DT-202Scale and corrosion inhibitor for mid-high hardness water


It is compounded by sulfosalt Copolymer, organic phosphorus acid, carboxylic acid copolymer and copper corrosion inhibitor.

It has a good chelating and dispersing effect to calcium carbonate and calcium phosphate etc.

It has a good corrosion inhibiting effect to carbon steel and copper.

Under higher PH value, it has good stability to zin salt. It is a high effective water treatment chemicals with double functionof corrosion and scale inhibition.

It used in opening type recirculating cooling water system, to prohibit heat exchanger scaling and corrosion. Scope of application is wide.In alkalescence recirculating cooling water system, it can form a layer of even resist film on the surface of metel. It is widely used in the recirculation cooling water system of petrify, chemical, electric power, metallurgy, central air-conditioning. Usually dosing amount is 10~20mg/L,no adjust PH value. If disposing by chlorine, pls control the residual quantity of Chlorine to 10~20mg/L.
