Cleaning Precoating Agent LD-QX001

Cleaning prefilm is mainly made of phosphonate and active compound. By complexing with calcium and magnesium ions in cooling water, a deposition film is formed on the metal surface. 

Product property:

Cleaning prefilm is mainly made of phosphonate and active compound. By complexing with calcium and magnesium ions in cooling water, a deposition film is formed on the metal surface. The film has a large resistance and insulates metals from corrosive media in water, thereby inhibiting corrosion. The product has the characteristics of fast film forming, fine and uniform film quality, good chemical stability and low corrosion rate.

Specification:

Range of application:

In chemical industry, chemical fertilizer, oil refining, oil field, metallurgy, power generation and other industrial water circulation cooling water system, the new equipment of circulating cooling water after starting up or the system overhauling the heat exchange equipment and pipeline prefilm, so that the metal surface form a protective film to prevent the operation of carbon steel, Corrosion of copper alloy, stainless steel and other materials.

Usage method:

The concentration of high-efficiency pre-membrane agent is 300-500 mg / L directly at the entrance of pool pump. The prefilm time is 48-72 hours in cold state and 24-48 hours in hot state. Total inorganic phosphorus is less than 10 mg / L (PO₄³).
