表面活性剂的复配及其在除油清洗中的应用

Composition and Application of Surfactants as Degreasing Agent

通过对几种非离子和阴离子表面活性剂的除油效果进行比较,筛选出了适用于金属除油的壬基酚聚氧乙烯醚TX-10等表面活性剂.通过正交试验,确定了四种表面活性剂之间最佳协同增效配比为TX-10：MOA-5：FMES：LAB=4：1：3：1.将该配比的除油剂用于金属表面除油,最佳的除油湿度为50～60℃,除油时间控制在5min.

The oil-removal effect of nonionic and anionic surfactants were compared, nonylpheuol potyoxyethylene （TX- 10 ）, fatty alcohol polyoxyethylene ether （ MOA-5 ）, fatty acid methyl ester ethoxylates sulfonate （FMES）, twelve alkyl benzene sulfonic acid （LAB） were selected to be applicable to metal surface degreasing agent. Through orthogonal test, the optimum synergistic ratio of these four kinds surfactant is TX-10 ： MOA-5 ： FMES ： I,AB=4 ： 1 ： 3 ： 1. The de,easing temperature is 50-60℃, degTeasing time should be controlled in 5min.
