Ethers Cellulose-Biyo-Luulaya
Biyo-milmi karaethers cellulosewaa koox ka mid ah soosaarayaasha cellulose kuwaas oo awood u leh inay ku milmaan biyaha, iyagoo siinaya waxyaabo gaar ah iyo hawlqabadyo. Ether-yadan cellulose-ka ah waxay ka helaan codsiyo ballaaran warshado kala duwan sababtoo ah kala duwanaanshahooda. Waa kuwan qaar ka mid ah ether-yada cellulose-ka ee biyaha ku milma ee caadiga ah:
- Hydroxypropyl Methylcellulose (HPMC):
- Qaab dhismeedka: HPMC waa eter cellulose biyo-milmi leh oo laga soo qaatay cellulose iyada oo la soo bandhigayo hydroxypropyl iyo kooxaha methyl.
- Codsiyada: HPMC waxaa si weyn loogu isticmaalaa agabka dhismaha (sida alaabada sibidhka ku salaysan), dawooyinka (sida xidhidaha iyo wakiilka sii-deynta), iyo alaabta daryeelka shakhsi ahaaneed (sida dhumuc ahaan).
- Carboxymethyl Cellulose (CMC):
- Qaab dhismeedka: CMC waxaa lagu helaa iyadoo la soo bandhigayo kooxaha karboksymethyl ee laf dhabarta cellulose.
- Codsiyada: CMC waxa ay caan ku tahay haynta biyaha, dhumucdeeda, iyo guryaha xasilinta. Waxa loo isticmaalaa alaabta cuntada, daawooyinka, dunta, iyo sidii wax ka beddelka rheology ee qaabab kala duwan.
- Hydroxyethyl Cellulose (HEC):
- Qaab dhismeedka: HEC waxaa lagu soo saaraa etherifying cellulose leh ethylene oxide.
- Codsiyada: HEC waxaa sida caadiga ah loo isticmaalaa rinjiyada biyaha ku salaysan iyo dahaarka, alaabta daryeelka shakhsi ahaaneed (shamboo, labeen), iyo dawooyinka sidii dhumuc iyo xasiliye.
- Methyl Cellulose (MC):
- Qaab dhismeedka: MC waxaa laga soo qaatay cellulose iyadoo lagu beddelayo kooxaha hydroxyl kooxaha methyl.
- Codsiyada: MC waxa loo isticmaalaa dawooyinka (sida xidhe iyo kala daadsan), alaabta cuntada, iyo warshadaha dhismaha si ay u haynta biyaha ee hoobiye iyo nuuradda.
- Ethyl Cellulose (EC):
- Qaab dhismeedka: EC waxaa lagu soo saaraa iyadoo la soo bandhigayo kooxaha ethyl ee laf dhabarta cellulose.
- Codsiyada: EC waxaa inta badan loo isticmaalaa warshadaha dawooyinka loogu talagalay daahan filimada ee kiniiniyada, iyo waxa ay sidoo kale ka shaqeeya in wax soo saarka ee hababka sii daayo la xakameeyey.
- Hydroxypropyl Cellulose (HPC):
- Qaab dhismeedka: HPC waxaa lagu soo saaraa iyadoo la soo bandhigayo kooxaha hydroxypropyl ee laf dhabarta cellulose.
- Codsiyada: HPC waxa loo isticmaalaa dawooyinka sida xidhe iyo kala daadsanaan, iyo sidoo kale alaabta daryeelka shakhsi ahaaneed ee sifooyinka dhumucdiisuna.
- Sodium Carboxymethyl Cellulose (Na-CMC):
- Qaab dhismeedka: Wuxuu la mid yahay CMC, laakiin qaabka cusbada soodhiyamka.
- Codsiyada: Na-CMC waxaa si weyn loogu isticmaalaa sidii dhumuc iyo xasiliye warshadaha cuntada, iyo sidoo kale daawooyinka, dunta, iyo codsiyada kale.
Guryaha Muhiimka ah iyo Hawlaha Ethers Cellulose-Biyuhu-Maska:
- Dhumucdi: Ether-ka cellulose-ka biyaha ku milma ayaa ah dhumucyo wax ku ool ah, siinta viscosity xalalka iyo qaabaynta.
- Xasilinta: Waxay gacan ka geystaan xasilinta emulsions iyo joojinta.
- Sameynta Filimka: Qaar ka mid ah ethers cellulose, sida EC, ayaa loo isticmaalaa codsiyada samaynta filimada.
- Haysashada Biyaha: Eter-yadani waxay kor u qaadi karaan haynta biyaha ee agabyada kala duwan, iyaga oo ka dhigaya kuwo qiimo leh xagga dhismaha iyo warshadaha kale.
- Biodegradability: Qaar badan oo ka mid ah ether-ka cellulose-ka ee biyaha ku milma ayaa ah biodegradable, oo gacan ka geysta hababka deegaanka u saaxiibka ah.
Eter-ka cellulose-ka gaarka ah ee loo doortay codsiga waxay ku xiran tahay sifooyinka la rabo iyo shuruudaha alaabta ugu dambeysa.
