常用的钢铁制件防锈剂主要有水剂、油剂、气相剂三种,有单独使用的,也有复合使用的。加工工序间大多采用微碱性的高浓度亚硝酸钠水剂防锈,有时也添加适量的苯甲酸钠、三乙醇胺等。事实证明,这些溶液不论冷涂或热涂,其效果都不很理想,在成都地区甚至只能维持几天,经常给精密制件的生产带来损失。因此,设法提高防锈液工序防锈效力实属必要。

Commonly used steel parts rust inhibitor mainly water, oil, gas phase three, used alone, but also the composite use. Most of the processing between the use of slightly alkaline sodium nitrite high concentration of rust-proof agent, and sometimes also add the right amount of sodium benzoate, triethanolamine and so on. Facts have proved that these solutions, whether cold or hot coating, the effect is not very satisfactory, and even in Chengdu, can only last for a few days, often to the loss of precision parts production. Therefore, trying to improve anti-rust liquid anti-rust efficiency is necessary.
