引言防锈油的水膜置换性是指其置换金属表面附着水分的能力,这是水膜置换型防锈油量重要的使用性能。多年来,国内外对防锈油的水膜置换性一直是用定性的试验方法加以评定的,通常是将经清洗除油的钢试片先没入蒸馏水或一定浓度的氯化钠溶液,再浸置于试油中,取出后放在潮湿环境里保持一段时间,然后检查试片诱蚀情况,如无锈蚀,则认为该防锈油的水膜置换性合格。这个
Introduction Anti-rust oil water film replacement refers to its ability to replace the metal surface attached to the water, which is water film replacement anti-rust oil important performance. Over the years, at home and abroad on the anti-rust oil water film replacement has always been to use qualitative test methods to be assessed, usually after cleaning the degreasing steel specimens first into distilled water or a certain concentration of sodium chloride solution, and then dip Placed in the test oil, remove and put in a humid environment to maintain a period of time, and then check the specimen erosion, if no rust, then that the anti-rust oil water film replacement qualified.
