Information
The stainless steel surface treatment processes we commonly see in the market include wire drawing, mirror surface, sandblasting, titanium plating, etching, anti-fingerprints, etc. The surface treatment process of stainless steel screens is created by different colors and styles. What kind of Different colors are used for the effect, so what are the processes for surface treatment of stainless steel screens?

1. The surface treatment process of stainless steel screen includes brown, black titanium, red bronze, etc., which belong to the more classic color series. Different screen patterns and styles have different production processes: wire drawing, mirror surface, sandblasting, titanium plating, etching, anti-fingerprint, etc. There are many wonderful applications in interior decoration:


1. Wire drawing (frosted): usually processed by the method of mechanical friction on the surface of stainless steel to obtain straight lines on the surface (also called frosted), including wire drawing, pattern, and ripple.

2. Mirror surface: A bright surface effect obtained by rough grinding, middle grinding and fine grinding using high-quality oilstone, diamond grinding paste and different grades of sandpaper using polishing and grinding equipment.

3. No fingerprints: The stainless steel anti-fingerprint plate is a composite coating plate obtained after anti-fingerprint treatment on the surface of stainless steel. The coating method is mainly roller coating.

2. The top surface of the mirror surface of the stainless steel screen:

1. Processing quality standard: the thickness of the texture is consistent and uniform. The texture on each side of the product is natural and beautiful according to the design and construction requirements. The product's bend is allowed to have a slight messy texture that does not affect the appearance. The surface should be flat, and there should be no depressions, protrusions or undulating waves. There are no residues, sand holes, scars, impurity spots, bruises and scratches on the rough surface. There is no sand pattern and hemp pattern (orange peel pattern).
2. The brightness reaches 8K, and the brightness of the polished mirror exceeds 8K. Definition of terms: "8" in 8K refers to the proportion of alloy components, "K" refers to the level of reflectivity after polishing (K level is mirror reflection level), 8K mirror surface is also chrome-nickel alloy Mirror grade reflected by steel.


3. The surface treatment process of stainless steel screen includes the following steps:

1. Cleaning: clean the surface of the stainless steel workpiece to remove grease on the surface of the workpiece;
2. Sandblasting: sandblasting the surface of the workpiece after cleaning; using compressed air as the power to form a high-speed jet beam to spray the blasting material (quartz sand, emery) onto the surface of the workpiece to be treated at a high speed, so that the surface of the board will show fine beads Granular sand surface, forming a unique decorative effect

3. Spraying: spray one or two layers of glue evenly on the surface of the stainless steel workpiece;

4. Sintering: Put the stainless steel workpiece sprayed with glue into the oven for sintering to form a stainless steel non-stick layer;

5. Coloring: anodize the stainless steel workpiece, and then color it;

6. Coating: Apply anti-fingerprint coating on the surface of stainless steel workpiece after coloring to form anti-fingerprint film;

7. Drying: Dry the stainless steel workpiece coated with anti-fingerprint coating.

8. Etching: The process principle of chemically etched pattern text on the surface of stainless steel is to cover the unetched part of the surface with a special anti-corrosion layer to shield the acid liquid, so that the acid liquid can only touch the surface of the part to be etched, and reach from the surface. The purpose of etching patterns and text.

4. Titanium plating: It is also called stainless steel titanium/zirconium coating. In a vacuum container, an ionic film layer of titanium/zirconium compound is formed on the surface of stainless steel. The film layer can not fade for many years in an outdoor environment.

5. The principle of titanium plating: in a high temperature, vacuum titanium gold furnace, titanium and zirconium metals are ionized by glow discharge of inert gas to ionize the metal or alloy vapor, and the ions are accelerated by the electric field to deposit negatively charged stainless steel plates, thereby Form a metal film with rich and gorgeous color.


The above is the whole content of the stainless steel surface treatment process. I hope everyone can have a deeper understanding of the surface treatment process of stainless steel through this article.
