I-Cellulose, i-hydroxyethyl ether (MW 1000000)

I-cellulose hydroxyethyl etheriphuma ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamangqamuzana ezitshalo. Ukuguqulwa kwe-hydroxyethyl ether kubandakanya ukwethula amaqembu e-hydroxyethyl esakhiweni se-cellulose. Isisindo samangqamuzana (MW) esicaciswe njengo-1,000,000 cishe sibhekisela esilinganisweni sesisindo se-cellulose hydroxyethyl ether. Nawa amanye amaphuzu abalulekile mayelana ne-cellulose hydroxyethyl ether enesisindo se-molecular engu-1,000,000:

1. Isakhiwo Sekhemikhali:
   • I-Cellulose hydroxyethyl ether itholakala ku-cellulose ngokuyiphendula nge-ethylene oxide, okuholela ekwethulweni kwamaqembu e-hydroxyethyl kumgogodla we-cellulose.
2. Isisindo se-Molecular:
   • Isisindo samangqamuzana esingu-1,000,000 sibonisa isilinganiso sesisindo samangqamuzana e-cellulose hydroxyethyl ether. Leli nani liyisilinganiso sesisindo esimaphakathi samaketango e-polymer kusampula.
3. Izakhiwo Zomzimba:
   • Izici ezithile ezibonakalayo ze-cellulose hydroxyethyl ether, njengokuncibilika, i-viscosity, namandla okwenza ijeli, kuncike ezintweni ezifana nezinga lokushintsha (DS) nesisindo semolekyuli. Izisindo eziphakeme zamangqamuzana zingathonya i-viscosity nokuziphatha kwe-rheological kwezixazululo.
4. Ukunyibilika:
   • I-Cellulose hydroxyethyl ether ivamise ukuncibilika emanzini. Izinga lokushintshwa kanye nesisindo samangqamuzana lingathinta ukunyibilika kwayo kanye nokugxila lapho yenza khona izixazululo ezicacile.
5. Izicelo:
   • I-Cellulose hydroxyethyl ether enesisindo se-molecular engu-1,000,000 ingathola izinhlelo zokusebenza ezimbonini ezihlukahlukene:
     • Ezemithi: Ingase isetshenziswe ekwenziweni kwezidakamizwa ezikhishwa okulawulwayo, ezinhlobonhlobo zamathebulethi, nezinye izinhlelo zokusebenza zemithi.
     • Izinto zokwakha: Kudaka, ukhonkolo, nezinamatheliso zamathayela ukuze kuthuthukiswe ukugcinwa kwamanzi nokusebenza.
     • I-Coatings and Films: Ekwenziweni kwezigqoko namafilimu ngenxa yezakhiwo zayo zokwenza amafilimu.
     • Imikhiqizo Yokunakekelwa Komuntu Siqu: Ezimonyoni nasezintweni zokunakekela komuntu siqu ngenxa yezakhiwo zayo ezijiyayo neziqinisayo.
6. Ukulawulwa kwe-Rheological:
   • Ukwengezwa kwe-cellulose hydroxyethyl ether kunganikeza ukulawula phezu kwezakhiwo ze-rheological zezixazululo, okwenza kube yigugu ekubunjweni lapho ukulawulwa kwe-viscosity kubalulekile.
7. I-Biodegradability:
   • Ama-cellulose ether, okuhlanganisa nokuphuma kokuphuma kwe-hydroxyethyl ether, ngokuvamile ayabola, okunikela kuphrofayela yawo evumelana nemvelo.
8. I-synthesis:
   • Ukuhlanganiswa kuhilela ukusabela kwe-cellulose nge-ethylene oxide phambi kwe-alkali. Izinga lokushintshwa kanye nesisindo samangqamuzana lingalawulwa phakathi nenqubo yokuhlanganisa.
9. Ucwaningo Nokuthuthukiswa:
   • Abacwaningi nabakhi bangase bakhethe ama-ether e-cellulose e-hydroxyethyl esekelwe esisindweni samangqamuzana nezinga lokushintsha ukuze kuzuzwe izici ezifiselekayo ezinhlelweni ezihlukene.

Kubalulekile ukuqaphela ukuthi izakhiwo kanye nokusetshenziswa kwe-cellulose hydroxyethyl ether kungahluka ngokuya ngezici zayo ezithile, futhi ulwazi olushiwo lunikeza ukubuka konke okujwayelekile. Imininingwane yezobuchwepheshe enemininingwane enikezwe abakhiqizi noma abahlinzeki ibalulekile ukuze uqonde umkhiqizo othize we-cellulose hydroxyethyl ether okukhulunywa ngawo.
