Stainless steel plate is made of stainless steel, will not rust, but also very strong, is a common steel plate, of course, in some special projects may be bleaching treatment of it. But how does this bleaching process work?
1. What is bleaching treatment? Refers to the stainless steel plate in the processing process, will be rolled, tied, welding or artificial surface fire heating treatment, resulting in black oxide skin removal, the traditional stainless steel surface color whitening treatment is generally used hydrofluoric acid and nitric acid for strong corrosion method removal, but this method costs a lot, but also pollute the environment.
2. At present, there are sandblasting and chemical methods for the surface oxidation treatment of stainless steel plates. Sandblasting method: Mainly using the method of spraying microglass beads to remove the black oxide on the surface. Chemical method: The use of a pollution-free pickling passivation paste and room temperature non-toxic with inorganic additives cleaning solution for leaching, so as to achieve the purpose of stainless steel bleaching treatment, basically looks a dull color after treatment, this method is more suitable for large, complex products.
Stainless steel plate in some processes may produce a certain amount of oxide, this time we can be carried out by bleaching treatment, according to sandblasting and chemical treatment is a more appropriate method, we can try it.
