Methylcellulose

Methyl cellulose, nke akpọrọ MC, nke a makwaara dị ka cellulose methyl ether, bụ ether cellulose nonionic. Ọ nwere ọdịdị nke ọcha, odo odo ma ọ bụ ntụ ntụ ntụ ntụ, granular ma ọ bụ fibrous, na-esi ísì ụtọ, enweghị ụtọ, na-adịghị egbu egbu na nke na-adịghị ewe iwe, hygroscopic.

Methylcellulose bụ soluble n'ime glacial acetic acid, mana ọ naghị esiri ya ike na ihe mgbaze organic dị ka ethanol, ether, acetone, na chloroform. Methylcellulose nwere mmetụta gel dị iche iche. Mgbe agbazere na mmiri ọkụ karịa 50ºC, ọ nwere ike gbasaa ngwa ngwa wee zaa ka ọ bụrụ gel. Mgbe okpomọkụ mmiri dara n'okpuru 50 Celsius, ọ ga-agbaze n'ime mmiri iji mepụta ngwọta mmiri. Ngwọta mmiri na ụdị gel nwere ike ịmekọrịta ibe ha.

Nkwadebe nke methyl cellulose na-eji eke cellulose dị ka owu pulp na osisi pulp dị ka akụrụngwa, na-emeso ya na alkali (dị ka sodium hydroxide, wdg) iji nweta alkali cellulose, na mgbe etherified site n'ịgbakwụnye methyl chloride. Mmeghachi omume na a ụfọdụ okpomọkụ, mgbe na-asachapụ, neutralization, akpịrị ịkpọ nkụ, ihicha na ndị ọzọ Filiks, dị ka ngwaahịa dị ọcha na teknuzu ọdịnaya, methyl cellulose nwere ike kewara pharmaceutical ọkwa methyl cellulose, nri ọkwa methyl cellulose, izugbe-nzube methyl cellulose na ndị ọzọ na ngwaahịa. .

Methylcellulose na-eguzogide acid na alkalis, mmanụ, okpomọkụ, microorganisms na ìhè. Ọ nwere ezigbo mkpụkọ, imepụta ihe nkiri, na-ejigide mmiri, emulsifying, wetting, dispersing, and nrapado Njirimara.

Methylcellulose nwere ọtụtụ ngwa dị n'okpuru ala, site na mkpuchi, inks, nrapado ruo akwa akwa, ibipụta na ịcha akwa na ọgwụ na nhazi nri. Ọtụtụ ụlọ ọrụ nwere ngwa chọrọ maka ngwaahịa ma nwee ohere mmepe sara mbara. Mgbe ogologo oge na-aga n'ihu na-aga n'ihu, ụlọ ọrụ methyl cellulose nke obodo m etolitela ọnụ ọgụgụ ụfọdụ, na ngwaahịa ngwaahịa na-aghọwanye nke zuru oke, ma ọ dị mkpa ka ọ dịkwuo mma n'ihe gbasara ọnụ ọgụgụ na mmepe zuru oke!
