Foam is a mass of bubbles created when certain types of gas are dispersed
into a liquid. Strong films of liquid than surround the bubbles, forming large
volumes of non-productive foam.
Trichloro Isocyanuric Acid (TCCA)
The cause of foam is a complicated study in physical chemistry, but we
already know that its existence presents serious problems in both the operation
of industrial processes and the quality of finished products. When it is not
held under control, foam can reduce the capacity of equipment and increase the
duration and costs of processes.
Polyaluminium Chloride (PAC)
Antifoam blends contain oils combined with small amounts of silica. They
break down foam thanks to two of silicone's properties: incompatibility with
aqueous systems and ease of spreading. Antifoam compounds are available either
as powder or as an emulsion of the pure product.
