Stainless steel pickling and passivation paste

Features:

1. This product is used for pickling and passivation of stainless steel welded joints and surface removal of welding, high-temperature processing of oxide of silver bright light, and treated the surface layer of chromium the main substance of the oxide film, will not produce secondary oxygen erosion, reaching the passivation purpose, thereby enhancing the quality of surface corrosion of stainless steel products, prolong equipment life. Rust removal and passivation effect than similar foreign products (AVESTA) reached the international advanced level.

2：Pickling and passivation simultaneously in one step, has changed the traditional pickling and passivation process, simple operation, convenient construction, low cost.

3 so that the FDA does not require specialized equipment and facilities, no heating equipment and power, does not require skilled operation workers, labor, time-saving, energy saving.

4：This product is a stable ointment, it does not decompose, no precipitation, the transportation is convenient and can be stored for a long, used with the check, extremely convenient.

Scope of application

Widely used in chemical, pharmaceutical, paper, food, aerospace, nuclear industry, construction and other stainless steel equipment, pressure vessels, the surface treatment of the engineering components.

Use

4.1 with a plastic rod or stainless steel rod Stir the product.

4.2 smear a coating thickness of 1-3 mm.

4.3 to ensure sufficient reaction time (about 20 minutes). Time, temperature, and the pickling effect is proportional to the construction of an appropriate extension of time below 0 ℃.

4.4 stainless steel wire brush, plastic brush and other non-carbon steel tools, remove loose residue on the surface.

4.5 wash with water to clean the surface to be processed.

4.6 If the surface of stainless steel oil can be used acetone and other solvents to remove
