我厂原来用汽油清洗零件后进行电解加工 ,然后再用自来水冲洗,在30~#机械油中加热脱水。由于在电解过程中存在NaCl介质和30~#机械油脱水不完全,零件容易生锈。从1988年10月我们采用了82—10水基清洗剂除油除盐和SM-2脱水油(南京长江炼油厂生产)脱水新工艺取得了满意的效果。
I plant the original gasoline after cleaning parts for electrolytic processing, and then washed with tap water, heated in 30 ~ # mechanical oil dehydration. Due to the existence of NaCl in the electrolysis process and 30 ~ # mechanical oil dehydration is not complete, the parts are easy to rust. From October 1988 we have adopted 82-10 water-based cleaning agent degreasing and SM-2 dehydration oil (Nanjing Changjiang Refinery) dehydration of new technology and achieved satisfactory results.
