Diethylenetriaminepentakis(methylphos-phonic acid) 

sol(((Phosphonomethyl)imino)bis(ethane-2,1-diylnitrilobis(methylene)))tetrakisphosphonic acid


Appearance: Red brown sticky liquid

Active component content: ≥50.0% 

Phosphorous acid(to PO3-3)content: ≤5.0%      

Calcium chelating value(to CaCo3)mg/g: ≥450

PH(1% aqueous solution): ≤2.0 

Density(20℃), g/cm3-: 1.35~1.45


Reddish brown viscous liquid, miscible with water, it shows excellent scale inhibition on calcium sulfate, calcium carbonate and barium especially in alkaline solution (the PH10-11), the product still has better scale inhibition on calcium carbonate. 

  1. In an alkaline solution (the PH10-11), there is still a good scale inhibition on calcium carbonate, than that of HEDP of ATMP can be increased by 2-3 times.      

  2. Have shows excellent scale inhibition ability on Barium sulfate.      

  3. Better inhibition effect than HEDP, ATMP.      

  4. Stabilizer for chlorine dioxide fungicide.


The excellent corrosion and scale inhibitors of circulating cooling water and boiler water, especially suitable for alkaline circulating cooling water as scale and corrosion inhibitor, can be used in oil field water and cooling water which contain barium carbonate and high sulfur barium, The stabilizer of chlorine fungicides dioxide. This product is used alone or in complex with the Pharmacy without adding a dispersant, a very small amount of dirt deposition is especially suitable for the Power Station in the closed loop of gray water and high hardness of alkali water.

Packaging and Storage: 25KG or 250KG plastic drum. Store in a cool room, storage period is one year
