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.
