Performance and Applications
T-225 is a copolymer of acrylic acid and hydroxypropyl acrylate. It has a good inhibitory effect on the formation and deposition of calcium carbonate, calcium sulfate, especially calcium phosphate scale, and also has a good dispersion performance on ferric oxide, sludge, clay and oil scale. It can be used under high pH conditions; it has good miscibility with organophosphonates, BTA, etc., and has a special effect on inhibiting the deposition of zinc salt and the precipitation of calcium phosphate scale.
T-225 has good scale inhibition and dispersion performance at high temperature and alkaline conditions, and is suitable for use in circulating cooling water under alkaline conditions and with more phosphate.
T-225 is mainly used as a scale inhibitor and dispersant for various circulating cooling water (especially circulating cooling water with high turbidity and dust pollution in the use environment).
