Carboxymethyl selulose (CMC) ni polymer yamazi yamazi akomoka kuri selile, akaba ari polymer kama nyinshi kwisi. CMC ikorwa no guhindura imiti ya selile, mubisanzwe biva mubiti cyangwa kumpamba. Ikoreshwa cyane muburyo butandukanye bwa porogaramu bitewe nimiterere yihariye, harimo nubushobozi bwayo bwo gukora ibisubizo bya viscous na geles, ubushobozi bwo guhuza amazi, hamwe na biodegradabilite.
Imiterere ya Shimi n'umusaruro
Imiterere yimiti ya CMC igizwe numugongo wa selile hamwe na carboxymethyl matsinda (-CH2-COOH) ifatanye na amwe mumatsinda ya hydroxyl (-OH) kuri monomers glucose. Ubu buryo bwo gusimbuza burimo kuvura selile hamwe na aside ya chloroacetike mu buryo bwa alkaline, biganisha kuri sodium carboxymethyl selulose. Urwego rwo gusimbuza (DS) bivuga impuzandengo ya hydroxyl ya groupe ya glucose yasimbujwe nitsinda rya carboxymethyl, hamwe na DS ya 0.4 kugeza 1.4 isanzwe mubisabwa byinshi.
Ibikorwa byo kubyaza umusaruro CMC birimo intambwe nyinshi:
Alkalisation: Cellulose ivurwa hamwe na base ikomeye, mubisanzwe hydroxide ya sodium, kugirango ikore alkali selile.
Etherification: selile ya alkali noneho ikorwa na aside ya chloroacetic, bikavamo gusimbuza amatsinda ya hydroxyl nitsinda rya carboxymethyl.
Isuku: CMC itagira isuku irakaraba kandi igasukurwa kugirango ikureho ibicuruzwa na reagent zirenze.
Kuma no gusya: CMC yatunganijwe yumishijwe kandi irasya kugirango ubone ingano yifuzwa.
Ibyiza
CMC izwiho imiterere idasanzwe, ituma igira akamaro mu nganda zitandukanye:
Amazi meza: CMC ihita ishonga mumazi, ikora ibisubizo bisobanutse neza.
Viscosity Modulation: Ubukonje bwibisubizo bya CMC burashobora guhinduka muguhindura intumbero hamwe nuburemere bwa molekile, bikagira akamaro mubyimbye no guhagarara neza.
Imiterere ya firime: Irashobora gukora firime zikomeye, zoroshye iyo zumye ziva mubisubizo.
Ibiranga ibintu bifatika: CMC yerekana ibintu byiza bifata neza, bifite akamaro mubisabwa nka adhesives na coatings.
Biodegradability: Kuba ikomoka kuri selile isanzwe, CMC irashobora kwangirika, bigatuma itangiza ibidukikije.
Inganda zikora ibiribwa
CMC ikoreshwa cyane nk'inyongeramusaruro (E466) kubera ubushobozi bwayo bwo guhindura ububobere no guhagarika emulisiyo mubicuruzwa bitandukanye byibiribwa. Ikora nkibibyimbye, stabilisateur, na emulisiferi mubicuruzwa nka ice cream, ibikomoka ku mata, ibikoni, hamwe na salade. Kurugero, muri ice cream, CMC ifasha gukumira imiterere ya kirisita, bikavamo uburyo bworoshye.
Imiti n’imiti yo kwisiga
Mu nganda zikoreshwa mu bya farumasi, CMC ikoreshwa nka binder mu bisate, bidahwitse, kandi byongera ububobere mu guhagarika no gusohora. Ikora kandi nka stabilisateur mu mavuta yo kwisiga, amavuta, na geles mu nganda zo kwisiga. Kamere yacyo idafite uburozi kandi idatera uburakari ituma ikwiriye gukoreshwa muri ibyo bicuruzwa.
Impapuro n'imyenda
CMC ikoreshwa munganda zimpapuro nkumukozi ufite ubunini bwo kunoza imbaraga no gucapura impapuro. Mu myenda, ikoreshwa nkibikoresho byiyongera muburyo bwo gusiga irangi kandi nkibigize ibikoresho byo gucapa imyenda, byongera uburinganire nubwiza bwicapiro.
Ibikoresho byoza ibikoresho hamwe nogusukura
Mu bikoresho byo kumesa, CMC ikora nk'umukozi uhagarika ubutaka, ikabuza umwanda gusubira ku mwenda mugihe cyo gukaraba. Itezimbere kandi imikorere yimyunyu ngugu yongerera ubwiza no gutuza.
Gucukura peteroli no gucukura amabuye y'agaciro
CMC ikoreshwa mumazi yo gucukura amavuta kugirango igenzure ubukonje kandi nkumuhinduzi wa rheologiya kugirango ibungabunge umutekano wibyondo byacukuwe, birinda gusenyuka kwimyobo no koroshya gukuraho ibiti. Mu bucukuzi bw'amabuye y'agaciro, bukoreshwa nk'umukozi wa flotation na flocculant.
Ubwubatsi nububumbyi
Mu nganda zubaka, CMC ikoreshwa mugukora sima na minisiteri kugirango amazi agabanuke kandi akore neza. Mububumbyi, bukora nka binder na plasitike muri paste ceramic, kunoza imiterere yabyo no kumisha.
Ibidukikije n'umutekano
Ubusanzwe CMC ifatwa nkumutekano (GRAS) ninzego zibishinzwe nka FDA. Ntabwo ari uburozi, ntabwo allerge, na biodegradable, bigatuma ibidukikije byangiza ibidukikije. Nyamara, uburyo bwo kubyaza umusaruro burimo imiti igomba gukoreshwa neza kugirango hirindwe ibidukikije. Kujugunya neza no gutunganya ibicuruzwa ni ngombwa kugirango hagabanuke ingaruka z’ibidukikije.
Udushya hamwe nicyerekezo kizaza
Iterambere rya vuba murwego rwa CMC ririmo iterambere rya CMC ryahinduwe hamwe nibintu byongerewe imbaraga kubikorwa byihariye. Kurugero, CMC ifite uburemere bwa molekuline hamwe nintera yo gusimburwa irashobora gutanga imikorere inoze muri sisitemu yo gutanga ibiyobyabwenge cyangwa nkibikoresho bipakira bio. Byongeye kandi, ubushakashatsi burimo gukorwa burimo gushakisha imikoreshereze ya CMC mubice bishya nka injeniyeri ya tissue na bioprinting, aho ubushobozi bwa biocompatibilité hamwe nubushobozi bwo gukora gel bishobora kuba ingirakamaro cyane.
Carboxymethyl selulose ni ibintu byinshi kandi bifite agaciro hamwe nurwego runini rwa porogaramu mu nganda zitandukanye. Imiterere yihariye, harimo gushiramo amazi, guhindagurika kwijimye, hamwe na biodegradabilite, bituma iba ikintu cyingenzi mubicuruzwa byinshi. Hamwe niterambere ridahwema kubyaza umusaruro no kuyihindura, CMC yiteguye kugira uruhare runini mubice gakondo ndetse no kuvuka, bigira uruhare mubikorwa byiterambere ndetse niterambere rirambye.
