A, performance
Corrosion inhibitor (edta methylene phosphonate sodium EDTMPS) is nitrogen organic phosphonate multiple, belong to the cathode type corrosion inhibitor, and inorganic phosphate together than high rate of corrosion inhibitor 3 ~ 5 times. Can and water immiscible, non-toxic no pollution, chemical stability and resistant temperature well, and in 200 ℃ still have good scale inhibition effect. EDTMPS in aqueous solution that can be dissociated into eight are negative ion, and therefore can be more than with metal ions chelation, form multiple single structure macromolecular mesh complex, loosely dispersed in water, make normal crystallization is destroyed calcium scale. EDTMPS to calcium sulfate, barite ore of scale scale inhibition effect is good.
Second, quality indicators
Accord with HG/T 3538-2003
Eye refers to a standard
