Compound dedicated corrosion inhibition,Cleaning and Pretreatment Filming Agent

DT-207 non-phosphorus corrosion inhibitor



DT-207 has no phosphorus, in phosphorus discharge high demanding areas, can greatly reduce the cost of sewage treatment. As without phosphate, it reduce the propagation of microorganisms in the circulating water system and reduce the dosage of bactericide and sludge stripper.

Using method

1. DT-207 uses the concentration of 30mg/l, has good corrosion inhibition effect on the total hardness of 100 mg / l, total alkalinity at 100 mg / l of water such as the Changjiang River.Corrosion rate of carbon steel is less than 0.075mm / a.

2. DT-207 uses the concentration of 30mg / l, has good corrosion inhibition effect on the total hardness of 300 mg / l, total alkalinity at 200 mg / l, chloride ion greater than 300 mg / l of water, corrosion rate of carbon steel is less than 0.075mm / a.

3. DT-207 uses the concentration of 60mg/l, the total hardness 50 mg/l, has good corrosion inhibition effect on total alkalinity at 50 mg / l for example, the water quality of Minjiang River and other conditions of low hardness water.

4. DT-207 can be compounded with other agents, can greatly reduce the use of concentration;

5. When using DT-207 alone, the best  use concentration: 40-60mg / l.
