Applications

 

HEDP is an organic phosphoric acid corrosion inhibitor . It can chelate with metal ions such as iron , copper and zinc to form a stable complex . It can dissolve the oxidizing substances on the surface of these metals. At 250°C, HEDP shows excellent scale and corrosion inhibition capabilities . HEDP has good chemical stability at high pH , and it is not easy to be hydrolyzed or decomposed under normal light and heating conditions .

 

Its acid/alkali and chlorine oxidation resistance are better than other organic phosphoric acid (salt) . HEDP can react with metal ions in the water system to form a six-element chelate complex , especially with calcium ions . Therefore , HEDP has good scale resistance and visible threshold effect . When used with other water treatment chemicals , it shows good synergy . The solid of HEDP is a high - purity product , suitable for use in winter and frozen areas . It is very suitable for use as a cleaning agent in the electronics field and an additive for household chemicals .
