Mumortar, cellulose ether inoita basa rekuchengetedza mvura, kukora, kunonotsa simba remvura yesimende, uye kuvandudza mashandiro ekuvaka. Kugona kwakanaka kwekuchengetedza mvura kunoita kuti hydration yesimende ive yakakwana, kunogona kuvandudza kunyorova kwemortar yakanyorova, kuwedzera simba rekubatanidza mortar, uye kugadzirisa nguva. Kuwedzera cellulose ether mumortar yekupfapfaidza yemakanika kunogona kuvandudza mashandiro ekupfapfaidza kana kupomba uye simba rechimiro chemortar. Cellulose inoshandiswa zvakanyanya sechinhu chakakosha mumortar yakasanganiswa yakagadzirwa. Tichitora munda wezvinhu zvekuvaka semuenzaniso, cellulose ether ine hunhu hwakanaka hwakadai sekukora, kuchengetedza mvura, uye kunonoka. Naizvozvo, cellulose ether yemhando yezvivakwa inoshandiswa zvakanyanya kuvandudza kugadzirwa kwemortar yakasanganiswa yakagadzirwa (kusanganisira mortar yakasanganiswa yakanyorova uye dry-mixed mortar), PVC resin, nezvimwewo, latex pendi, putty, nezvimwewo, kusanganisira mashandiro ezvigadzirwa zvekuvaka.
Cellulose inogona kunonotsa maitiro emvura esimende. Cellulose ether inopa mudhaka zvinhu zvakasiyana-siyana zvinobatsira, uye inoderedzawo kupisa kwekutanga kwemvura yesimende uye inononotsa maitiro emvura nesimende. Izvi hazvina kunaka kushandiswa kwemudhaka munzvimbo dzinotonhora. Mhedzisiro iyi yekunonoka inokonzerwa nekunyungudika kwemamorekuru e-cellulose ether pazvigadzirwa zvemvura zvakaita seCSH neca(OH)2. Nekuda kwekuwedzera kwe viscosity yemushonga wepore, mudhaka we cellulose ether unoderedza kufamba kwemaion mumushonga, nokudaro uchinonotsa maitiro emvura. Kana huwandu hwe cellulose ether mu mineral gel material, mhedzisiro yekunonoka kwemvura inowedzera. Mudhaka we Cellulose haungononotsi chete, asiwo unononotsa maitiro ekusimbisa simende. Mhedzisiro yekunonoka kwe cellulose ether haingotsamiri pakuwanda kwayo mu mineral gel system, asiwo pachimiro chemakemikari. Kana mwero we methylation yeHEMC wakakwira, mhedzisiro yekunonoka kwe cellulose ether inowedzera. Chiyero chekutsiva hydrophilic kune kuwedzera kwemvura Mhedzisiro yekunonoka inowedzera. Zvisinei, viscosity ye cellulose ether haina simba guru pa hydration ye simende.
Nekuwedzera kwehuwandu hwehydroxypropyl methylcellulose ether, nguva yekuiswa kwemota yakawedzera zvakanyanya. Pane hukama hwakanaka husina kurongeka pakati penguva yekutanga yekuiswa kwemota nehuwandu hwecellulose ether, uye hukama hwakanaka pakati penguva yekupedzisira yekuiswa uye huwandu hwecellulose ether. Tinogona kudzora nguva yekushanda kwemota nekuchinja huwandu hwecellulose ether.
