Cellulose ether nwere mmetụta ụfọdụ na-egbochi ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-adịghị mma. Ka ọnụọgụgụ cellulose ether na-abawanye, oge ntọala nke ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-adịghị mma na-agbatịkwu. Mmetụta nke cellulose ether na ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-adịghị mma dabere na oke nnọchi nke otu alkyl, ebe ọ nweghị ihe jikọrọ ya na ibu molekul ya.
Ka oke nke alkyl gbanwere obere, otú ahụ ka ọdịnaya hydroxyl ga-esi buru ibu, otú ahụ ka mmetụta nke cellulose ether ga-esi pụta ìhè. Ka oke nke cellulose ether si dị, otú ahụ ka mmetụta nke ihe nkiri dị mgbagwoju anya na-ebelata n'oge mmiri simenti na-amalite ịpụta ìhè, otú ahụ ka mmetụta nke ihe nkiri ahụ na-ebelatakwa ìhè.
Ike bụ otu n'ime ihe ndị dị mkpa e ji enyocha ihe ndị e ji simenti mee na-agwọ ọrịa na ngwakọta ahụ. Mgbe ọnụọgụgụ nke cellulose ether mụbara, ike nrụgide na ike flexural nke mortar ga-ebelata. Ike njikọ siri ike nke mortar simenti agwakọtara na cellulose ether na-aka mma; Ike flexural na compressive nke mortar simenti na-ebelata, ka ọnụọgụgụ ahụ na-akawanye njọ, otú ahụ ka ike ahụ na-ebelata;
Mgbe agwakọtara hydroxypropyl methyl cellulose ether, ka usoro onunu ogwu ahụ na-abawanye, ike mgbagọ nke simenti na-ebu ụzọ na-abawanye ma na-ebelata, ike nrụgide ahụ na-ebelatakwa nwayọ nwayọ. Ekwesịrị ijikwa usoro onunu ogwu kachasị mma na 0.1%.
Cellulose ether nwere nnukwu mmetụta na arụmọrụ njikọ nke ngwa agha. Cellulose ether na-emepụta ihe nkiri polymer nke nwere mmetụta mkpuchi n'etiti ihe ndị na-eme ka simenti dị na sistemụ mmiri mmiri, nke na-akwalite mmiri ka ukwuu na ihe nkiri polymer n'èzí ihe ndị na-eme ka simenti dị ọcha, nke na-eme ka simenti ahụ dị ọcha kpamkpam, si otú a na-eme ka ike njikọ nke ihe ahụ dị mma mgbe ọ gbasiri ike.
N'otu oge ahụ, ọnụọgụgụ cellulose ether kwesịrị ekwesị na-eme ka plasticity na mgbanwe nke moto ahụ dịkwuo mma, na-ebelata ike nke mpaghara mgbanwe dị n'etiti moto na substrate interface, ma na-ebelata ikike ịmịgharị n'etiti njikọ. Ruo n'ókè ụfọdụ, mmetụta njikọ dị n'etiti moto na substrate na-eme ka ọ dịkwuo mma.
Na mgbakwunye, n'ihi ọnụnọ nke cellulose ether na simenti, a na-emepụta mpaghara mgbanwe interface pụrụ iche na oyi akwa interface n'etiti ihe ndị e ji agwakọta moto na ngwaahịa mmiri mmiri. Oyi akwa interface a na-eme ka mpaghara mgbanwe interface dịkwuo mfe ma ghara isi ike. Ya mere, ọ na-eme ka moto ahụ nwee ike njikọ siri ike.
