Abstract

A novel environmentally friendly type of scale inhibitor acrylic acid–allylpolyethoxy carboxylate (AQn) was synthesized. The antiscale property of the AQn copolymer towards Ca3(PO4)2 in the artificial cooling water was studied through static scale inhibition tests, The observation shows that Ca3(PO4)2 inhibition increases with increasing the degree of polymerization of AQn from 5 to 15, and the dosage of AQn plays an important role on Ca3(PO4)2 inhibition. The effect on the formation of Ca3(PO4)2 was investigated with combination of scanning electronic microscopy, transmission electron microscopy, X-ray powder diffraction analysis, respectively. Inhibition mechanism is proposed that the interactions between calcium ions and polyethylene glycol are the fundamental impetus to restrain the formation of the scale in cooling water systems.
