I-Carboxymethylcellulose (CMC), Eyaziwa ngokuthi yi-cellulose gum, iphuma ezintweni eziningi futhi esetshenziswa kabanzi ephuma ku-cellulose esebenza kaningi kuzo zonke izimboni ezihlukahlukene.Le polymer encibilika emanzini isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.Kulokhu kuhlola okuphelele, sihlolisisa ukwakheka kwe-carboxymethylcellulose, izakhiwo zayo, izinqubo zokukhiqiza, kanye nokusetshenziswa okuhlukahlukene kuzo zonke izimboni zokudla neziphuzo, ezemithi, izimonyo, izindwangu, nezinye izimboni.
Isakhiwo seCarboxymethylcellulose (CMC):
I-Carboxymethylcellulose ikhiqizwa i-cellulose eshintsha amakhemikhali ngokusebenzisa izinqubo ze-etherification ne-carboxymethylation.Lezi zinguquko zibandakanya ukwethula amaqembu e-carboxymethyl kumgogodla we-cellulose.I-degree of substitution (DS), emele inani elimaphakathi lamaqembu e-carboxymethyl ngeyunithi ngayinye ye-anhydroglucose ku-cellulose, ingalawulwa phakathi nenqubo yokukhiqiza.Lokhu kuguqulwa kunikeza izakhiwo ezithile ku-CMC, kuyenze inyibilike emanzini futhi ifanele uhla olubanzi lwezinhlelo zokusebenza.
Izici ze-Carboxymethylcellulose:
1. Ukunyibilika kwamanzi:
Esinye sezici ezibalulekile ze-CMC ukuncibilika kwayo emanzini.Incibilika emanzini ukwenza isixazululo esicacile, esibonakalayo.Lesi sakhiwo sibaluleke kakhulu ezimbonini lapho ukwakheka okusekelwe emanzini kukhethwa khona.
2. Ukulawulwa Kwe-Viscosity:
I-CMC yaziwa ngekhono layo lokulawula i-viscosity yezixazululo ezinamanzi.Lokhu kuyenza ibe i-ejenti ejiyayo ebalulekile ezinhlelweni ezehlukene, kusukela emikhiqizweni yokudla kuye ekwenziweni kwemithi.
3. Ukuzinzisa kanye Nokumiswa:
I-CMC isebenza njengesiqinisi futhi ingasetshenziswa ukumisa izinhlayiya eziqinile ekwakhekeni koketshezi.Lokhu kubalulekile ezimbonini ezifana nezokudla nemithi, lapho ukusabalalisa izithako kubalulekile.
4. Izici Zokwenza Amafilimu:
I-CMC ikhombisa izakhiwo zokwenza ifilimu, iyenze ibe wusizo ezinhlelweni zokusebenza lapho ukwakheka kwefilimu elincanyana, eliguqukayo lifiseleka.Lesi sakhiwo sisetshenziswa ezimbonini ezifana nezindwangu, lapho i-CMC isetshenziswa khona ekulinganisweni nasekuqedeni izinqubo.
5. I-Biodegradability:
I-CMC ithathwa njengenobungani nemvelo njengoba isuselwa ezinsizeni ezivuselelekayo futhi ibola.Lokhu kuhambisana nokugcizelelwa okukhulayo kwezinto ezisimeme kanye ne-eco-friendly ezimbonini ezihlukahlukene.
Inqubo Yokukhiqiza I-Carboxymethylcellulose:
Ukukhiqizwa kwe-CMC kuhilela izinyathelo ezimbalwa, kuqala ngokukhethwa komthombo we-cellulose.I-Wood pulp iyinto evamile yokuqala, nakuba ukotini neminye imithombo esekelwe ezitshalweni ingase isetshenziswe.I-cellulose ingaphansi kokusabela kwe-alkali-catalyzed nge-sodium monochloroacetate, okuholela ku-carboxymethylation.Izinga lokushintsha lilawulwa ukuze kuzuzwe izakhiwo ezifiselekayo zezinhlelo zokusebenza ezithile.Ukusabela kulandelwa ukungathathi hlangothi kanye nezinqubo zokuhlanza ukuze kutholwe umkhiqizo wokugcina we-CMC.
Ukusetshenziswa kwe-Carboxymethylcellulose:
1. Imboni Yokudla Neziphuzo:
I-CMC isetshenziswa kabanzi embonini yokudla njenge-thickener, stabilizer, kanye ne-texturizer.Itholakala emikhiqizweni efana no-ayisikhilimu, amasoso, okokugqoka, nezinto ezibhakwayo.Eziphuzweni, i-CMC isetshenziselwa ukuzinzisa nokumisa izinhlayiya ekwakhiweni.
2. Ezemithi:
Ekwenziweni kwemithi, i-CMC isebenza njengesibopho ekukhiqizeni amaphilisi, ihlinzeka ngokuhlangana kwezithako eziyimpuphu.Ibuye isetshenziswe njengesilungisi se-viscosity emithini ewuketshezi futhi njenge-ejenti yokumisa ukumiswa ngomlomo.
3. Izimonyo Nemikhiqizo Yokunakekela Umuntu:
I-CMC ikhona ezintweni ezehlukene zezimonyo nezomuntu siqu, okuhlanganisa okhilimu, izinto zokugcoba, ama-shampoos, kanye nomuthi wokuxubha.Izakhiwo zayo ezijiyayo neziqinisayo zifaka isandla ekwakhiweni nasekusebenzeni kwayo yonke le mikhiqizo.
4. Izindwangu:
Embonini yendwangu, i-CMC isetshenziswa ekwenzeni usayizi, lapho inika amandla kanye nokuguquguquka kwezintambo.Iphinde isetshenziswe ekuqedeni izinqubo ukuze kwakhiwe indawo ebushelelezi futhi efanayo ezindwangu.
5. Imboni kawoyela negesi:
I-CMC isetshenziswa ekumba uketshezi embonini kawoyela negesi.Isebenza njenge-viscosifier kanye nesinciphisi sokulahlekelwa uketshezi, okunikela ekuzinzeni nasekusebenzeni koketshezi lokumba ezimeni zejoloji eziyinselele.
6. Imboni Yamaphepha:
Ekwenziweni kwamaphepha, i-CMC isetshenziswa njengosizo lokugcina nokukhipha amanzi.Ithuthukisa ukugcinwa kwezinhlayiya ezinhle, okuholela ekuthuthukisweni kwekhwalithi yephepha kanye nokusebenza kahle okwandisiwe enqubweni yokwenza iphepha.
7. Izihlanzi Nemikhiqizo Yokuhlanza:
I-CMC yengezwa ezintweni zokuhlanza kanye nemikhiqizo yokuhlanza ukuthuthukisa i-viscosity nokuzinza.Isiza ekusabalaliseni okufanayo kwezithako ezisebenzayo kanye nezinsiza ekuvimbeleni ukuhlalisa noma ukwehlukana.
8. Amapende nama-coatings:
I-CMC isetshenziswa ekwakhiweni kwamapende asekelwe emanzini kanye nama-coatings.Isebenza njenge-thickener, efaka isandla ekuvumelaneni okufunayo komkhiqizo ngesikhathi sokufaka isicelo.
Amathrendi Nezinto Ezicatshangwayo Zesikhathi esizayo:
Njengoba izimboni ziqhubeka nokuthuthuka, kukhona ukugcizelela okwandayo ezintweni ezisimeme nezingangeni emvelweni.I-Carboxymethylcellulose, etholakala emithonjeni evuselelekayo futhi ebonisa ukubola kwe-biodegradability, ihambisana nalezi zindlela.Imizamo eqhubekayo yocwaningo nentuthuko ingase igxile ekuthuthukiseni izinqubo zokukhiqiza kanye nokuhlola izicelo ezintsha ze-CMC ezimbonini ezisafufusa.
Isiphetho:
I-Carboxymethylcellulose, nenhlanganisela yayo eyingqayizivele yezakhiwo nezindlela zokusebenza kuzo zonke izimboni ezihlukahlukene, isibe ingxenye ebalulekile ekwakhiweni kwemikhiqizo eminingi.Ukusuka ekuthuthukiseni ukuthungwa kwemikhiqizo yokudla kuye ekuthuthukiseni ukusebenza kwemithi kanye nokuba negalelo kwikhwalithi yendwangu, i-CMC idlala indima enezici eziningi.Njengoba ubuchwepheshe buthuthuka kanye nesidingo sezinto ezisimeme nezisebenzayo sikhula, ukuguquguquka kwe-carboxymethylcellulose kuyibeka njengebamba elibalulekile kumhlaba wesayensi yezinto zesimanje.Ukuqamba okusha okuqhubekayo nokusebenzisana phakathi kwabacwaningi, abakhiqizi, nabasebenzisi bokugcina cishe kuzodalula amathuba amasha e-CMC, kuqinisekise ukuhambisana nokubaluleka kwayo eminyakeni ezayo.
