Yintoni umahluko phakathi kwe-cellulose ether kunye ne-cellulose?

I-cellulose kunye ne-cellulose ether zombini ziphuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. Nangona kunjalo, banomahluko ohlukileyo kwizakhiwo zabo zeekhemikhali kunye neempawu:

1. Ubume beMichiza: I-Cellulose yi-polysaccharide ehambelanayo equka ukuphindaphinda iiyunithi ze-glucose ezidityaniswe kunye ne-β (1→ 4) iibhondi ze-glycosidic. Yipolymer yekhonkco elithe tye kunye neqondo eliphezulu le-crystallinity.
2. I-Hydrophilicity: I-Cellulose ngokwemvelo i-hydrophilic, oku kuthetha ukuba inobudlelwane obuqinileyo namanzi kwaye inokufunxa inani elikhulu lokufuma. Le propati ichaphazela ukuziphatha kwayo kwizicelo ezahlukeneyo, kubandakanywa ukusebenzisana kwayo kunye neenkqubo ezisekelwe emanzini ezifana nemixube yesamente.
3. Ukunyibilika: I-cellulose ecocekileyo ayinyibiliki emanzini kwaye uninzi lwezinyibilikisi ze-organic ngenxa yesakhiwo sayo sekristale ephezulu kunye ne-hydrogen ebanzi yokudibanisa phakathi kwamakhonkco e-polymer.
4. I-Derivatization: I-ether ye-Cellulose luhlobo olulungisiweyo lweselulosi efunyenwe nge-chemical derivatization. Le nkqubo ibandakanya ukwazisa amaqela asebenzayo, afana ne-hydroxyethyl, i-hydroxypropyl, i-methyl, okanye amaqela e-carboxymethyl, kwi-cellulose backbone. Olu tshintsho luguqula iipropathi zeselulosi, kubandakanywa ukunyibilika kwayo, ukuziphatha kwerheological, kunye nokusebenzisana nezinye izinto.
5. Ukunyibilika emanzini: I-cellulose ethers iqhele ukunyibilika okanye ihlakazeke emanzini, kuxhomekeke kuhlobo oluthile kunye neqondo lokutshintsha. Oku kunyibilika kubenza babe luncedo kakhulu kumashishini ahlukeneyo, kubandakanya amayeza, ukutya, izinto zokuthambisa, kunye nokwakha.
6. Isicelo: I-Cellulose ethers ifumana ukusetyenziswa ngokubanzi njengee-agent ezityebisayo, izizinzi, izibophelelo, kunye nee-ejenti zokwenza ifilimu kwiimveliso ezahlukeneyo kunye neenkqubo. Ekwakhiweni, zisetyenziswa ngokuqhelekileyo njengezongezo kwizinto ezisekelwe kwisamente ukuphucula ukusebenza, ukugcinwa kwamanzi, ukunamathela kunye nezinye iipropati.

Isishwankathelo, ngelixa i-cellulose kunye ne-ether ye-cellulose yabelana ngemvelaphi efanayo, i-ether ye-cellulose iguqulwa ngokwemichiza ukwazisa iimpawu ezithile ezenza ukuba zinyibilike okanye zichitheke emanzini kwaye zilungele izicelo ezahlukeneyo apho ukulawula ukuziphatha kwe-rheological kunye nokusebenzisana nezinye izinto ezifunwayo.
