Izakhiwo ze-Methyl Cellulose
I-Methyl cellulose (MC) iyi-ether ye-cellulose enezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezihlukahlukene, okuhlanganisa ukudla, imithi, kanye nezokwakha.Ezinye zezakhiwo ze-MC zihlanganisa:
- Ukunyibilika: I-MC iyancibilika emanzini futhi ingakha isixazululo esicacile nesizinzile ekamelweni lokushisa.Iphinde inyibilike kwezinye izincibilikisi eziphilayo, njenge-ethanol ne-methanol.
- I-Viscosity: I-viscosity yezixazululo ze-MC incike ezintweni ezimbalwa, okuhlanganisa izinga lokushintsha, isisindo samangqamuzana, nokugxila kwesisombululo se-MC.Izixazululo ze-MC zibonisa ukuziphatha kokugeleza okungekona okwaseNewtonian, okusho ukuthi i-viscosity iyashintsha ngesilinganiso sokugunda.
- Ukwenza ifilimu: I-MC ingenza ifilimu uma incibilika emanzini bese yomiswa.Ifilimu eyakhiwe yi-MC iyaguquguquka, isobala, futhi inezakhiwo ezinhle zokuthiya.
- Ukuzinza kwe-thermal: I-MC inokusimama okuhle kwe-thermal futhi ingamelana nezinga lokushisa elifika ku-200°C ngaphandle kokuwohloka okukhulu.
- Ukuhambisana: I-MC iyahambisana nezinye izinto eziningi, okuhlanganisa nezinye i-cellulose ethers, isitashi, namaprotheni.
- I-Hydrophilicity: I-MC ine-hydrophilic kakhulu, okusho ukuthi inobudlelwane obuqinile bamanzi.Lesi sakhiwo senza i-MC ibe usizo ekwakhiweni lapho ukugcinwa kwamanzi kubalulekile, njengokudla nemikhiqizo yokunakekelwa komuntu siqu.
Sekukonke, izakhiwo ze-MC ziyenza ibe yinto eguquguqukayo engasetshenziswa ezinhlelweni eziningi ezahlukahlukene.
