GT-619B Scale and Corrosion Inhibitor


GT-619B is composed of organophosphoric acid, polycarboxylic acid, sulfosalt copolym-ers, copper corrosion inhibitor, special surfactant, etc. The organophosphine acid forms protection membrane and brings corrosion inhibition on metal surface. GT-619B has good chelation and lattice distortion effect on calcium carbonate, calcium sulfate and calcium phosphate. Through rational prescription, GT-619B has good synergistic effect, with high corrosion inhibition ratio, high temperature tolerance, high scale inhibition ratio and not easy to degradation.
