Scale inhibition process.

摘要

A method for inhibiting the formation of scale formed primarily from amorphous silica in an aqueous system comprises the addition of a phosphinopolycarboxylic acid inhibitor. The inhibitors may be homopolymeric or copolymeric or a mixture of the two. The preferred inhibitors include phosphinopoly(meth) acrylic acids and their salts and phosphino acrylic/2-acrylamido-2-methyl propane sulphonic acid copolymers.
