本标准适用于矿物油为基础油加入适量的防锈剂、乳化剂而制得的产品。根据用途不同分为1号、2号,3号、4号,其中:1号防锈性较好;2号清洗性较好;3号极压性较好,4号是透明型的(适用于特种要求的金属加工冷却,亦可作内燃机冷却液)。本产品与水按一定比例混合时则成乳状液,具有防锈、清洗、极压性能,适用于金属加工切削等过程中作为冷却液使用。
This standard applies to mineral oil-based oil by adding the right amount of rust inhibitors, emulsifiers and products obtained. According to different uses, it can be divided into No. 1, No. 2, No. 3 and No. 4, among which: No. 1 is better in rust prevention; No. 2 is better in cleaning; No. 3 is better in pressure resistance and No. 4 is transparent In the special requirements of the metal cooling, but also for internal combustion engine coolant). The product is mixed with water when the emulsion is a certain proportion, with anti-rust, cleaning, extreme pressure performance, suitable for metal processing and cutting process as a coolant.
