摘要
Disclosed is a chemical composition and a process for inhibiting corrosion and scaling on metal surfaces in industrial cooling water systems. The process includes the addition to the cooling water of from 10 to 200 ppm of an alkyl polyethoxy compound having a free carboxylate, sulfonate or phosphonate group. In some preferred embodiments, 10 to 500 ppm of a mineral oil is added to the water system, in addition to the polyethoxy compound.
