APPLICATION

• It has a good chelation, low limit inhibition and lattice distortion. Can prevent the formation of water-fouling scale salts, in particular for calcium carbonate scale. ATMP is stable in water, hardly hydrolyze. It has good inhibition effect when the concentration is high in water. It is widely used in circulating cooling water, oil field injection water system for thermal power plants, oil refineries. Can play a role in reducing mental equipments and pipe corrosion and scaling. It is used as metal ion chelating agent in textile printing and dyeing industries, also used as metal surface treatment agent.

• This product is usually used together with organophosphoric acid, copolymer and zinc salt to built full organic alkaline water treatment agent, it can be used in many different circulating cool water systems. The dosage of 1-20mg/L is recommended, while the dosage of 20-60mg/L is preferred as corrosion inhibitor.
