Hoʻohana:

HEDP•Na₂ 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•Na₂ is used as detergent for metal and nonmetal. In dyeing industry, HEDP•Na₂ is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP•Na₂ hoʻohana ʻia ma ke ʻano he chelating agent.
