在河南省机械局举办的润滑学习班上,大家介绍了三种机床除油渍的办法,供参考。1.把水加热到60～80℃,依次加入碳酸钠2％,磷酸钠2％,三乙醇3％,油酸铵2％;每加入一种化学药品,都要充分搅拌待溶解后,才能加入第二种,以免凝成“鸡蛋”状。清洗时,用干净棉纱沾此溶液清洗,稍待化学反应后,再沾一点去污粉擦拭即可。2.在每100公斤70～80℃的热水中,依次加入六六四合成洗涤剂2公斤,碳酸钠0.2公斤,亚硝酸钠1公斤,搅拌均匀即可。
In Henan Province, organized by the Bureau of Mechanical Lubrication classes, we introduced the three methods of machine tool degreasing, for reference. 1. The water is heated to 60 ~ 80 ℃, followed by the addition of 2% sodium carbonate, 2% sodium phosphate, 3% ethanol, ammonium oleate 2%; each added a chemical, to be fully stirred until dissolved Add the second, so as not to condense into “egg” shape. When cleaning, clean the cotton yarn with this solution to clean, wait for a chemical reaction, and then dip a little detergent can wipe. 2. In every 100 kilograms of 70 ~ 80 ℃ hot water, followed by adding six six four synthetic detergent 2 kg, 0.2 kg of sodium carbonate, sodium nitrite 1 kg, stir well.
