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

Mawonekedwe:
HEDP ndi choletsa kupangika kwa organophosphorus acid. Imatha kuphatikizika ndi Fe, Cu, ndi Zn ndi zina zotero.
ma ayoni achitsulo ndipo amapanga chophatikizana chokhazikika.
Imatha kusungunula zinthu zomwe zasungunuka pamwamba pa zitsulozi. Pansi pa 250℃ HEDP imasonyeza luso labwino kwambiri loletsa dzimbiri komanso kuletsa dzimbiri.
HEDP imakhala ndi kukhazikika kwabwino kwa mankhwala pansi pa pH yokwera, yovuta kusungunuka ndi madzi, komanso yovuta kusungunuka pansi pa kuwala ndi kutentha kwabwinobwino. Kulekerera kwake kusungunuka kwa asidi/alkali ndi chlorine kuli bwino kuposa kwa ma acid ena a organophosphorus (mchere).
HEDP imatha kuchitapo kanthu ndi ma ayoni achitsulo m'madzi kuti ipange hexa-element chelating complex, makamaka ndi calcium ion. Chifukwa chake, HEDP ili ndi zotsatira zabwino zotsutsana ndi kukula kwa chinthu komanso zowoneka bwino.
Ikapangidwa pamodzi ndi mankhwala ena oyeretsera madzi, imasonyeza zotsatira zabwino zogwirizana.

Cholimba cha HEDP ndi chinthu choyera kwambiri, choyenera kugwiritsidwa ntchito m'nyengo yozizira komanso m'malo ozizira kwambiri.
Ndi yoyenera kugwiritsidwa ntchito ngati chotsukira m'magawo amagetsi komanso ngati zowonjezera mu mankhwala a tsiku ndi tsiku.

Mapulogalamu:
HEDP imagwiritsidwa ntchito kwambiri mu makina amagetsi, makampani opanga mankhwala, zitsulo, feteleza, ndi zina zotero ndipo imagwiritsidwa ntchito kwambiri ngati choletsa dzimbiri cha ma boilers otsika mphamvu, kusefukira kwa madzi m'munda, mapaipi amafuta.

Mu makampani opanga kuwala ndi nsalu, HEDP imagwiritsidwa ntchito ngati sopo wa zitsulo ndi zosakhala zachitsulo. Mu makampani opanga utoto, HEDP imagwiritsidwa ntchito ngati choletsa peroxide komanso chokonzera utoto; Mu makina opangira utoto osagwiritsa ntchito cyanide, HEDP imagwiritsidwa ntchito ngati choletsa chelating. Mlingo wa 1-10mg/L umakondedwa ngati choletsa sikelo, 10-50mg/L ngati choletsa dzimbiri, ndi 1000-2000mg/L ngati sopo. Nthawi zambiri, HEDP imagwiritsidwa ntchito limodzi ndi polycarboxylic acid.
