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, milixda zinc iyo co-polymer inta badan sida miisaanka daxalka inhibitor ee daaweynta biyaha qaboojinta wareegga, saliidda goobta saliidda iyo biyaha kululeeyaha .Waxa kale oo loo isticmaali karaa sida sequestrant ee saabuunta iyo wakiilka kakan iyo scour biraha 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.Markaa waxay qaadanaysaa miisaan wanaagsan oo joojinaysa saamaynta.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.
