Scale InhibitorsCopolymers of hydroxypropyl acrylate and acrylic acid, due to their excellent performance, can not only effectively inhibit the formation and deposition of calcium carbonate and calcium phosphate scales but also inhibit zinc salt deposition and disperse iron oxide. Meanwhile, they are widely used in water treatment.With the continuous development of water treatment technology and the research and development of various new water treatment agents, fluorescent tracing water treatment technology has been practically applied. A simple method to obtain fluorescent polymers is through the copolymerization of acrylic acid, hydroxypropyl acrylate polymers, and fluorescent monomers.
