CAS No. 29329-71-3 (x-Na), 3794-83-0 (4-Na) Synonyms: Tetrasodium etidronate

Molekulýar formula: C.₂H₄O₇P₂Eýýäm₄ Molekulýar agram: 294

Gurluş formulasy:

Aýratynlyklary:

HEDP•Na₄ natriý duzudyr HEDP, HEDP•Na₄ kalsiý karbonat üçin oňat ölçegli inhibitor, pes basyşly gazan suw ulgamynda, aýlanylýan suw ulgamynda, senagat we şäher arassalaýyş suw ulgamynda we basseýninde ulanylyp bilner.

The solid HEDP•Na₄ ak poroşok, suwda ereýär, gyşda we doňan etraplarda ulanmak üçin amatly. Organoforfon kislotasynyň masştabynyň we poslama inhibitorynyň bir görnüşi, Fe, Cu we Zn ionlary bilen durnukly toplum döredip biler, oksidleri metal üstünde eräp biler, oňat masştab we poslama garşy täsir 250 250 under.

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 aldaw serişdesi hökmünde ulanylýar.
