ethula:
Ama-cellulose ethers ayizithasiselo ezisetshenziswa kakhulu embonini yezokwakha.Isetshenziswa njenge-thickener, stabilizer kanye ne-binder ekwakhiweni kodaka.Izici eziyingqayizivele zesakhiwo sama-cellulose ethers ziwenza abe izithasiselo ezifanele ekufakweni kodaka.Inhloso yaleli phepha ukuxoxa ngomthelela we-cellulose ethers ezindaweni zodaka kanye nezakhiwo zayo zesakhiwo.
Izici zesakhiwo:
Ama-cellulose ether ama-polymers okwenziwa atholakala ku-cellulose (udaba lwezitshalo).Amaketanga e-polymer ku-cellulose ethers aqukethe amaqembu e-hydroxyl awenza akwazi ukwakha izibopho ze-hydrogen nama-molecule amanzi.Lesi sakhiwo sithuthukisa ikhono lokujiya lama-cellulose ethers ezinhlelweni ezinamanzi.
I-Cellulose ether nayo ayiyona i-nonionic, okusho ukuthi ayikhokhisi.Lokhu kuthuthukisa ukuhambisana kwayo nezinye izakhi ohlelweni lodaka.Imvelo engeyona eye-ionic iphinde ivimbele ukunqwabelana kwezindleko ze-electrostatic ezingadala izinkinga ngokufakwa kodaka.
Umthelela kuzakhiwo zodaka:
Ukwengeza ama-cellulose ether ekwakhiweni kodaka kunezinzuzo ezimbalwa.Enye yezinzuzo eziphawuleka kakhulu yikhono layo lokuthuthukisa ukusebenza kahle.I-cellulose ethers yandisa i-viscosity yodaka, okwenza kube lula ukuyifaka phezulu.Iphinde ithuthukise izakhiwo ze-thixotropic zodaka, okwenza kube lula ukugeleza ngesikhathi sokwakhiwa kodwa lukhuni ngokushesha ngemva kokwakhiwa.
Enye inzuzo yama-cellulose ethers yikhono lawo lokuthuthukisa ukugcinwa kwamanzi kwezinhlelo zodaka.Ukugcinwa kwamanzi kubalulekile ezinhlelweni zodaka njengoba kuvumela udaka ukuthi lwelaphe ngendlela efanele.Ikhono le-cellulose ether ukwenza amabhondi e-hydrogen nama-molecule wamanzi lithuthukisa amandla okugcina amanzi odaka futhi livimbele udaka ukuthi lome ngokushesha.
Ama-cellulose ether angaphinda athuthukise izici zokunamathela zezinhlelo zodaka.I-viscosity eyandayo yodaka yenza kube lula ukunamathela ezindaweni ezingaphezulu, kuyilapho izakhiwo zayo ze-thixotropic ziqinisekisa ukuthi udaka lunamathela ngokuqinile ngemva kokufaka isicelo.Izakhiwo ezithuthukisiwe zokubopha nazo zinciphisa amathuba okuba imifantu yakheke ohlelweni lodaka.
Ekuphetheni:
Sengiphetha, ama-cellulose ether ayizithasiselo ezibalulekile embonini yezokwakha.Izakhiwo zayo ezihlukile ziyenza ibe isithasiselo esifanelekile sokuqanjwa kodaka.Ukwengezwa kwama-cellulose ethers ezinhlelweni zodaka kuletha izinzuzo ezifana nokusebenza okuthuthukisiwe, ukugcinwa kwamanzi kanye nezakhiwo zokunamathela.Umphumela omuhle we-cellulose ethers ezindaweni zodaka ubenze babe yingxenye ebalulekile yemboni yezokwakha
