We all know that stainless steel plate is not rusted, smooth surface, high plasticity, toughness, acid, alkali gas resistance, solution resistance, water resistance and other weak medium corrosion steel.
Some people want to engrave some patterns on the stainless steel plate to make it look more beautiful. Do you know how to etch the pattern on the stainless steel plate?
The principle of stainless steel etching or etching is to 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 as follows: First, the surface of stainless steel is coated with an anti-corrosion layer, and the part to be protected is protected and put into the spraying ferric chloride line. After the corrosion is completed, the anti-corrosion layer is washed off to form a pattern.
Stainless steel etching process flow is:
Stainless steel plates - Degreasing - Washing - Drying - Screen printing - Drying - Flooding - Etching Patterned leaves (sheets) Washing - Ink removal - Washing - Polishing - Washing - Coloring - Washing leaves (tablets) Hardening - Closure - Cleaning leaf (sheet) drying - inspection - completion.
Summary: Etched pattern boards are chemically etched on the surface of objects to etch out a variety of patterns. Based on the 8K mirror panel as the base plate, the surface of the object is further processed after the etching process. The color stainless steel etched plate can be processed by various complicated processes such as partial patterning, drawing, gold inserting, and local titanium gold. The etched plate achieves bright and dark patterns and brilliant colors.
