Iinkcazelo ngeempawu:

HEDP yi-organophosphoric acid corrosion inhibitor. Inokuthi i-chelate kunye ne-Fe, Cu, kunye ne-Zn ions ukwenza iikhompawundi ze-chelating ezizinzile. HEDP ibonisa isikali esigqwesileyo kunye neziphumo zokuthintela umhlwa phantsi kobushushu obungama-250 ℃. HEDP inozinzo lwekhemikhali elungileyo phantsi kwexabiso eliphezulu le-pH, kunzima ukuba i-hydrolyzed, kwaye kunzima ukubola phantsi kokukhanya okuqhelekileyo kunye neemeko zobushushu. I-asidi yayo / i-alkali kunye nokunyamezela kwe-chlorine oxidation kungcono kunezinye i-organophosphoric acids (ityuwa). 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.

Ubume obuqinileyo be HEDP is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.

Ukusetyenziswa:

HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.

Ukupakishwa kunye nokugcinwa:

HEDP liquid: 200L plastic drum,IBC(1000L),customers’ requirement.

HEDP solid: 25kg/bag,customers’ requirement.

Ukugcinwa kweenyanga ezilishumi elinesibini kwigumbi elinomthunzi kunye nendawo eyomileyo.

Ukhuseleko kunye nokhuseleko:

I-HEDP ineasidi. Nika ingqalelo ekukhuselweni kwabasebenzi ngexesha lokusebenza. Kuphephe ukudibana namehlo kunye nolusu. Ukuba itshiza emzimbeni, yihlambe ngokukhawuleza ngamanzi amaninzi.
