Carboxymethyl Cellulose (CMC) bụ ihe dị mkpa e ji eme polima mmiri na-agbaze nke a na-ejikarị eme ihe n'ihe gbasara nri, ọgwụ, kemịkalụ kwa ụbọchị, ákwà na ihe ndị ọzọ. N'ụlọ ọrụ nri, otu n'ime ihe kachasị mkpa e ji eme ihe na CMC bụ ihe na-eme ka ihe dị arọ. Ihe ndị na-eme ka ihe dị arọ bụ otu ihe mgbakwunye nke na-eme ka mmiri dị nro karịa n'enweghị mgbanwe nke ukwuu n'ihe ndị ọzọ dị na mmiri ahụ.
1. Usoro nhazi kemịkalụ na ụkpụrụ nke carboxymethyl cellulose
Carboxymethylcellulose bụ ihe sitere na cellulose nke e mepụtara site na iji otu carboxymethyl (-CH2COOH) dochie akụkụ nke otu hydroxyl (-OH) nke cellulose. Isi ihe owuwu ya bụ usoro β-D-glucose na-emegharị ugboro ugboro. Mwebata nke otu carboxymethyl na-enye CMC hydrophilicity, na-enye ya ezigbo mgbaze na ikike ime ka ọ sie ike na mmiri. Ụkpụrụ ime ka ọ sie ike dabere na isi ihe ndị a:
Mmetụta nke ọzịza: CMC ga-aza mgbe ọ mịkọrọ molekul mmiri n'ime mmiri, na-emepụta nhazi netwọk, nke mere na a ga-ejide molekul mmiri n'ime nhazi ya, na-eme ka viscosity nke sistemụ ahụ dịkwuo elu.
Mmetụta chajị: A ga-etinye otu carboxyl dị na CMC n'ime mmiri iji mepụta chajị na-adịghị mma. Otu chajị ndị a ga-emepụta ihe mgbochi electrostatic na mmiri, na-eme ka agbụ molekul gbasaa ma mepụta ihe ngwọta nwere oke viscosity.
Ogologo na ntinye nke agbụ ígwè: Ogologo na ntinye nke agbụ ígwè nke molekul CMC ga-emetụta mmetụta ya na-eme ka ọ sie ike. N'ikwu ya n'ozuzu, ka ibu molekul dị elu, otú ahụ ka viscosity nke ngwọta ahụ si dịkwuo elu; n'otu oge ahụ, ka ntinye nke ngwọta ahụ si dị elu, otú ahụ ka viscosity nke sistemụ ahụ na-abawanye.
Njikọta molekul: Mgbe CMC gbazere n'ime mmiri, n'ihi njikọ dị n'etiti molekul na nhazi nke usoro netwọk, molekul mmiri na-anọkarị n'ebe ụfọdụ, na-ebute mbelata na mmiri mmiri nke ngwọta ahụ, si otú a na-egosi mmetụta siri ike.
2. Ojiji nke carboxymethyl cellulose n'ime ụlọ ọrụ nri
N'ụlọ ọrụ nri, a na-ejikarị carboxymethylcellulose eme ihe dị ka ihe na-eme ka ihe sie ike. Ihe ndị a bụ ụfọdụ ihe atụ nke ojiji a na-ejikarị eme ihe:
Ihe ọṅụṅụ na ihe ndị e ji mmiri ara ehi mee: N'ime ihe ọṅụṅụ mkpụrụ osisi na ihe ọṅụṅụ lactobacillus, CMC nwere ike ime ka ihe ọṅụṅụ ahụ dịkwuo mma, melite uto ya ma mee ka ndụ ya dịkwuo ogologo. Karịsịa na ngwaahịa mmiri ara ehi na-enweghị abụba na abụba, CMC nwere ike dochie akụkụ nke abụba mmiri ara ehi ma melite udidi na nkwụsi ike nke ngwaahịa ahụ.
Ofe na ihe na-esi ísì ụtọ: N'ime ihe e ji esi nri salad, ihendori tomato na ihendori soy, CMC na-arụ ọrụ dị ka ihe na-eme ka ihe dị arọ ma na-eme ka ihe dị arọ dịkwuo mma iji melite otu ngwaahịa ahụ, zere mmebi, ma mee ka ngwaahịa ahụ kwụsie ike.
Aịs krịm na ihe ọṅụṅụ oyi: Ịtinye CMC na ịs krịm na ihe ọṅụṅụ oyi nwere ike ime ka nhazi nke ngwaahịa ahụ ka mma, mee ka ọ dịkwuo nkọ ma na-agbanwe agbanwe, na-egbochi ịmepụta kristal ice ma na-eme ka uto ya ka mma.
Achịcha na ihe e ji eme achịcha: N'ime ihe e ji eme achịcha dịka achịcha na achịcha, a na-eji CMC eme ihe dị ka ihe na-eme ka mgwakota agwa ahụ dịkwuo mma, mee ka achịcha ahụ dị nro, ma mee ka ọ dịruo ogologo oge.
3. Ngwa ndị ọzọ nke carboxymethyl cellulose na-eme ka ọ sie ike
Tinyere nri, a na-ejikarị carboxymethylcellulose eme ihe dị ka ihe na-eme ka ihe sie ike na ọgwụ, ihe ịchọ mma, kemịkalụ kwa ụbọchị na ụlọ ọrụ ndị ọzọ. Dịka ọmụmaatụ:
Ụlọ ọrụ ọgwụ: N'ọgwụ, a na-ejikarị CMC eme ka sirop, kapsụl, na mbadamba sie ike, ka ọgwụ ndị ahụ wee nwee mmetụta ịkpụzi na imebi ahụ nke ọma, ma nwee ike ime ka ọgwụ ndị ahụ kwụsie ike.
Ihe ịchọ mma na kemịkalụ kwa ụbọchị: N'ime kemịkalụ kwa ụbọchị dịka ezé ezé, shampoo, gel ịsa ahụ, wdg, CMC nwere ike ime ka ngwaahịa ahụ dịkwuo mma, melite ahụmịhe ojiji, ma mee ka mado ahụ dị otu ma kwụsie ike.
4. Nchekwa nke carboxymethyl cellulose
Nnyocha dị iche iche egosila na nchekwa nke carboxymethylcellulose dị na ya. Ebe ọ bụ na CMC sitere na cellulose eke ma anaghị agbari ma banye n'ime ahụ, ọ naghị emetụta ahụike mmadụ nke ọma. Ma Òtù Ahụike Ụwa (WHO) na Kọmitii Ọkachamara Jikọtara Ọnụ na Ihe Ndị Na-agbakwunye Nri (JECFA) na-akọwa ya dị ka ihe mgbakwunye nri dị mma. Na oke dose, CMC anaghị emepụta mmeghachi omume na-egbu egbu ma nwee ụfọdụ mmetụta mmanụ na laxative na eriri afọ. Agbanyeghị, oke oriri nwere ike ibute nsogbu afọ, yabụ a ga-agbaso ụkpụrụ dose edepụtara na mmepụta nri.
5. Uru na ọghọm nke carboxymethylcellulose
Carboxymethylcellulose nwere uru na oke ya dị ka ihe na-eme ka ihe dị arọ sie ike:
Uru: CMC nwere ezigbo mmiri na-agbaze, nkwụsi ike okpomọkụ na nkwụsi ike kemịkalụ, ọ na-eguzogide acid na alkali, ọ naghịkwa emebi ngwa ngwa. Nke a na-enye ohere ka ejiri ya mee ihe n'ọtụtụ ebe nhazi.
Ihe Ọjọọ: CMC nwere ike ịcha oke ma ọ bụrụ na e jiri ya mee ihe n'ọtụtụ dị elu, ọ dịghịkwa mma maka ngwaahịa niile. CMC ga-emebi n'ebe acidic dị, nke na-eme ka mmetụta ya ghara ịdị nkọ. A chọrọ ịkpachara anya mgbe a na-eji ya eme ihe n'ihe ọṅụṅụ ma ọ bụ nri ndị na-akpata acid.
Dịka ihe dị mkpa maka ihe na-eme ka ihe dị arọ sie ike, a na-ejikarị carboxymethylcellulose eme ihe n'ihe oriri, ọgwụ, ihe ịchọ mma na ihe ndị ọzọ n'ihi na ọ na-agbaze mmiri nke ọma, na-eme ka ọ sie ike ma kwụsie ike. Mmetụta ya na nchekwa ya dị elu na-eme ka ọ bụrụ ihe mgbakwunye a na-ejikarị eme ihe n'ụlọ ọrụ ọgbara ọhụrụ. Agbanyeghị, ojiji nke CMC kwesịkwara ịchịkwa sayensị dịka mkpa na ụkpụrụ dose si dị iji hụ na arụmọrụ ya na nchekwa nri ya ka mma.
