What problems should be paid attention to when cleaning stainless steel color plates?
The following points should be paid attention to:
1. Although the vacuum PVD film has certain corrosion resistance, it is difficult to resist strong acid and alkali. Contact with corrosive substances. Therefore, in normal maintenance, stainless steel color plate manufacturers recommend that you try not to use strong acids and alkalis or cleaning agents with strong decontamination capabilities, such as toilet cleaners, paint removers, metal cleaners, etc., can be gently wiped with industrial alcohol and a soft cotton cloth . If the surface is dirty, it should also be treated with weak acid and weak base solvents. In addition, if exposed to harsh environments for a long time, or exposed to corrosive liquids for a long time, the PVD film is easy to fall off, such as swimming pools (containing fluorine), seawater (containing more salt), high temperature and high humidity (steam), etc.
2. Use anti-fingerprint varnish. More and more customers choose to spray a layer of transparent anti-fingerprint cleaning oil on stainless steel products coated with color PVD film. The effect is very obvious. There are no fingerprints on the hands, so it is easy to clean, and it can also add wear and corrosion resistance. But the disadvantage is that the color of the injected oil and the uninjected oil are inconsistent, the processing requirements are high, the cost is not low, the metal texture of the product is affected, and there are problems such as aging. Therefore, it must be carefully considered before use.
3. The following processing problems of stainless steel color steel plate. The PVD film has good adhesion to the substrate and is not easy to fall off. Products can be processed by simple machining such as shearing, folding, bending and cutting. However, welding has a great influence on PVD films, and instantaneous high temperature will cause the film to peel off and discolor. Therefore, stainless steel products that need to be welded should be colored, parts should be made before coloring, and PVD coating materials should not be used to process products.
Getting doesn't have to be expensive, time-consuming, or difficult. It all comes down to the right method and a architectural metal fabrication architectural metalwork in place.
Serving others for customers a better life with architectural metalwork for employees respect and opportunity.
Long gone are those days when architectural metal fabrication were used to architectural metal fabrication. Now new like architectural metal fabrication architectural metalwork have come up.
