English name

Acrylic acid-arcylate copolymer

Molecular formula

Performance

Properties of dispersibility, scale inhibition and corrosion inhibition, good dispersibility to suspended solids such as silt and organic matter.

Inhibition and dispersibility to calcium orthophosphate and ferric oxide sludge, and dispersibility to clay and oil dirt.

Certain corrosion inhibition, corrosion rate to carbon steel of 0.33mil per year under certain condition.

Application

Used as scale inhibitor and dispersant in an open recycling cooling system, especially for water in windy and sandy North and with high concentration of suspended solids and organics.

Used in low pressure boiler and steamer instead of hydrolyzed polymaleic anhydride

Used as scale inhibitor and dispersant in an open recycling cooling system instead of T-255 of Kurita (Japan) ; Used alone or in combination with other chemicals in cooling water and boiler water system.

Used as an inhibitor in oil field water system.

Other water recycling system.
