Cellulose etherendows dhaka rakanyorova rine yakanakisa viscosity, inogona kuwedzera zvakanyanya kugona kwekubatana kwevhu rakanyorova uye huswa, kuvandudza mashandiro e-anti-sag edhaka, anoshandiswa zvakanyanya mu plaster dhaka, yekunze insulation system uye zvidhinha bonding dhaka.The thickening effect ye cellulose ether inogonawo kuwedzera kufanana uye anti-kupararira kugona kwezvinhu zvitsva zvesimende, kudzivirira stratification, kupatsanurwa uye kubuda ropa kwedhaka nekongiri, inogona kushandiswa mufiber concrete, pasi pemvura kongiri uye self-compacting kongiri.
Cellulose etherinowedzera viscosity yesimende-yakavakirwa zvinhu kubva kune viscosity ye cellulose ether mhinduro.Kazhinji shandisa "viscosity" iyi metric kuongorora cellulose ether solution viscosity, viscosity ye cellulose ether inowanzoreva imwe fungidziro (2%) ye cellulose ether solution, tembiricha (20 ℃) uye shear rate (kana kutenderera kumhanya, se20 RPM) mamiriro, ane zvipimo zvechiridzwa chekuyeresa, senge kutenderera viscometer kuyerwa viscosity kukosha.Viscosity ndiyo yakakosha parameter yekuongorora kushanda kwe cellulose ether uye cellulose ether, iyo yakakwira viscosity yemhinduro, zvirinani viscosity yesimende base zvinhu, viscosity yehwaro zvinhu inogona, sag kuramba uye kuramba kune kwakasimba kugona kwekuparadzira, asi kana viscosity yakakurisa, inogona kukanganisa sement base zvinhu kufamba uye maneuverability (sekuvakwa kwepurasita dhaka rinonamira plaster).Nokudaro, viscosity ye cellulose ether inoshandiswa mudhaka yakaoma-yakasanganiswa inowanzoita 15,000 ~ 60,000 Mpa.s-1, uye viscosity ye cellulose ether inodiwa kuti ive yakaderera kune yega-leveling dhaka uye self-compactconcrete ine yakakwirira fluidity zvinodiwa.Uye zvakare, iyo thickening mhedzisiro ye cellulose ether ichawedzera kudiwa kwemvura yesimende-yakavakirwa zvinhu, nokudaro kuwedzera kubuda kwedhaka.Iko viscosity ye cellulose ether mhinduro inotsamira pane molecular huremu (kana dhigirii repolymerization) uye kusungirirwa kwe cellulose ether, tembiricha yemhinduro, shear rate, uye nzira yekuyedza.Iyo yakakwirira iyo polymerization degree ye cellulose ether, iyo yakakura iyo molecular uremu, iyo yakakwirira viscosity yeaqueous solution;Iyo yakakwirira iyo dosage (kana kusungirirwa) ye cellulose ether, iyo yakakwirira viscosity yeaqueous solution, asi mukushandiswa kunofanirwa kutarisisa kusarudzwa kweyero yakakodzera, kuitira kuti isasanganise zvakanyanya, inokanganisa kushanda kwedhaka nekongiri;Kufanana nezvinwiwa zvakawanda, viscosity ye cellulose ether mhinduro inodzikira nekuwedzera kwekushisa, uye iyo yakanyanya kuwanda kwe cellulose ether, iyo yakanyanya mhedzisiro yekupisa;Cellulose ether solution inowanzova pseudoplastic body ine pfuma yeshear kuonda.Iyo yakakwirira ye shear rate, yakaderera iyo viscosity.
Nokudaro, kubatanidzwa kwedhaka kuchaderedzwa nechisimba chekunze, iyo inobatsira pakuchera kuvaka kwedhaka, kugadzira dhaka kunogona kuva nekushanda kwakanaka uye kubatana.Nekudaro, cellulose ether mhinduro icharatidza Newtonian fluid maitiro apo iyo yekumisikidza yakadzikira uye viscosity idiki kwazvo.Kana iyo yekuisa pfungwa ichiwedzera, mhinduro zvishoma nezvishoma inopa pseudoplastic fluid maitiro, uye iyo yakakwira iyo yekumisikidza, iyo inonyanya kuoneka iyo pseudoplastic.
