What are the effects of sheet metal surface processing?

Sheet metal processing surface rendering effect:

Surface polishing is the use of mechanical or manual grinding materials to stainless steel sheet metal processing surface polishing method. Surface polishing and polished, mirror, mercerizing, sandblasting and other effects. Depending on the surface effect, the tools and methods used are not the same. Abrasive tools are abrasive emery cloth, sandpaper, magic wheel, polishing belt, grinding wheel and so on. Polishing, numerous abrasive particles equivalent to countless high hardness of the blade, the surface of stainless steel sheet metal machining, so as to achieve the purpose of leveling.

Pre-Polished and Pre-Polished Using a hard or hardened buffing wheel, the polished stainless steel sheet metal surface can be processed to remove coarse marks on the surface. Fine Polishing Soft pre-polished surface for further processing, remove the traces left by the pre-polishing, get bright mirror.

Mercerizing effect, is the use of brush polishing wheel mounted on the grinding and polishing machine, stainless steel sheet metal processing surface to be processed decorative silk thread brushed and satin finish effect of the process.

Sandblasting effect, the use of compressed air flow of sand or steel balls, glass balls and other abrasive spray stainless steel sheet metal processing surface, making it appear with a beautiful, slightly rough sandy surface.

Surface etching and etching, is the use of chemical corrosion of a mottled, vicissitudes of the decorative effect. Dalian sheet metal specific methods are as follows: First, the stainless steel sheet metal processing surface coated with a layer of asphalt, then the design of the decoration in the asphalt surface characterization, the corrosion of stainless steel sheet metal parts to be exposed. The following can be carried out corrosion, corrosion can be regarded as the size of the work, choose immersion chemical etching solution and spray solution corrosion. In general, small works choose immersion corrosion. Chemical acids are extremely corrosive and must be carefully protected against corrosion when doing so.

Surface mosaic process, has a long history, which includes inlay and embedded gold two kinds of craft. Here coloring introduced gold craft, also known as gold and silver wrong, it is the first surface of stainless steel sheet metal processing shades, embossed gold and silver or silver and other soft texture of stainless steel sheet metal processing materials, and then polished smooth. The effect is very delicate and colorful.

Surface forging, but also from the ancient forging process developed. It is the use of different shapes of the hammer in the stainless steel sheet metal processing surface forging, forming different shapes of dot-like texture, layers, very decorative.

Sheet metal commonly used surface treatment technology:

1. Plating: In the plating solution, charged ions are attached to the surface of the product under the action of an electric field to form a coating. Belongs to chemical changes.

2. Dusting: powder is polarized, under the action of the electric field force, even attached to the opposite polarity of the product surface. Belong to the physical changes.

3. Electrophoresis: electrophoretic coating In the role of the yin and yang poles, charged coating ions move to the product surface, the formation of coating deposition. Belongs to chemical changes.

4. Dip: The product is heated in a molten material, and the heated metal combines with the surrounding molten material to form a surface material of a certain thickness. Belong to the physical changes.

Other surface treatment methods such as paint, enamel, etc., are not commonly used for home appliances, are interested in learning.
