Cellulose ether inogona kuvandudza zvakanyanya kushanda kwedhaka rakanyorova, uye ndiyo inonyanya kuwedzera iyo inokanganisa kushanda kwekuvaka kwedhaka. Kusarudzwa kunonzwisisika kwema cellulose ethers emhando dzakasiyana-siyana, viscosities dzakasiyana, zvakasiyana-siyana zvidimbu, madhigirii akasiyana-siyana eviscosity uye yakawedzerwa mari ichava nemigumisiro yakanaka pakuvandudzwa kwekushanda kwevhu rakaoma dhaka.
Kune zvakare hukama hwakanaka hwemutsara pakati pekuenderana kwesamende paste uye dosi ye cellulose ether. Cellulose ether inogona kuwedzera zvakanyanya viscosity yedhaka. Iyo yakakura dosage, zvinonyanya kuoneka mugumisiro. High-viscosity cellulose ether aqueous solution ine high thixotropy, iyo iriwo hunhu hukuru hwe cellulose ether.
Iko kukora mhedzisiro kunoenderana nedhigirii repolymerization ye cellulose ether, solution concentration, shear rate, tembiricha uye mamwe mamiriro. Iyo gelling midziyo yemushonga yakasarudzika kune alkyl cellulose uye yakagadziridzwa maderivatives. Iyo gelation zvivakwa zvine hukama neiyo dhigirii yekutsiva, kugadzirisa kugadzirisa uye zvinowedzera. Kune hydroxyalkyl yakagadziridzwa derivatives, iyo gel zvivakwa zvine hukama zvakare nedhigirii rekuchinja rehydroxyalkyl. 10% -15% mhinduro inogona kugadzirirwa yakaderera-viscosity MC uye HPMC, 5% -10% mhinduro inogona kugadzirirwa yepakati-viscosity MC uye HPMC, uye 2% -3% mhinduro inogona chete kugadzirirwa yakakwirira-viscosity MC. uye HPMC. Kazhinji iyo viscosity classification ye cellulose ether inoiswawo grade 1% -2% mhinduro.
High-molecular-weight cellulose ether ine high thickening kunyatsoshanda. Mapolymer ane uremu hwakasiyana hwemamorekuru ane maviscosities akasiyana mune imwechete yekusimbisa mhinduro. High degree. Iyo inonangwa viscosity inogona kuwanikwa chete nekuwedzera yakawanda yakaderera molecular uremu cellulose ether. Viscosity yaro haina kutsamira pachiyero chekuveura, uye iyo yakakwira viscosity inosvika painotariswa viscosity, uye iyo inodiwa yekuwedzera mari idiki, uye viscosity zvinoenderana nekukora kwekuita. Naizvozvo, kuti uwane kumwe kuenderana, imwe chiyero che cellulose ether (concentration yemhinduro) uye mhinduro viscosity inofanira kuvimbiswa. Iyo tembiricha yegel yemushonga zvakare inodzikira mutsetse nekuwedzera kwekusangana kwemhinduro, uye gels pane tembiricha yekamuri mushure mekusvika kumwe kusungwa. Iyo gelling concentration yeHPMC yakakwira zvakanyanya pakamuri tembiricha.
