Introduction: Amino Trimethylene Phosphonic Acid, also known as aminotrimethylenephosphonic acid (ATMP), has good chelating, low-limit inhibition and lattice distortion effects. It can prevent the formation of scaling salts in water, especially the formation of calcium carbonate scale. Amino trimethylene phosphonic acid is chemically stable in water and not easily hydrolyzed. When the concentration in water is high, it has good corrosion inhibition effect.

 

Application: Amino Trimethylene Phosphonic Acid is used in thermal power plants, circulating cooling water in oil refineries, and oilfield reinjection water systems. Amino trimethylene phosphonic acid can reduce corrosion and scaling of metal equipment or pipelines. ATMP is used as a metal ion chelating agent in textile printing and dyeing industries, and can also be used as a metal surface treatment agent. The solid is a crystalline powder, easily soluble in water, easy to absorb moisture, easy to transport and use, especially suitable for cold regions in winter. Due to the high purity of aminotrimethylene phosphonic acid ATMP, it can be used as a metal chelating agent and metal surface treatment agent in the textile printing and dyeing industry.
