Definition and classification of defoamers

Defoamer is a chemical additive that can quickly destroy the surface tension of liquid, thus effectively inhibiting and eliminating foam. According to chemical composition, it can be divided into organosilicon, polyether, mineral oil, fatty acid salts, etc.

Background of application in the construction industry

In the construction industry, concrete mixing, wastewater treatment, cooling water system and other links often produce a lot of foam, affecting production efficiency and the environment.

Mechanism of action of defoamers

Destroy the surface tension of foam wall and make foam burst rapidly.Prevent the formation of new foam through infiltration and dispersion.
