The Impact Of Stainless Steel Sheet Coating Of The Four Factors

  The impact of Stainless Steel Sheet coating of the four factors

  There are four factors that influence the coating of stainless steel:

  First, the inherent factors of Stainless Steel Sheet, we all know that the low nickel content of stainless steel, stainless steel passivation performance is low, so the stainless steel martensite content and chromium with nickel content on the stainless steel surface passivation performance is very Big.

  Second, the use of Stainless Steel Sheet in the environment, stainless steel passivation film in thermodynamics is a suppressed metastable structure, it plays a protective role in the environment in which the media. However, in any use in the environment, in the use of the process, the Stainless Steel Sheet should be regularly cleaned to remove the stainless steel surface attached to the harmful substances.

  Third, the surface cleanliness of Stainless Steel Sheet. For the stainless steel alloy, the surface of the stainless steel the more smooth the lower the roughness, then the surface of the stainless steel is more difficult to attach a foreign body, foreign matter is not easy to attach, then the corrosion of stainless steel surface also dropped to the lowest point, so stainless steel surface to The finished surface is used. In addition, the final passivation of the Stainless Steel Sheet should be carried out carefully so that the residual acid can promote the anodic reaction and protect the integrity of the film to ensure that the corrosion resistance of the surface of the Stainless Steel Sheet is enhanced.

  4, chloride ions, chloride ions on the Stainless Steel Sheet coating is a great harm, so we in the Stainless Steel Sheet on the surface of the passivation process to strictly control the passivation of chloride ion content, based on chloride ion on the stainless steel The dangers of the board. Many passivation of chemical materials on the chloride ion has a limited demand in the configuration of the passivation solution with water and cleaning water also has a strict water quality requirements, to ensure that passivation of finished products do not contain chloride ions.
