natural soil structure improver.
