Hedp is an organophosphoric acid corrosion inhibitor. It can chelate with fe, cu, and zn ions to form stable chelating compounds.It can dissolve the oxidized materials on these metals¡¯ surfaces. Hedp shows excellent scale and corrosion inhibition effects under temperature 250¡æ. Hedp has good chemical stability under high ph value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance ar Hedp liquid: normally in 250kg net plastic drum, ibc drum can also be used as required hedp solid: 25kg inner liner polyethylene (pe) bag, outer plastic woven bag, or confirmed by clients.
