Sharaxaada Alaabta:
Hydroxyethyl cellulose (HEC) waa jaale cad ama khafiif ah, aan ur lahayn, budo aan sun ahayn. Waxaa laga diyaariyaa cellulose aasaasiga ah iyo ethylene oxide (ama chloroethane) iyada oo etherification. Waa eter cellulose milmaya aan ionic ahayn. Sababtoo ah HEC cellulose waxay leedahay sifooyin wanaagsan oo dhumucdiisuna, ganaax, kala firidhsan, emulsification, adhesion, samaynta filimka, ilaalinta qoyaanka, iyo ilaalinta colloid, waxaa si ballaaran loo isticmaalaa soo saaridda batroolka, dahaarka, dhismaha, daawada iyo cuntada, dunta, waraaqaha, iyo beeraha kale.
Codsiga:
1. Hydroxyethyl cellulose budada waxaa lagu milmi karaa biyo kulul iyo qabow, mana soo da'ayaan marka la kululeeyo ama la karkariyo. Sababtaas awgeed, waxay leedahay noocyo kala duwan oo milmayn iyo sifooyin viscosity iyo non-thermogelability.
2. HEC waxay la noolaan kartaa polymers-ka kale ee biyaha ku milma, surfactants, iyo cusbada. HEC waa dhumuc weyn oo kolloidal ah oo ka kooban xalal koronto-saar sare leh.
3. Awoodeeda xajinta biyaha waxay laba jeer ka badan tahay tan methylcellulose, waxayna leedahay nidaaminta socodka wanaagsan.
4. Marka la barbardhigo methylcellulose iyo hydroxypropylmethylcellulose, HEC waxay leedahay awoodda kolloid ee ugu xooggan.
Warshadaha Dhismaha: HEC waxaa loo isticmaali karaa sidii wakiilka qoyaanka celiya iyo dejinta sibidhka.
Wershada Qodista Saliidda: Waxa loo isticmaali karaa sidii dhumuc iyo shabidh-samaynta dareeraha ceelka saliidda. Dheecaanka qodista leh HEC wuxuu si wax ku ool ah u wanaajin karaa xasilloonida qodista iyadoo lagu saleynayo shaqadiisa hoose ee adag.
Warshadaha Dahaarka: HEC waxay door ka ciyaari kartaa dhumucdiyada, emulsinta, kala firdhinta, xasilinta iyo haynta biyaha agabka cinjirka Waxaa lagu gartaa saameyn dhumuc weyn leh, faafinta midabka wanaagsan, sameynta filimka, iyo xasilloonida kaydinta.
Warqad iyo Khad: Waxaa loo isticmaali karaa sidii wakiilka cabbirka warqadaha iyo sabuuradaha, sidii dhumuc iyo hakinta khadadka biyaha ku salaysan.
Kiimikooyinka Maalinlaha ah: HEC waa wakiil samaynta filim wax ku ool ah, dhejiyeyaal, dhumuc weyn, xasiliya oo kala firdhiya shaambada, qaboojiyaha timaha, iyo waxyaalaha la isku qurxiyo.
Xidhmada: 25 kgs/bac ama sida aad codsato.
Kaydinta: Ku kaydi meel hawo leh oo qallalan.
Heerarka laga saaray: Heerka caalamiga ah.
