市售的金属清洗剂常是由于防锈能力达不到各使用单位的要求,而影响以金属清洗剂代替汽油、煤油及有机溶剂清洗脏污零件这一新工艺的推广应用。我们在推广这一工艺时,也遇到了这种情况,零件经金属清洗剂洗涤后交检验,其表面不允许再作防锈处理,但得保证零件在检验期间(一般二至三天)不得生锈。市售的金属清洗剂很难达到这一要求,为此,我们进行了在金属清洗剂中再加一定量的金属缓蚀剂的试验,取得了较好的效果,现经
Commercially available metal cleaning agent is often due to the rust-proof capacity of less than the requirements of the use of the unit, which affects the metal cleaning agent instead of gasoline, kerosene and organic solvents to clean the dirty parts of the promotion and application of this new technology. We have encountered this situation in the promotion of this process. After the parts are cleaned by metal cleaners, they are inspected and their surfaces are not allowed to be rust-repellent. However, parts must be protected during the inspection (usually two to three days) Rusty. It is difficult to meet this requirement by the commercially available metal cleaning agent. Therefore, we have carried out the experiment of adding a certain amount of metal corrosion inhibitor to the metal cleaning agent and achieved good results.
