Cellulose ether inowanzova chinhu chakakosha mumatope akaoma-akasanganiswa.Nekuti chinhu chakakosha chekuchengetedza mvura mumiriri ane yakanakisa kuchengetedza mvura.Ichi chivakwa chekuchengetedza mvura chinogona kudzivirira mvura iri mudhaka rakanyorova kuti isanyungudika nguva isati yakwana kana kunyudzwa neiyo substrate, kurebesa nguva yekushanda yedhaka rakanyorova, ive nechokwadi chekuti simende yakazara hydrated, uye nekudaro inopedzisira yave nechokwadi chemichina yedhaka, iyo. inonyanya kubatsira pakuvaka dhaka rakatetepa (sekupurasita dhaka) uye dhaka mune zvakanyanya kunyura substrates (senge aerated kongiri zvidhinha), tembiricha yepamusoro uye yakaoma mamiriro.
Iyo yekuchengeta mvura pfuma ye cellulose ine hukama zvakanyanya neiyo viscosity.Iyo yakakwirira viscosity ye cellulose ether, zviri nani kuchengetedza mvura kuita.Viscosity chinhu chakakosha parameter yeMC performance.Parizvino, vagadziri veMC vakasiyana vanoshandisa nzira dzakasiyana uye zviridzwa kuyedza viscosity yeMC, uye nzira huru ndiHaake Rotovisko, Hoppler, Ubbelohde uye Brookfield.Pachigadzirwa chimwe chete, mhedzisiro yeviscosity yakayerwa nenzira dzakasiyana inosiyana zvakanyanya, uye dzimwe dzakatosiyana zvakanyanya.Naizvozvo, kana uchienzanisa viscosities, zvakakosha kuzviita pakati peiyo nzira dzekuyedza, kusanganisira tembiricha, rotor, nezvimwe.
Kazhinji kutaura, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura.Zvisinei, iyo yakakwirira ye viscosity, iyo yakakwirira ye molecular huremu hweMC uye inowirirana inoderera mukunyungudika kwayo, iyo ine mhedzisiro yakaipa pakusimba uye kuita kwekuvaka kwedhaka.Iyo yakakwirira viscosity, iyo inonyanya kuoneka iyo thickening maitiro padhaka.Iyo yakakwirira iyo viscosity, iyo inonamira iyo dhaka yakanyorova ichave, zvese mukuvaka, sezvakaratidzwa neinonamira scraper uye yakakwirira kunamatira kune substrate.Zvisinei, hazvibatsiri zvakanyanya kuwedzera simba rekugadzirisa dhaka rakanyorova pacharo.Kana zvese zviri zviviri kuvaka, zvinoratidza iyo anti-sagging kuita haisi pachena.Pane zvinopesana, imwe yakaderera kusvika pakati viscosity asi yakagadziridzwa methyl cellulose ethers ine basa rakanakisa mukuvandudza simba rechimiro chedhaka rakanyorova.
