Phosphonate Scale and Corrosion Inhibitor
Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA)
CAS.15827-60-8
ApplicationThe DTPMPA is an acid soluble scale and corrosion inhibitor with superb inhibition effect and temperature resistance. It prevents the formation of carbonate and sulfate scales. In alkaline environment and high temperature (210 ℃ above), it shows better performance than other organic phosphorus.
The DTPMPA is used in circulating cooling water and boiler water systems, especially for water under alkaline conditions. It is also applicable to high barium carbonate water conditions. Generally, when it is used as anti-scale agent, a concentration of 1-30mg / L is recommended; while as cleaning agent, 1000-2000mg / L is preferred. It is usually used with polycarboxylic acid scale dispersants.
