NC-204(ZF151NC)(DTPMP)
Diethylene triamine penta (methylene phosphonic acid)
This product has been a scientific research project designated by National Science Commission to Nanjing University of Chemical Technology(85-94H-01-057). It was successfully completed by our General Manager, Professor Shen Hongli at that time. It was highly appraised by National Scientific Commission after double testing.
It shows excellent anti-scale effects in high-alkaline & high-hardness water. It has been paid special attention in US by the water treatment professionals. However, in domestic market, it is the first manufacturer who manufactured in massive production.
We sincerely hope to cooperate with all other water treatment professionals, especially to apply them in power plants and high-alkaline & high-hardness water.

(2) Properties:
The product is used for scaling inhibition and anti-corrosion in circulation cooling water systems,boilers and filling water in oil fields, it can also be used as a kind of stabilizer for peroxides.
It is soluble in water, and shows excellent scale inhibition effects to Calcium Sulphate scale, Calcium Carbonate scale & Barium Sulfate scale. The product shows excellent inhibition effect for calcium carbonate scales even under high pH as much as 10-11.
Compared with Organophosphonic Water Stabilizer, it has the following special characters: In alkaline solution (pH 10-11) it shows excellent inhibition effect for Calcium Carbonate scales. It is 1-2 times higher than HEDP & ATMP.
It shows excellent inhibition effect for Barium Sulfate scales.
It has much better scale inhibition effect than HEDP & ATMP.
It is a stabilizer for chlorinedioxide biocide.

(4)Use:
The product shows excellent corrosion inhibition effect for cooling water circulation system and boiler water,
especaily for calcium carbonate scale inhibitors even under high pH conditions. Also it has good scaling
inhibition effect for barium and calcium sulphate.
The product is used for scaling inhibition and anti-corrosion in circulation cooling water systems,boilers and
filling water in oil fields, it can also be used as a kind of stabilizer for peroxides.It could be used soly, and
you need not use any other dispersants with a small amount of scales left.
