The necessity of high salt spray passivation and rust prevention for door hinges. Stainless steel surface cleaning, pickling and passivation not only maximize the corrosion resistance, but also prevent product contamination and achieve beautiful appearance. According to the "Steel Pressure Vessels" regulations, the surface of containers made of stainless steel and composite steel plates with anti-corrosion requirements should be pickled and passivated. This regulation is for pressure vessels used in the petrochemical industry. Because these equipment are used in situations where they are in direct contact with corrosive media, pickling and passivation are necessary to ensure corrosion resistance. For other industrial sectors, if it is not for anti-corrosion purposes and is only based on cleanliness and aesthetic requirements, pickling and passivation are not required for stainless steel materials. However, the welds of stainless steel equipment also need to be pickled and passivated. For nuclear engineering, certain chemical equipment and other applications with strict requirements, in addition to pickling and passivation, high-purity media must be used for final fine cleaning or finishing treatments such as mechanical, chemical and electrolytic polishing
Precautions
Time and temperature are directly related to the pickling effect.
If there is oil stain on the surface of stainless steel, stainless steel cleaning agent, degreasing agent, etc. can be used to remove the oil.
It is recommended to wear protective glasses, rubber gloves and other protective equipment for operation.
Store in a cool place separate from other items.
This product is acidic. It is strictly prohibited to splash into the body during construction. If it is accidentally touched, please wash it with plenty of flowing water
Product Introduction
Stainless steel pickling passivation liquid is used to remove various types of Austrian Rust, oxide scale, yellow, blue and black weld spots and other contaminants on the surface of stainless steel parts, plates and equipment after welding
After being treated with stainless steel pickling solution, the surface of stainless steel becomes silvery white and passivated at the same time Surface, improve the corrosion resistance of stainless steel
Flexible operation, simple operation, easy to use, just apply or spray
Appearance characteristics After treatment, the workpiece is uniform, silvery white and bright, and has strong decorative properties.
Absolutely environmentally friendly and does not contain harmful ingredients such as heavy metals, and its value is acidic.
