Description

technical field

[0001] The invention relates to the technical field of metal surface treatment, in particular to a surface treatment agent for metal stamping parts, that is, a surface treatment process. Background technique

[0002] Metal surface treatment agent refers to the general term for various chemical agents for metal surface treatment. Metal surface treatment includes degreasing, rust removal, phosphating, antirust and other substrate pretreatments, which are prepared for metal coating technology and metal protection technology. The quality of substrate pretreatment has a great influence on subsequent coating preparation and metal use. big impact. At present, in the field of metal surface treatment, the phosphating process is the main method. The phosphating process is simple to operate and low in cost. After phosphating, a uniform and dense reaction film is formed on the metal surface. Therefore, it is widely used in the industrial field, especially in the field ...
