I-Cellulose, enye yezinhlanganisela eziningi ze-organic Emhlabeni, isebenza njengetshe lesisekelo ezinhlotsheni ezihlukahlukene zezimboni, ezentengiselwano, nezesayensi ngenxa yezakhiwo zayo ezihlukile. Itholakala ngokuyinhloko ezindongeni zamangqamuzana ezitshalo, i-cellulose iyi-polysaccharide eyakhiwe amayunithi e-glucose ahlanganiswe ndawonye, okwenza kube i-carbohydrate eyinkimbinkimbi. Ukuguquguquka kwayo okumangalisayo, ukubola kwe-biodegradability, nokuchichima kwayo kukhuthaze inqwaba yezinhlelo zokusebenza emikhakheni eyahlukene.
Izicelo Zendabuko:
Ukukhiqizwa Kwephepha Nebhodi Lamaphepha:
Imicu ye-cellulose iyingxenye eyisisekelo yokwenziwa kwephepha namabhodi.
I-cellulose pulp etholakala ngokhuni, ukotini, noma ephepheni eligaywe kabusha iyacutshungulwa ukuze idale inqwaba yemikhiqizo yephepha, okuhlanganisa amaphephandaba, omagazini, izinto zokupakisha, nezindawo zokubhala.
Izindwangu Nezingubo:
Ukotini, ngokuyinhloko owakhiwa imicu ye-cellulose, uyinto eyisisekelo yendwangu esetshenziswa ekukhiqizeni izingubo.
Imicu ye-cellulose efana ne-rayon, i-modal, ne-lyocell akhiqizwa ngezinqubo zamakhemikhali futhi athola ukusetshenziswa kwezingubo, izindwangu zasekhaya, nemikhiqizo yezimboni.
Izinto zokwakha:
Izinto ezisekelwe ku-cellulose, njengokhuni nemikhiqizo yokhuni yobunjiniyela efana ne-plywood ne-oriented strand board (OSB), zibalulekile ekwakhiweni kohlaka, ukwahlukanisa, nokuqeda.
Imboni Yokudla:
Okuphuma ku-cellulose okufana ne-methylcellulose ne-carboxymethyl cellulose kusebenza njengama-thickeners, stabilizers, nama-bulking agents emikhiqizweni yokudla.
I-fiber yokudla ekhishwa ku-cellulose inomthelela ekwakhiweni nasekudleni ukudla okuhlukahlukene.
Ezemithi:
I-Cellulose isetshenziswa njenge-excipient ekwenziweni kwemithi, ihlinzeka ngezakhiwo ezibophayo, zokuhlakazeka, nezilawulwayo zokukhululwa kumaphilisi namaphilisi.
I-Hydroxypropyl methylcellulose (HPMC) kanye ne-microcrystalline cellulose yizinto eziphuma ku-cellulose ezivamile ezisetshenziswa emithini yemithi.
Izinhlelo zokusebenza ezisafufusa:
Amafilimu nama-Biocompatible Coatings:
I-Cellulose nanocrystals (CNCs) kanye ne-cellulose nanofibrils (CNFs) yizinhlayiya ze-cellulose ezinama-nanoscale ezinamandla akhethekile emishini kanye nezakhiwo zokuvimbela.
Lezi zinto ezisetshenziswayo ze-nanocellulose ziyahlolwa ukuze zisetshenziswe emaphaketheni angaboli, ama-coatings okudla nemithi, kanye nezingubo zokugqoka amanxeba.
Ukuphrinta kwe-3D:
Imicu ye-cellulose, etholakala ku-pulp yokhuni noma eminye imithombo ye-cellulose, isetshenziswa njengesitoko sokuphrinta kwe-3D.
I-biodegradability, ukuvuselelwa, kanye nobuthi obuphansi bemicu ye-cellulose kubenza bathandeke ekusetshenzisweni kokukhiqiza okusimeme.
Amadivayisi Okugcina Amandla:
Izinto ezisekelwe ku-cellulose ziyaphenywa ukuze zisetshenziswe kumadivayisi okugcina amandla njengama-supercapacitor namabhethri.
Izinto zekhabhoni ezitholakala ku-cellulose zibonisa izakhiwo ze-electrochemical ezithembisayo, okuhlanganisa indawo ephezulu, ukuqhutshwa kahle kukagesi, nokuqina kwemishini.
Izinhlelo zokusebenza ze-Biomedical:
Ama-scaffolds e-cellulose asetshenziswa kubunjiniyela bezicubu ekusetshenzisweni kwemithi yokuvuselela.
Izinto ezisekwe nge-biodegradable cellulose zisebenza njengabathwali bokulethwa kwezidakamizwa, izingubo zokupholisa amanxeba, nezikafula zesiko lamaseli nokuvuselelwa kwezicubu.
Ukwelashwa kwamanzi:
Ama-adsorbent asekelwe ku-cellulose asetshenziselwa ukuhlanza amanzi nokuhlanza amanzi angcolile.
Izinto eziguquliwe ze-cellulose zisusa ngempumelelo ukungcola okufana nezinsimbi ezisindayo, odayi, nokungcola kwemvelo ezixazululweni ezinamanzi ngezinqubo ze-adsorption.
I-Electronics kanye ne-Optoelectronics:
Amafilimu e-transparent conductive nama-substrates enziwe ngama-nanocrystals e-cellulose ayaphenywa ukuze asetshenziswe ku-electronics flexible kanye namadivayisi we-optoelectronic.
Izinto ezisekelwe ku-cellulose zinikeza izinzuzo ezifana nokucaca, ukuguquguquka, nokusimama uma kuqhathaniswa nezinto ezivamile ze-elekthronikhi.
Amathemba Ekusasa:
I-Bioplastics:
I-bioplastics esekelwe ku-cellulose ibambe isithembiso njengezinye izindlela ezisimeme kumapulasitiki avamile asekelwe ku-petroleum.
Imizamo iyaqhubeka yokuthuthukisa ama-polymer asuselwa ku-cellulose anezakhiwo ezithuthukisiwe zemishini, ukubola kwe-biodegradability, nezici zokucubungula ukuze zisetshenziswe kabanzi ekupakishweni, ezimpahleni zabathengi, nasezinhlelweni zezimoto.
Izinto ezihlakaniphile:
Izinto ezisetshenziswayo ze-cellulose ziyathuthukiswa njengezisetshenziswa ezihlakaniphile ezinezici zokusabela, okuhlanganisa ukukhululwa kwezidakamizwa ezisabelayo, amandla okuzilapha, kanye nokuzwa indawo ezungezile.
Lezi zinto ezithuthukisiwe ezisekelwe ku-cellulose zinezinhlelo zokusebenza ezingase zibe khona ekunakekelweni kwezempilo, amarobhothi, kanye nokuqapha kwemvelo.
I-Nanotechnology:
Ucwaningo oluqhubekayo lwezinto ze-nanocellulose, okuhlanganisa ama-cellulose nanocrystals nama-nanofibrils, kulindeleke ukuthi kuvulwe izinhlelo zokusebenza ezintsha emikhakheni efana ne-electronics, photonics, ne-nanomedicine.
Ukuhlanganiswa kwama-cellulose nanomatadium nezinye izakhi ze-nanoscale kungase kuholele kuzinto ezintsha ezixubile ezinezakhiwo eziklanyelwe izinhlelo zokusebenza ezithile.
Umnotho Oyindilinga:
Intuthuko kubuchwepheshe bokubuyisela kabusha i-cellulose kanye nezinqubo ze-biorefinery zifaka isandla ekuthuthukisweni komnotho oyindilinga wezinto ezisekelwe ku-cellulose.
Amasistimu avaliwe wokuthola kabusha nokuvuselela i-cellulose anikeza amathuba okunciphisa imfucuza, ukunciphisa umthelela wendawo, kanye nokuthuthukisa ukusebenza kahle kwezinsiza.
Ukubaluleka kwe-cellulose kudlulela ngale kwezindima zayo zendabuko ekwenzeni iphepha nezindwangu. Ngocwaningo oluqhubekayo kanye nokusungula izinto ezintsha, i-cellulose iyaqhubeka nokugqugquzela ukusetshenziswa kwenoveli kuzo zonke izimboni ezihlukahlukene, ukushayela ukusimama, ukusebenza, kanye nokusebenza kwezinto zokwakha kanye nemikhiqizo. Njengoba umphakathi uya ngokuya ubeka phambili ukunakekelwa kwemvelo nokusebenza kahle kwezinsiza, i-cellulose isalokhu iwumthombo obalulekile futhi oguquguqukayo wokubhekana nezinselele zamanje nezesikhathi esizayo.
