Nowadays, stainless steel passivation solution has been widely used in various industries in recent years. The principle is to use the oxidizing substances in the passivation solution to change the active metal ions on the metal surface into passivated state, which is not easy to be oxidized, so as to achieve the method of delaying the corrosion rate of metal. What's the difference between stainless steel pickling passivation paste and stainless steel pickling passivation solution? Here's an introduction:

Stainless steel pickling passivation solution:

It is suitable for all surface treated black spots, heat treated oxide skin, dirt and impurities on die casting surface, surface oxidation and stainless steel pickling and passivation requiring matte treatment. Stainless steel pickling and passivation liquid has double functions of pickling and passivation, which can not only make the stainless steel surface reach uniform silvery white rapidly, but also protect the stainless steel substrate and extend the corrosion and rust resistance of stainless steel while cleaning the stainless steel surface. The salt spray test can not rust for more than 500 hours, greatly extend the service life of stainless steel workpiece, and reduce Enterprise production cost.

The special advantages of stainless steel pickling passivation solution: while protecting the surface of stainless steel workpiece, it can make the product surface present uniform, consistent and beautiful silver white. It can be used repeatedly, with high production efficiency and low production cost. Compared with the outsourcing processing cost, it can be reduced by more than three times. The operation is simpler. It only needs to be soaked at normal temperature without special production site and equipment. Green environmental protection, no yellow smoke, and no excessive corrosion of stainless steel.

Stainless steel pickling passivation paste:

Main use: it is used to remove rust, oxide skin, yellow blue black welding spot and other dirt on the surface of various types of austenitic stainless steel parts, plates and their equipment. After cleaning, the metal surface becomes silvery white. Meanwhile, it passivates the surface and improves the corrosion resistance of stainless steel.

Outstanding features: transparent paste, strong ability to remove dirt, fast and convenient, especially suitable for local or overall treatment of large workpieces and equipment, not suitable for liquid immersion, superior to similar products in the market. Stainless steel pickling and passivation paste is a chemical agent to remove the weld spots and oxide skin of stainless steel after high-temperature processing. It is suitable for ferrite, austenite and other stainless steel. It can pickling and passivate stainless steel and improve its corrosion resistance, so that the surface of stainless steel is bright as new and the effect is superior. It is especially suitable for oxide scale which is difficult to clean or redesign the scheme for the special needs of customers. Features of pickling and passivation paste: pickling and passivation functions are combined into one, the process is simple and easy to use.

Stainless steel pickling passivation solution and stainless steel pickling passivation paste are two in one products, which are in the process of pickling passivation of stainless steel. It can selectively remove low potential nickel, iron and other impurities on the metal surface. The remaining major component of the surface is chromium. Due to the gray color of chromium, the passivation film formed by the reaction of chromium with passivating elements in passivation solution is silvery white. Therefore, the silvery white seen on the surface of the workpiece is actually the puzzle passivation film formed.
