Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer

【CAS】40623-75-4

Chemical formula：[C ₃ H ₄ O ₂] n [C ₇ H ₁₈ NO₄ S] m

Structural formula:

This product has the following features: better phosphate scale inhibition than some acid copolymer scale inhibitor existing in the market. When built with zinc salt at 10% odds, it can prevent precipitation generation of zinc salt in solution of high pH and high alkaline.

This product can disperse iron, zinc, dioxides and calcium phosphate well. Due to the sulfonic acid group included in this copolymer, AA/AMPS can increase the solubility of carbonate, thus was used as precipitation inhibitor for the iron oxide, zinc oxide and sediment in the leaching cool water in iron and steel company and as scale and corrosion inhibitor built with organic phosphate and zinc in the circulating cool water with high alkalinity.

Quality index:

Appearance: light yellow or colorless transparent liquid.

AA/AMPS can be used as scale inhibitor and dispersant for pre-treatment filming and ferric oxide at the dosage of 80-100mg/L. Regular dosage is 10-30mg/L, when used together with organic phosphonic acid and zinc salt, the suitable pH value is 7.0~9.5.

Package: in 25kg or 200kg net plastic drum.
