摘　　要：针对磷锌预膜剂在使用过程中存在的问题,开发出由葡萄糖酸钠、硫酸锌、丙烯酸-丙烯酸酯-磺酸盐三元共聚物、三乙醇胺复配而成的无磷环保循环冷却水预膜剂。采用硫酸铜滴定法对预膜效果进行了检测,并对预膜剂使用浓度和使用条件进行了优化。结果表明,预膜剂的最佳使用浓度和使用条件:预膜剂最佳投加量500 mg/L;浊度﹤30 NTU,常温,自然pH。将该预膜剂用于实际水处理系统,取得了满意效果。In order to solve the problem existed in the use of phosphorus and zinc pre-film agent.The nonphosphorus,environmental protection,cooling water pre-filming agent made from sodium gluconate,zinc sulfate,acrylic-acrylatesulfonate terpolymer,triethanolamine has been developed.The pre-filming effect is detected by copper sulfatetitration,and the usable concentration and conditions are optimized.The results show that the optimumconcentration and conditions of the pre-filming agent are as follows：the dosage is 500 mg/L,turbidity〈30 NTU,room temperature,and natural pH.The practical application of this pre-filming agent to water treatment systemsachieves satisfactory effect.
