Njengengxenye yemvelo ye-polymer, i-cellulose inezicelo ezahlukahlukene zokukhiqiza. Kuthathwe ikakhulukazi kusuka ezindongeni zeseli zezitshalo futhi kungenye yezinto eziningi ze-organic emhlabeni. I-cellulose isetshenziswe kabanzi ekukhiqizeni kwamaphepha, izindwangu, amapulasitiki, izinto zokwakha, umuthi, ukudla kanye nezinye izimboni ngenxa yesakhiwo sayo esiyingqayizivele, ukulimala okuhle kwemvelo kanye nezinto ezinhle kakhulu zomzimba kanye namakhemikhali.
1. Umkhakha we-papermaking
Umkhakha we-papermaking yinkambu yesicelo esiyinhloko yeselula. Imicu yezitshalo ingenziwa nge-pulp ngemuva kokwelashwa kwemishini noma kwamakhemikhali. I-Cellulose inikeza amandla nokuqina njengengxenye eyinhloko kule nqubo. Enqubweni yokuphamba, ukumuncwa kwamanzi, ubushelelezi kanye namandla ashubile ephepha kungalawulwa ngokungeza izithasiselo zamakhemikhali nokusebenzisa inhlanganisela ehlukile ye-fiber. Ukuvela kwephepha eliphindaphindwayo kugcizelela kakhulu ukuqina nokuphinda ubuyekezeke kwe-cellulose, okwenza kube nenzuzo enkulu ezintweni ezinobungane bemvelo.
2 Imboni Yendwangu
I-cellulose fibers (efana nokotini) isetshenziswa kabanzi ekwakheni izindwangu njengezinto eziyisisekelo zokusetshenziswa komkhakha wezindwangu. Imicu yekottotton iqukethe ngaphezu kwe-90% celtulose, ebenza bathambe, i-hygroscopic, ephefumula kanye nezinye izakhiwo ezinhle kakhulu, zilungele ukwenziwa kwezinhlobo ezahlukahlukene zezingubo. Eminyakeni yamuva nje, ama-cellulose fibers angaphathwa ngamakhemikhali ukwakha imicu ye-cellulose ebizwa nge-viscose fibers nemicu emihle, ukunwebeka ngokuqhubekayo ukusetshenziswa kwe-cellulose embonini yezindwangu. Le micu ayithatha nje kuphela futhi inethezekile, kepha futhi inezakhiwo ezinhle ze-antibacterial ne-biodegradable.
3. Ama-Bioplastics nezinto zokwakha ezingathandeki
I-cellulose ingasetshenziselwa ukwenza amapulasitiki angenakusebenza embonini yePlastics, okungenye yezinkomba ezibalulekile zokucwaninga zokuxazulula inkinga 'yokungcoliswa okumhlophe'. Ngokucubungula iselula ku-cellulose acetate noma i-cellulose ether, ingasetshenziswa ukwenza amafilimu epulasitiki anobungane, i-Tableware, njll. Lezi zinto zokwakha zinokuqina okuqinile kwamakhemikhali kanye nezinto ezibonakalayo, futhi kulula ukungcola endaweni yemvelo, kunciphisa umthelela we imfucuza yepulasitiki endaweni yemvelo.
4. Izinto zokwakha
Embonini yezokwakha, i-cellulose isetshenziswa kabanzi ukwenza amabhodi kasifu we-fiber, amabhodi we-gypsum aqinisiwe we-gypsum kanye nezinto zokwehlukanisa okushisayo. Ukuhlanganisa imicu ye-cellulose nezinye izinto zokwakha kungathuthukisa ukumelana nomthelela kwazo, amandla ashubile, futhi kuthuthukiswe ukufakwa okushisayo kanye nokufakwa okuzwakalayo. Isibonelo, i-CelLelose Theral I-Insulal Infation Material iyinto enobungane bokufakwa kwemvelo kwemvelo. Ngokufaka i-cellulose powder noma izinhlayiya ze-cellulose odongeni lokwakha, zingafaka ngempumelelo futhi zinciphise umsindo, kanye nezakhiwo zayo zemvelo zobufakazi besinambuzane zikwenza kusetshenziswe kabanzi ekwakhiweni.
5. Imboni yokudla nezemithi
I-Cellulose Derivatives efana ne-carboxymethyl cellulose (CMC) ne-methyl cellulose (MC) futhi zinezicelo ezibalulekile ezimbonini zokudla kanye nemithi. I-Carboxymethyl Cellulose isetshenziswa kabanzi njengomuntu omkhulu, i-stabilizer kanye ne-emulsifier ekudleni, ngenkathi i-methyl cellulose ivame ukusetshenziswa njenge-ukuqhekeka ezibhebheni ngenxa yokunamathela kwayo okuhle. Ngaphezu kwalokho, i-cellulose ingangezwa futhi ekudleni njenge-fiber yokudla ukusiza abantu bathuthukise impilo yamathumbu.
6. Imboni yezimonyo
I-cellulose ivame ukusetshenziswa njenge-sikhulu ne-stibilizer ezimotweni. Isibonelo, i-carbox mileboxylyllline cellulose kanye ne-microcrystalline celtule Ngaphezu kwalokho, ukuwohloka nokungezwani nobuthi be-cellulose kwenza kube lula ukusetshenziswa emikhiqizweni yokuhlanza, imikhiqizo yokunakekelwa kwesikhumba kanye nokwenza izimonyo.
7. Izinto zokwakha imvelo nezinto zokuhlunga
Ngenxa yesakhiwo se-porous kanye ne-adsorption enhle ye-cellulose, iyanda kakhulu ezintweni zokuhlunga. I-cellulose membranes kanye nama-cellulose nanofibers asetshenziswa ekuhlutjweni komoya, ukwelashwa kwamanzi kanye nokwelashwa kwamanzi ezimboni. Izinto zokuhlunga ze-cellulose azikwazi ukususa izinhlayiya ezimisiwe kuphela, kodwa futhi nezinto eziyingozi eziyingozi, nezinzuzo zokusebenza kahle nokuvikelwa kwemvelo. Ngaphezu kwalokho, ukucwaninga kohlelo lokusebenza lwe-cellulose nanofibers kwenza kube namandla amakhulu kuFiltration and Vaitervice Environment Vaker.
8. Insimu yamandla
I-Cellulose Biomass nayo idonsele ukunakwa kakhulu enkambu yamandla. I-cellulose ingakhiqiza amandla avuselelekayo anjenge-bioethanol ne-biodieseel nge-biodegradation kanye nokuvutshelwa. Uma kuqhathaniswa namandla e-petrochemical, imikhiqizo yokuhlanganisa ye-biomass energy inobungani bemvelo futhi ihambisana nomqondo wentuthuko esimeme. Ubuchwepheshe bokukhiqiza be-cellulose biofuel buthuthuka kancane kancane, ukuhlinzeka amathuba amasha amandla ahlanzekile ngokuzayo.
9. Ukusetshenziswa kwe-nanotechnology
I-Cellulose Nanofibers (CNF) iyinqubekela phambili ebalulekile eCellulose Construction eminyakeni yamuva. Ngenxa yamandla abo aphezulu, ubuningi obuphansi nokuba buthaka okuhle, kusetshenziswa kabanzi ezindaweni ezahlukahlukene eziyinhlanganisela. Ukungezwa kwe-cellulose nanofibers kungathuthukisa kakhulu izakhiwo zemishini zezinto zokwakha ezihlanganisiwe, futhi uma kuqhathaniswa namanye ama-nanomatadium, izinzwa, ukufakwa kwe-mines, izinzwa, izici zezokwelapha kanye nezinto zokwenza umsebenzi aphezulu.
10. Ubuchwepheshe bokuphrinta nobungcweti be-inkjet
Kubuchwepheshe bokuphrinta nobunyonishi, kusetshenziselwa ukufundwa kwe-cellulose ukuthuthukisa uketshezi kanye ne-adsorption yama-inks, okwenza umphumela wokuphrinta umfaniswano ongeziwe. Ku-inkjet yokuphrinta ama-inks, iselula kungenza imibala igcwele futhi icace. Ngaphezu kwalokho, ukucaca kanye namandla e-cellulose kungathuthukisa ikhwalithi yephepha eliphrintiwe futhi kunciphise ukufakwa kwe-ink, ngaleyo ndlela okwenza imikhiqizo ephrintiwe yekhwalithi ephezulu.
Njenge-polymer evuselelekayo nenokonakala yemvelo yemvelo, i-cellulose isiphenduwe ngenye yezinto ezibalulekile ekukhiqizweni kwesimanje. Uhlelo lwayo olubanzi emikhakheni ehlukene lukhombisa ukuhlukahluka kwalo nokuvikelwa kwemvelo, futhi kuthuthukisa ukuguqulwa okuluhlaza kwezimboni eziningi. Ngokuzayo, ukuthuthukiswa okuqhubekayo kwesayensi nobuchwepheshe kanye ne-ekrough of cellulose nanotechnology, ukusetshenziswa kwe-cellulose kuzokwahluka ngokwengeziwe.
