Introduction to the passivation treatment of stainless steel
Pickling before passivation treatment can remove all contaminants and selectively remove small corrosion-resistant areas on the metal surface.
In order to achieve effective pickling and passivation, all organic dirt, grease, etc. must be removed before pickling and passivation.
Standard process:
Oil removal - water passing - activation, water passing, water passivation - water passing, neutralization passing water - water passing, pure water passing - drying
Operating process:
& Soak the original solution for a few minutes, take it out and wash it with clean water
Typical process:
Pre-treatment&;&;rinsing&;&;activation&;&;rinsing&;&;passivation&;&;rinsing& ;&;Neutralization&;&;Rinsing&;&;Drying
The purpose of activation is to expose the metal matrix on the stainless steel surface so that the chemical solution can be in direct contact with the metal surface to achieve a higher salt spray time. All workpieces that have been subjected to electrolytic polishing, chemical polishing, mechanical grinding and polishing with a clean surface, no oxide scale, and rust spots can be directly passivated
Application fields:
&This product is widely suitable for large batches, large output and convenience Soaked small and medium-sized stainless steel workpieces such as communication equipment components, stainless steel precision castings, small furniture, food machinery, digital electrical components, fasteners, tableware, doors and windows, medical equipment, hardware and electronics, agricultural tools, casings, pressure vessels and communication equipment Hardware parts, etc.
