Celloxythythythythythythythylythym cellulose (cmc) bu polymer na-ejikarị ọtụtụ ọrụ, ọgwụ, ihe ịchọ mma, akwụkwọ na mmanụ. A na-enweta ya site na ntụgharị kemịkal nke cellulose. Ihe eji eme ihe eji eme ya bu na ndi otu hydroxy na celloxyyyyyyyyyyyyyyyym) na sodium na sodium na-eji sodium na-anọchi ya.
1. Ihe owuwu kemịkalụ na akụrụngwa
Usoro kemịkal nke sodium celloxythym cellulose bụ (c6h7o2 (oh) 2ch2coona) n, nke nwere ikike na mmiri. Ihe nhazi ya bụ ihe eji emepụta eriri afọ nke cellulose monomers-glucose molecules. Mgbe mgbanwe kemịkal, ụfọdụ ma ọ bụ niile ma ọ bụ akụkụ hydroxy na cellulose modecuse modecuse na carloxyyyylyyl na-edochi molecules soluble na-acha uhie uhie. Kpamkpam, akwara ụmụ sodium celloxythythythythythythyyyyyyyyyyyyyyyl, na-enye ya ezigbo solicosis na njiri mara.
CMC nwere ihe ndị na-esonụ:
Enwere ike ịgbasa mmiri sodium na-agbaze ngwa ngwa na mmiri iji mepụta ngwọta colloidal.
Visatydị viscosity: Ngwọta Mem dị elu nwere viscosity dị elu, na viscosis na ogo molecular ya na ntinye uche ya.
Ike: cmc nwere ezigbo nkwụsi ike na acid, alkali na elu okpomọkụ, mana na acid ma ọ bụ alkali gburugburu, nkwụsi ike nke cmc ga-ebelata.
Nhazi: Site na ịhazigharị molecular ogo molecular nke cmc, enwere ike ịchịkwa ihe ndị ahụ na kemịkal ya.
2. Usoro Nkwadebe Nkwadebe
Sodium carboxymethyl cellulose is usually prepared by reacting cellulose and sodium chloroacetate in an alkaline environment. Usoro ahụ akọwapụtara dị ka ndị a:
A na-asatrutement nke cellulose: mbụ, cellulose (dị ka eriri abara) iji wepu adịghị ọcha.
Mmeghachi omume Alkalintation: Celltenalization na-eme emeghachi omume na sodium hydroxide a ga-ekewa hydroxy akụkụ akwara mkpụrụ osisi cellulose na-arụ ọrụ na-arụ ọrụ.
A na-etinye mmeghachi omume:
Washing and drying: After the reaction is completed, the product is washed with water to remove impurities, and finally purified sodium carboxymethyl cellulose is obtained.
3. Ugbo ala
N'ihi ezigbo mmiri mmiri, na-eto ma kwụsie ike, na-eji celloxythythythythythylythyl na-ejikarị ubi ndị a:
Industrylọ ọrụ nri: dị ka nke na-eme nke ọma, kwụsie ike, sie ike, na-aga n'ihu, well, na-arụ ọrụ, wdg.
Industrylọ ọrụ ọgwụ: dị ka ihe mgbochi, na-ejide onwe ya, a na-egbochi onye nnọchi anya ọgwụ, a na-eji ya na mbadamba, ihe ọ bụla, mmanụ na nkwadebe ndị ọzọ. Na mgbakwunye, a na-eji cmc mee ihe dị ka ihe omimi maka ịwa ahụ na nke eze.
Industrylọ ọrụ ịchọ mma: Ejiri ya na mmepụta nke lotions, ude, shampoos, ezé na ngwaahịa ndị ọzọ dị ka ndị ọzọ na-agbaze. Ọ nwere ike idozi viscosity nke ngwaahịa ma kwalite ahụmịhe onye ọrụ.
Industrylọ ọrụ na-eme mkpọtụ: Dịka onye na-ahụ maka nchekwa dị elu maka akwụkwọ, cmc nwere ike imeziwanye ike, mmiri na-eguzogide na mbipụta nke akwụkwọ ma belata uzuzu n'elu akwụkwọ.
A na-eji mkpọnwụ mmanụ: Mgbe a na-eji ihe na-egwu mmiri, a na-eji cmc na mmiri mmiri iji mee ka mmiri gwuo mmiri, na-enyere aka wepu okwute na-agba gburugburu mgbidi ahụ.
Industrylọ ọrụ stutgery: Dika onye na - anyụ ọgwụ na - ebido mado, cmc nwere ike ime ka mkpụrụ edemede na ogo dị mma.
4. Nchekwa na mmetụta gburugburu
Sodium carboxymethyl cellulose is generally considered safe, and its use in food and medicine has been approved by the International Food Additives Codex and relevant regulations of many countries. Ọ bụ ahụ mmadụ anaghị egbu egbu ma ọ gaghị enwe mmetụta dị ukwuu na gburugburu ebe obibi gburugburu, yabụ na-eji ya.
Agbanyeghị, ọ bụ ezie na CMC n'onwe ya bụ gburugburu ebe obibi, usoro ọgwụgwọ ya nwere ike ịgụnye iji ihe ụfọdụ ndị na-ede ihe na-eme ihe nkiri na ihe ndị a na-enweta na ihe ndị a na-eme ka ihe nkiri. Ya mere, ọ dị mkpa ị attentiona ntị na ihe nchebe gburugburu ebe obibi n'oge usoro imepụta iji belata ọpụpụ nke ihe na-emerụ ahụ.
Celloxyythythythythythylythym cellulose bụ ihe eji eme polymertal. Ngwongwo ya na - edozi ya na ihe na - eme ka ọ dị mkpa maka ọtụtụ ụlọ ọrụ. Site na nri, ọgwụ na ụlọ ọrụ, cmc na-arụ ọrụ dị mkpa. Site na oganihu nke teknụzụ n'ọdịniihu, enwere ike ịbawanye ngwa ngwa CMC.
