Iyo inozvimisa-leveling dhaka inogona kuvimba nehuremu hwayo kugadzira hwaro hwakati sandara, hwakatsetseka uye hwakasimba pane substrate yekuisa kana kubatanidza zvimwe zvinhu. Panguva imwecheteyo, inogona kuita yakakura uye inobudirira kuvaka. Naizvozvo, kunyungudika kwemvura kwakakosha zvakanyanya kwedhaka rekuzvimiririra Mukuwedzera, inofanirwa kunge iine kumwe kuchengetedza kwemvura uye kusimba kwechisungo, pasina kupatsanurwa kwemvura chiitiko, uye kuve nehunhu hwekudzivirira kupisa uye kuderera kwekushisa kukwira.
Kazhinji, dhaka rekuzvimisikidza rinoda mvura yakanaka. Cellulose ether ndiyo inonyanya kuwedzera yedhaka yakasanganiswa. Kunyangwe iyo mari yakawedzerwa yakaderera kwazvo, inogona kuvandudza zvakanyanya kuita kwedhaka. Inogona kuvandudza kuwirirana, kushanda uye kusungirirwa kwedhaka. kushanda uye kuchengetedza mvura. Inoita basa rinokosha zvikuru mumunda wedhaka rakagadzirwa rakagadzirwa.
Cellulose ether ine pesvedzero yakakosha pakuchengetedza mvura, kuenderana uye kuita kwekuvaka kweanozvigadzirisa dhaka. Kunyanya sedhaka rekuzvimisa-leveling, fluidity chimwe chezviratidzo zvikuru zvekuongorora kuzvidzora kuita. Pasi pemamiriro ekuvimbisa kuumbwa kwakajairika kwedhaka, iyo fluidity yedhaka inogona kugadziriswa nekushandura huwandu hwe cellulose ether. Zvisinei, kana muyero wacho wakanyanya kukwirira, kunyunguduka kwedhaka kuchaderedzwa, saka chiyero che cellulose ether chinofanira kudzorwa mukati mehutano hunonzwisisika.
Kuchengetwa kwemvura kwedhaka indekisi yakakosha yekuyera kugadzikana kwezvikamu zvemukati zvezvichangobva kusanganiswa sement mortar. Kuti uite zvizere hydration reaction yeiyo gel zvinhu, inonzwisisika huwandu hweselulosi ether inogona kuchengetedza mwando mudhaka kwenguva yakareba. Kazhinji kutaura, mwero wekuchengetedza mvura weslurry unowedzera nekuwedzera kwe cellulose ether yemukati. Kuchengetedza kwemvura kweselulosi ether kunogona kudzivirira iyo substrate kuti isatore mvura yakawandisa nekukurumidza, uye inotadzisa kubuda kwemvura, kuitira kuti ive nechokwadi chekuti slurry nharaunda inopa mvura yakakwana yesamende hydration. Mukuwedzera, iyo viscosity ye cellulose ether inewo simba guru pakuchengetedza mvura kwedhaka. Iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Kazhinji, cellulose ether ine viscosity ye400mpa.s inonyanya kushandiswa mumatope ekuzvimisa, izvo zvinogona kuvandudza kushanda kwedhaka uye kuwedzera kuwirirana kwedhaka.
