First of all, I will introduce the history of stainless steel pickling passivation solution:
Stainless steel pickling passivation solution is a combination of advanced domestic and foreign technologies, using environmentally friendly inorganic acids and oxidants as the main agents, adding hydroxy acid compounds, high-efficiency corrosion inhibitors and inhibitors. It is a new type of high-tech material that is colorless, transparent and light-smelling. Stainless steel pickling passivation liquid is widely used to remove rust, weld spots, oil stains, black and yellow oxide scale produced during forming, assembly, welding and other processes, and at the same time comprehensively passivates stainless steel workpieces, greatly improving the corrosion resistance of stainless steel workpieces. . It truly achieves the two-in-one effect of pickling and passivation. The surface of stainless steel workpieces treated with stainless steel pickling passivation solution will produce a silver-white, dense and beautiful passivation film with strong stability and significantly improved corrosion resistance. The service life of the equipment is greatly extended and the added value of the product is increased accordingly.
Notes:
① Before pickling and passivating stainless steel workpieces, if there is dirt on the surface, it should be mechanically cleaned, oiled and degreased, otherwise it will affect the quality of pickling and passivation. Alkali, emulsifiers, organic solvents and steam can be used for oil and degreasing.
② In occasions with high passivation performance requirements, it is recommended that the chloride ion content in pure water should not exceed the standard. Excessive chloride ion content will destroy the passive film of stainless steel and is the root cause of pitting corrosion, crevice corrosion, stress corrosion cracking, etc.
③After soaking, be sure to clean the surface, otherwise the remaining liquid will have certain side effects on the surface of the workpiece.
④The maximum temperature should not exceed ℃. If stored for a long time, the maximum temperature should not exceed ℃. This product is highly acidic and corrosive. Please pay attention to safety. Pay attention to antifreeze in winter.
Let me introduce you to the simple operation:
① Normally, stainless steel pickling passivation can be operated indoors and outdoors by brushing, spraying and soaking for the best effect.
② Stainless steel small parts can be soaked in the original solution in a container. The soaking time in winter can be appropriately longer than in summer.
③ For larger equipment, in order to ensure the quality of cleaning and passivation while saving passivation materials, the pump circulation spray method can be used for treatment. <>
