Yiziphi ukusetshenziswa kwe-cellulose embonini?

Imboni yephepha ne-Pulp:

I-Cellulose isetshenziswa kakhulu ekukhiqizeni iphepha ne-pulp. I-Wood pulp, umthombo ocebile we-cellulose, ibhekana nezinqubo ezihlukahlukene zemishini namakhemikhali ukuze kukhishwe imicu ye-cellulose, bese ibunjwa ibe imikhiqizo yephepha kusukela emaphephandabeni kuya ezintweni zokupakisha.

Imboni Yezindwangu:

Embonini yendwangu, imicu esekelwe ku-cellulose efana nekotini, i-rayon, ne-lyocell isetshenziswa kakhulu. Ukotini, osuselwa entanjeni yesitshalo sikakotini egcwele i-cellulose, uyimpahla eyinhloko yezingubo zokugqoka nezindwangu zasendlini ngenxa yokuthambile, ukuphefumula, nokumunca. I-Rayon kanye ne-lyocell, atholakala ku-cellulose ngezinqubo zamakhemikhali, anikeza ezinye izindlela kunemicu yemvelo enezinto ezifiselekayo njenge-drape, sheen, namakhono okukhipha umswakama.

Imboni Yokudla Nemithi:

I-Cellulose isebenza njengengxenye ebalulekile ekudleni okuhlukahlukene kanye nemikhiqizo yemithi. Okuphuma ku-cellulose njenge-methylcellulose ne-carboxymethylcellulose asetshenziswa njengama-thickeners, ama-stabilizer, nama-emulsifiers ekucutshungulweni kokudla. Ukwengeza, i-cellulose isetshenziswa ekwenziweni kwemithi njengesamukeli ezinhlelweni zokulethwa kwezidakamizwa, ehlinzeka ngokukhululwa okulawulwayo nokuzinza emithini.

Izinto Zokwakha Nezokwakha:

Izinto ezisekelwe ku-cellulose zithola izicelo ezimbonini zokwakha nezokwakha. Imicu ye-cellulose ihlanganiswa ezingxubeni zekhonkrithi ukuze kuthuthukiswe izici zayo zokusebenza, kunciphise ukushwabana, futhi kuthuthukise ukuqina. Ukwengeza, ukufakwa kwe-cellulose okwenziwe ngemicu yephepha esenziwe kabusha kusetshenziselwa ukufakwa kwe-thermal ne-acoustic ezakhiweni.

Ama-Biofuels namandla Avuselelekayo:

I-Cellulose isebenza njenge-feedstock yokukhiqiza ama-biofuels afana ne-bioethanol ne-biodiesel. Ngezinqubo ezifana ne-enzymatic hydrolysis kanye nokuvutshelwa, ama-cellulose polymers ahlukaniswa abe ushukela ovutshelwayo, ongaguqulwa ube ama-biofuels. I-cellulose ethanol, etholakala emithonjeni ye-biomass ecebile nge-cellulose njengezinsalela zezolimo nezitshalo zamandla, inikeza enye indlela eqhubekayo kumafutha ezinto ezimbiwa phansi.

Imikhiqizo Yokunakekela kanye Nenhlanzeko:

Okuphuma ku-cellulose kuyizithako ezibalulekile ekunakekelweni komuntu siqu kanye nemikhiqizo yenhlanzeko. Ama-cellulose ether afana ne-hydroxyethyl cellulose ne-carboxymethyl cellulose asetshenziswa ezimonyoni, ezintweni zangasese, nasezikhemisi njengama-ejenti ajiyayo, ama-emulsifiers, nabadali befilimu. Imicu ye-cellulose iphinde isetshenziswe emikhiqizweni yenhlanzeko elahlwayo njengamanabukeni namaphedi e-sanitary ngezindawo zawo zokumunca.

Imboni Yamakhemikhali:

I-Cellulose isebenza njengempahla eluhlaza yokukhiqiza amakhemikhali ahlukahlukene kanye neziphakathi. I-cellulose acetate, etholwe nge-acetylating cellulose, isetshenziswa ekwenzeni amafilimu ezithombe, izihlungi zikagwayi, nezindwangu. Ama-cellulose esters afana ne-nitrocellulose athola ukusetshenziswa kuma-lacquers, iziqhumane, nama-coatings ngenxa yezakhiwo zawo zefilimu nokunamathela.

Izicelo Zemvelo:

Izinto ezisekelwe ku-cellulose zisetshenziswa ekulungiseni imvelo nasekulawuleni imfucuza. Ama-cellulose mulch kanye nama-biofilms asiza ukuvimbela ukuguguleka kwenhlabathi futhi akhuthaze ukutshala kumaphrojekthi okubuyisela umhlaba. Ukwengeza, ama-adsorbent asekelwe ku-cellulose kanye nemidiya yokuhlunga asetshenziselwa ukwelashwa kwamanzi angcolile kanye nokuhlanza umoya, ukususa ukungcola nokungcola emifudlaneni enamanzi negesi.

Imikhiqizo Yezokwelapha Nezempilo:

Izinto ezisekelwe ku-cellulose zisetshenziswa ezinhlelweni ezihlukahlukene zezokwelapha nezokunakekelwa kwezempilo. Ulwelwesi lwe-Cellulose namafilimu asetshenziswa ekugqokeni amanxeba nasezindaweni zokuhlinza ngenxa yezakhiwo zabo ezihambisana ne-biocompatibility kanye nokugcina umswakama. Ngaphezu kwalokho, ama-scaffolds e-cellulose asetshenziswa kwezobunjiniyela bezicubu kanye nemithi evuselelayo ukusekela ukukhula kwamaseli nokuvuselelwa kwezicubu ekufakweni kwe-biomedical namadivayisi.

Izimboni zikagesi nezikagesi:

Izinto ezisekelwe ku-cellulose zisetshenziswa ezinhlelweni zikagesi nezikagesi. Ama-cellulose nanocrystals (CNCs) kanye nama-cellulose nanofibrils (CNFs) ahlanganiswe ezintweni eziyinhlanganisela yamandla awo aphezulu, angasindi, kanye nezakhiwo ze-dielectric. Lezi zinsiza zithola izinhlelo zokusebenza kumishini kagesi, amabhodi esekethe aphrintiwe, namasistimu okugcina amandla.

ukusetshenziswa kwezinto ezihlukahlukene kanye nobuningi be-cellulose kuyenza ibe insiza eyisisekelo kuzo zonke izimboni ezihlukahlukene, okunikela ekuthuthukisweni kwemikhiqizo emisha nezixazululo ezisimeme. Ukusetshenziswa kwayo okubanzi kugcizelela ukubaluleka kwayo emphakathini wanamuhla namandla ayo okuqhuba intuthuko kwezesayensi yezinto ezibonakalayo, ezobuchwepheshe, kanye nokuphathwa kwemvelo.
