Usoro na-arụpụta usoro nke sodium cardixyylcellose

Usoro na-emepụta usoro nke sodium carnoxyylcellose (cmc) na-agụnye ọtụtụ usoro, gụnyere ịkwadebe nke mkpụrụ osisi cellulose, ehurtification, na nkụ. Nke a bụ nyocha nke usoro nrụpụta ahụ:

1. Nkwadebe nke cellulose: Usoro a na-amalite site na nkwadebe nke cellulose, nke a na-ejikarị ahịhịa purp ma ọ bụ akwa akwa. A na-ebu ụzọ mee cellose ma nụchaa iwepu adịghị ọcha dịka liminin, Hemicelllose, na ihe ndị ọzọ. Celdilose a dị ọcha na-arụ ọrụ dị ka ihe mbido maka mmepụta nke cmc.
2. Alkalization: A na-emeso cellulose dị ọcha na ngwọta alkaline, na-abụkarị sodium hydroxide (NaOh), iji mee ka mmeghachi omume ya na-esote. Alkalization na-enyere aka ịza ma mepee eriri cellulose, na-eme ka ha nwekwuo ohere ịnweta kemịkal.
3. Mmeghachi omume eality: cellulose na-emeghachi omume na monochlorocetic acid (mca) ma ọ bụ nnu ya nnu, sodium modechlorotetetate (SMCA), n'ihu onye na-ahụ maka ihe na-achịkwa. Ihe mmeghachi omume nke ihe eji emejupụta na-agụnye nnọchi nke otu hydroxy na ụdị cellulose na carksyyyyyyyyyyyyyyyyyyyymythythyl (-ch2Coona) otu. Enwere ike ịchịkwa ogo (DS), nke na-anọchite ọnụ ọgụgụ nke otu nke counteryyl site na idozi ọnọdụ mmeghachi omume dị ka okpomọkụ, oge mmeghachi omume, yana itinye uche.
4. Nnọpụiche: Mgbe mmeghachi omume ahụ gasịrị, ngwaahịa a na-esiteghị na-agbanwe agbanwe na-agbanwe ndị acidic sochiri anya sodium sodium ha (corboxymethlcelllose). A na-enweta nke a site na ịgbakwunye usoro alkaline, dịka sodium hydroxide (NaOh), na ngwakọta mmeghachi omume. Neutralization na-enyere aka idozi PH nke ngwọta ahụ ma dozie ngwaahịa CMC.
5. A na-asacha sodium cardexyyyyyylclose bụ mgbe ahụ ka ọ dị ọcha iji wepu adịghị ọcha, ndị na-enweghị atụ, na site na ngwakọta mmeghachi omume. Fliceszọ dị ọcha nwere ike ịgụnye ịsachasị, nzacha, centrifgation, na ihicha. A na-ejikarị cmc dị ọcha na-asacha alkali na nnu, na-esochi ya site na nzacha ma ọ bụ centrifugation kewapụ ngwaahịa cmC siri ike site na mmiri mmiri.
6. Akpukpo: Ahịhịa sodium dị ọcha na-emesịa kpọnwụọ iji wepu oke mmiri ma nweta ihe achọrọ mmiri maka nchekwa na nhazi ọzọ. Mechie usoro nwere ike ịgụnye ihicha ikuku, fesa nkụ, ma ọ bụ nkụ, na-adabere na njirimara ngwaahịa na usoro nrụpụta chọrọ.

Ngwaahịa sodium na-arụpụta sodiumylcellyylcellose bụ ntụ ọcha na-acha ọcha ma ọ bụ ihe dị ọcha nwere ezigbo mmiri sol na nsị rdeuloulo. A na-ejikarị ya dị ka onye na-ahụ maka ya dị ka ihe na-eme ka ọ bụrụ onye na-eme mkpọtụ, mgbochi, na ndagwurugwu, gụnyere nri ọgwụ, ọgwụ na ngwa.
