Affect The Four Factors Of Stainless Steel Plate Coating
Jul 14, 2017

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

First, the inherent factors of stainless steel plate, 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 and nickel content on the surface of the stainless steel plate passivation performance is very Big.

Second, the use of stainless steel plate in the medium, 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 course of the use of regular stainless steel plate should be cleaned to remove the surface of stainless steel attached to the harmful substances.

Third, the surface cleanliness of stainless steel plate. For stainless steel, 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 will drop to the lowest point, so stainless steel surface to Using a finished surface. In addition, the final passivation of the stainless steel plate should be carried out carefully so that the residual acid can promote the anode reaction and protect the integrity of the film to ensure that the corrosion resistance of the surface of the stainless steel plate is enhanced.

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