Stainless steel etched board, with 8K mirror board, wire-drawing board, sandblasting board as the bottom plate, through chemical methods, the surface of stainless steel corrosion patterns.After etching, the stainless steel plate is further processed, such as local and grain, wire-drawing, gold embedding, local titanium gold and other complex processes.Stainless steel etching plate to achieve the pattern of light and dark, colorful effect.
Stainless steel etching principle: the use of ferric chloride of strong oxidation, the surface of stainless steel is corroded, iron trivalent elements become relatively stable iron elements.The specific production process is: first in the stainless steel surface coated with anti-corrosion layer, will need to protect the part of protection, put it into the spraying ferric chloride pipeline, corrosion finished will be anti-corrosion layer washed off, forming patterns.
The specific process of stainless steel plate etching is as follows:
1. Etching pre-treatment, which is the key process to ensure the screen printing ink has a good adhesion to the metal surface, so it is necessary to completely remove the grease and oxidation film on the metal etching surface.
2, oil removal should be based on the workpiece oil pollution plan, before screen printing to remove the oil, ensure the effect of oil removal.
3, in addition to the oxidation film according to the type of metal and film thickness of the choice of good etch solution, to ensure that the surface clean.
4, before screen printing to dry, if there is water, it will affect the ink adhesion, and affect the effect of subsequent etching or even out of shape, affect the decorative effect.
5, screen printing according to the printing needs to make standard graphics screen plate.In the process of pattern decoration, silk-screen printing mainly plays a protective role, more times to apply photosensitive adhesive, in order to make a thicker screen template, so as to make good masking performance, etched pattern high definition.
6, screen version of the film under the action of light, produce photochemical reaction, make the light part of crosslinking into insoluble in water, and the light part is dissolved in water and exposed screen space, so as to coated with film screen lithography in accordance with the black and white positive plate pattern of leakage pattern.
