● (1) Molecular Weight & Chemical Structure: N(CH2PO3H2)3 299.0 ●(2) Properties: This product contains very low toxicity or may be considered as non-toxic. It has good thermal stability, which shows excellent scale inhibition property under the temperature of 200℃, especially for carbonate scales. At the dosage of 40ppm,the product still show high anticorrosion property. ●(3) Specification: Kind Domestic Products export subsidy Appearance Clear water white to pale yellow aqueous solution Active content ≥50% 48.0~52.0% Phosphorous acid(as H3PO3) ≤5.0% ≤4.5% Phosphoric acid(as PO4) ≤1.0% iron＜35ppm Chloride (as Cl-) ≤3.5% ≤5.0% pH(1% water solution) 1.5~2.5 ＜2 Density(20℃ g/cm3) ≥1.28 ≥1.28 Ca chelate value mgCaCO3/ g ＞300 ＞350 Color (APHA) 45 After detected with 31P—NMP it is concluded that this NC-202 has the content of more than 96%. This is in accordance with the criterions -DEQUEST2000 set by American Monsanto Chemical Company.
This product is used in cooling water circulation system ,water pipes and boilers to prevent them from scaling. It an also be used as scale inhibitor for the petroleum pipeline where high hardness, high mineralization and poor water quality will be expect
