Focus on Cellulose ethers

Izici zesakhiwo se-cellulose ether kanye nomthelela wayo kuzakhiwo zodaka

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 eziyingqayizivele ziyenza ibe isithasiselo esifanelekile sezingoma zodaka. 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
