Njengenhlanganisela yemvelo ye-polymer, i-cellulose inezinhlobo eziningi zezicelo ekukhiqizeni. Itholakala kakhulu ezindongeni zamaseli ezitshalo futhi ingenye yamakhemikhali e-organic amaningi kakhulu emhlabeni. I-Cellulose isetshenziswe kabanzi ekukhiqizeni amaphepha, izindwangu, amapulasitiki, izinto zokwakha, imithi, ukudla kanye neminye imboni ngenxa yesakhiwo sayo esiyingqayizivele sama-molecule, ukubola okunobungani nemvelo kanye nezakhiwo zayo ezinhle kakhulu zomzimba namakhemikhali.
1. Imboni yokwenza amaphepha
Imboni yokwenza amaphepha iyinkambu eyinhloko yokusetshenziswa kwe-cellulose. Imicu yezitshalo ingenziwa ibe yi-pulp ngemva kokwelashwa ngomshini noma ngamakhemikhali. I-Cellulose inikeza amandla nokuqina njengengxenye eyinhloko kule nqubo. Enkambisweni yokwenza amaphepha, ukumuncwa kwamanzi, ukushelela kanye namandla okunamathela ephepha kungalawulwa ngokungeza izithasiselo zamakhemikhali nokusebenzisa inhlanganisela ye-fiber ehlukene. Ukuvela kwephepha eliphinde lasetshenziswa kugcizelela kakhulu ukusimama kanye nokuphinde lisetshenziswe kwe-cellulose, okwenza kube nenzuzo kakhulu ezintweni ezinobungani nemvelo.
2. Imboni yezindwangu
Imicu ye-cellulose (njengokotini) isetshenziswa kabanzi ekwenziweni kwezindwangu njengezinto eziyisisekelo zokusetshenziswa embonini yezindwangu. Imicu ye-cotton iqukethe i-cellulose engaphezu kuka-90%, okwenza ibe mnene, ibe yi-hygroscopic, ikwazi ukuphefumula nezinye izakhiwo ezinhle kakhulu, ezifanele ukwenziwa kwezinhlobo ezahlukene zezingubo. Eminyakeni yamuva nje, imicu ye-cellulose ingaphathwa ngamakhemikhali ukuze yakhe imicu ye-cellulose evuselelwe njengemicu ye-viscose kanye nemicu ye-modal, okwandisa ukusetshenziswa kwe-cellulose embonini yezindwangu. Le micu ayithambile nje kuphela futhi ikhululekile, kodwa futhi inezakhiwo ezinhle zokulwa namagciwane kanye nokubola.
3. Izinto ze-bioplastic kanye nezinto ezibolayo
I-Cellulose ingasetshenziswa ukwenza amapulasitiki abolayo embonini yamapulasitiki, okungenye yezindlela ezibalulekile zocwaningo zokuxazulula inkinga "yokungcola okumhlophe". Ngokucubungula i-cellulose ibe yi-cellulose acetate noma i-cellulose ether, ingasetshenziswa ukwenza amafilimu epulasitiki anobungani nemvelo, izitsha zokudla, njll. Lezi zinto zinokuqina kwamakhemikhali okuqinile kanye nezakhiwo zomzimba, futhi kulula ukuzibolisa endaweni yemvelo, kunciphisa umthelela wemfucuza yepulasitiki endaweni yemvelo.
4. Izinto zokwakha
Embonini yokwakha, i-cellulose isetshenziswa kabanzi ukwenza amabhodi esimende e-fiber, amabhodi e-gypsum aqiniswe nge-fiber kanye nezinto zokuvimbela ukushisa. Ukuhlanganisa imicu ye-cellulose nezinye izinto kungathuthukisa ukumelana kwayo nokushayisana, amandla okuthamba, futhi kuthuthukise ukuvimbela ukushisa kanye nokuvimbela umsindo. Isibonelo, izinto zokuvimbela ukushisa ze-cellulose ziyinto yokuvimbela ukushisa enobungani nemvelo. Ngokufaka i-cellulose powder noma izinhlayiya ze-cellulose odongeni lwesakhiwo, ingavimbela ukushisa futhi inciphise umsindo ngempumelelo, futhi izakhiwo zayo zemvelo ezingangenisi izinambuzane ziyenza isetshenziswe kabanzi ekwakheni.
5. Imboni yokudla kanye nemithi
Izinto ezisetshenziswa kuma-cellulose njenge-carboxymethyl cellulose (CMC) kanye ne-methyl cellulose (MC) nazo zibalulekile embonini yokudla neyemithi. I-Carboxymethyl cellulose isetshenziswa kabanzi njengesithambisi, isiqinisekisi kanye ne-emulsifier ekudleni, kuyilapho i-methyl cellulose ivame ukusetshenziswa njengesithambisi emathebulethini ngenxa yokunamathela kwayo okuhle kanye nokuhambisana kwayo nezinto eziphilayo. Ngaphezu kwalokho, i-cellulose ingafakwa ekudleni njenge-fiber yokudla ukusiza abantu bathuthukise impilo yamathumbu.
6. Imboni yezimonyo
I-Cellulose ivame ukusetshenziswa njengesithambisi kanye nesiqinisi ezimonyweni. Isibonelo, i-common carboxymethyl cellulose kanye ne-microcrystalline cellulose kungandisa ukujiya kanye nokuqina kwezimonyo futhi kugweme ukuhlukaniswa kwezithako. Ngaphezu kwalokho, ukubola kanye nokungabi nobuthi kwe-cellulose kwenza ifanelekele ukusetshenziswa emikhiqizweni yokuhlanza, imikhiqizo yokunakekela isikhumba kanye nezimonyo.
7. Izinto zokuhlunga ezinobungani nemvelo
Ngenxa yesakhiwo esinezimbobo kanye nokumuncwa okuhle kwe-cellulose, isetshenziswa kakhulu ezintweni zokuhlunga. Ama-membrane e-cellulose kanye nama-nanofiber e-cellulose asetshenziswa ekuhlungeni umoya, ekuphatheni amanzi kanye nasekuphatheni amanzi angcolile ezimbonini. Izinto zokuhlunga i-cellulose azikwazi nje ukususa izinhlayiya ezilengayo, kodwa futhi zimunca izinto eziyingozi, ngezinzuzo zokusebenza kahle kakhulu kanye nokuvikelwa kwemvelo. Ngaphezu kwalokho, ucwaningo lokusetshenziswa kwama-nanofiber e-cellulose lwenza kube namandla amakhulu embonini yokuhlunga kanye nokuvikelwa kwemvelo yesikhathi esizayo.
8. Insimu yamandla
I-cellulose biomass nayo idonsele ukunaka okukhulu emkhakheni wamandla. I-cellulose ingakhiqiza amandla avuselelekayo njenge-bioethanol kanye ne-biodiesel ngokubola kwe-bio kanye nokubilisa. Uma kuqhathaniswa namandla e-petrochemical, imikhiqizo yokusha yamandla e-biomass inobungani nemvelo futhi ihambisana nomqondo wentuthuko esimeme. Ubuchwepheshe bokukhiqiza be-cellulose biofuel buthuthuka kancane kancane, buhlinzeka ngamathuba amasha amandla ahlanzekile esikhathini esizayo.
9. Ukusetshenziswa kwe-nanotechnology
Ama-nanofiber e-cellulose (CNF) ayintuthuko ebalulekile ocwaningweni lwe-cellulose eminyakeni yamuva nje. Ngenxa yamandla awo aphezulu, ukuminyana okuphansi kanye nokuhambisana okuhle kwezinto eziphilayo, asetshenziswa kabanzi ezintweni ezahlukahlukene ezihlanganisiwe. Ukwengezwa kwama-nanofiber e-cellulose kungathuthukisa kakhulu izakhiwo zemishini zezinto ezihlanganisiwe, futhi uma kuqhathaniswa nezinye izinto ezihlanganisiwe, ama-nanofiber e-cellulose avuseleleka futhi abola, ngakho-ke anamandla amakhulu kumadivayisi kagesi, izinzwa, izifakelo zezokwelapha kanye nezinto ezisebenza kahle kakhulu.
10. Ubuchwepheshe bokuphrinta kanye ne-inkjet
Kubuchwepheshe bokunyathelisa kanye ne-inkjet, izinto ezisetshenziswa ku-cellulose zisetshenziselwa ukuthuthukisa ukugeleza kanye nokumuncwa kwe-ink, okwenza umphumela wokunyathelisa ufane kakhulu. Ku-inkjet yokunyathelisa i-inkjet, i-cellulose ingenza imibala igcwale futhi icace kakhudlwana. Ngaphezu kwalokho, ukucaca kanye namandla e-cellulose kungathuthukisa ikhwalithi yephepha elinyathelisiwe futhi kunciphise ukusabalala kwe-ink, ngaleyo ndlela kwenze imikhiqizo enyathelisiwe ibe sezingeni eliphezulu.
Njengezinto zemvelo ze-polymer ezivuselelekayo nezibolayo, i-cellulose isibe ngenye yezinto ezibalulekile ekukhiqizeni kwanamuhla. Ukusetshenziswa kwayo kabanzi emikhakheni ehlukene kukhombisa ukuhlukahluka kwayo kanye nokuvikelwa kwemvelo, futhi kukhuthaza ukuguqulwa okuluhlaza kwezimboni eziningi. Esikhathini esizayo, ngentuthuko eqhubekayo yesayensi nobuchwepheshe kanye nokuthuthuka kwe-cellulose nanotechnology, ukusetshenziswa kwe-cellulose kuzohlukahluka kakhulu.
