摘要
为了克服油基清防蜡剂存在的有毒、易燃、密度小等缺点,解决水基清防蜡剂存在的清蜡效率低、防蜡效果差等不足,研制出具有低毒、不易燃烧、防蜡效果好的YZ238防冻乳液型防蜡剂。该防蜡剂主要由1#、2#活性剂、蜡晶改进剂和有机溶剂组成。室内实验表明:该防蜡剂在最佳的配比条件下,稳定性≥270天,凝固点≤-30℃,静态防蜡率大于70%。
In order to solve problem of toxic,combustible,lower density for oil-base paraffin remover and inhibitor,and low paraffin removal efficiency,low control effect for water-base paraffin inhibitor,a new-type of antifreezing emulsion-type paraffin inhibitor have studied. The oil soluble wax inhibiting agent YZ238 was composed of No.1 and No.2 surfactants, thinner and organic solvents. Following results were obtained in laboratory: YZ238 as aqueous emulsions keep stable in >270 days, the freezing point less than -30℃, wax inhibiting rate in static state in flow state were more than 70%.
