Yiziphi izinzuzo ze-cellulose?

I-Cellulose iwuhlobo lwe-cellulose ukukhiqizwa nokusetshenziswa kwayo kuzokhula ngokushesha. I-ether engeyona i-inorganic cellulose exutshwe ngekotini ecolisisiwe ngemva kokubola, kusetshenziswa i-propylene oxide ne-methyl chloride njengama-etherification agents, futhi ngochungechunge lokusabela. Izinga lokushintsha ngokuvamile liyi-1.2 ~ 2.0. Izici zayo zihlukile ngenxa yezilinganiso ezihlukene zezingxenye ze-tert-butyl kanye nezingxenye ze-hydroxypropyl.

(1) I-Cellulose iyancibilika emanzini abandayo, futhi kuyoba nzima ukuyincibilika emanzini abilayo. Kodwa izinga lokushisa layo le-gelatinization emanzini abilayo liphakeme kakhulu kune-carboxycellulose. Isimo sokuhlakazeka emanzini abandayo sithuthuke kakhulu uma siqhathaniswa ne-carboxycellulose.

(2) I-viscosity ye-cellulose ihlobene nosayizi wesisindo samangqamuzana ahlobene, futhi uma ubukhulu be-molecular mass ehlobene, ukuphakama kwe-viscosity kuya phezulu. Ukushisa kuzophinde kuthinte i-viscosity yayo, izinga lokushisa liyakhuphuka, i-viscosity iyancipha. Kodwa i-viscosity yayo ephezulu kanye nokushisa okuphezulu akuyingozi kakhulu kune-carboxycellulose. Isixazululo saso esinamanzi sizinzile lapho sigcinwe ekamelweni lokushisa.

(3) Ukugcinwa kwamanzi kanye nokuncibilika kwe-cellulose kusenani layo elingeziwe, i-viscosity, njll., futhi izinga layo lokugcinwa kwamanzi ngaphansi kwenani elifanayo lokwengezwa liphakeme kunalelo le-carboxycellulose.

(4) I-Cellulose imelana ne-asidi ne-alkali, futhi ikhambi layo lizinzile kakhulu ebangeni le-pH=2~12. I-anhydrous aluminium chloride kanye ne-lime slurry azinawo umthelela omkhulu ezintweni zayo, kodwa i-alkali ingasheshisa izinga lokuncibilika kwayo futhi ithuthukise ukubukeka kwayo. I-Cellulose inokwethenjelwa kusawoti we-asidi evamile, kodwa lapho ukugxila kwesisombululo sikasawoti kuphezulu, i-viscosity yesisombululo se-cellulose ivame ukwanda.

(5) I-Cellulose ingasetshenziswa nama-polymers ancibilikayo emanzini ukwenza i-uniform kanye ne-high-viscosity solution yamanzi. Okufana ne-acrylic emulsion, i-tapioca isitashi ether, iglue yemifino, njll.

(6) I-Cellulose inokumelana ne-enzyme enamandla kune-carboxycellulose, futhi isixazululo sayo esinamanzi mancane amathuba okuthi incibilikiswe ama-enzyme kune-carboxycellulose.

(7) Ukunamathela kwe-cellulose ekwakhiweni kodaka lukasimende kuphakeme kunaleyo ye-carboxycellulose.
