3, Using method
DT-207uses the concentration of30mg/l,has good corrosion inhibition effect on the total hardness of100 mg / l,total alkalinity at100 mg / lof water such as the Changjiang River.Corrosion rate of carbon steel is less than0.075mm / a.
DT-207uses the concentration of30mg / l, has good corrosion inhibition effect on the total hardness of300 mg / l,total alkalinity at200 mg / l,chloride ion greater than300 mg / lof water, corrosion rate of carbon steel is less than0.075mm / a.
DT-207uses the concentration of60mg/l,the total hardness50 mg/l, has good corrosion inhibition effect ontotal alkalinity at50 mg / lfor example, the water quality of MinjiangRiver and other conditions of low hardness water.
DT-207can be compounded with other agents, can greatly reduce the use of concentration;
When using DT-207 alone, the bestuse concentration:40-60mg / l.
4, Package and Storage:DT-207packed with 25kg plastic drum or determined by the user.Storage for ten months.
5,Safety Protection:DT-207is acidic, operation with gloves and glasses, avoid contacting with eyes and skin ,once contacted,flush with water.
