1. Ịtọ oge
Cellulose ether nwere mmetụta azụ azụ na ngwa ngwa. Ka ọdịnaya nke cellulose ether na-abawanye, oge nhazi nke ngwa agha na-agbatịkwukwa. Mmetụta azụ azụ nke cellulose ether na ciment slurry na-adabere karịsịa n'ókè nke nnọchi nke alkyl, ọ dịghịkwa ihe jikọrọ ya na ịdị arọ ya. N'ókè nke ngbanwe nke alkyl dị ala, ka ọdịnaya hydroxyl na-abawanye, ma na-apụta ìhè karịa mmetụta azụ azụ. Ọzọkwa, na nnukwu ọdịnaya nke cellulose ether, ihe nkiri ihe nkiri dị mgbagwoju anya na-enwe mmetụta dị ịrịba ama na-egbu oge mmalite hydration nke ciment, ya mere, mmetụta nkwụsịtụ na-apụtakwa ìhè karị.

2.Bending ike na mkpakọ ike
Ọtụtụ mgbe, ike bụ otu n'ime ihe nleba anya dị mkpa maka ọgwụgwọ nke ihe simenti dabeere na ciment na ngwakọta. Mmụba nke ọdịnaya nke cellulose ether ga-ebelata ike mkpakọ na ike mgbanwe nke ngwa agha.

3. Bond ike
Cellulose ether nwere mmetụta dị ukwuu na arụmọrụ njikọ nke ngwa agha. Cellulose ether na-emepụta ihe nkiri polymer nwere mmetụta mkpuchi n'etiti cement hydration particles na usoro mmiri mmiri, nke na-akwalite mmiri dị ukwuu na ihe nkiri polymer n'èzí ciment ahụ, nke na-eme ka hydration zuru oke nke ciment, si otú ahụ meziwanye njikọ. ike nke slurry siri ike. N'otu oge ahụ, ihe kwesịrị ekwesị nke cellulose ether na-eme ka plasticity na mgbanwe nke ngwa agha dịkwuo elu, na-ebelata ike nke mpaghara mgbanwe n'etiti ngwa agha na ihe ntanetị, na-ebelata ikike mmịfe n'etiti oghere. Ruo n'ókè ụfọdụ, ọ na-eme ka mmetụta njikọ dị n'etiti ngwa agha na mkpụrụ. Tụkwasị na nke ahụ, n'ihi ọnụnọ cellulose ether na ciment slurry, a na-emepụta mpaghara mgbanwe pụrụ iche na interface oyi akwa n'etiti ngwongwo ngwa agha na ngwaahịa hydration. Nke a interface oyi akwa na-eme ka interface mgbanwe mpaghara ọzọ mgbanwe na obere isiike, si otú na-enye ngwa agha ike bonding ike.
