Gukora carboxymethylcellulose (CMC) bikubiyemo intambwe nyinshi hamwe nubushakashatsi bwimiti.CMC ni polymer yamazi ashonga ikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima.Ikoreshwa cyane mu nganda zitandukanye nk'ibiribwa, imiti, imiti yo kwisiga, n'imyenda bitewe n'ubunini bwayo, itekanye, kandi ihuza.Dore inzira irambuye yuburyo bwo gukora carboxymethylcellulose:
Intangiriro kuri Carboxymethylcellulose (CMC):
Carboxymethylcellulose (CMC) ni inkomoko ya selile, isanzwe ibaho polysaccharide iboneka mu rukuta rw'utugingo ngengabuzima.Umusaruro wa CMC urimo guhindura selile ukoresheje reaction ya chimique kugirango winjize amatsinda ya carboxymethyl kumugongo wa selile.Ihinduka ritanga amazi meza hamwe nibindi bintu byifuzwa kuri polymer.
Ibikoresho bibisi:
Cellulose: Ibikoresho byibanze byumusaruro wa CMC ni selile.Cellulose irashobora gukomoka ahantu hatandukanye nkibiti byimbuto, ibiti by'ipamba, cyangwa ibisigazwa byubuhinzi.
Sodium Hydroxide (NaOH): Bizwi kandi nka soda ya caustic, hydroxide ya sodium ikoreshwa mugice cyambere cyumusaruro wa CMC kugirango ivure selile.
Acide ya Chloroacetic (ClCH2COOH): Acide Chloroacetic niyo reagent nyamukuru ikoreshwa mugutangiza amatsinda ya carboxymethyl kumugongo wa selile.
Etherification Catalyst: Catalizator nka sodium hydroxide cyangwa sodium karubone ikoreshwa kugirango byorohereze etherification reaction hagati ya selile na acide chloroacetic.
Umuti: Umuti nka isopropanol cyangwa Ethanol urashobora gukoreshwa mugushonga reaction hamwe nubufasha mugikorwa cya reaction.
Uburyo bwo kubyaza umusaruro:
Umusaruro wa carboxymethylcellulose urimo intambwe zingenzi:
1. Kuvura Alkali ya Cellulose:
Cellulose ivurwa na alkali ikomeye, mubisanzwe hydroxide ya sodium (NaOH), kugirango yongere imbaraga zayo ihindura amwe mumatsinda ya hydroxyl na selile alkali.Ubu buvuzi busanzwe bukorerwa mu cyombo cya reaction ku bushyuhe bwo hejuru.Alkali selulose yakozwe noneho irakaraba kandi ikabogama kugirango ikureho alkali irenze.
2. Kwiyongera:
Nyuma yo kuvura alkali, selile ikorwa na aside ya chloroacetike (ClCH2COOH) imbere ya catalizike ya etherification.Iyi reaction itangiza amatsinda ya carboxymethyl kumugongo wa selile, bigatuma habaho carboxymethylcellulose.Imyitwarire ya etherification mubisanzwe ibaho mugihe cyubushyuhe bwubushyuhe, umuvuduko, na pH kugirango ugere kurwego rwifuzwa rwo gusimburwa (DS) nuburemere bwa molekile ya CMC.
3. Gukaraba no kwezwa:
Nyuma ya reaction ya etherification, ibicuruzwa bya CMC bitameshe byogejwe neza kugirango bikureho reagent zidakozwe, ibicuruzwa, nibihumanya.Gukaraba mubisanzwe bikorwa hakoreshejwe amazi cyangwa ibishishwa kama bikurikirwa no kuyungurura cyangwa centrifugation.Intambwe yo kweza irashobora kandi kubamo kuvura hamwe na acide cyangwa shingiro kugirango uhindure pH no gukuraho catisale zisigaye.
4. Kuma:
CMC isukuye noneho yumishwa kugirango ikureho ubuhehere no kubona ibicuruzwa byanyuma mubifu cyangwa muburyo bwa granular.Kuma mubisanzwe bikorwa hakoreshejwe uburyo nko kumisha spray, gukama vacuum, cyangwa guhumeka ikirere mugihe cyagenwe kugirango wirinde kwangirika cyangwa guhuriza hamwe kwa polymer.
Kugenzura ubuziranenge:
Ingamba zo kugenzura ubuziranenge ningirakamaro muri gahunda yumusaruro wa CMC kugirango hamenyekane neza, ubuziranenge, nibintu byifuzwa byibicuruzwa byanyuma.Ibipimo byingenzi byingenzi birimo:
Impamyabumenyi yo gusimbuza (DS): Impuzandengo yimibare ya carboxymethyl kumatsinda ya glucose murwego rwa selile.
Gukwirakwiza uburemere bwa molekuline: Kugenwa nubuhanga nko gupima viscosity cyangwa gel permeation chromatografiya (GPC).
Isuku: Isuzumwa nuburyo bwisesengura nka infragre spekitroscopi (IR) cyangwa chromatografiya ikora cyane (HPLC) kugirango imenye umwanda.
Viscosity: Umutungo wingenzi kuri porogaramu nyinshi, zapimwe ukoresheje viscometer kugirango urebe neza kandi neza.
Porogaramu ya Carboxymethylcellulose:
Carboxymethylcellulose isanga ikoreshwa cyane mu nganda zitandukanye, harimo:
Inganda zikora ibiryo: Nkibyimbye, stabilisateur, na emulisiferi mubicuruzwa nka sosi, imyambarire, ice cream, nibicuruzwa bitetse.
Imiti ya farumasi: Mubikorwa bya farumasi nkibihuza, bidahwitse, hamwe na viscosity ihindura ibinini, guhagarikwa, hamwe nibisobanuro byingenzi.
Amavuta yo kwisiga: Mubicuruzwa byita kumuntu nka cream, amavuta yo kwisiga, na shampo nkibikoresho byibyimbye hamwe na rheologiya.
Imyenda: Mu icapiro ryimyenda, ingano, hamwe no kurangiza inzira kugirango utezimbere imyenda nimikorere.
Ibitekerezo by’ibidukikije n’umutekano:
Umusaruro wa CMC urimo gukoresha imiti nuburyo bukoresha ingufu nyinshi, zishobora kugira ingaruka ku bidukikije nko kubyara amazi mabi no gukoresha ingufu.Imbaraga zo kugabanya ingaruka z’ibidukikije no kwemeza ko imiti ikoreshwa neza ni ibintu byingenzi mu nganda za CMC.Gushyira mubikorwa uburyo bwiza bwo gutunganya imyanda, gukoresha ingufu, hamwe nubuzima bwakazi n’umutekano birashobora gufasha kugabanya izo mpungenge.
Umusaruro wa carboxymethylcellulose urimo intambwe nyinshi zitangirana no gukuramo selile kugeza kuvura alkali, etherification, kweza, no gukama.Ingamba zo kugenzura ubuziranenge ningirakamaro kugirango habeho guhuza no kweza ibicuruzwa byanyuma, usanga bikoreshwa mu nganda zitandukanye.Ibidukikije n’umutekano ni ingingo zingenzi z’umusaruro wa CMC, ushimangira ko hakenewe imikorere irambye kandi ishinzwe.
