Cellulose Ether- Ịkpụ na Ịkpụcha akpụ
Cellulose etherna-enye moto mmiri mmiri ezigbo viscosity, nke nwere ike ime ka njikọ dị n'etiti moto mmiri mmiri na oyi akwa ntọala dịkwuo mma, melite arụmọrụ mgbochi mmiri nke moto, a na-ejikwa ya nke ọma na moto plastering, moto njikọ taịlị seramiiki, na sistemụ mkpuchi mgbidi mpụta. Mmetụta siri ike nke cellulose ether nwekwara ike ime ka ikike mgbochi mgbasa na ịdị n'otu nke ihe ọhụrụ dịkwuo elu, ma gbochie nhazi ihe, nkewa, na nsị. Enwere ike iji ya maka simenti e ji eriri mee ka ọ sie ike, simenti mmiri dị n'okpuru mmiri, na simenti na-agbakọta onwe ya.
Mmetụta nke ime ka ọkpụrụkpụ nkecellulose etherna ihe ndị e ji simenti mee na-esi na viscosity nke ihe ngwọta cellulose ether pụta. N'otu ọnọdụ ahụ, viscosity dị elu nkecellulose ether, ka mma nke ihe ndị e ji simenti gbanwee. Agbanyeghị, ọ bụrụ na viscosity dị oke elu, ọ ga-emetụta ike na arụmọrụ nke ihe ahụ (dịka mma plastering). Sọọti nhazi onwe ya, simenti na-agbakọta onwe ya, wdg. chọrọ mmiri mmiri dị elu, viscosity nke cellulose ether dịkwa obere. Na mgbakwunye, mmetụta siri ike nke cellulose ether ga-emekwa ka mkpa mmiri nke simenti dịkwuo elu ma mee ka mmepụta nke simenti dịkwuo elu.
Mmiri mmiri nke cellulose ether dị elu nwere nnukwu thixotropy, nke bụkwa ihe e ji mara cellulose ether. Mmiri mmiri nke methyl cellulose na-enwekarị ihe ndị na-egosi mmiri pseudoplastic na nke na-abụghị thixotropic dị ala karịa okpomọkụ gel ya, mana ọ na-egosi mmiri Newtonian na obere nha nha. N'agbanyeghị ụdị na ogo nke nnọchi nke ihe ndị na-anọchi ya, pseudoplasticity na-abawanye ka mmụba nke ibu molekul ma ọ bụ mkpokọta nke cellulose ether. Ya mere, ọ bụrụhaala na ntinye na okpomọkụ na-adịgide, cellulose ethers nwere otu ọkwa viscosity (n'agbanyeghị MC,HPMC, Ụlọ ọrụ ahụike (HEMC)) na-egosipụta otu ihe ndị dị ka rheological mgbe niile. Mgbe okpomọkụ rịrị elu, gel nhazi na-etolite ma na-apụta nnukwu mmiri thixotropic.

Agbanyeghị, ka viscosity dị elu, otú ahụ ka ibu molekul nke cellulose ether dị elu, na mbelata kwekọrọ na ike ịgbaze ya. Ọ na-enwe mmetụta ọjọọ na njupụta na ike nhazi nke ngwa agha.
Cellulose Ether- Egbula oge
