Properties:

HEDP•Na₄ dia ny sira sodium ny HEDP, HEDP•Na₄ dia inhibitor mizana tsara ho an'ny karibonetra kalsioma, azo ampiasaina amin'ny rafitra rano boiler tsindry ambany, rafitra rano mivezivezy, rafitra rano fanadiovana indostrialy sy monisipaly ary dobo filomanosana.

The solid HEDP•Na₄ dia vovoka fotsy, mety levona anaty rano, mora deliquescence, mety ampiasaina amin'ny ririnina sy ny faritra mangatsiaka. Izany dia karazana organophorphonic asidra mizana sy ny harafesiny inhibitor, dia afaka mamorona mafy orina sarotra amin'ny Fe, Cu sy Zn ion, dia afaka handrava ny oxides amin'ny vy ambonin'ny, dia manana ambaratonga tsara sy ny harafesiny inhibition vokany eo ambanin'ny 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 dia ampiasaina ho chelating agent.
