Etching method:
The etching processing method is to use screen printing acid-resistant protective film on the surface of stainless steel, and then etch with ferrous chloride solution to form an artistic pattern.
Spray paint method:
The spray color method is to spray pigment particles after screen printing to form a pear skin-like surface and form an artistic pattern.
crafting process:
The process of spray painting art processing method of stainless steel products is: stainless steel products→screen printing→etching→alkali treatment→screen printing→oxidative coloring→alkali treatment→finished product.
The process of etching art processing method of stainless steel products is: stainless steel products → silk screen → etching → alkali treatment → oxidation coloring → finished product.
The chemical coloring method of stainless steel does not use pigments and dyes, but immerses stainless steel in a heated concentrated chromium sulfate solution for chemical coloring, which is characterized by good food resistance. The ink used in this processing method must have very strong acid resistance. Generally, UV vulcanized ink with special properties suitable for the processing technology is used.
Stamping processing: Stainless steel products, especially stainless steel strips, are often the most primitive processing method in factories to use punching machines to stamp products. Stamping includes two methods: straight punching and stretching. Generally, the hardness is lower than 1/2 by stretching and bending, and the hardness is higher than 1/2 and more hard, and it is straight punching.
