I-Carboxymethyl cellulose (CMC)iyi-anionic cellulose ether eyakhiwe ukuguqulwa kwamakhemikhali ku-cellulose. Isetshenziswa kakhulu ekudleni, emithini, kumakhemikhali ansuku zonke, e-petroleum, ekwenzeni iphepha nakwezinye izimboni ngenxa yokuqina kwayo okuhle, ukwakheka kwefilimu, ukuhlanganisa, ukumisa nokuthambisa izindawo. I-CMC inamabanga ahlukene. Ngokusho kokuhlanzeka, izinga lokushintshwa (i-DS), i-viscosity kanye nezimo ezisebenzayo, amamaki ajwayelekile angahlukaniswa ngokwezinga lezimboni, ibanga lokudla kanye nebanga lezemithi.
1. I-carboxymethyl cellulose yezinga lezimboni
I-Industrial grade CMC ingumkhiqizo oyisisekelo osetshenziswa kabanzi emikhakheni eminingi yezimboni. Isetshenziswa kakhulu emasimini kawoyela, ukwenza iphepha, izitsha zobumba, izindwangu, ukuphrinta nokudaya nezinye izimboni, ikakhulukazi ekwelashweni kodaka ekukhishweni kukawoyela kanye ne-ejenti yokuqinisa ekukhiqizeni iphepha.
I-Viscosity: Uhla lwe-viscosity lwebanga lezimboni lwe-CMC lubanzi, kusukela ku-viscosity ephansi kuya ku-viscosity ephezulu ukuhlangabezana nezidingo zezinhlelo zokusebenza ezahlukene. I-viscosity ephezulu ye-CMC ilungele ukusetshenziswa njengesihlanganisi, kuyilapho i-viscosity ephansi ifanele ukusetshenziswa njengesijingi nesiqinisayo.
I-Degree of substitution (DS): Izinga lokushintshwa kwe-CMC yezinga lezimboni jikelele liphansi, cishe ngo-0.5-1.2. Izinga eliphansi lokushintsha lingakhuphula isivinini i-CMC encibilika ngaso emanzini, liyivumele ukuthi yakhe i-colloid ngokushesha.
Izindawo zokufaka isicelo:
Ukumba uwoyela:I-CMCisetshenziswa njenge-thickener kanye ne-ejenti yokumisa odakeni lokumba ukuze kuthuthukiswe i-rheology yodaka futhi kuvimbele ukuwa kodonga lomthombo.
Imboni yokwenza amaphepha: I-CMC ingasetshenziswa njengesithuthukisi se-pulp ukuze kuthuthukiswe amandla aqinile nokumelana nokugoqa kwephepha.
Imboni ye-Ceramic: I-CMC isetshenziswa njenge-thickener ye-ceramic glaze, engathuthukisa ngempumelelo ukunamathela nokushelela kwe-glaze futhi ithuthukise umphumela wokwenza ifilimu.
Izinzuzo: I-CMC yezinga lezimboni inezindleko eziphansi futhi ifanele ukukhiqizwa kwezimboni ezinkulu.
2. I-carboxymethyl cellulose yezinga lokudla
I-CMC yezinga lokudla isetshenziswa kabanzi embonini yokudla, ikakhulukazi njenge-thickener, emulsifier, stabilizer, njll. ukuthuthukisa ukunambitheka, ukuthungwa kanye nempilo yeshelufu yokudla. Leli banga le-CMC linezidingo eziphakeme zokuhlanzeka, amazinga enhlanzeko nokuphepha.
I-Viscosity: I-viscosity ye-CMC yebanga lokudla imvamisa iphansi ukuya kwemaphakathi, ivamise ukulawulwa phakathi kuka-300-3000mPa·s. I-viscosity ethize izokhethwa ngokuya ngesimo sohlelo lokusebenza kanye nezidingo zomkhiqizo.
I-Degree of substitution (DS): Izinga lokushintshwa kwe-CMC yebanga lokudla ngokuvamile lilawulwa phakathi kuka-0.65-0.85, elinganikeza i-viscosity emaphakathi nokuncibilika okuhle.
Izindawo zokufaka isicelo:
Imikhiqizo yobisi: I-CMC isetshenziswa emikhiqizweni yobisi efana no-ayisikhilimu neyogathi ukwandisa i-viscosity nokunambitha komkhiqizo.
Iziphuzo: Eziphuzweni zejusi netiye, i-CMC ingasebenza njengesiqinisi sokumisa ukuvimbela i-pulp ukuthi ingahlali.
Ama-noodle: Kuma-noodle nama-noodle elayisi, i-CMC ingakhuphula ngempumelelo ukuqina nokunambitheka kwama-noodle, iwenze anwebeke kakhulu.
Ama-condiments: Kusoso namasaladi okugqokisa, i-CMC isebenza njenge-thickener ne-emulsifier ukuvimbela ukuhlukaniswa kwamanzi kawoyela kanye nokwelula impilo yeshalofu.
Izinzuzo: I-CMC yezinga lokudla ihlangabezana nezindinganiso zokuhlanzeka kokudla, ayinangozi emzimbeni womuntu, iyancibilika emanzini abandayo futhi ingakha ngokushesha ama-colloid, futhi iba nemiphumela emihle kakhulu yokujiya nokuzinza.
3. I-carboxymethyl cellulose yezinga lezemithi
I-Pharmaceutical-gradeI-CMCidinga ukuhlanzeka okuphezulu kanye namazinga okuphepha futhi isetshenziswa kakhulu ekwenziweni kwemithi kanye namadivayisi ezokwelapha. Leli banga le-CMC kufanele lihlangabezane namazinga e-pharmacopoeia futhi lilawule ikhwalithi eliqinile ukuze kuqinisekiswe ukuthi alinabuthi futhi alicunuli.
I-Viscosity: Uhla lwe-viscosity lwe-CMC yebanga lezemithi lucwengisiswe kakhulu, ngokuvamile phakathi kuka-400-1500mPa·s, ukuze kuqinisekiswe ukulawuleka kwalo nokuzinza kwezemithi nezicelo zezokwelapha.
I-Degree of substitution (DS): Izinga lokushintshwa kwebanga lezemithi ngokuvamile liphakathi kuka-0.7-1.2 ukuze kuhlinzekwe ukunyibilika nokuzinza okufanele.
Izindawo zokufaka isicelo:
Amalungiselelo ezidakamizwa: I-CMC isebenza njenge-binder kanye ne-disintegrant yamaphilisi, okungakhuphula ubulukhuni nokuzinza kwamaphilisi, futhi ingahlakazeka ngokushesha emzimbeni.
Amaconsi esweni: I-CMC isebenza njenge-thickener kanye ne-moisturizer yezidakamizwa ze-ophthalmic, ezingalingisa izici zezinyembezi, zisize ukugcoba amehlo, futhi zidambise izimpawu zamehlo omile.
Ukugqoka amanxeba: I-CMC ingenziwa ibe ifilimu esobala kanye nezingubo zokugqokisa ezifana nejeli zokunakekelwa kwenxeba, nokugcinwa kahle komswakama kanye nokuphefumula, okugqugquzela ukupholiswa kwesilonda.
Izinzuzo: I-CMC yebanga lezokwelapha ihlangabezana nezindinganiso ze-pharmacopoeia, inokuhambisana ne-biocompatibility ephezulu kanye nokuphepha, futhi ilungele ngomlomo, umjovo nezinye izindlela zokuphatha.
4. Amabanga akhethekile we-carboxymethyl cellulose
Ngaphezu kwamabanga amathathu angenhla, i-CMC ingenziwa ngokwezifiso ngokwezidingo ezithile zemikhakha ehlukene, njengebanga lezimonyo le-CMC, i-CMC yebanga lokuxubha amazinyo, njll. Amabanga akhethekile anjalo e-CMC ngokuvamile anezakhiwo eziyingqayizivele ukuhlangabezana nezidingo ezikhethekile zemboni.
I-CMC yebanga lezimonyo: isetshenziswa emikhiqizweni yokunakekelwa kwesikhumba, imaski yobuso, njll., eyakha ifilimu enhle nokugcina umswakama.
I-CMC yebanga lomuthi wokuxubha amazinyo: isetshenziswa njenge-thickener ne-adhesive ukunikeza umuthi wokuxubha uhlobo olungcono lokunamathisela kanye noketshezi.
I-Carboxymethyl celluloseinohlelo olubanzi lwezinhlelo zokusebenza kanye nezinketho ezahlukene zebanga. Ibanga ngalinye linezakhiwo ezithile zomzimba namakhemikhali ukuze kuhlangatshezwane nezidingo zezimboni ezahlukene.
