What are the stainless steel sheet surface treatment processes?

We often see the surface treatment of stainless steel: wire-drawing, mirror, sandblasting, titanium plating, etching, anti-fingerprint and so on, in the interior decoration has many wonderful applications:

1. Wiredrawing plate: usually in the stainless steel surface mechanical friction method of processing after the surface state for straight lines (also known as frosting), including wiredrawing, and lines, ripples.

Processing quality standard: uniform grain thickness and depth, the grain on each side of the product according to the design and construction requirements, natural and beautiful, the bending position of the product is allowed to have a slight does not affect the appearance of the disorderly grain.

2. Mirror board: such as super mirror gold stainless steel sheet, a bright surface effect obtained by rough grinding, medium grinding and fine grinding of high quality whetstone, diamond grinding paste and sandpaper of different grades with polishing and grinding equipment.

Processing quality standard:

No sand or hemp (orange peel).

The surface should be flat, and there should not be any concave, protrusion or undulating wave surface (distorting mirror).

No blank surface residue, sand holes, scars, impurities, bruises, scratches.

The brightness reaches 8K, and the brightness of polished mirror exceeds 8K.

3. Sandblasting: use compressed air as the power to form high-speed jet beam to spray materials (quartz sand, emery sand) to the surface of the workpiece to be processed at a high speed, so that the board surface presents a fine bead sand surface, forming a unique decorative effect

4. Etching: Etching Stainless Steel Sheets, stainless steel sheet surface chemical etching pattern text technology principle, is a special corrosion layer will not be etched on the surface of part of the cover, shielding acid, so that acid can only touch the surface of the part to be etched, from the surface to achieve the purpose of etching patterns and words.

5. Anti-fingerprint: stainless steel resistant fingerprint plate is a composite coating plate obtained after the fingerprint processing on the surface of stainless steel, the coating method is mainly used by roller coating or spraying.

6. Titanium plating: also known as stainless steel titanium/zirconium plating film, is in a vacuum container, the formation of titanium/zirconium compound ion film layer on the surface of stainless steel, film layer can be in the outdoor environment for a long time does not fade.

Principle of titanium plating: in high temperature, vacuum titanium gold furnace, titanium, zirconium metal, use the glow discharge of inert gas to ionize the metal or alloy vapor, the ions are accelerated by the electric field deposition with negative charge on the stainless steel plate, so as to form colorful metal film.

Water plating: it is the use of electrolysis to make metal or alloy deposition on the surface of the workpiece, in order to form uniform, dense, good adhesion of the metal layer process, is called water plating; A simple understanding is a change or combination of physics and chemistry; Water plating is generally used for black titanium plating, electroplating black relatively gray, water plating black will be more bright.
