XT-619B is composed of organic phosphoric acid, polycarboxylic acid, sulfosalt copolymers, copper corrosion inhibitor, special surfactant, etc. The organic phosphonate forms a protection membrane on metal surface to inhibit the corrosion. XT-619B has good chelation and lattice distortion effect to calcium carbonate, calcium sulfate and calcium phosphate. Through rational prescription, XT-619B give full play to the synergistic effect with the advantages of high corrosion inhibition ratio, high temperature resistance, strong scale inhibition ability and it is hard to decompose.
