Mfumo wa Molekuli: C₂H₄O₇P₂Tayari₄ Uzito wa molekuli: 294

Mfumo wa Muundo:

Sifa:

HEDP•Katika₄ ni chumvi ya sodiamu HEDP, HEDP•Katika₄ ni kizuizi kizuri cha kalsiamu carbonate, inaweza kutumika katika mfumo wa maji wa boiler ya shinikizo la chini, mfumo wa maji unaozunguka, mfumo wa maji wa kusafisha viwanda na manispaa na bwawa la kuogelea.

The solid HEDP•Na₄ poda nyeupe, mumunyifu katika maji, kwa urahisi deliquescence, yanafaa kwa ajili ya matumizi katika majira ya baridi na wilaya kufungia. Ni aina ya kiwango cha asidi ya organophorphonic na kizuizi cha kutu, inaweza kuunda tata na Fe, Cu na Zn ions, inaweza kufuta oksidi kwenye uso wa chuma, ina kiwango kizuri na athari ya kuzuia kutu chini ya 250 ℃.

HEDP•Katika₄ is widely used in circulating cool water system, medium and low pressure boiler, oil field water pipelines as scale and corrosion inhibitor in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP•Na₄ is used as detergent for metal and nonmetal. In dyeing industry, HEDP•Na₄ is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP•Na₄ hutumika kama wakala wa chelating.
