摘　　要：为了解决冬季常温工业清洗中,由于水温低,造成水基清洗剂洗净率低、易发泡的问题,在3℃下研究了两种嵌段醇醚非离子与吉米奇阳离子表面活性剂的复配体系对多种油污的去污性能及其清洗液的泡沫行为,以及聚三元羧酸酯H5768、硼酸三乙醇胺酯的复配体系对钢材的缓蚀作用。开发了一种在低温下低泡、高效、防锈、环保的水基金属清洗剂,最佳配方是:氢氧化钠,10%~15%;无水偏硅酸钠,0.8%~2%;葡萄糖酸钠,5%~8%;H5768,2%~4%;硼酸三乙醇胺酯,1%~3%;PAA,1%~3%;WP172,5%~8%;RPE2520,2%~4%;吉米奇去油污季铵盐,0.8%~1.5%;水,51.5%~72.4%。在3℃及以上温度下清洗剂无泡,且能有效抑制清洗中由于油污皂化引起的泡沫,使用浓度5%,清洗时间5 min,对机械加工后工件及返修件洗净率可达99%以上,对铸铁、碳钢、合金钢有很好的防锈性能,且体系中的吉米奇阳离子表面活性剂可以使漂洗后的工件表面具有很好的疏水性,实现快速脱水、快速干燥,有效避免了干燥过程的返锈现象。各项性能符合JB/T 4323.1—1999标准。A water based metal cleaning agent which has low foam under low temperature,high efficiency,antirust and environment-harmless characteristics was researched and developed. The metal cleaning agent is composed of anhydrous sodium metasilicate 0. 8% - 2%,sodium hydroxide 10% -15%,sodium gluconate 5% - 8%,H5768 2% - 4%,boric acid triethanolamine ester 1% - 3%,PAA1% - 3%,WP172 5% - 8%,RPE2520 2% - 4%,C12022811 0. 8% - 1. 5%,water 51. 5. 0% -72. 4%. Above temperature of 3 ℃,it doesn’t foam and has a superior performance of defoaming and suppressing the foam caused by oil stains during cleaning process. The cleaning rate for oil stains is more than 99% when applied concentration is 5% at 3 ℃ for cleaning 5 min,which meets the standard JB/T 4323. 1—1999.
