共聚物阻垢剂AA/AMPS制备及其性能研究

Study on the Synthesis and Performance of AA/AMPS Binary Copolymer

在水溶液中,以丙烯酸(AA)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)为原料,合成集膦酸基、羧酸基、磺酸基于一体的共聚物.探讨了钙容忍度、Fe2O3的分散性能、pH值等对共聚物阻垢性能的影响.研究表明,该阻垢剂有较好的阻CaCO3垢、Ca3(PO4)2垢能力及分散性能和缓蚀性能.

The copolymer is prepared from the monomers of acrylic acid （A.A） and 2-acrylarnido-2-methylpropanesulfonic acid （AMPS） in water. The effects of polymers concentration, Ca^2＋ concentration, pH, dispersant for ferric oxide and corrosion protection on the corresponding product＇s scale inhibiting performance have been studied. The results show that the copolymer possesses quite good effect on reducing scale depositions of CaCO2, Ca3 （PO4）2, capabilities of dispersing for ferric oxide and corrosion protection.
