The abundance of these resources gives Canada a robust comparative advantage in the industries that extract and process them,â said Michael Burt, Director, Industrial Economic Trends, and co-author of Adding Value to Trade: Moving Beyond Being Hewers of Wood.
An emulsion is a mixture of two or more liquids that are normally immiscible. Emulsions are part of a more general class of two-phase systems of matter called colloids.
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.
