Cellulose ethers inopa yakanakisa viscosity kune yakanyorova dhaka, zvakanyanya kuwedzera kugona kwekubatanidza kwedhaka rakanyorova kune substrate uye inovandudza kusagirira kwedhaka, uye inoshandiswa zvakanyanya mukupurasa dhaka, zvidhinha kubatanidza dhaka uye ekunze masisitimu ekudzivirira.Iko kukora mhedzisiro ye cellulose ether inogona zvakare kuwedzera anti-kuparadzira kugona uye homogeneity yezvichangobva kusanganiswa zvinhu, kudzivirira zvinhu delamination, kupatsanurwa uye kuvharika kwemvura, uye inogona kushandiswa mufiber kongiri, pasi pemvura kongiri uye self-compacting kongiri.
Iko kukora kweiyo cellulose ethers pane simende zvinhu zvinobva kune viscosity ye cellulose ether solution.Pasi pemamiriro akafanana, iyo yakakwirira viscosity ye cellulose ether, zviri nani kutaridzika kweiyo yakagadziridzwa simende zvinhu, asi kana viscosity yakanyanya kukwira, inokanganisa kuyerera uye kushanda kwechinhu (semuenzaniso mapanga anonamira plaster).Madhaka ekuzvimisikidza uye anozvigadzirisa kongiri, izvo zvinoda kunyungudika kwemvura, zvinoda yakaderera viscosity ye cellulose ethers.Uye zvakare, iyo thickening mhedzisiro ye cellulose ethers inowedzera kudiwa kwemvura yesimende zvinhu uye inowedzera goho redhaka.
Iyo viscosity ye cellulose ether mhinduro inoenderana nezvinhu zvinotevera: molecular uremu hwe cellulose ether, concentration, tembiricha, shear rate uye nzira yekuyedza.Pasi pemamiriro akafanana, hukuru hwema molecular huremu hwe cellulose ether, iyo yakakwirira viscosity yemhinduro;iyo yakakwirira yekuisa, iyo yakakwira viscosity yemhinduro, mukushandiswa kwekutarisisa kunofanirwa kubhadharwa kuti udzivise dosing yakawandisa uye inokanganisa kushanda kwezvinhu zvedhaka nekongiri;cellulose ether solution viscosity inodzikira nekuwedzera kwekushisa, uye iyo yakakwira iyo yekumisikidza, iyo yakanyanya kufurira tembiricha;cellulose ether solution inowanzova pseudoplastic fluid, ine hunhu hwekuveura kuonda, iyo yakakura bvunzo Iyo yakakura yeshear rate yekuedzwa, iyo madiki viscosity, saka kubatanidzwa kwedhaka kuchaderedzwa pasi pekuita kwemasimba ekunze, iyo inobatsira pakuchera kuvaka kwedhaka, kuitira kuti dhaka rive nekushanda kwakanaka uye kubatana panguva imwe chete;nekuti iyo cellulose ether mhinduro isiri yeNewtonian fluid, iyo test viscosity bvunzo nzira, chiridzwa kana nharaunda yekuyedza, yakafanana cellulose ether mhinduro mhinduro inogona kusiyana zvakanyanya.
