Cellulose, hydroxyethyl ether (MW 1000000)

Cellulose hydroxyethyl etherwaa nooc ka mid ah cellulose, oo ah polymer dabiici ah oo laga helo gidaarada unugyada dhirta. Wax ka beddelka hydroxyethyl ether waxay ku lug leedahay soo bandhigida kooxaha hydroxyethyl qaab dhismeedka cellulose. Miisaanka molecular (MW) ee lagu tilmaamay sida 1,000,000 waxay u badan tahay inuu tixraaco celceliska miisaanka kelli ee cellulose hydroxyethyl ether. Waa kuwan qaar ka mid ah qodobbada muhiimka ah ee ku saabsan cellulose hydroxyethyl ether oo miisaankeedu yahay 1,000,000:

1. Qaab dhismeedka Kiimikada:
   • Cellulose hydroxyethyl ether waxay ka soo baxdaa cellulose iyada oo ka falcelinaysa ethylene oxide, taasoo keentay in kooxaha hydroxyethyl ay soo galaan laf-dhabarka cellulose.
2. Miisaanka Molecular:
   • Miisaanka molecular ee 1,000,000 wuxuu muujinayaa celceliska miisaanka kelli ee cellulose hydroxyethyl eter. Qiimahani waa cabbirka celceliska tirada silsiladaha polymer-ka ee muunadda.
3. Qalabka Jirka:
   • Astaamaha jireed ee gaarka ah ee cellulose hydroxyethyl ether, sida solubility, viscosity, iyo gel-samaynta awoodaha, waxay ku xidhan yihiin arrimo ay ka mid yihiin heerka beddelka (DS) iyo miisaanka kelli. Miisaannada unugyada unugyada sare waxay saameyn karaan viscosity iyo habdhaqanka rheological ee xalalka.
4. Xalka:
   • Cellulose hydroxyethyl ether caadi ahaan waxay ku milmaan biyaha. Heerarka beddelka iyo miisaanka kelliku waxay saameyn karaan milmayntiisa iyo xoogga saarista taas oo ay ku sameyso xalal cad.
5. Codsiyada:
   • Cellulose hydroxyethyl ether oo leh miisaan kelli ah 1,000,000 waxay ka heli kartaa codsiyo warshado kala duwan:
     • Daawooyinka: Waxa laga yaabaa in loo isticmaalo qaabaynta dawooyinka la xakameeyey, dahaarka kiniinka, iyo codsiyada kale ee dawooyinka.
     • Qalabka Dhismaha: Hoobiyaha, balastarrada, iyo xabagta tile-ka si loo hagaajiyo xajinta biyaha iyo shaqaynta
     • Dahaarka iyo Filimada: Soo saarista dahaarka iyo filimada ee sifooyinka sameynta filimada.
     • Alaabooyinka Daryeelka Shakhsi ahaaneed: Qalabka la isku qurxiyo iyo alaabta daryeelka shakhsi ahaaneed ee dhumucdooda iyo xasilinta guryaha.
6. Xakamaynta rheological:
   • Ku darida cellulose hydroxyethyl ether waxay ku siin kartaa xakamaynta sifooyinka rheological ee xalalka, taas oo ka dhigaysa mid qiimo leh qaababka halka xakamaynta viscosity ay lagama maarmaan tahay.
7. Waxyeellada noolaha:
   • Ethers Cellulose, oo ay ku jiraan hydroxyethyl ether derivatives, guud ahaan waa biodegradable, wax ku biirinaya muuqaalkooda deegaanka saaxiibtinimo.
8. Synthesis:
   • Isku-dubaridku waxay ku lug leeyihiin falcelinta cellulose leh ethylene oxide ee joogitaanka alkali. Heerka beddelka iyo miisaanka kelli waa la xakameyn karaa inta lagu jiro habka isku-dhafka.
9. Cilmi-baarista iyo Horumarinta:
   • Cilmi-baadhayaashu waxay dooran karaan ethers cellulose hydroxyethyl gaar ah oo ku salaysan miisaanka molecular iyo heerka beddelka si loo gaaro guryaha la rabo ee codsiyada kala duwan.

Waxaa muhiim ah in la ogaado in sifooyinka iyo codsiyada cellulose hydroxyethyl ether ay ku kala duwanaan karaan iyada oo ku saleysan sifooyinkeeda gaarka ah, iyo macluumaadka la xusay ayaa bixiya dulmar guud. Xog farsamo oo faahfaahsan oo ay bixiyaan soosaarayaasha ama alaab-qeybiyeyaasha ayaa muhiim u ah fahamka sheyga gaarka ah ee cellulose hydroxyethyl ether ee su'aasha ah.
