Ifomula yemolekyuli: C₂H₆O₇P₂Sele₂ Ubunzima bemolekyuli: 250

Ifomula yoLwakhiwo:

Iinkcazelo ngeempawu:

HEDP•Na₂ i-organophosphonic acid corrosion inhibitor, inokutshiza nge-Fe, Cu, kunye ne-Zn ion, inokunyibilikisa izinto ezixutywe ne-oxidized, inomlinganiselo omhle kunye nemiphumo yokuthintela ukubola nangaphantsi kwe-250 ℃, izinzile phantsi kwexabiso eliphezulu le-pH, akukho lula ibe yi-hydrolyzed, ingabi lula ukubola phantsi kokukhanya okuqhelekileyo kunye nemeko yokushisa, ukunyamezela kwayo i-asidi / i-alkaline kunye ne-chloride oxidation ingcono kunezinye i-organophosph-onic acids. HEDP•Na₂ inokwenza i-6-ring chelating compounds kunye ne-ion zetsimbi kwinkqubo yamanzi, i-Ca2 + ngokukodwa. HEDP•Na₂ ineempembelelo zesikali esilungileyo kunye neziphumo ezicacileyo zokupheliswa. Xa isetyenziswe kunye namanye amachiza onyango lwamanzi, iziphumo ze-synergistic zingcono.

Ukusetyenziswa:

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 isetyenziswa njenge arhente chelating.
