水膜置换型防锈油(俗称脱水防锈油)是一种能置换金属表面的水膜、防止金属表面腐蚀的防锈油。脱水防锈油除具有脱水性能外,还应起短期的临时防锈油作用。所以对防锈、腐蚀、重叠,抑制手汗等性能也必须有所要求,另外脱水防锈油与水(盐水、乳化液和水清洗液)的乳化能力应比较差,油中的脱水添加剂和防锈添加剂不应溶于水。这样在生产上有两大好处,一是可以大大延长油的使用寿命,而且当油中的含水量在特殊条件下偶尔达到相当高的比 Water film replacement rust-proof oil (commonly known as dehydration anti-rust oil) is a water film to replace the metal surface, to prevent corrosion of the metal surface anti-rust oil. Dehydration antirust oil in addition to dehydration, but also should play a temporary short-term anti-rust oil effect. Therefore, rust, corrosion, overlap, hand sweat inhibition and other performance must also be required, while the other anti-rust oil and water dewatering (salt water, emulsion and water cleaning fluid) emulsifying ability should be relatively poor, the oil dehydration additives and Antirust additives should not dissolve in water. This has two major benefits in the production, one can greatly extend the service life of oil, and when the oil in the water under special conditions occasionally reached a very high ratio
