HEDP Cas 2809-21-4 Etidronic Acid Monohydrate
1-Hydroxyethylidene-1,1-diphosphonic aside / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Diphosphonic acid (HEDP)
Nimero ya CAS: 2809-21-4
Formula ya Molecular: C2H8O7P2
Koresha
HEDP ni ubwoko bw'umuti ubuza gushonga kwa katodike. Ugereranyije na fosifate zidafite umwimerere, ishobora kuvangwa na sodium molybdate, silicate, umunyu wa zinc na co-polymer cyane cyane nk'umuti ubuza gushonga kwa karike mu kuvura amazi akonjesha, umuriro w'amavuta n'amazi ashyushya. Ishobora kandi gukoreshwa nk'umuti ugabanya ubushyuhe mu isabune n'ibikoresho bigabanya ubushyuhe ndetse no gushonga ibyuma mu buryo bwa electroplating.
Ibiranga
HEDP ishobora kuva kuri iyoni eshanu nziza cyangwa mbi, igatera iyoni y'icyuma ifite valent ebyiri mu mazi. Bityo, ifata ingaruka nziza zo kugabanya ubushyuhe. Iki gicuruzwa ni ikimenyetso cyo kwirinda ubushyuhe bwinshi, ogisijeni n'agaciro ka pH kari hejuru. Igaragaza ingaruka nziza za synergic kandi igakemura ikibazo mu gihe ivanze n'izindi anticorrosive corrosion na scale inhibitors.

Imikoreshereze
HEDP ishobora kuvangwa na aside hydroxylaectic, PAA, BTA, molybdate, copolymer, umunyu wa zinc, kugira ngo bikoremo alkali y’umwimerere cyangwa fosforasi nkeya mu gutunganya amazi kugira ngo ikoreshwe mu bwoko bwose bw’amazi akonjesha butandukanye n’ubwiza bw’amazi. Igipimo muri rusange ni 2-10mg/L mu gihe HEDP ikoreshwa yonyine.
Ipaki n'ububiko
Ingoma ya pulasitiki ifite ibiro 250 cyangwa IBC ifite ibiro 1250, igomba kubikwa mu cyumba gikonje kandi gihumeka neza kandi gitanga umwuka mu gihe cy'umwaka.
Turagusaba kutwandikira kugira ngo ubone COA na MSDS. Murakoze.
