I-Cellulose Ether ingathuthukisa kakhulu ukusebenza ngodaka olumanzi, futhi isengezo esikhulu esithinta ukusebenza kodaka. Ukukhetha okunengqondo kwezithambekela ze-cellulose yezinhlobo ezahlukahlukene, ama-viscosities ahlukene, ama-degree ahlukile wezinhlayiya, ama-degree ahlukene wokubonakala kanye namanani angeziwe azoba nomthelela omuhle ekuthuthukisweni koMuder oQinisekayo.
Kukhona nobudlelwano obuhle obuqondile phakathi kokuvumelana kokufana kukakhonkolo kanye nomthamo we-cellulose ether. I-Cellulose Ether ingakhulisa kakhulu ukubonana kodaka. Okukhudlwana umthamo, umphumela osobala. Isixazululo esiphakeme se-cellule
Umphumela wokuqina uncike ngezinga le-polymerization ye-cellulose ether, ukugxila kwesixazululo, izinga lokushisa, izinga lokushisa kanye nezinye izimo. Impahla ecebile yesisombululo ihlukile ku-ALKYL Cellulose kanye nama-derivatives alo aguquliwe. Izakhiwo ze-gelation zihlobene nezinga lokufaka esikhundleni, ukugxilisa izixazululo kanye nezithasiselo. Nge-Hydroxyalkyl Decivatives eguquliwe, izakhiwo ze-gel nazo zihlobene neziqu zokuguqulwa kwe-hydroxyalkyl. Isixazululo esingu-10% -15% singalungiswa i-LOG-Vissusity FUSTNC kanye ne-HPMC, isixazululo esingu-5% -10% singalungiswa ku-MC ebonakalayo ye-MC ne-HPMC, futhi isixazululo esingu-2% -3% singalungiswa kuphela i-st-vissusity ephezulu ne-HPMC. Imvamisa ukuhlukaniswa kwe-viscosity ye-cellulose ether nakho kufakwe i-1% -2% solution.
I-ether ye-cellulose ephezulu-molecular-cellulose ether isebenza kahle kakhulu. Ama-polymers anama-molefanelar izinsimbi ane-viscosities ehlukile kusixazululo esifanayo sokuhlushwa. Degree ephezulu. I-Viscosity Target ingatholakala kuphela ngokungeza inani elikhulu le-molecular isisindo se-cellulose ether. I-viscosity yayo inokuncika okuncane kwezinga le-shear, futhi i-viscosity ephezulu ifinyelela ekuboniseni okuqondiwe, futhi inani lentengo elidingekayo lincane, futhi i-viscoty incike ekusebenzeni kahle. Ngakho-ke, ukufeza ukungaguquguquki okuthile, inani elithile le-cellulose ether (ukugxila kwesixazululo) nesixazululo kufanele kuqinisekiswe. Izinga lokushisa le-gel lesixazululo libuye linciphise ngokuqondile ngokwanda kokuqoqwa kwesixazululo, nama-gel ama-gels ekushiseni kwekamelo ngemuva kokufinyelela kokuhlushwa okuthile. Ukuhlushwa kwama-gelling kwe-HPMC kuphakeme kakhulu emazingeni okushisa asekamelweni.
