Diethylenetriamine pentamethylenephosphonic acid (sodium) DTPMPA
Classification:
Product Introduction
Performance and Usage
Non-toxic, soluble in acidic solution, good scale and corrosion inhibition effect and good temperature resistance, can inhibit the formation of carbonate and sulfate scale, in alkaline environment and high temperature (above 210 ℃) scale and corrosion inhibition performance is better than other organic phosphine. It is used as scale and corrosion inhibitor for circulating cooling water and boiler water in water treatment. It is especially suitable for scale and corrosion inhibitor without adjusting pH in alkaline circulating cooling water, and can be used for scale and corrosion inhibitor for oilfield water injection and cooling water and boiler water containing high barium carbonate. This product is used alone in the compound agent without adding dispersant, and the amount of dirt deposition is still very small.
Can also be used as a peroxide stabilizer (especially under high temperature conditions, hydrogen peroxide stability effect is good), textile printing and dyeing chelating agent, pigment dispersant, oxygen delignification stabilizer, fertilizer trace elements carrier, concrete additives. In addition, it has been widely used in papermaking, electroplating, metal pickling and cosmetics. It can also be used as a stabilizer for oxidizing fungicides.

Method of use
As a scale inhibitor generally use the concentration of 1~30mg/L, as a cleaning agent generally use the concentration of 1000~2000mg/L; usually with polycarboxylic acid type scale inhibitor dispersant. When used in other industries, the dosage should be determined according to the test.
Packaging and storage
Plastic drum packaging, 25kg per barrel or according to user needs to determine. Store in a cool indoor place for 12 months.
Safety and protection
It is neutral, pay attention to labor protection during operation, avoid contact with skin, eyes, etc., and rinse with plenty of water immediately after contact.
