Cellulose, hydroxyetyl ​​ether (mw 1000000)

Clucolose hydroxytylytyl ether etherWaa soo-saareynta unugyada unugyada dabiiciga ah, polymmer dabiici ah oo laga helo darbiyada unugyada ee dhirta. Dib-u-habeynta hydroxyletyletyl ether waxay ku lug leedahay soo bandhigida kooxaha hydroxytyl ee qaab dhismeedka unugyada. Miisaanka Moleculal (MW) oo loo cayimay in 1,000,000 ay suuragal tahay in ay u badan tahay celceliska culeyska molikal ee unugyada unugyada unugyada unugyada unugyada. Waa kuwan qaar ka mid ah qodobbada muhiimka ah ee ku saabsan unugyada unugyada hydroxytyl ether ether culays molikal ah oo ah 1,000,000:

1. Qaab dhismeedka kiimikada:
   • Cilmi-jabka cludroxyletyletyl ether ether ayaa laga soo qaatay cellulose isagoo ka falgalaya ethylenenene oxide, taasoo keentay in la soo bandhigo kooxaha hydroxytyl ceyrta laf-dhabarka.
2. Miisaanka Moleculal:
   • Miisaankii Moleculal ee 1,000,000 ayaa muujinaya celceliska culeyska molikal ee unugyada unugyada unugyada unugyada gulukytyletyl ether ether. Qiimahaani waa cabir celcelis ahaan tirada badan ee silsiladaha polymer ee muunadda.
3. Guryaha jireed:
   • Sifooyinka gaarka ah ee jirka ee unugyada unugyada unugyada unugyada ah ee hydroxyletyl ether, sida jilicsanaanta, viscosity, iyo awoodaha sameysashada, iyo awoodaha gel-abuurka, waxay kuxirantahay qodobbada sida heerka beddelka (DS) iyo miisaanka molikal. Miisaannada molika ee sare waxay saameyn ku yeelan karaan viscosity iyo dhaqanka xalka xalka.
4. Xoobi:
   • Cilmiga cudurka cludroxytyletyl ether caadi ah ayaa sida caadiga ah biyaha ku milatari. Heerka beddelka iyo miisaanka molikal waxay saameyn ku yeelan kartaa xalideeda iyo uruurinta ay ku samayso xalal cad.
5. Codsiyada:
   • Cellulose hydroxytyletyl ether oo culeys molikalar ah oo ah 1000,000 ayaa ka heli kara codsiyada warshadaha kala duwan:
     • Dawooyinka: Waxaa loo isticmaali karaa in lagu xakameeyo dawooyinka la xakameeyo ee la xakameeyo, jaakadaha kiniiniga, iyo codsiyada kale ee dawooyinka.
     • Qalabka dhismaha
     • Xirmooyinka iyo filimada: wax soo saarka jaakad iyo filimaanta guryaha filim sameeyadooda.
     • Alaabada daryeelka shakhsi ahaaneed: ee ku jira waxyaabaha la isku qurxiyo iyo waxyaabaha daryeelka shakhsi ahaaneed ee qaro weyn iyo xasilinta guryaha.
6. Xakamaynta Rhekta:
   • Ku darista bylulose hydroxyletyletyl ether ether waxay bixin kartaa xakameyn ku saabsan guryaha rheolololojiyada ee xalka, taasoo qiimo u leh gudbinta meesha ay taakuleyntu ay muhiim tahay.
7. Balanqaadyada:
   • Qiyaasta unugyada, oo ay ku jiraan hydroxytyletyl as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as as asyroxykylykyl ', guud ahaan waa noolaha loo isticmaali karo, kuna tabarucaya taariikhdooda bey'adda saaxiibtinimo.
8. Synthesis:
   • Isku-darka isku-darka ayaa ku lug leh jawaab celinta unugyada cellulose ee leh ethylenenene ovide joogitaanka alkali. Heerka beddelka iyo miisaanka molikal waxaa lagu xakamayn karaa inta lagu gudajiro geedi socodka isku-darka.
9. Cilmi baarista iyo horumarka:
   • Baarayaasha iyo qaabaraduhu waxay dooran karaan unugyada unugyada gaarka ah ee hyroxyetyl ​​ku saleysan culeyska molikal iyo heerka beddelka si loo gaaro guryaha la doonayo ee ku jira codsiyada kaladuwan.

Waxaa muhiim ah in la ogaado in guryaha iyo codsiyada unugyada unugyada unugyada unugyada unugyada unugyada unugyada unugyada ay kululaato ay ku kala duwanaan karaan iyadoo lagu saleynayo astaamaha gaarka ah, iyo macluumaadka soo sheegay ayaa bixiya dulmar guud. Xog farsamo oo faahfaahsan oo ay bixiyeen soosaarayaasha ama alaab-qeybiyeyaasha ayaa muhiim u ah fahamka garashada unugyada gaarka ah ee hydroxytylty ether su'aasha.
