How to treat the surface of the stainless steel filter

There are many ways to stop processing the surface of the stainless steel filter, which can be roughly divided into two types. One is to treat the stainless steel filter to make the surface brilliance, and use the brilliance contrast to compose the artistic processing of the picture; the other is the composition of the picture The artistic processing of the color conferred in. Exemplary examples of the use of screen printing are etching processing and color spray processing.

The etching process is to screen-print an acid-resistant protective film on the surface of stainless steel, and then etch it with ferrous chloride to form an artistic picture. The color spray method is to radiate pigment particles after screen printing to form a pear-like surface to form an artistic picture.

The chemical coloring method of the stainless steel filter does not use pigments and dyes. Instead, the stainless steel filter is immersed in a heated concentrated chromium sulfate solution to stop the chemical coloring. Its characteristic is good food resistance.
