Important Application in Water Treatment

YIGYOOLY Hydrolyzed Polymaleic Anhydride disperses solid particles in water to prevent their deposition and scaling. It has the following benefits:

YIGYOOLY Hydrolyzed Polymaleic Anhydride has good dispersing effect: It can disperse solid particles in water to prevent their deposition and scaling, thereby maintaining the cleanliness and transparency of the water.

YIGYOOLY Hydrolysed Polymaleic Anhydride has good scale inhibition effect: It can form complexes with calcium and magnesium ions in water to prevent their deposition and scaling, thereby reducing the maintenance and cleaning frequency of water treatment equipment.

YIGYOOLY Hydrolyzed Polymaleic Anhydride has good corrosion inhibition effect: It can form complexes with metal ions to prevent oxidation and corrosion of metal ions, thereby extending the service life of water treatment equipment.

YIGYOOLY Hydrolysed Polymaleic Anhydride has good stability: HPMA has good thermal and chemical stability, and can maintain its dispersibility and scale inhibition performance under different water treatment conditions.

Application

YIGYOOLY Hydrolyzed Polymaleic Anhydride has good scale inhibition (98%) and scale stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.

HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for circulating cool water system, low-pressure boilers, oilfield fill water and crude oil dewatering.
