Diethylene Triamine Penta (Methylene Phosphonic Acid) (for water treatment)

Technical Data Sheet

Performance and Uses
DTPMPA is non-toxic and easily soluble in acidic solutions. It has excellent scale and corrosion inhibition effects and good temperature resistance. It can inhibit the formation of carbonate and sulfate scales. In alkaline environments and high temperatures (above 210°C), its scale and corrosion inhibition performance is better than other organic phosphites. DTPMPA is used as a scale and corrosion inhibitor for circulating cooling water and boiler water in water treatment. It is particularly suitable for alkaline circulating cooling water as a scale and corrosion inhibitor without pH adjustment. It can also be used as a scale and corrosion inhibitor for oil field injection water and cooling water and boiler water containing high barium carbonate. When this product is used alone in compound reagents, there is no need to add dispersants, and the amount of dirt deposition is still very small.

DTPMPA can also be used as a peroxide stabilizer (especially hydrogen peroxide has a good stabilization effect under high temperature conditions), a chelating agent for textile printing and dyeing, a dispersant for pigments, an oxygen delignification stabilizer, a trace element carrier in 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 oxidizing fungicides.

Usage
DTPMPA is generally used at a concentration of 1～30mg/L as a scale inhibitor, and 1000～2000mg/L as a cleaning agent; it is usually used in combination with polycarboxylic acid scale inhibitor dispersant. When used in other industries, the dosage should be determined based on the test.

Packaging and storage
DTPMPA is packaged in plastic barrels, 30kg per barrel or determined according to user needs. Store in a cool place indoors, with a storage period of twelve months.

Safety protection
DTPMPA is acidic, pay attention to labor protection during operation, avoid contact with skin, eyes, etc., and rinse with plenty of water after contact.
