Stainless steel lettering and stainless steel product solutions - There are many methods for processing on the surface of stainless steel, which can be roughly divided into two types: one is to treat stainless steel lettering to give it a surface gloss, and the other is to use the contrast of stainless steel nameplate gloss to form an artistic processing pattern; Another type is the artistic processing of adding color to the composition of patterns. Typical examples of using screen printing include etching and color spraying.light box maker melbourne
Etching processing method is to print an acid resistant protective film on the surface of stainless steel characters using a silk screen, and then etch it with ferrous chloride solution to form an artistic pattern. Spray color method is the process of spraying pigment particles after screen printing to form an artistic pattern on the surface of a pear peel sample.
In recent years, in order to adapt to the diverse uses of stainless steel and the increasingly high artistic requirements, colored "color art" processing methods have been developed and have become the mainstream in this field. In the methods of giving color to stainless steel characters, there are methods such as using screen printing color ink and firing it, as well as chemical coloring.
The process of chemical coloring art processing for stainless steel characters is as follows: stainless steel characters → silk screen printing → oxidation coloring → alkali treatment → finished product.
The etching art processing method for stainless steel characters involves the following steps: stainless steel characters → silk screen printing → etching → alkali treatment → oxidation coloring → finished product.
The process of spray color art processing for stainless steel characters is as follows: stainless steel characters → screen printing → etching → alkali treatment → screen printing → oxidation coloring → alkali treatment → finished product.
The chemical coloring method for stainless steel characters does not use pigments and dyes, but involves soaking the stainless steel in a heated concentrated chromium sulfate solution for chemical coloring. Its characteristic is good food resistance. The ink used in this processing method needs to have strong acid resistance, and generally uses UV vulcanized ink with special properties that are suitable for the processing technology.
