Sifa:

HEDP ni kizuizi cha kutu cha asidi ya organophosphoric. Inaweza kuchemka kwa ioni za Fe, Cu, na Zn kuunda misombo ya chelating thabiti. Inaweza kuyeyusha nyenzo zilizooksidishwa kwenye nyuso za metali hizi. HEDP inaonyesha kiwango bora na athari za kuzuia kutu chini ya joto la 250 ℃. HEDP ina uthabiti mzuri wa kemikali chini ya thamani ya juu ya pH, ni ngumu kwa hidrolisisi, na ngumu kuoza chini ya mwanga wa kawaida na hali ya joto. Ustahimilivu wake wa asidi/alkali na oxidation ya klorini ni bora zaidi kuliko ule wa asidi zingine za organophosphoric (chumvi). 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.

Hali thabiti ya 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.

Matumizi:

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.

Ufungaji na uhifadhi:

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

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

Hifadhi kwa miezi kumi na mbili katika chumba chenye kivuli na mahali pakavu.

Usalama na ulinzi:

HEDP ina tindikali. Makini na ulinzi wa kazi wakati wa operesheni. Epuka kuwasiliana na macho na ngozi. Ikiwa hunyunyiza kwenye mwili, suuza mara moja na maji mengi.
