Performance characteristics
1. This product is used for pickling and passivation of welded joints and surfaces of large stainless steel workpieces, to remove the oxide skin produced after welding and high temperature processing, to make them bright and shiny, and to form a layer on the treated surface. The oxide film with chromium and nickel as the main substances will not produce secondary oxygen corrosion and achieve the purpose of passivation, thereby improving the surface anti-corrosion quality of stainless steel products and prolonging the service life of equipment.
2. This product performs degreasing, pickling and passivation at the same time and completes it in one step, which changes the traditional degreasing, pickling and passivation processes, with simple operation, convenient construction and low cost.
3. The use of this product does not require special equipment and venues, heating equipment and power supplies, and skilled operators, saving labor, time and energy.
4. This product is a stable ointment, which is easy to transport and can be stored for a long time. It is extremely convenient to take it at any time. When there is a small amount of precipitation, it can be used by stirring evenly without affecting the use effect.
Scope of application
Widely used in chemical, pharmaceutical, papermaking, food, machinery manufacturing, construction and other stainless steel equipment, pressure vessels, surface treatment of engineering components.
