Comprehensive understanding of diethylenetriamine pentamethylphosphonic acid DTPMPA

DTPMPA is a non-toxic compound that plays an important role in water treatment.
DTPMPA, also known as diethylenetriamine pentamethylene phosphonic acid, is easily soluble in acidic solutions and has excellent scale and corrosion inhibition effects. It also has excellent taperature resistance and can inhibit the formation of carbonate and sulfate scales. In alkaline environments and high taperatures, DTPMPA has superior scale and corrosion inhibition performance compared to other organic compounds. Therefore, DTPMPA is widely used in the field of water treatment as a scale and corrosion inhibitor for circulating cooling water and boiler water, especially suitable for alkaline circulating cooling water as a pH free scale and corrosion inhibitor. It can also be used as a scale and corrosion inhibitor for oilfield water injection, cooling water, and boiler water with high barium carbonate content; When used alone in compound formulations, there is no need to add dispersants, and the amount of dirt deposition is still very small. In addition, DTPMPA is also used as a peroxide stabilizer, chelating agent for textile printing and dyeing, dispersant for pigments, oxygen delignification stabilizer, trace elaent carrier in fertilizers, concrete additive, etc. In the fields of papermaking, electroplating, metal pickling, and cosmetics, DTPMPA also plays an important role and can be used as a stabilizer for oxidizing fungicides.
DTPMPA is generally used as a scale inhibitor with a concentration of 1-30mg/L, and as a cleaning agent with a concentration of 1000-2000mg/L; Usually used in combination with polycarboxylate type scale inhibitors and dispersants. When used in other industries, the dosage should be determined based on experiments. DTPMPA is packaged in plastic drums, with each drum weighing 30kg or depending on user needs. Store in a cool indoor place for a storage period of twelve months.
DTPMPA is acidic, so pay attention to labor protection during operation and avoid contact with skin, eyes, etc. After contact, rinse with plenty of water.
