Izakhiwo ze-Physicochemical of Cellulose Afers

I-Cellulose AfersKhombisa uhla lwezakhiwo ze-physicochemical ezibenza ziguquguquke futhi ziluleke ngezicelo ezahlukahlukene. Izakhiwo ezithile zingahluka ngokuya ngohlobo lwe-cellulose ether, izinga lokufaka esikhundleni, nezinye izinto. Nazi ezinye izakhiwo ze-physicochemical ze-cellulose afes:

1. I-Solubity:
   • I-Solubity yamanzi: Ngokuvamile izipho ze-Cellulose zivame ukuncibilikisa amanzi, okuyisici esiyisisekelo esibenza balungele izinhlelo eziningi zezicelo. I-solubity ingahluka phakathi kokutholwa okuhlukile.
2. I-Viscosity:
   • Izakhiwo ezijikelezayo: Enye yezinto ezibaluleke kakhulu ze-cellulose afers ngekhono lazo lokukhulisa izixazululo. I-viscosity yesixazululo ithonywa yizinto ezifana nezinga lokufaka esikhundleni, isisindo se-molecular, kanye nokuhlushwa kwe-cellulose ether.
3. Ukwakheka kwamafilimu:
   • Ikhono elenziwa ngefilimu: Ezinye izithambekele ze-cellulose, kuya ngohlobo lwazo kanye nebanga, zinamandla okwenza amafilimu. Le mpahla isetshenziswa kuzinhlelo zokusebenza ezinjengezimbobo, lapho ifilimu efanayo efiselekayo.
4. Degree of substitution (DS):
   • Ukuguqulwa Kwamakhemikhali: Izinga lokufakwa esikhundleni lisho inani eliphakathi le-hydroxyethyl noma amaqembu we-hydroxypropyl ngamunye uphiko lwe-glucose ku-cellulose chain. Ithonya i-solubity, ukuhlakanipha nezinye izakhiwo ze-cellulose afes.
5. Isisindo samangqamuzana:
   • Ithonya ekubonakaleni: isisindo samangqamuzana se-cellulose afers singaba nomthelela ekubonakaleni kwabo kanye nezakhiwo zokuqina. Isisindo esiphakeme se-molecular cellulose Taelsose singakhombisa ukubonakala okukhulu kwesixazululo.
6. I-Gelation:
   • Izakhiwo ezenziwe nge-gel: Kuya ngohlobo nemibandela, izithiyo ze-cellulose zingabonisa izakhiwo ze-gelation. Lokhu kungabaluleka kuzinhlelo zokusebenza lapho kufana khona ne-gel
7. Umsebenzi ongaphezulu:
   • I-Emulsation kanye nokuzinza: Amanye ama-cellulose afers anezindawo ezisebenzayo, ezenza zisebenze kahle ama-emulsifiers kanye nezinkomo lapho ukuqina kwe-emulsion kubalulekile.
8. I-Hygroscopicity:
   • Ukugcinwa kwamanzi: Abathengisi beCellulose baziwa ngemvelo yabo ye-hygroscopic, ebavumela ukuthi bagcine amanzi. Le mpahla ibalulekile kuzinhlelo zokusebenza ezifana nezinto zokwakha, lapho ukugcinwa kwamanzi kubalulekile ekuphuleni nasekusebenzeni kahle.
9. PH Sensitivity:
   • Ukuvumelana kwe-PH: Ukuzwela kwe-PH Sensitivity of Cellulose Afers kuyinto ebalulekile ekusetshenzisweni okuhlukahlukene. Amanye ama-cellulose afers angabonisa ukuhlukahluka ezindaweni ezisuselwa ku-pH yesisombululo.
10. Adhesion:
    • Izakhiwo ezinamathela: Kuzinhlelo zokusebenza ezinjengezinamathiseli kanye nezimbobo, izivumelwano ze-cellulose zinomthelela ekunamatheleni. Bangathuthukisa isibopho phakathi kwezinto zokwakha.
11. Izakhiwo ze-Rheological:
    • Ithonya ekuziphatheni kwe-Flow: Abafelekisi beCellulosi

Ukuqonda lezi zindawo ze-physicochemical kubalulekile ekukhetheni i-ether ye-cellulose efanelekile ukuthola izinhlelo ezithile. Abakhiqizi bahlinzeka ngemininingwane enemininingwane kanye namashidi wedatha yezobuchwepheshe achaza lezi zindawo zamabanga ahlukene nezinhlobo zezimpi ze-cellulose.
