Method for processing precision Stainless steel tube Surface

There are many methods for processing on the Surface of precision Stainless steel tubes, which can be roughly divided into two types. One is to treat the precision Stainless steel tube to have a Surface gloss, and the art processing using the gloss contrast to form a pattern; the other is in the pattern The artistic processing that gives color to the composition. Typical examples in which the screen printing method is used are etching processing and ink color processing. 

The etching process is to screen the acid-resistant protective film on the Surface of the precision Stainless steel tube, and then etch it with a ferrous chloride solution to form an artistic pattern. The spray color method is to spray the color particles after screen printing to form a pear-like Surface to form an artistic pattern.

In recent years, in order to adapt to the diversification of the use of precision Stainless steel tubes and increasingly high artistic requirements, the development of color-colored "color art" processing methods has become the mainstream in this field. Among the methods for imparting the color of a precision Stainless steel tube, a method of performing firing using screen printing of a color ink and a chemical coloring method are included.

The chemical coloring art processing method of precision stainless steel pipe products is: 

Precision stainless steel pipe products → silk screen → oxidation coloring → alkali treatment → finished product. The process of etching art processing of precision stainless steel pipe products is: 

Precision stainless steel pipe products → silk screen → etching → alkali treatment → oxidation coloring → finished product. The process of the spray color art processing method of precision stainless steel pipe products is: 

Precision stainless steel pipe products → silk screen → etching → alkali treatment → silk screen → oxidation coloring → alkali treatment → finished product.

The chemical coloring method of precision Stainless steel tubes, instead of using pigments and dyes, is to soak the precision Stainless steel tube in a heated concentrated chromium sulfate solution for chemical coloration, which is characterized by good food resistance. The ink used in this processing method has a very strong acid resistance, and generally uses a UV-curable ink having a special property compatible with the treatment process.
