The most popular field of stainless steel etching technology is the application of elevator decorative plates. From top hotels to general residential buildings, all kinds of SUS304 Champange gold Etched stainless steel decorative sheets can be seen on elevator decoration.
The process principle of SUS304 Champange gold Etched stainless steel decorative sheet is: using the strong oxidizing property of ferric chloride to corrode the surface of stainless steel, the trivalent iron element becomes a relatively stable divalent iron element; the specific production process is: first The stainless steel surface is coated with an anti-corrosion layer to protect the parts that need to be protected, and put it into the assembly line where the ferric chloride is sprayed. After the corrosion is completed, the anti-corrosion layer is washed off to form a pattern.
The key steps in the production of stainless steel etched plates are the surface coating and corrosion process.
The anti-corrosion protective layer of SUS304 Champange gold Etched stainless steel decorative sheet is generally made of special ink. The process of printing ink can be divided into two types according to the output and production cost. One is suitable for the production of products with uniform patterns and large production volume, which is called screen printing. The designer makes a standard stencil in a ratio of 1:1 according to the pattern to be made, and then uses a screen printing machine to brush an ink protective layer on the surface of the steel plate. The other is film sensitization, which uses the high-precision characteristics of film to make patterns on the surface of the steel plate. There is little difference in quality between the two methods, mainly limited by the cost of production.
