An emulsifier allows for miscibility between two substances that do not normally mix together. An example of this is the lecithin in egg yolk, which is used to allow the oil and vinegar to mix together to form an emulsion. Normally, without the lecithin, oil and vinegar would separate, and would never mix.
In the production of asphalt emulsion, water is treated with an emulsifying agent and other chemicals and is pumped to a colloid mill along with asphalt. The colloid mill breaks the asphalt up into tiny droplets. The emulsifying agent migrates to the asphalt-water interface and keeps the droplets from coalescing.The emulsion is then pumped to a storage tank. Asphalt emulsions are very complicated and use a lot of chemistry to get the emulsion properties desired.he emulsifying agent migrates to the asphalt-water interface and keeps the droplets from coalescing.
