Isingeniso seCarboxymethyl Cellulose (CMC)
I-Carboxymethyl cellulose, evame ukufushaniswa njenge-CMC, iphuma ezintweni ezihlukahlukene ze-cellulose, i-polymer eyenzeka ngokwemvelo etholakala ezindongeni zamaseli ezitshalo.Itholakala ngokuguqulwa kwamakhemikhali e-cellulose, ngokuyinhloko ngokusungulwa kwamaqembu e-carboxymethyl (-CH2-COOH) kumgogodla we-cellulose.
Isakhiwo Nezakhiwo
I-CMC igcina ukwakheka okuyisisekelo kwe-cellulose, okuwuchungechunge lomugqa wama-molecule eglucose axhunywe ngamabhondi e-β(1→4) e-glycosidic.Kodwa-ke, ukwethulwa kwamaqembu e-carboxymethyl kunikeza izici ezimbalwa ezibalulekile ku-CMC:
Ukunyibilika Kwamanzi: Ngokungafani ne-cellulose yomdabu, engancibiliki emanzini, i-CMC incibilika kakhulu emanzini ashisayo nabandayo ngenxa yemvelo ye-hydrophilic yamaqembu e-carboxymethyl.
I-ejenti yokujiya: I-CMC iyi-ejenti yokuqina esebenzayo, eyenza izixazululo ze-viscous ezindaweni eziphansi.Le ndawo iyenza ibaluleke ezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa ukudla, imithi, nemikhiqizo yokunakekelwa komuntu siqu.
Ikhono Lokwenza Ifilimu: I-CMC ingakha amafilimu lapho efakwe exazululweni, ikwenze abe usizo ezinhlelweni lapho kudingeka khona ifilimu elincanyana, eliguquguqukayo, njengakuma-coatings nezinamatheliso.
Ukuzinza Nokuvumelana: I-CMC izinzile phezu kwebanga elibanzi le-pH nezimo zokushisa, okuyenza ihambisane nezinye izithako ezihlukahlukene futhi ifanele ukusetshenziswa okuhlukahlukene.
Izinhlelo zokusebenza
Izakhiwo eziguquguqukayo ze-CMC zithola isicelo kuzo zonke izimboni ezimbalwa:
Imboni Yokudla: I-CMC isetshenziswa kabanzi njenge-thickener, stabilizer, kanye ne-emulsifier emikhiqizweni yokudla efana namasoso, okokugqoka, u-ayisikhilimu, nezinto zokubhaka.Ithuthukisa ukuthungwa, ukuzwa komlomo, nokuzinza kweshalofu.
Ezemithi: Ekwenziweni kwemithi, i-CMC isebenza njenge-binder, disintegrant, kanye ne-ejenti ekhishwayo elawulwayo kumaphilisi namaphilisi.Ikhono layo lokwenza ama-gel azinzile liphinde lenze libe usizo ekwakhiweni kwezihloko ezifana namakhilimu nama-lotions.
Imikhiqizo Yokunakekelwa Komuntu Siqu: I-CMC iyisithako esivamile emikhiqizweni yokunakekelwa komuntu siqu efana nomuthi wokuxubha amazinyo, ama-shampoos, nama-creams, lapho isebenza khona njenge-thickener, stabilizer, kanye nokugcina umswakama.
Imboni Yamaphepha: Ekwenziweni kwamaphepha, i-CMC isetshenziswa njenge-ejenti yokulinganisa indawo ukuze kuthuthukiswe amandla ephepha, ukushelela, nokwamukelwa kweyinki.Isebenza futhi njengosizo lokugcina, isiza ukubopha izinhlayiya ezinhle nezigcwalisi ephepheni.
Izindwangu: I-CMC isetshenziswa ezinqubweni zokuphrinta izindwangu kanye nokudaya njenge-thickener ne-rheology modifier yokuphrinta ama-paste namabhati odayi.
Ukumba Kawoyela: Embonini yokumba uwoyela, i-CMC yengezwa kuketshezi lokumba ukuze kuhlinzekwe ukulawula i-viscosity, ukunciphisa ukulahlekelwa uketshezi, kanye nokugcotshwa kwezingcezu zokubhoboza.
Ukusetshenziswa okwandile kwe-carboxymethyl cellulose kubangelwa inhlanganisela yayo eyingqayizivele yezakhiwo, eyenza ukusetshenziswa kwayo emikhakheni eyahlukene.Ukuwohloka kwayo kwemvelo kanye nokungabi nobuthi kuphinde kube nomthelela ekuthandeni kwayo njengendlela esimeme futhi enobungani bemvelo ehlukile kuma-polymer okwenziwa ezinhlelweni eziningi.
I-carboxymethyl cellulose ngempela iyi-ether ye-cellulose enezinhlobonhlobo zezinhlelo zokusebenza ngenxa yokuncibilika kwayo emanzini, izakhiwo ezishubile, ukuzinza, nokuhambisana nezinye izinto.Ukubaluleka kwayo kuhlanganisa zonke izimboni, okuyenza ibe yingxenye ebalulekile emikhiqizweni nasezinqubweni eziningi.
