HEDP Cas 2809-21-4 Etidronic Acid Monohydrate
1-Hydroxyethylidene-1,1-diphosphonic asiidh / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP)
Lambarka CAS: 2809-21-4
Qaacidda Molekuleeri: C2H8O7P2
Isticmaal
HEDP waa nooc ka mid ah daawada katooliga ee daxalka. Marka la barbardhigo fosfates-ka aan organic-ga ahayn, waxaa lagu dari karaa sodium molybdate, silicate, milixda zinc iyo co-polymer inta badan sida daawada daxalka miisaanka ee daaweynta biyaha qaboojinta wareega, iftiinka goobta saliidda iyo biyaha kuleyliyaha. Waxa kale oo loo isticmaali karaa sidii sequestrant ee saabuunta iyo wakiilka isku dhafan iyo xoqidda birta ee electroplating.
Sifo
HEDP waxay u kala bixi kartaa shan ion oo togan ama taban waxayna ku milmi kartaa ion-ka birta laba-valent biyaha. Sidaas darteed waxay qaadataa saameyn xakameyn miisaan wanaagsan. Alaabtani waa caddayn ka dhan ah heerkulka sare, oksaydhka iyo qiimaha pH sare. Waxay muujinaysaa saameyn isku-dhafan oo qumman iyo saameynta xallinta heerka iyadoo lagu darayo daawooyinka kale ee ka hortagga daxalka iyo kuwa ka hortagga miisaanka.

Isticmaalka
HEDP waxaa lagu dari karaa hydroxylaectic acid, PAA, BTA, molybdate, copolymer, milix zinc ah, si loo sameeyo wakiil biyo ah oo dabiici ah ama fosfoor hooseeya oo zinc ku salaysan oo loo isticmaali karo dhammaan noocyada nidaamyada biyaha qaboojinta wareegga ah oo ka duwan tayada biyaha. Qiyaasta guud ahaan waa 2 ~ 10mg/L halka HEDP keligiis la isticmaalo.
