Haydroxyethyl Cellulose (HEC)
Cellulose-ka Hydroxyethyl(HEC)
CAS:9004-62-0
Cellulose-ka Hydroxyethyl(HEC) waa cellulose ether-ka aan biyaha ku milmin ee aan ionic ahayn, oo loo isticmaalo dhumuc-dhejin, kolloid ilaalin ah, wakiilka haynta biyaha iyo wax-ka-beddelka rheology-ga ee codsiyada kala duwan sida rinjiyada biyaha ku salaysan, qalabka dhismaha, kiimikooyinka goobta saliidda iyo alaabada daryeelka shakhsi ahaaneed. Sababo la xiriira sifooyinkeeda gaarka ah, sida dheellitirka sare, milmida biyaha kulul iyo qabow, iyo xasilloonida kiimikada, HEC waa maaddooyin muhiim ah oo ku jira badeecooyin badan oo warshadeed iyo macaamiil ah.
HEC waxaa lagu sameeyaa iyadoo kooxaha hydroxyethyl (-CH₂CH₂OH) lagu soo daro silsiladda polymer-ka cellulose iyada oo loo marayo falgal etherification ah. Wax-ka-beddelkani wuxuu hagaajiyaa milmida biyaha, awoodda dhumucda, iyo iswaafajinta qaacidooyinka kala duwan.

Faa'iidooyinka Muhiimka ah:
1. Haysashada Biyaha oo Aad u Fiican: Waxay ka caawisaa ka hortagga qallajinta degdega ah ee alaabada ku salaysan sibidhka iyo qurxinta.
2. Xasilloon oo ku baahsan baaxadda pH-ga oo ballaaran: Waxay waxtar u leedahay deegaannada aashitada, dhexdhexaadka ah, iyo kuwa alkaline-ka ah.
3. Aan Ionic ahayn oo la jaanqaadi kara: Si fiican ayuu ula shaqeeyaa kiimikooyin kala duwan, oo ay ku jiraan milix, surfactants, iyo polymers kale.
4. Waxay kor u qaadaysaa waxqabadka badeecada: Waxay hagaajisaa dhumucda, dhegdhegga, sameynta filimka, iyo sifooyinka emulsification.
5. Deegaan ahaan u wanaagsan oo baabi'in kara: Iyada oo laga soo qaatay cellulose, HEC ma aha mid sun ah oo baaba'aya.
6. Waxay hagaajisaa sifooyinka Rheology iyo Socodka: Waxay u ogolaataa daxalka la xakameeyey, iyadoo ka hortageysa daadashada, libdhidda, iyo kala-goynta wejiga.
Baakadaha:
Badeecada HEC waxaa lagu soo buuxiyay bac warqad ah oo saddex lakab ah oo leh bac gudaha ah oo polyethylene ah oo la xoojiyay, miisaanka saafiga ahna waa 25kg bacdiiba.
Kaydinta:
Ku hay bakhaar qabow oo qalalan, ka fog qoyaanka, qorraxda, dabka, iyo roobka.
