Carboxymethylcellulose (CMC), yomwe imadziwikanso kuti cellulose chingamu, ndi polima wosunthika wokhala ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana.Pagululi, lochokera ku cellulose, limawonetsa zinthu zapadera zomwe zimapangitsa kuti zikhale zofunikira kwambiri m'magawo monga chakudya, mankhwala, zodzoladzola, nsalu, ndi zina zambiri.
Kapangidwe ndi Katundu
Ma cellulose, ma polima ochuluka kwambiri padziko lapansi, amagwira ntchito ngati chigawo choyambirira cha makoma a zomera.Ndi mzere wa polysaccharide wopangidwa ndi mayunitsi obwerezabwereza olumikizidwa ndi β(1→4) glycosidic bond.Carboxymethylcellulose ndi chochokera ku cellulose yomwe imapezeka kudzera mukusintha kwamankhwala.
Kusintha kwakukulu kumaphatikizapo kuyambitsa magulu a carboxymethyl (-CH2-COOH) pamagulu a hydroxyl a msana wa cellulose.Izi, zomwe zimachitika kudzera mu etherification kapena esterification reaction, zimapereka kusungunuka kwamadzi ndi zinthu zina zofunika ku molekyulu ya cellulose.
Digiri ya m'malo (DS) imatanthawuza kuchuluka kwa magulu a carboxymethyl omwe amalumikizidwa ku gawo lililonse la anhydroglucose mu unyolo wa cellulose.Zimakhudza kwambiri kusungunuka, kukhuthala, ndi mawonekedwe ena a CMC.Makhalidwe apamwamba a DS amatsogolera kusungunuka kwakukulu ndi mayankho okhuthala.
Carboxymethylcellulose nthawi zambiri imapezeka m'makalasi osiyanasiyana, iliyonse yopangidwa kuti ikwaniritse zofunikira zinazake.Maphunzirowa amasiyana mu magawo monga mamasukidwe akayendedwe, digiri ya kusintha, kukula kwa tinthu, ndi kuyera.
Chimodzi mwazinthu zodziwika bwino za CMC ndikutha kwake kupanga mayankho a viscous m'madzi.Ngakhale pazigawo zotsika, zimatha kupangitsa kuti ziwonjezeke chifukwa cholumikizidwa ndi ma polima komanso kulumikizana ndi mamolekyu amadzi.Izi zimapangitsa kuti ikhale yabwino kwambiri yolimbikitsira pazinthu zambiri.
Kuphatikiza apo, carboxymethylcellulose imawonetsa zinthu zabwino kwambiri zopanga mafilimu, zomwe zimapangitsa kuti zikhale zothandiza popanga zokutira ndi makanema okhala ndi milingo yosiyana ya permeability komanso mphamvu zamakina.Makanemawa amapeza ntchito m'mafakitale kuyambira pakupanga zakudya mpaka kupanga mankhwala.
Mapulogalamu
Kusinthasintha kwa carboxymethylcellulose kumabwera chifukwa cha kuphatikiza kwake kwapadera, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mosiyanasiyana.Zina mwazofunikira za CMC ndizo:
Makampani a Chakudya: M'makampani azakudya, carboxymethylcellulose amagwira ntchito ngati stabilizer, thickener, ndi emulsifier muzinthu zambiri.Amagwiritsidwa ntchito kwambiri muzamkaka, sosi, mavalidwe, zinthu zowotcha, ndi zakumwa kuti azitha kukhazikika, kumveka mkamwa, komanso kukhazikika kwa shelufu.Kuphatikiza apo, CMC imagwiritsidwa ntchito popanga ma gluteni kuti atsanzire kapangidwe ka gilateni muzophika.
Pharmaceuticals: CMC imapeza kugwiritsidwa ntchito kwambiri pakupanga mankhwala chifukwa cha kuthekera kwake kukulitsa kukhuthala komanso kusasinthika kwa kuyimitsidwa, ma emulsion, ndi mafuta odzola.Imagwira ntchito ngati chomangira pamipangidwe yamapiritsi, chosinthira mamasukidwe amkamwa muzamadzimadzi amkamwa, komanso chokhazikika muzopakapaka topical creams ndi lotions.Kuphatikiza apo, carboxymethylcellulose imagwiritsidwa ntchito ngati chophimbira pamapiritsi, kupangitsa kuti mankhwala azisamalidwe bwino komanso kuti athe kumeza.
Zodzoladzola ndi Kusamalira Munthu: Muzodzoladzola ndi zinthu zosamalira anthu, CMC imagwira ntchito ngati yokhuthala, yokhazikika, komanso yonyowa.Amaphatikizidwa muzopanga monga zonona, mafuta odzola, ma shampoos, ndi mankhwala otsukira mano kuti awonjezere mawonekedwe, kukulitsa kukhuthala, ndikupereka kusasinthasintha, kofanana.
Zovala: M'makampani opanga nsalu, carboxymethylcellulose amagwiritsidwa ntchito ngati chopangira zitsulo kuti azitha kuluka ndikupangitsa kuti nsalu zikhale zowuma.Amagwiritsidwanso ntchito ngati thickener mu nsalu zosindikizira phalas kuonetsetsa kufanana ndi chakuthwa kwa mapangidwe osindikizidwa.
Mafuta ndi Gasi: CMC imagwiritsidwa ntchito m'makampani amafuta ndi gasi ngati makina opangira ma viscosifier pobowola matope.Imathandiza kuwongolera kutayika kwamadzimadzi, kukonza kuyeretsa mabowo, komanso kukhazikika pobowola.Kuphatikiza apo, carboxymethylcellulose imapeza ntchito m'madzi a hydraulic fracturing kuti ayimitse othandizira ndikunyamula zowonjezera kuti apange.
Mapepala ndi Kupaka: Pamakampani opanga mapepala, CMC imagwira ntchito ngati chotchingira kuti ipititse patsogolo mawonekedwe a pepala, kukulitsa kusindikiza, ndikuwonjezera kukana chinyezi.Amagwiritsidwanso ntchito ngati sing agent kuti apange mphamvu zamapepala ndikuchepetsa kuyamwa kwamadzi.Kuphatikiza apo, carboxymethylcellulose imagwiritsidwa ntchito pakuyika zida kuti zithandizire kukana chinyezi ndikuwongolera kumamatira mu laminates.
Zomangamanga: Carboxymethylcellulose amagwiritsidwa ntchito muzomangamanga monga matope, ma grouts, ndi pulasitala kuti azitha kugwira bwino ntchito, kumamatira, komanso kusunga madzi.Zimagwira ntchito ngati zowonjezera komanso zosintha za rheology, kuwonetsetsa kugwiritsa ntchito moyenera komanso kuchita bwino kwa zinthuzi.
Ntchito Zina: Kupitilira mafakitale omwe tawatchulawa, CMC imapeza ntchito zosiyanasiyana monga zotsukira, zomatira, zoumba, ndi kuthira madzi.Kusinthasintha kwake komanso kugwirizana ndi zinthu zina kumapangitsa kukhala chowonjezera chofunikira pamapangidwe ndi njira zambiri.
Kufunika ndi Ubwino
Kugwiritsiridwa ntchito kofala kwa carboxymethylcellulose kungabwere chifukwa cha zabwino ndi zabwino zake:
Kusinthasintha: Kutha kwa CMC kugwira ntchito zingapo, kuphatikiza kukhuthala, kukhazikika, kumanga, ndi kupanga mafilimu, kumapangitsa kuti ikhale yosunthika m'mafakitale osiyanasiyana.
Chitetezo: Carboxymethylcellulose nthawi zambiri imadziwika kuti ndi yotetezeka (GRAS) kuti igwiritsidwe ntchito ndi olamulira monga US Food and Drug Administration (FDA).Imayika chiwopsezo chochepa ku thanzi la anthu ndipo ili ndi mbiri yakale yogwiritsidwa ntchito motetezeka muzakudya, zamankhwala, ndi zinthu zosamalira anthu.
Eco-Friendly: Monga chochokera ku cellulose, CMC imachokera ku zomera zongowonjezedwanso, ndikupangitsa kuti ikhale yosasunthika.Ndi biodegradable ndipo sathandizira kuwononga chilengedwe.
Mtengo Wogwira Ntchito: Carboxymethylcellulose imapereka njira yotsika mtengo yolimbikitsira zinthu zamitundu yosiyanasiyana ndi mapangidwe.Mtengo wake wotsika poyerekeza ndi zina zowonjezera zimapangitsa kukhala chisankho chokondedwa kwa opanga ambiri.
Magwiridwe: Makhalidwe apadera a CMC, monga kuthekera kwake kupanga kuyimitsidwa kokhazikika, ma gels wandiweyani, ndi makanema amphamvu, amathandizira pakuchita bwino komanso mtundu wazinthu zomaliza.
Kutsata Malamulo: Carboxymethylcellulose imagwirizana ndi malamulo ndi zofunikira m'mafakitale osiyanasiyana, kuwonetsetsa chitetezo chazinthu ndi khalidwe.
carboxymethylcellulose (CMC) imagwira ntchito yofunika kwambiri m'mafakitale ambiri ngati polima wosunthika wokhala ndi ntchito zosiyanasiyana.Kuyambira pazakudya ndi mankhwala mpaka zovala ndi zomangamanga, CMC imapereka zinthu zapadera zomwe zimakulitsa magwiridwe antchito, mtundu, ndi magwiridwe antchito amitundu yosiyanasiyana yazinthu ndi mapangidwe.Chitetezo chake, kukhazikika, komanso kutsika mtengo kumathandiziranso kufunikira kwake munjira zamakono zopangira.Pamene kafukufuku ndi zatsopano zikupitilira kukulitsa kumvetsetsa kwa zotumphukira za cellulose, kugwiritsa ntchito ndi kufunikira kwa carboxymethylcellulose akuyembekezeka kukula kwambiri m'zaka zikubwerazi.
