Applications:
EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It shows excellent scale inhibition ability under temperature 200 . It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium sulfate.
Usage:
EDTMPS can be used as corrosion inhibitor in cyclic cooling water system and boiler water, metal chelate agent and color fixing agent for print and textile, etc.
When used alone, 2~10mg/L is preferred. When built with HPMA by ratio ETDMP: HPMA=1:3, it can be used for low pressure boiler. It can also be built with BTA, PAAS and zinc salt.
Package and Storage:
Normally in 30kg or 250kg net Plastic Dram, IBC's drum can be used as required. Stored in cool and ventilated room in one year.
