Ama-cellulose ethers anikeza i-viscosity enhle kakhulu odakeni olumanzi, akhuphula ngokuphawulekayo amandla okubopha odaka olumanzi ku-substrate futhi athuthukise ukumelana nokuntengantenga kodaka, futhi asetshenziswa kabanzi ekwenzeni udaka olunamekiwe, udaka lwebhondi yezitini kanye nezinhlelo zokuhlanganisa zangaphandle.Umthelela wokujiya we-cellulose ether ungaphinda ukhulise ikhono lokulwa nokuhlakazeka kanye ne-homogeneity yezinto ezisanda kuxutshwa, uvimbele ukuhlukaniswa kwezinto, ukuhlukaniswa kanye nokukhishwa kwamanzi, futhi ingasetshenziswa kukhonkolo ye-fiber, ukhonkolo ongaphansi kwamanzi kanye nokhonkolo ozihlanganisayo.
Umthelela wokujiya wama-cellulose ether ezintweni zikasimende uphumela ku-viscosity yesixazululo se-cellulose ether.Ngaphansi kwezimo ezifanayo, ukuphakama kwe-viscosity ye-cellulose ether, i-viscosity yezinto zikasimende eziguquliwe ziba ngcono, kodwa uma i-viscosity iphezulu kakhulu, izoba nomthelela ekutheni i-fluidity nokusebenza kwempahla (isb. imimese enamathelayo).Izinsimbi ezizilinganisa ngokwazo kanye nokhonkolo ozihlanganisayo, odinga uketshezi oluningi, zidinga i-viscosity ephansi ye-cellulose ethers.Ngaphezu kwalokho, umphumela wokujiya we-cellulose ethers wandisa isidingo samanzi sezinto zikasimende futhi ukhuphule isivuno sodaka.
I-viscosity yezixazululo ze-cellulose ether incike ezintweni ezilandelayo: isisindo samangqamuzana e-cellulose ether, ukugxila, izinga lokushisa, izinga le-shear kanye nendlela yokuhlola.Ngaphansi kwezimo ezifanayo, ubukhulu besisindo se-cellulose ether, siphakamisa i-viscosity yesisombululo;ukugxila okuphezulu, ukuphakama kwe-viscosity yesisombululo, ekusetshenzisweni kokunaka kufanele kukhokhwe ukuze kugwenywe i-dosing ngokweqile futhi kuthinte izakhiwo zokusebenza zodaka nokhonkolo;I-viscosity yesisombululo se-cellulose ether izokwehla ngokunyuka kwezinga lokushisa, futhi ukuphakama okuphezulu, ithonya elikhulu lokushisa;Isixazululo se-cellulose ether ngokuvamile siwuketshezi lwe-pseudoplastic, olunemvelo yokunciphisa i-shear, ukuhlolwa okukhulu Isilinganiso esikhulu sokuhlola, i-viscosity encane, ngakho-ke ukuhlangana kodaka kuzoncishiswa ngaphansi kwesenzo samandla angaphandle, okulungele ukwakhiwa kodaka, ukuze udaka lube nokusebenza okuhle nokuhlangana ngesikhathi esifanayo;ngenxa yokuthi isixazululo se-cellulose ether siwuketshezi olungezona olwase-Newton, izindlela zokuhlola i-viscosity yokuhlola, i-instrumentation noma indawo yokuhlola, imiphumela yokuhlolwa yesixazululo se-cellulose ether efanayo ingase yehluke kakhulu.
