If you want your stainless steel workpiece to be clean and bright and not rust for a long time, you can try - stainless steel pickling passivation solution. People often ask:
&What is the main substance (component) of the passivation film? How thick is it? ?Will it change the material composition? Will it affect the performance of the workpiece (electrical conductivity, mechanical properties&b;&b;)?
&. Strictly speaking, the passivation film does not form any new substances and its main components Restore the original composition of stainless steel. Through the microchemical reaction of passivation, we only change the chemically active properties of the metal on the surface of the material, changing the originally chemically active metal surface into a chemically inert (passive) metal surface. There is no new substance formed on the surface and it is still the composition of the original stainless steel (it is impossible to change the composition of the material through passivation)
The industry's response: the surface is a combination of chromium oxide and nickel oxide (there is no way to deal with it) Certification (for customers who still want to ask about the first item)
Thickness of the passivation film: There are reports in the industry that there are nanometer thicknesses and micron thicknesses, but there is no way to prove it. Our unified answer is: the thickness is about microns ( a silk). Because we have no way to prove that a silk screen is more beneficial from the perspective of customers worried that the passivation film will be damaged.
Product introduction:
&; Stainless steel pickling passivation solutions are all mild and weakly acidic passivation solutions that do not change the original size and color of the workpiece; they are all natural passivation solutions soaked at room temperature. Passivation mechanism: During the immersion process, the product forms a dense passivation film on the surface of the product through the microchemical reaction between the passivation liquid and the product surface, which effectively improves the product's anti-rust and salt spray resistance.
