1.Kuisa nguva
Cellulose ether ine kumwe kudzoreredza mhedzisiro padhaka. Sezvo zviri mukati me cellulose ether zvinowedzera, nguva yekugadzika yedhaka inowedzerawo. Kudzoreredza mhedzisiro ye cellulose ether pane simende slurry zvakanyanya zvinoenderana nehuwandu hwekutsiviwa kwealkyl, uye haina hukama hwepedyo nehuremu hwayo hwemamorekuru. Iyo yakaderera dhigirii yealkyl inotsiva, iyo yakakura iyo hydroxyl yemukati, uye zvakanyanya kujeka mhedzisiro yekudzosa. Uyezve, nehuwandu hwehuwandu hwe cellulose ether, iyo yakaoma firimu layer ine mhedzisiro yakakosha pakunonoka kwekutanga hydration ye simenti, saka, kudzoreredza mhedzisiro kunonyanya kuoneka.

2.Bending simba uye compressive simba
Kazhinji, simba ndechimwe chezvakakosha zviratidziro zvekurapa kwesement-based simenti zvinhu pamisanganiswa. Kuwedzera kwemukati we cellulose ether kunoderedza kusimba kwesimba uye flexural simba redhaka.

3. Bond simba
Cellulose ether ine simba guru pakushanda kwekubatanidza kwedhaka. Cellulose ether inoumba firimu repolymer rine chisimbiso pakati pesimende hydration zvimedu mune yemvura chikamu system, iyo inosimudzira huwandu hwemvura mupolymer firimu kunze kwemasimende masimende, ayo anobatsira kune yakazara hydration ye simenti, nekudaro kuvandudza kusungirirwa. simba rekuoma kweslurry. Panguva imwecheteyo, chiyero chakakodzera che cellulose ether chinowedzera purasitiki uye kushanduka kwevhu, kuderedza kusimba kwenzvimbo yekushandura pakati pedhaka uye substrate interface, uye kuderedza kukwanisa kutsvedza pakati penzvimbo. Kusvika kumwero wakati, inosimudzira mubatanidzwa pakati pedhaka uye substrate. Uye zvakare, nekuda kwekuvapo kwe cellulose ether mune simende slurry, yakakosha interface yekushandura zone uye interface layer inoumbwa pakati pemateki evhu uye hydration zvigadzirwa. Iyi interface layer inoita kuti interface yekushandura nzvimbo iwedzere kuchinjika uye kushomeka, nekudaro ichipa dhaka rakasimba rekubatanidza simba.
