HEDP•Na₄ ndi mchere wa sodium HEDP, HEDP•Na₄ ndi inhibitor yabwino ya calcium carbonate, imatha kugwiritsidwa ntchito pamakina ocheperako opopera madzi, makina ozungulira amadzi, makina otsuka am'mafakitale ndi matauni ndi dziwe losambira.

The solid HEDP•Na₄ ndi ufa woyera, sungunuka m'madzi, mosavuta deliquescence, oyenera ntchito yozizira ndi kuzizira zigawo. Ndi mtundu wa organophorphonic acid sikelo ndi dzimbiri inhibitor, akhoza kupanga khola zovuta ndi Fe, Cu ndi Zn ayoni, akhoza kupasuka oxides pamwamba zitsulo, ali ndi sikelo yabwino ndi dzimbiri chopinga kwenikweni pansi 250 ℃.

HEDP•Na₄ 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 amagwiritsidwa ntchito ngati chelating agent.
