Stainless steel etched plates are etched with various patterns on the surface of stainless steel by chemical methods. With an 8K mirror panel, drawing board, and sandblasting board as the bottom plate, the product’s exterior is further processed after etching treatment. The stainless steel etched plate can be processed with various complex processes such as local texture, wire drawing, gold inlay, partial titanium gold, etc. The stainless steel etching plate realizes the effect of light and dark patterns and brilliant colors.
These etched plates have the luster and strength typical of metal and are colorful and durable. The stainless steel etched plate has a long service life, high durability, and does not produce any toxic and harmful substances.
The process flow of the etching plate is:
Stainless steel raw plate – degreasing – water washing – drying – screen – printing – secondly drying – water immersion – etching pattern leaf washing – ink removal – secondly water washing – polishing – third water washing – coloring – water washing leaf hardening treatment – sealing treatment – cleaning leaf drying – inspection – product
Colored stainless steel etched plate decoration generally uses 0.6-2mm different thickness plates of 201 or 304 material. According to the thickness of the stainless steel plate and the decorative part, there are two common installation methods. One is with a keel and bottom plate, and the other one is with a keel without a bottom plate. In the experience of many installations, panels with a thickness of less than 1.2mm are mostly installed with a keel and a bottom plate. Therefore, panels with a thickness greater than 1.2mm are mostly installed with a keel and no bottom plate. The former is mostly used on indoor curved cladding or places with better moisture-proof and waterproofing, If facade decoration is without rain, the keel adopts a wooden keel, angle steel welded keel, or light steel keel. The latter is mostly used for outdoor wall cladding decoration, and the keel adopts an angle steel welding keel and a light steel keel.
The principle of stainless steel etching or corrosion: use the strong oxidizing property of ferric chloride to corrode the surface of stainless steel, and the trivalent iron element becomes a relatively stable divalent iron element.
The specific production process is: first coat the anti-corrosion layer on the surface of the stainless steel, protect the parts that need to be protected, put it into the assembly line where ferric chloride is sprayed, and wash off the anti-corrosion layer after the corrosion is completed to form patterns.
