Performance characteristics:
◎This product is composed of polyepoxysuccinic acid, multicomponent non-phosphorous copolymer and corrosion inhibitor. It is a non-phosphorus corrosion inhibitor and scale inhibitor for circulating cooling water system of power plant;
◎It has strong complexation and solubilization effect on carbonate scale, prevents scale from precipitating on the surface of heat exchanger, and its scale inhibition effect is effective in the range of PH value 7.0-9.0;
◎Has the lattice distortion and the low limit inhibition function, has the very good inhibitive scale dispersing performance to the calcium carbonate scale;
◎It can quickly form adsorption film on the surface of copper, stainless steel and titanium alloy, and prevent the heat exchanger from being corroded by dissolved oxygen;
◎Has the high temperature resistance, the oxidation resistance and the good compatibility;
◎Compound medicament, the operation is simple;
◎It can meet the requirements of power standard without phosphorus and cause no environmental pollution.
