DTPMPA Diethylenetriamine pentamethylene phosphonic acid

Performance and Use:

DTPMPA is non-toxic, easy to dissolve in acidic solution, has excellent scale and corrosion inhibition effect and good temperature resistance, can inhibit the formation of carbonate and sulfate scales, and has better scale and corrosion inhibition performance than other organic phosphorus under alkaline environment and high temperature (above 210 C).It is used as scale and corrosion inhibitor for circulating cooling water and boiler water in water treatment, especially for alkaline circulating cooling water as scale and corrosion inhibitor without adjusting pH, and for oilfield water injection and cooling water and boiler water with high barium carbonate content. The product is used alone in the compound agent without adding dispersant, and the amount of fouling deposit is still small.

DTPMPA can also be used as a peroxide stabilizer, a chelating agent for textile printing and dyeing, a dispersing agent for pigments, an oxygen delignification stabilizer, a carrier of trace elements in chemical fertilizers, and a concrete additive.In addition, it has been widely used in papermaking, electroplating, metal pickling and cosmetics.It can also be used as a stabilizer of oxidative fungicides.

Quality indicators:


Usage method:

DTPMPA is generally used as scale inhibitor with a concentration of 1-30 mg/L and as a detergent with a general concentration of 1000-2000 mg/L; it is usually used with polycarboxylic acid type scale inhibitor dispersant.When used in other industries, the dosage should be determined according to the experiment.

Packaging and storage:

DTPMPA is packaged in plastic drums, 25Kg or 30Kg per drum, which can also be determined according to user needs.Store in a cool indoor place for 12 months.

Safety and protection:

DTPMPA is acidic, pay attention to labor protection during operation, should avoid contact with eyes and skin, once splashed on the body, should be immediately rinsed with a large amount of water.
