HEDP Cas 2809-21-4 Ethonic Acid Monohydrate
1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Difosphonic Acid (HEDP)
CAS No: 2809-21-4
Qaacidada molecular: C2H8O7P2
Isticmaal
HEDP waa nooc ka mid ah xakamaynta daxalka ee cathodic. Marka la barbardhigo fosfooraska inorganic, waxaa lagu dari karaa molybdate sodium, silicate, zinc milix iyo co-polymer inta badan sida miisaanka daxalka inhibitor inhibitor ee daaweynta ee biyaha qaboojinta wareegga, saliid beerta iyo biyo kululeeyaha .Waxa kale oo loo isticmaali karaa sida sequestrant ee saabuunta iyo wakiilka adag iyo biraha scour ee electroplating.
Sifada
HEDP waxa laga yaabaa inay kala saarto shan ion oo togan ama taban oo ay jeexjeexdo birta labada-valent ee biyaha ku jirta. Sidaas awgeed waxay qaadataa miisaan wanaagsan oo xannibaysa. Alaabtani waxay caddayn u tahay heerkulka sare, oksaydhka iyo qiimaha pH ee sarreeya. Waxay muujineysaa saameyn isku mid ah oo qumman iyo xallinta saameynta xadka iyadoo lagu darayo ka hortagga daxalka kale iyo horjoogayaasha miisaanka.
