Polycarboxylate Scale Inhibitor and Dispersant

Sodium Polyacrylate Modified Sodium Polyacrylate 2000 Carboxylate-Sulfonate-Nonion Terpolymer AA/AMPS AA/ HPA PESA PASP PAA PCA HPMA MA/AA

Acrylic Acid-2-Hydroxypropyl Acrylate Copolymer (AA/ HPA)

CAS. 55719-33-0

Application

The AA / HPA has good inhibition effect on the formation and deposition of calcium carbonate, calcium sulfate, and especially the calcium phosphate scale. It has good dispersion effect on iron trioxide, sludge, clay and grease. It is especially effective in inhibiting zinc salt deposition and calcium phosphate precipitation.

The AA / HPA scale inhibitor is applicable to alkaline and phosphate-rich cooling water conditions. It serves a variety of circulating cooling water, especially the high-turbidity and dust contaminated one. The normal dosage is10-30mg/L. It can be mixed with organic phosphine for a full organic (alkaline) formula.
