Mudhaka, cellulose ether inoita basa rekuchengetedza mvura, kukora, kunonoka simende hydration simba, uye kunatsiridza mashandiro ekuvaka. Yakanaka kuchengetedza mvura inoita kuti simende hydration iwedzere kuzara, inogona kuvandudza yakanyorova viscosity yedhaka rakanyorova, kuwedzera simba rekubatanidza redhaka, uye kugadzirisa nguva. Kuwedzera cellulose ether kune mechanic yekupfapfaidza dhaka kunogona kuvandudza kupfapfaidza kana kupomba kuita uye kusimba kwechimiro chedhaka. Cellulose inoshandiswa zvakanyanya sechinhu chakakosha chekuwedzera mune yakagadzirira-yakasanganiswa dhaka. Tichitora ndima yezvivakwa zvekuvaka semuenzaniso, cellulose ether ine yakanakisa zvivakwa zvakaita sekukora, kuchengetedza mvura, uye kunonoka. Naizvozvo, kuvaka giredhi cellulose ether inoshandiswa zvakanyanya kuvandudza kugadzirwa kwedhaka rakagadzirwa-yakasanganiswa (kusanganisira yakanyorova-yakasanganiswa dhaka uye yakaoma-yakasanganiswa dhaka), PVC resin, nezvimwewo, latex pendi, putty, nezvimwewo, kusanganisira kuita kwe kuvaka zvinhu zvigadzirwa.
Cellulose inogona kunonoka hydration process ye simenti. Cellulose ether inoisa dhaka nezvinhu zvakasiyana-siyana zvinobatsira, uye zvakare inoderedza kupisa kwekutanga kwe hydration ye simenti uye kunonotsa hydration dynamic process ye simenti. Izvi hazvina kunaka pakushandiswa kwedhaka munzvimbo dzinotonhora. Uku kudzoreredza mhedzisiro kunokonzerwa nekushambadza kwe cellulose ether mamorekuru pane hydration zvigadzirwa seCSH uye ca(OH)2. Nekuda kwekuwedzera kweiyo viscosity yemushonga wepore, iyo cellulose ether inoderedza kufamba kweiyoni mumhinduro, nekudaro kunonoka hydration process. Iyo yakanyanya kukwirisa iyo cellulose ether mumineral gel zvinhu, zvakanyanya kutaurwa mhedzisiro yekunonoka kwe hydration. Cellulose ether haingononotse kumisa, asiwo inononoka kuomeswa kwesimende mortar system. Iko kudzoreredza mhedzisiro ye cellulose ether kunoenderana kwete chete nekuisa kwayo mumineral gel system, asiwo pane chimiro chemakemikari. Iyo yakakwirira dhigirii yemethylation yeHEMC, zviri nani kudzoreredza mhedzisiro ye cellulose ether. Chiyero che hydrophilic substitution kune mvura-inowedzera kutsiva Iyo yekudzosa mhedzisiro yakasimba. Nekudaro, iyo viscosity ye cellulose ether haina mhedzisiro pasimende hydration kinetics.
Nekuwedzera kwezvinyorwa zve hydroxypropyl methyl cellulose ether, nguva yekugadzika yedhaka inowedzera zvakanyanya. Pane yakanaka isina mutsara kuwirirana pakati pekutanga kugadzika nguva yedhaka uye zviri mukati cellulose ether, uye yakanaka mutsara kuwirirana pakati pekupedzisira kuseta nguva uye zviri mukati cellulose ether. Tinogona kudzora nguva yekushanda kwedhaka nekushandura huwandu hwe cellulose ether.
