【Abstract】 With cyclohexane as the dispersion medium, the oil and water being 1. 6,Span80-Tween80 as the emulsifier, the potassium persulfate as the initiator,polymer maleic anhydride-taurine -acrylic acid (MA-TA-AA) is synthesized and the performance of its scale inhibition is evaluated by scale static beaker tests of CaCO3, Ca3(PO4)2. The copolymer’s disperse property for Fe2O3 and effect on inhibition with amount of reagent, temperature, pH value and hardness has been explored. Its structure is characterized by IR. This synthesis technology, standing a favourable position nowadays, satisfies the demand of environmental protection. It can lessen the side reaction, reduce cost and improve the rate of production. The synthesized inhibitor contains excellent scale inhibition adapting to high temperature, high hardness, high basicity and a wide range of pH.更多还原
