Properties:

HEDP•In₄ ndiyo sodium munyu we HEDP, HEDP•In₄ is a good scale inhibitor for calcium carbonate, inogona kushandiswa mu low pressure boiler water system, circulating water system, maindasitiri nekanzuru yekuchenesa mvura system uye swimming pool.

The solid HEDP•Na₄ upfu chena, soluble mumvura, nyore deliquescence, yakakodzera kushandiswa muchando uye nechando matunhu. Imhando ye organophorphonic acid scale uye corrosion inhibitor, inogona kuumba yakagadzikana yakaoma neFe, Cu uye Zn ions, inogona kunyungudutsa maokisisi pamusoro pesimbi, ine chiyero chakanaka uye corrosion inhibition effect pasi pe250 ℃.

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 inoshandiswa se chelating agent.
