Ifomula Yesakhiwo:

Izakhiwo:

I-HEDP•In₄ usawoti we-sodium we HEDP, I-HEDP•In₄ iyi-inhibitor yesikali esihle se-calcium carbonate, ingasetshenziswa ohlelweni lwamanzi okushisa okuphansi, uhlelo lwamanzi ajikelezayo, uhlelo lwamanzi okuhlanza izimboni nomasipala kanye nedamu lokubhukuda.

The solid HEDP•Na₄ iyimpushana emhlophe, encibilika emanzini, i-deliquescence kalula, ilungele ukusetshenziswa ezifundeni zasebusika nezibandayo. Iwuhlobo lwe-organophorphonic acid esikalini kanye ne-corrosion inhibitor, ingakha inkimbinkimbi ezinzile nge-Fe, Cu kanye ne-Zn ions, ingancibilikisa ama-oxide endaweni yensimbi, inesilinganiso esihle kanye nomphumela wokugqwala ongaphansi kuka-250 ℃.

I-HEDP•In₄ 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 isetshenziswa njenge-ejenti ye-chelating.
