The MC eji maka akọrọ ntụ ntụ ngwa agha chọrọ ka ntụ ntụ, na obere mmiri ọdịnaya, na fineness na-achọkwa 20% ~ 60% nke urughuru size na-erughị 63um. Ịdị mma na-emetụta solubility nke methyl cellulose ether. Nnukwu MC na-adịkarị n'ụdị granules, ọ dịkwa mfe igbari n'ime mmiri na-enweghị agglomeration, mana ọnụego mgbasa na-adị ngwa ngwa, n'ihi ya, ọ naghị adabara iji mee ihe na ntụ ntụ ntụ.
N'ime ngwa ngwa ntụ ntụ akọrọ, MC na-agbasasị n'etiti mkpokọta, ezigbo ihe na-ejuputa na ciment na ihe ciment ndị ọzọ. Naanị ezigbo ntụ ntụ nwere ike izere methyl cellulose ether agglomeration mgbe ị na-agwakọta mmiri. Mgbe MC na-agbakwunyere mmiri iji gbazee agglomerates, ọ na-esiri ike ịgbasa na igbari. Oke MC abụghị naanị ihe efu, kamakwa ọ na-ebelata ike mpaghara nke ngwa agha ahụ. Mgbe a na-etinye ụrọ ntụ ntụ dị otú ahụ n'ebe buru ibu, a ga-ebelata ọsọ ọsọ nke ntụ ntụ ntụ ntụ dị n'ógbè ahụ, na mgbawa ga-apụta n'ihi oge ọgwụgwọ dị iche iche. Maka igwe a na-efesa ngwa agha na-arụ ọrụ, n'ihi obere oge ịgwakọta, ihe a chọrọ maka ịdị mma dị elu.
Ịdị mma nke MC na-emetụtakwa njigide mmiri ya. N'ikwu okwu n'ozuzu, maka methyl cellulose ethers nwere otu viscosity mana ịdị mma dị iche iche, n'okpuru otu ego agbakwunyere, nke kachasị mma na-eme ka mmetụta njide mmiri dịkwuo mma.
Njide mmiri nke MC na-ejikọta ya na okpomọkụ ejiri mee ihe, na njide mmiri nke methyl cellulose ether na-ebelata na mmụba nke okpomọkụ. Tinyere na ihe ndị na-ekpo ọkụ n'okpuru ọnọdụ okpomọkụ dị elu iji mee ngwangwa ọgwụgwọ ciment na hardening nke akọrọ ntụ ntụ ngwa agha. Mbelata nke njide mmiri na-eduga na mmetụta nke ịrụ ọrụ na nkwụsị mgbawa, ọ na-aghọkwa ihe dị mkpa iji belata mmetụta nke ihe okpomọkụ n'okpuru ọnọdụ a.
Ọ bụ ezie na a na-ewere ihe mgbakwunye methyl hydroxyethyl cellulose ether ugbu a dị ka ndị na-ebute ụzọ na mmepe nkà na ụzụ, ndabere ha na okpomọkụ ka ga-eduga n'ịda mbà nke arụmọrụ nke akọrọ ntụ ntụ ntụ. Site na ụfọdụ ọgwụgwọ pụrụ iche na MC, dị ka ịba ụba nke etherification, wdg, enwere ike ịnọgide na-enwe mmetụta njigide mmiri na okpomọkụ dị elu, ka o wee nwee ike inye ọrụ ka mma n'okpuru ọnọdụ siri ike.
