磷化除锈工艺是一项新型除锈工艺。机电公司的工程技术人员在考察钢结构制造工艺中了解到淞滋县科委研制成的除油除锈磷化剂效果好,取回样品液,组织了现场示范及初步评议。在正式应用于钢铁产品之前,成立了试验研究小组,对除锈磷化液的pH值进行测定。按不同的配合比、不同的温度、不同的除锈程度与有油渍、无油渍的试件做除
Phosphating rust removal process is a new rust removal process. The engineering and technical personnel of the electromechanical company learned from the inspection of the steel structure manufacturing process that the deoiling and rusting phosphating agent developed by the Science and Technology Commission of the Zizi County had a good effect, retrieved the sample solution, and organized demonstrations and preliminary comments on the spot. Prior to the formal application of steel products, a pilot research team was established to determine the pH of the rust removing phosphating solution. According to different mixing ratios, different temperatures, different degrees of rust removal and greased, grease-free specimens
