suppliers of poly aluminium chloride whit from South Korea
Properties: HEDP 60 is an excellent corrosion inhibitor and antiscalant.HEDP 60% can dissolve the oxidized materials on these metals’ surfaces. It shows the excellent scale and corrosion inhibition effects under temperature 250℃. Under high pH value and/or 250℃, HEDP 60% shows good chemical stability. It is difficult to be decomposed by normal light and heat conditions.
HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
