HEDP•Na₄ bụ sodium nnu nke HEDP, HEDP•Na₄ bụ ihe mgbochi dị mma maka calcium carbonate, enwere ike iji ya na usoro mmiri ọkụ ọkụ dị ala, usoro mmiri na-ekesa, ụlọ ọrụ mmepụta ihe na ime obodo na-ehicha mmiri na ọdọ mmiri.

The solid HEDP•Na₄ bụ ọcha ntụ ntụ, soluble na mmiri, mfe deliquescence, adabara ojiji na oyi na kefriza districts. Ọ bụ ụdị organophorphonic acid ọnụ ọgụgụ na corrosion inhibitor, nwere ike na-etolite siri ike na Fe, Cu na Zn ion, ọ nwere ike igbari oxides na metal elu, ọ nwere ezi ọnụ ọgụgụ na corrosion inhibition mmetụta n'okpuru 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 a na-eji ya dị ka onye na-ahụ maka chelate.
