Details
HEDP is an organic phosphonic acid corrosion inhibitor,which can chelate with Fe, Cu, and Zn ions to form stable chelating compounds and dissolve the oxidized materials on these metal's surfaces.
It shows excellent scale and corrosion inhibition effects under temperature 250℃, good chemical stability at high pH value. For this reason, it is hard to be hydrolyzed and decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than other organic phosphonic acids (salt).
Moreover, the HEDP acid can react with metal ions,calcium ion in particular in the water system to form a hexa-element chelating complex,therefore it with good antiscale and visible threshold effects. When built together with other water treatment chemicals, HEDP shows good synergistic effects.
The solid state of HEDP has high purity, so is suitable for usage in winter and freezing districts, also it can be used as a cleaning agent in electronic fields and as additives in daily chemicals.
The usual dosage of 1-10mg/L is preferred , 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as cleaning agent. Usually, HEDP is used together with polycarboxylic acid.
Packed in plastic drums, net weight 25kg per drum.
Store in a cool, dry place indoors with a shelf life of one years.
