Frequently Asked Questions

What is the property of DTPMPA?
This product is non-toxic and easily soluble in acidic solution. It has excellent scale and corrosion inhibition effect and good temperature resistance. It can inhibit the formation of carbonate and sulfate scale. Its scale and corrosion inhibition performance is better than other organic phosphorus in alkaline environment and high temperature above 210 ℃.

What is DTPMPA used for?
DTPMPA is used as a scale and corrosion inhibitor for circulating cooling water and boiler water in water treatment, especially for alkaline circulating cooling water as a scale and corrosion inhibitor that does not adjust the pH, and can be used for oil field water injection and high barium carbonate content scale and corrosion inhibitor for cooling water and boiler water. when this product is used alone in the compound agent, there is no need to add dispersant, and the amount of dirt deposition is still small.
DTPMPA can also be used as a peroxide stabilizer, a chelating agent for textile printing and dyeing, a pigment dispersant, an oxygen delignification stabilizer, a trace element carrier in chemical fertilizers, and a concrete additive. In addition, it has also been widely used in papermaking, electroplating, metal pickling and cosmetics. It can also be used as a stabilizer for oxidative fungicides.
