Asphalt emulsifier is a surfactant, which is a type of emulsifier. Asphalt emulsifier is a key raw material for the production of asphalt emulsion, that is, emulsified asphalt. Because "asphalt emulsifier" is not a daily necessity, you may not know much about it. If you want to know more about this knowledge, you can read this article carefully!

What is the role of asphalt emulsifier?
As we all know, asphalt and water are two substances that are immiscible with each other and cannot form a relatively stable equilibrium system. Emulsified asphalt cannot be produced without an emulsifier. The role of asphalt emulsifier is to reduce the surface tension of asphalt and mix asphalt and water to form a new liquid. The proportion of asphalt emulsifier in emulsified asphalt is very small, generally between 0.2-2.5%. The amount of asphalt emulsifier used is not much, but the role it plays is very important. It realizes the transformation from asphalt to asphalt emulsion.
The emergence of asphalt emulsifier makes asphalt simple and convenient in some construction applications. For example: cold primer, penetrating oil, adhesive oil, slurry seal, micro surfacing, Cape seal, fine surfacing, etc. for building waterproofing.
