Carboxymethyl cellulose (CMC)bụ ether cellulose anionic nke emere site na mgbanwe kemịkalụ nke cellulose. A na-eji ya n'ọtụtụ ebe na nri, ọgwụ, kemịkalụ kwa ụbọchị, mmanụ ala, imepụta akwụkwọ na ụlọ ọrụ ndị ọzọ n'ihi na ọ na-eme ka ọ dị mma, na-emepụta fim, emulsifying, suspending and moisturizing properties. CMC nwere ọkwa dị iche iche. Dị ka ịdị ọcha, ogo nnọchi (DS), viscosity na ọdabara ndapụta, enwere ike kewaa akara ule na ọkwa ụlọ ọrụ, ọkwa nri na ọkwa ọgwụ.
1. Ụlọ ọrụ mmepụta ihe carboxymethyl cellulose
Ụlọ ọrụ mmepụta ihe CMC bụ ngwaahịa bụ isi a na-ejikarị eme ihe n'ọtụtụ ebe mmepụta ihe. A na-ejikarị ya na mpaghara mmanụ, imepụta akwụkwọ, ceramik, textiles, mbipụta na ịcha akwa na ụlọ ọrụ ndị ọzọ, karịsịa na ọgwụgwọ apịtị na mmịpụta mmanụ na onye na-agba ume na mmepụta akwụkwọ.
Viscosity: The viscosity nso nke ụlọ ọrụ ọkwa CMC dị obosara, sitere na viscosity dị ala ruo elu viscosity iji gboo mkpa nke ngwa dị iche iche. CMC viscosity dị elu kwesịrị ekwesị maka iji ya dị ka ihe nkedo, ebe obere viscosity kwesịrị ekwesị maka iji dị ka thickener na stabilizer.
Ọkwa nke nnọchi (DS): Ogo nke nnọchi nke ụlọ ọrụ mmepụta ihe-ọkwa CMC dị ala, gbasara 0.5-1.2. Ngbanwe dị ala nwere ike ịbawanye ọsọ nke CMC na-agbaze na mmiri, na-enye ya ohere ịmepụta colloid ngwa ngwa.
Mpaghara ngwa:
Ịgbapu mmanụ:CMCa na-eji ya eme ihe dị ka onye na-ekpo ọkụ na nkwụsịtụ na-egwupụta ụrọ iji mee ka rheology nke apịtị dịkwuo mma ma gbochie ọdịda nke mgbidi olulu mmiri.
Ụlọ ọrụ na-emepụta akwụkwọ: Enwere ike iji CMC mee ihe dị ka ihe na-ebuli elu iji kwalite ike nkwụsị na mpịachi nke akwụkwọ.
Ụlọ ọrụ seramiiki: A na-eji CMC eme ihe dị ka onye na-agba ume maka glaze seramiiki, nke nwere ike imeziwanye adhesion na ire ụtọ nke glaze ma welie mmetụta na-emepụta ihe nkiri.
Uru: Industrial-grade CMC nwere ọnụ ala dị ala ma dabara adaba maka mmepụta ụlọ ọrụ buru ibu.
2. Nri-ọkwa carboxymethyl cellulose
Food-ọkwa CMC ọtụtụ-eji na nri ụlọ ọrụ, tumadi dị ka a thickener, emulsifier, stabilizer, wdg iji melite uto, udidi na shelf ndụ nke nri. Ọkwa CMC a nwere nnukwu ihe achọrọ maka ịdị ọcha, ụkpụrụ ịdị ọcha na nchekwa.
Viscosity: Viscosity nke ọkwa nri CMC na-adịkarị ala ruo ọkara, a na-achịkwa ya n'etiti 300-3000mPa·s. A ga-ahọrọ viscosity a kapịrị ọnụ dabere na ọnọdụ ngwa yana mkpa ngwaahịa.
Degree nke nnọchi (DS): A na-achịkwa ogo nke nnọchi nke ọkwa nri CMC n'etiti 0.65-0.85, nke nwere ike inye viscosity na-agafeghị oke na ezigbo solubility.
Mpaghara ngwa:
Ngwaahịa mmiri ara ehi: A na-eji CMC na ngwaahịa mmiri ara ehi dị ka ice cream na yogọt iji mee ka viscosity na uto ngwaahịa ahụ dịkwuo elu.
Ihe ọṅụṅụ: N'ime ihe ọṅụṅụ na ihe ọṅụṅụ tii, CMC nwere ike rụọ ọrụ dị ka ihe nkwụsịtụ iji gbochie pulp site na idozi.
Noodles: Na noodles na osikapa, CMC nwere ike ịbawanye ike na uto nke noodles nke ọma, na-eme ka ọ dịkwuo mma.
Condiments: Na sauces na salad mgbakwasa, CMC na-eme dị ka thickener na emulsifier iji gbochie mmanụ-mmiri nkewa na ịgbatị ndụ shelf.
Uru: CMC-ọkwa nri na-ezute ụkpụrụ ịdị ọcha nke nri, adịghị emerụ ahụ mmadụ, na-agbaze na mmiri oyi ma nwee ike ịmepụta colloid ngwa ngwa, ma nwee mmetụta dị mma na-eme ka ahụ sie ike.
3. Ọgwụ-ọkwa carboxymethyl cellulose
Ọgwụ-ọkwaCMCchọrọ ịdị ọcha na ụkpụrụ nchekwa dị elu ma a na-ejikarị ya eme ihe n'ichepụta ọgwụ na ngwaọrụ ahụike. Nke a ọkwa nke CMC ga-emezurịrị ụkpụrụ pharmacopoeia ma na-achịkwa àgwà siri ike iji hụ na ọ dịghị egbu egbu na nke na-adịghị ewe iwe.
Viscosity: The viscosity nso nke ọgwụ-ọkwa CMC bụ ihe nụchara anụcha, n'ozuzu n'etiti 400-1500mPa·s, iji hụ na ya controllability na kwụsie ike na ọgwụ na ọgwụ ngwa.
Degree of nnọchi (DS): Ogo nke nnọchi nke akara ọgwụ na-abụkarị n'etiti 0.7-1.2 iji nye solubility na nkwụsi ike kwesịrị ekwesị.
Mpaghara ngwa:
Nkwadebe ọgwụ: CMC na-arụ ọrụ dị ka ihe nkedo na nkwụsịtụ maka mbadamba nkume, nke nwere ike ịbawanye ike na nkwụsi ike nke mbadamba nkume, ma nwee ike ịgbasa ngwa ngwa n'ime ahụ.
Anya na-adaba: CMC na-arụ ọrụ dị ka ihe na-agbapụta na mmiri mmiri maka ọgwụ ophthalmic, nke nwere ike iṅomi àgwà nke anya mmiri, nyere aka mmanu anya, ma wepụ ihe mgbaàmà anya nkụ.
Mgbakwasa ọnya: Enwere ike ịme CMC ka ọ bụrụ ihe nkiri transperent na gel-dị ka uwe maka nlekọta ọnya, na-ejigide mmiri dị mma na iku ume, na-akwalite ọgwụgwọ ọnya.
Uru: Ọkwa ahụike CMC na-ezute ụkpụrụ pharmacopoeia, nwere nnukwu bioocompatibility na nchekwa, ma dabara maka ọnụ, ịgba ọgwụ mgbochi na ụzọ nchịkwa ndị ọzọ.
4. Pụrụ iche akara ule nke carboxymethyl cellulose
Na mgbakwunye na akara ule atọ ndị dị n'elu, CMC nwekwara ike ịhazi dịka mkpa dị iche iche nke ubi dị iche iche si dị, dị ka ọkwa CMC ịchọ mma, ọkwa eze eze CMC, wdg. Ụdị akara ngosi pụrụ iche nke CMC na-enwekarị ihe pụrụ iche iji gboo ihe pụrụ iche chọrọ nke ụlọ ọrụ ahụ.
