madzi HEDP 60% 1-Hydroxyethylidene-1,1-diphosphonic asidi cas 2809-21-4 Etidronic acid monohydrate

Mawonekedwe:
HEDP ndi organophosphoric acid corrosion inhibitor. Itha kutsitsa ndi Fe, Cu, ndi Zn etc.
ayoni zitsulo ndi kupanga khola zovuta pawiri.
Ikhoza kusungunula zinthu zomwe zili ndi okosijeni pamtunda wazitsulozi. Pansi pa 250 ℃ HEDP imawonetsa luso labwino kwambiri komanso kuthekera koletsa dzimbiri.
HEDP ili ndi kukhazikika bwino kwa mankhwala pansi pa pH yamtengo wapatali, yovuta kuti ikhale ya hydrolyzed, komanso yovuta kuti iwonongeke pansi pa kuwala wamba ndi kutentha. Kulekerera kwake kwa asidi / alkali ndi klorini kwa okosijeni ndikwabwino kuposa kwa ma organophosphoric acid (mchere).
HEDP imatha kuchitapo kanthu ndi ayoni achitsulo m'madzi kuti apange hexa-element chelating complex, yokhala ndi calcium ion makamaka. Choncho, HEDP ili ndi zotsatira zabwino zotsutsa komanso zowonekera.
Mukamangidwa pamodzi ndi mankhwala ena ochizira madzi, zimawonetsa zotsatira zabwino za synergistic.

Cholimba cha HEDP ndi chinthu choyera kwambiri, choyenera kugwiritsidwa ntchito m'madera ozizira komanso ozizira.
ndizoyenera kugwiritsidwa ntchito ngati zoyeretsera m'magawo amagetsi komanso ngati zowonjezera pamankhwala atsiku ndi tsiku.

Mapulogalamu:
HEDP chimagwiritsidwa ntchito mu kuzungulira dongosolo madzi ozizira mphamvu yamagetsi, makampani mankhwala, zitsulo, feteleza, etc. ndipo chimagwiritsidwa ntchito monga sikelo ndi dzimbiri choletsa wa otsika-anzanu kukanika, madzi osefukira, payipi mafuta.

M'makampani opepuka & nsalu, HEDP imagwiritsidwa ntchito ngati zotsukira zitsulo komanso zopanda zitsulo. M'makampani opaka utoto, HEDP imagwiritsidwa ntchito ngati kukhazikika kwa peroxide ndi kukonza utoto; Mu electroplating yopanda cyanide, HEDP imagwiritsidwa ntchito ngati chelating agent. Mlingo wa 1-10mg/L umasankhidwa ngati scale inhibitor, 10-50mg/L ngati corrosion inhibitor, ndi 1000-2000mg/L ngati detergent. Nthawi zambiri, HEDP imagwiritsidwa ntchito limodzi ndi polycarboxylic acid.
