Cellulose Ether o etsa seretse se metsi se nang le pono e ntle haholo, e ka eketsa bokhoni ba ho ba le seretse le seretse sa seretse sa seretse. E sebelisoa haholo ho Startring, Sistimi ea kantle ea Instsian ea kantle ho litene. Tšusumetso e tona ea khepho ea khelolu e ka boela ea eketsa homogeneity ea thepa le ho hanyetsa, 'me e ka sebelisoa konkreiti ea sefahleho le konkreiti.
Cellulolose Ether o eketsa tlhahlobo ea thepa ea thibelo ea samente e tsoang ho bona. Index ea "pono" hangata e sebelisoa ho lekola liketsahalo tsa tharollo ea cellulose. Kelello ea cellulose e bua ka tharollo ea selefou e nang le mahloriso a itseng (joalo ka 2%). Lebelo (kapa sekhahla sa ho potoloha le ho potoloha ka 20 rpm), boleng ba viscosion bo lekantsoeng ka sesebelisoa se boletsoeng (joalo ka ha e le hantle.
Viscosity ke paramente ea bohlokoa ho lekola tšebetso ea Cellulo Mouther. Tse ling tsa pono e phahameng ea tharollo ea lisebelisoa tsa cellulose, e leng hantle viscoseity ea thepa e thehiloeng ho thibela Haeba pono ea eona e phahame haholo, e tla ama phofo le ts'ebetso ea lintho tse thehiloeng ho mofuta oa lehola (tse kang ho khomarela lisemane nakong ea ho hloekisa katolosong). Ka hona, lintho li nkuoa ka seretse sa cellulose e sebelisoang serekeng se ommeng hangata se ka 15,000 ~ 60,000 mpa. S-1 le ho iphapanyetsa konkreiti le boithati, tse hlokang ho phoqa tse phahameng, li hloka pono e tlase ea cellulose ether.
Ntle le moo, phello e matla ea ho ruteha ea khepho ea cellulose e eketsa tlhoko ea metsi a thepa e thehiloeng ho ea thibela, ka ho etsa joalo e eketsa chai ea seretse.
Viscosity of the Celulo Mouther o its'etleha ka lintlha tse latelang:
Boima ba limocular (kapa degree of polymerization) le khatello ea kelello e ngata, tharollo ea mocheso, sekhahla sa shear le mokhoa oa liteko le mokhoa oa tlhahlobo le mokhoa oa liteko.
1. Ha a phahamisitse palo ea polymerization ea cellulose ether, e leng boima ba moleng, le ho feta ha pono ea tharollo ea eona e halefileng;

3. Joalo ka lino tse ngata, pono ea viccosity ea li-cellulose e ngata e tla fokotseha ka keketseho ea mocheso, le khatello ea maikutlo ea selefoule e kholo letšolo la mocheso;
4. Hangata tharollo ea cellulose ether ke pseudoplane, e nang le thepa ea shear e busang. Lekhabunyane le leholo la shear nakong ea teko, ho theola Viscosity.
Ka hona, bokoko bo tla fokotsoa ka lebaka la matla a kantle, a lokelang ho aha seretse, hoo se sethala se ka bang le ho ntlafatsa le ho bulutla hantle ka nako e le 'ngoe. Leha ho le joalo, tharollo ea lilululose e tla bontša litšobotsi tsa Newtonian Flitonian ha khatello e tlase haholo 'me pono e le nyane haholo. Ha mahloriso a eketseha, tharollo e tla bonts'a mefuta ea metsi a pseudoprottic metsi, le ea pele, e totobetseng ho feta pseudoplation.
