1.Kukhazikitsa nthawi
Ma cellulose ether ali ndi vuto linalake lochepetsa matope. Pamene zomwe zili mu cellulose ether zikuwonjezeka, nthawi yoyika matope imatalika. Kuchedwetsa kwa cellulose etha pa slurry ya simenti makamaka kumadalira kuchuluka kwa m'malo mwa alkili, ndipo sikukhudzana kwambiri ndi kulemera kwake. Kutsika kwa ma alkyl m'malo, kumapangitsa kuti hydroxyl ikhale yochulukirapo, komanso kuchedwetsa kowonekera. Kuphatikiza apo, ndi kuchuluka kwa cellulose ether, filimu yovuta kwambiri imakhala ndi zotsatira zochulukirapo pakuchedwetsa ma hydration oyambirira a simenti, motero, kubweza kumakhalanso koonekeratu.

2.Kupiringa mphamvu ndi compressive mphamvu
Nthawi zambiri, mphamvu ndi chimodzi mwazofunikira zowunikira pakuchiritsa kwa zinthu zopangira simenti zosakaniza. Kuwonjezeka kwa zomwe zili mu cellulose ether zidzachepetsa mphamvu yopondereza ndi mphamvu yosinthasintha ya matope.

3. Mphamvu ya mgwirizano
Cellulose ether imakhudza kwambiri kugwirizana kwa matope. Ma cellulose ether amapanga filimu ya polima ndi kusindikiza pakati pa simenti ya hydration particles mu dongosolo lamadzimadzi, lomwe limalimbikitsa madzi ambiri mu filimu ya polima kunja kwa particles za simenti, zomwe zimathandiza kuti hydration yathunthu ya simenti ikhale yabwino, potero kuwongolera mgwirizano. mphamvu ya slurry wowuma. Pa nthawi yomweyi, kuchuluka koyenera kwa cellulose ether kumawonjezera pulasitiki ndi kusinthasintha kwa matope, kuchepetsa kusasunthika kwa malo osinthika pakati pa matope ndi mawonekedwe a gawo lapansi, ndi kuchepetsa kutsetsereka kwa mphamvu pakati pa mawonekedwe. Kumbali ina, kumawonjezera mgwirizano pakati pa matope ndi gawo lapansi. Komanso, chifukwa cha kukhalapo kwa mapadi efa mu slurry simenti, wapadera mawonekedwe kusintha zone ndi mawonekedwe wosanjikiza aumbike pakati pa matope particles ndi mankhwala hydration. Izi mawonekedwe wosanjikiza zimapangitsa mawonekedwe kusintha zone kusinthasintha ndi zochepa okhwima, motero kupereka matope amphamvu chomangira mphamvu.
