Ama-cellulose ethers amahle kakhulu
Ama-cellulose ethers awumndeni wama-polymers ancibilika emanzini asuselwa ku-cellulose, i-polymer eyenzeka ngokwemvelo etholakala ezindongeni zamaseli ezitshalo. Lawa ma-derivatives ama-polymer e-cellulose ashintshwe ngamakhemikhali anamaqembu ahlukahlukene asebenzayo, anikeza izakhiwo ezithile kuma-molecule. Ama-cellulose ether asetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yokuguquguquka kwawo, okuhlanganisa ezokwakha, ezemithi, ukudla, izimonyo, nokunye.
Ukunquma i-cellulose ether “engcono kakhulu” kuncike ezidingweni ezithile zohlelo oluhlosiwe. Ama-ether e-cellulose ahlukene abonisa izici ezihlukahlukene, ezifana ne-viscosity, ukuncibilika, nekhono lokwenza ifilimu, okuwenza afanelekele izinjongo ezihlukile. Nawa amanye ama-cellulose ether asetshenziswa kakhulu futhi abhekwa kahle:
- I-Methyl Cellulose (MC):
- Izakhiwo: I-MC yaziwa ngomthamo wayo ophezulu wokugcina amanzi, okuyenza ifanelekele ukusetshenziswa ekushubeni kwezicelo, ikakhulukazi embonini yezokwakha. Ibuye isetshenziswe emikhiqizweni yokudla kanye nemithi.
- Izicelo: Ukwakhiwa kodaka nosimende, amaphilisi emithi, nanjenge-ejenti yokuqina emikhiqizweni yokudla.
- I-Hydroxyethyl Cellulose (HEC):
- Izakhiwo: I-HEC inikezela ngokuncibilika kahle kwamanzi futhi iguquguquka ngokwemibandela yokulawulwa kwe-viscosity. Ivame ukusetshenziswa kokubili emikhiqizweni yezimboni kanye nabathengi.
- Izicelo: Opende nezingubo zokugqoka, imikhiqizo yokunakekelwa komuntu siqu (ama-shampoos, ama-lotions), izinto zokunamathisela, kanye nokwakheka kwemithi.
- I-Carboxymethyl Cellulose (CMC):
- Izakhiwo: I-CMC iyancibilika emanzini futhi inezakhiwo ezinhle kakhulu zokujiya nokuzinza. Isetshenziswa kabanzi ezimbonini zokudla nezamakhemisi.
- Izicelo: Imikhiqizo yokudla (njenge-thickener and stabilizer), imithi, izimonyo, izindwangu, noketshezi lokumba embonini kawoyela negesi.
- IHydroxypropyl Methyl Cellulose (HPMC):
- Izakhiwo: I-HPMC inikeza ibhalansi enhle yokuncibilika kwamanzi, ukugeleza kwe-thermal, nezakhiwo zokwenza ifilimu. Isetshenziswa kabanzi ekwakhiweni nasekusetshenzisweni kwemithi.
- Izicelo: Okunamathiselwe kuthayela, ama-render asekelwe kusimende, ukwakheka kwemithi yomlomo, kanye nezinhlelo zokulethwa kwezidakamizwa ezikhishwa okulawulwayo.
- I-Ethyl Hydroxyethyl Cellulose (EHEC):
- Izakhiwo: I-EHEC yaziwa nge-viscosity yayo ephezulu kanye nokugcinwa kwamanzi, okuyenza ifanelekele izicelo ezifunayo ekwakhiweni nasekusetshenzisweni kwemithi.
- Izicelo: Izithasiselo zodaka, ama-ejenti okuqina kwezokwelapha, nezimonyo.
- I-Sodium Carboxymethyl Cellulose (Na-CMC):
- Izakhiwo: I-Na-CMC iyi-ether ye-cellulose encibilika emanzini enezakhiwo ezinhle kakhulu zokujiya nokuzinza. Ivame ukusetshenziswa ekudleni nasezinhlelweni ezihlukahlukene zezimboni.
- Izicelo: Imikhiqizo yokudla (njenge-thickener and stabilizer), imithi, izindwangu, kanye noketshezi lokumba.
- I-Microcrystalline Cellulose (MCC):
- Izakhiwo: I-MCC iqukethe izinhlayiya ezincane, ezicwebezelayo futhi ivamise ukusetshenziswa njengesihlanganisi nesigcwalisi kumaphilisi emithi.
- Izicelo: Amaphilisi emithi namaphilisi.
- I-Sodium Carboxymethyl isitashi (CMS):
- Izakhiwo: I-CMS iwumphumela wesitashi onezakhiwo ezifana ne-Na-CMC. Isetshenziswa kakhulu embonini yokudla.
- Izicelo: Imikhiqizo yokudla (njenge-thickener ne-stabilizer), izindwangu, kanye nemithi.
Uma ukhetha i-cellulose ether yohlelo oluthile, kubalulekile ukucabangela izici ezifana ne-viscosity edingekayo, ukuncibilika, ukuzinza, nezinye izici zokusebenza. Ukwengeza, ukuhambisana nezindinganiso zokulawula kanye nokucatshangelwa kwemvelo kufanele kucatshangelwe. Abakhiqizi bavame ukuhlinzeka ngamashidi edatha obuchwepheshe ngolwazi olunemininingwane mayelana nezakhiwo kanye nokusetshenziswa okunconyiwe kwama-cellulose ethers athile.
