Iyini i-cellulose esetshenziselwa ukukhiqiza?

Njengenhlanganisela ye-polymer yemvelo, i-cellulose inezinhlobonhlobo zezicelo ekukhiqizeni. Itholakala ikakhulukazi ezindongeni zamangqamuzana ezitshalo futhi ingenye yezinto eziphilayo ezitholakala ngobuningi emhlabeni. I-cellulose isetshenziswe kakhulu ekukhiqizeni amaphepha, izindwangu, amapulasitiki, izinto zokwakha, imithi, ukudla nezinye izimboni ngenxa yesakhiwo sayo esiyingqayizivele samangqamuzana, ukuwohloka kwemvelo kanye nezakhiwo ezinhle kakhulu zomzimba namakhemikhali.

 

1. Imboni yokwenza amaphepha

Imboni yokwenza iphepha iyinsimu eyinhloko yokusetshenziswa kwe-cellulose. Imicu yezitshalo ingenziwa ibe yi-pulp ngemva kokwelashwa ngomshini noma ngamakhemikhali. I-Cellulose inikeza amandla nokuqina njengengxenye eyinhloko kule nqubo. Enqubweni yokwenza iphepha, ukumuncwa kwamanzi, ukushelela kanye namandla aqinile ephepha kungalawulwa ngokungeza izithasiselo zamakhemikhali nokusebenzisa inhlanganisela yefiber ehlukene. Ukuvela kwephepha eligaywe kabusha kuphinde kugcizelele ukusimama kanye nokugaywa kabusha kwe-cellulose, okulenza libe nenzuzo kakhulu ezintweni ezithinta imvelo.

 

2. Imboni yezindwangu

Imicu ye-cellulose (efana nekotini) isetshenziswa kakhulu ekwenzeni izindwangu njengezisetshenziswa eziyisisekelo zomkhakha wendwangu. Izintambo zikakotini ziqukethe i-cellulose engaphezu kuka-90%, okwenza kube lula, i-hygroscopic, ukuphefumula kanye nezinye izakhiwo ezinhle kakhulu, ezifanele ukwenziwa kwezinhlobo ezihlukahlukene zezingubo. Eminyakeni yamuva nje, imicu ye-cellulose ingalashwa ngamakhemikhali ukuze yenze imicu ye-cellulose evuselelwe njengemicu ye-viscose nemicu ye-modal, okuqhubeka nokwandisa ukusetshenziswa kwe-cellulose embonini yendwangu. Le micu ayigcini nje ngokuthambile futhi inethezekile, kodwa futhi inezindawo ezinhle zokulwa namagciwane kanye ne-biodegradable.

 

3. I-Bioplastics nezinto ezingaboli

I-Cellulose ingasetshenziswa ukwenza amapulasitiki angaboli embonini yepulasitiki, okungenye yezinkomba ezibalulekile zocwaningo zokuxazulula inkinga "yokungcoliswa okumhlophe". Ngokucubungula i-cellulose ibe yi-cellulose acetate noma i-cellulose ether, ingasetshenziswa ukwenza amafilimu epulasitiki e-eco-friendly, i-tableware, njll. Lezi zinto zinokuqina okuqinile kwamakhemikhali kanye nezakhiwo ezibonakalayo, futhi kulula ukuwohloka endaweni yemvelo, ukunciphisa umthelela imfucuza yepulasitiki endaweni yemvelo.

 

4. Izinto zokwakha

Embonini yezokwakha, i-cellulose isetshenziswa kabanzi ukwenza amabhodi osimende we-fiber, amabhodi e-gypsum aqiniswe nge-fiber kanye nezinto zokushisa ezishisayo. Ukuhlanganisa imicu ye-cellulose nezinye izinto kungathuthukisa ukumelana nomthelela wawo, amandla aqinile, futhi kuthuthukise ukufakwa kwe-thermal kanye nokuvala umsindo. Isibonelo, i-cellulose thermal insulation material iyinto ehambisana nemvelo yokushisa ukushisa. Ngokufaka i-cellulose powder noma izinhlayiya ze-cellulose odongeni lwesakhiwo, ingakwazi ukufaka insulate ngokuphumelelayo futhi inciphise umsindo, futhi izakhiwo zayo zemvelo zokuvikela izinambuzane ziyenza isetshenziswe kabanzi ekwakheni.

 

5. Imboni yokudla neyokwenza imithi

Okuphuma ku-cellulose okufana ne-carboxymethyl cellulose (CMC) kanye ne-methyl cellulose (MC) nakho kunezinhlelo zokusebenza ezibalulekile ezimbonini zokudla nezamakhemisi. I-Carboxymethyl cellulose isetshenziswa kakhulu njenge-thickener, stabilizer kanye ne-emulsifier ekudleni, kuyilapho i-methyl cellulose ivame ukusetshenziswa njenge-disintegrant kumaphilisi ngenxa yokunamathela kwayo okuhle kanye nokuvumelana kwe-biocompatibility. Ngaphezu kwalokho, i-cellulose ingabuye yengezwe ekudleni njenge-fiber yokudla ukusiza abantu ukuthuthukisa impilo yamathumbu.

 

6. Imboni yezimonyo

I-Cellulose ivame ukusetshenziswa njenge-thickener kanye ne-stabilizer ezimonyoni. Isibonelo, i-carboxymethyl cellulose evamile kanye ne-microcrystalline cellulose ingakhuphula i-viscosity nokuzinza kwezimonyo futhi igweme ukuhlukaniswa kwezithako. Ukwengeza, ukuwohloka nokungewona ubuthi be-cellulose kuyenza ifanele ukusetshenziswa emikhiqizweni yokuhlanza, imikhiqizo yokunakekelwa kwesikhumba kanye nezimonyo.

 

7. Izinto ezihambisana nemvelo kanye nezinto zokuhlunga

Ngenxa yesakhiwo esinama-porous kanye ne-adsorption enhle ye-cellulose, isetshenziswa kakhulu ezintweni zokuhlunga. Ama-cellulose membranes nama-cellulose nanofibers asetshenziswa ekuhlungeni komoya, ekwelapheni amanzi nasekuhlanzeni amanzi angcolile ezimbonini. Izinto zokuhlunga i-cellulose azikwazi nje ukususa izinhlayiya ezimisiwe, kodwa futhi zikhangisa izinto eziyingozi, ngezinzuzo zokusebenza kahle okuphezulu nokuvikelwa kwemvelo. Ngaphezu kwalokho, ucwaningo lokusetshenziswa kwe-cellulose nanofibers luyenza ibe namandla amakhulu ezimbonini zokuhlunga nezokuvikela imvelo esizayo.

 

8. Inkambu yamandla

I-cellulose biomass nayo idonse ukunaka okukhulu emkhakheni wamandla. I-Cellulose ingakhiqiza amandla avuselelekayo njenge-bioethanol ne-biodiesel ngokusebenzisa i-biodegradation kanye nokuvutshelwa. Uma kuqhathaniswa namandla e-petrochemical, imikhiqizo evuthayo yamandla e-biomass inobungani bemvelo futhi ihambisana nomqondo wentuthuko esimeme. Ubuchwepheshe bokukhiqiza be-cellulose biofuel buthuthuka kancane kancane, buhlinzeka ngamathuba amasha wamandla ahlanzekile esikhathini esizayo.

 

9. Ukusetshenziswa kwe-nanotechnology

I-Cellulose nanofibers (CNF) iyinqubekelaphambili ebalulekile ocwaningweni lwe-cellulose eminyakeni yamuva nje. Ngenxa yamandla abo aphezulu, ukuminyana okuphansi kanye nokuvumelana okuhle kwe-biocompatibility, asetshenziswa kabanzi ezintweni eziyinhlanganisela ezihlukahlukene. Ukwengezwa kwe-cellulose nanofibers kungathuthukisa kakhulu izakhiwo zemishini yezinto ezihlanganisiwe, futhi uma kuqhathaniswa namanye ama-nanomaterials, i-cellulose nanofibers ivuseleleka futhi i-biodegradable, ngakho-ke inamandla amakhulu emishini kagesi, izinzwa, izimila zezokwelapha kanye nezinto ezisebenza kahle kakhulu.

 

10. Ubuchwepheshe bokuphrinta kanye ne-inkjet

Ebuchwephesheni bokuphrinta ne-inkjet, okuphuma ku-cellulose kusetshenziselwa ukuthuthukisa uketshezi kanye nokukhangiswa koyinki, okwenza umphumela wokuphrinta ufane kakhulu. Koyinki wokuphrinta we-inkjet, i-cellulose ingenza imibala igcwale futhi icace. Ngaphezu kwalokho, ukucaca namandla e-cellulose kungathuthukisa ikhwalithi yephepha eliphrintiwe futhi kunciphise ukusabalalisa kukayinki, ngaleyo ndlela kwenze imikhiqizo ephrintiwe ibe yekhwalithi ephezulu.

 

Njengempahla ye-polymer yemvelo evuselelekayo futhi eyonakalayo, i-cellulose isiphenduke enye yezinto ezibalulekile ekukhiqizeni kwanamuhla. Ukusetshenziswa kwayo okubanzi emikhakheni ehlukene kukhombisa ukuhlukahluka kwayo kanye nokuvikelwa kwemvelo, futhi ikhuthaza ukuguqulwa okuluhlaza kwezimboni eziningi. Esikhathini esizayo, ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe kanye nempumelelo ye-cellulose nanotechnology, ukusetshenziswa kwe-cellulose kuzohlukahluka kakhulu.
