Monga mankhwala achilengedwe a polima, cellulose imagwiritsidwa ntchito kwambiri popanga zinthu. Imachokera makamaka ku makoma a maselo a zomera ndipo ndi imodzi mwa mankhwala achilengedwe ambiri padziko lapansi. Cellulose yagwiritsidwa ntchito kwambiri popanga mapepala, nsalu, mapulasitiki, zipangizo zomangira, mankhwala, chakudya ndi mafakitale ena chifukwa cha kapangidwe kake kapadera ka mamolekyu, kuwonongeka kosawononga chilengedwe komanso mphamvu zake zabwino kwambiri zakuthupi ndi zamakemikolo.
1. Makampani opanga mapepala
Makampani opanga mapepala ndiye gawo lalikulu la ntchito ya cellulose. Ulusi wa zomera ukhoza kupangidwa kukhala zamkati pambuyo pa kukonza makina kapena mankhwala. Cellulose imapereka mphamvu ndi kulimba ngati gawo lalikulu la njirayi. Pakupanga mapepala, kuyamwa kwa madzi, kusalala ndi mphamvu yokoka kwa pepala kumatha kulamulidwa powonjezera zowonjezera za mankhwala ndikugwiritsa ntchito mitundu yosiyanasiyana ya ulusi. Kutuluka kwa mapepala obwezerezedwanso kumagogomezeranso kukhazikika ndi kubwezeretsanso kwa cellulose, zomwe zimapangitsa kuti ikhale yopindulitsa kwambiri pazinthu zosawononga chilengedwe.
2. Makampani opanga nsalu
Ulusi wa cellulose (monga thonje) umagwiritsidwa ntchito kwambiri popanga nsalu ngati zinthu zofunika kwambiri pamakampani opanga nsalu. Ulusi wa thonje uli ndi cellulose yoposa 90%, zomwe zimapangitsa kuti ikhale yofewa, yosalala, yopumira komanso yabwino kwambiri, yoyenera kupanga mitundu yosiyanasiyana ya zovala. M'zaka zaposachedwa, ulusi wa cellulose ukhoza kukonzedwa ndi mankhwala kuti upange ulusi wa cellulose wobwezeretsedwanso monga ulusi wa viscose ndi ulusi wa modal, zomwe zikukulitsa kugwiritsa ntchito cellulose mumakampani opanga nsalu. Ulusi uwu si wofewa komanso womasuka kokha, komanso uli ndi mphamvu zabwino zotsutsana ndi mabakiteriya komanso zowola.
3. Mapulasitiki achilengedwe ndi zinthu zomwe zimawola
Cellulose ingagwiritsidwe ntchito kupanga mapulasitiki ovunda m'makampani opanga mapulasitiki, yomwe ndi imodzi mwa njira zofunika kwambiri zofufuzira zothetsera vuto la "kuipitsidwa koyera". Mwa kukonza cellulose kukhala cellulose acetate kapena cellulose ether, ingagwiritsidwe ntchito kupanga mafilimu apulasitiki ochezeka ndi chilengedwe, mbale zodyera, ndi zina zotero. Zipangizozi zimakhala ndi kukhazikika kwamphamvu kwa mankhwala komanso zinthu zakuthupi, ndipo ndizosavuta kuwonongeka m'chilengedwe, zomwe zimachepetsa mphamvu ya zinyalala za pulasitiki pa chilengedwe.
4. Zipangizo zomangira
Mu makampani omanga, cellulose imagwiritsidwa ntchito kwambiri popanga matabwa a simenti a ulusi, matabwa a gypsum olimbikitsidwa ndi ulusi ndi zipangizo zotetezera kutentha. Kuphatikiza ulusi wa cellulose ndi zinthu zina kungathandize kupirira kugwedezeka, mphamvu yokoka, komanso kukonza kutetezedwa kwa kutentha ndi kutetezedwa kwa phokoso. Mwachitsanzo, zinthu zotetezera kutentha za cellulose ndi zinthu zotetezera kutentha zomwe siziwononga chilengedwe. Mwa kulowetsa ufa wa cellulose kapena tinthu ta cellulose pakhoma la nyumba, zimatha kuteteza bwino ndikuchepetsa phokoso, ndipo mphamvu zake zachilengedwe zopewera tizilombo zimapangitsa kuti zigwiritsidwe ntchito kwambiri pomanga.
5. Makampani ogulitsa zakudya ndi mankhwala
Zinthu zochokera ku cellulose monga carboxymethyl cellulose (CMC) ndi methyl cellulose (MC) zimagwiritsidwanso ntchito kwambiri m'makampani azakudya ndi mankhwala. Carboxymethyl cellulose imagwiritsidwa ntchito kwambiri ngati chokhuthala, chokhazikika komanso chosakaniza chakudya, pomwe methyl cellulose nthawi zambiri imagwiritsidwa ntchito ngati chosakaniza m'mapiritsi chifukwa cha kumamatira bwino komanso kugwirizana kwake ndi zinthu zina. Kuphatikiza apo, cellulose imatha kuwonjezeredwa ku chakudya ngati ulusi wazakudya kuti ithandize anthu kukhala ndi thanzi labwino m'matumbo.
6. Makampani opanga zodzoladzola
Cellulose nthawi zambiri imagwiritsidwa ntchito ngati chokhuthala komanso chokhazikika mu zodzola. Mwachitsanzo, cellulose ya carboxymethyl ndi microcrystalline cellulose zimatha kuwonjezera kukhuthala ndi kukhazikika kwa zodzoladzola ndikupewa kugawa zosakaniza. Kuphatikiza apo, kuwonongeka ndi kusaopsa kwa cellulose kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zotsuka, zosamalira khungu komanso zodzoladzola.
7. Zipangizo zosawononga chilengedwe ndi zinthu zosefera
Chifukwa cha kapangidwe kake kokhala ndi mabowo komanso kulowetsedwa bwino kwa cellulose, ikugwiritsidwa ntchito kwambiri mu zinthu zosefera. Ma cellulose membranes ndi cellulose nanofibers amagwiritsidwa ntchito posefera mpweya, kuyeretsa madzi ndi kuyeretsa madzi otayidwa m'mafakitale. Zipangizo zosefera za cellulose sizimangochotsa tinthu tomwe timapachikidwa, komanso zimasefera zinthu zoopsa, zomwe zimapangitsa kuti zikhale zogwira mtima kwambiri komanso kuteteza chilengedwe. Kuphatikiza apo, kafukufuku wogwiritsa ntchito cellulose nanofibers umapangitsa kuti ikhale ndi kuthekera kwakukulu m'mafakitale osefera ndi kuteteza chilengedwe mtsogolo.
8. Mphamvu
Cellulose biomass yakopanso chidwi chachikulu m'munda wa mphamvu. Cellulose imatha kupanga mphamvu zongowonjezwdwanso monga bioethanol ndi biodiesel kudzera mu biodegradation ndi fermentation. Poyerekeza ndi mphamvu ya petrochemical, zinthu zoyaka za mphamvu ya biomass ndizosawononga chilengedwe ndipo zimagwirizana ndi lingaliro la chitukuko chokhazikika. Ukadaulo wopanga cellulose biofuel ukukwera pang'onopang'ono, zomwe zikupereka mwayi watsopano wa mphamvu zoyera mtsogolo.
9. Kugwiritsa ntchito nanotechnology
Ma cellulose nanofibers (CNF) ndi kupita patsogolo kofunikira pa kafukufuku wa cellulose m'zaka zaposachedwa. Chifukwa cha mphamvu zawo zambiri, kuchepa kwa kachulukidwe kawo komanso kusagwirizana bwino kwa zinthu zachilengedwe, amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zophatikizika. Kuwonjezera ma cellulose nanofibers kumatha kusintha kwambiri mawonekedwe a makina a zinthu zophatikizika, ndipo poyerekeza ndi zinthu zina zophatikizika, ma cellulose nanofibers amatha kubwezeretsedwanso komanso kuwonongeka, kotero ali ndi kuthekera kwakukulu pazida zamagetsi, masensa, zida zamankhwala komanso zinthu zogwira ntchito bwino.
10. Ukadaulo wosindikiza ndi inkjet
Mu ukadaulo wosindikiza ndi inkjet, zinthu zochokera ku cellulose zimagwiritsidwa ntchito kuti ziwongolere kusinthasintha ndi kulowetsedwa kwa inki, zomwe zimapangitsa kuti kusindikiza kukhale kofanana. Mu inki yosindikiza inkjet, cellulose ingapangitse mitundu kukhala yodzaza komanso yomveka bwino. Kuphatikiza apo, kuwonekera bwino ndi mphamvu ya cellulose zingathandize kuti mapepala osindikizidwa akhale abwino komanso kuchepetsa kufalikira kwa inki, motero zimapangitsa kuti zinthu zosindikizidwa zikhale zapamwamba kwambiri.
Monga chinthu chachilengedwe chobwezerezedwanso komanso chowonongeka, cellulose yakhala imodzi mwa zipangizo zofunika kwambiri popanga zinthu zamakono. Kugwiritsa ntchito kwake kwakukulu m'magawo osiyanasiyana kukuwonetsa kusiyanasiyana kwake komanso kuteteza chilengedwe, ndipo kumalimbikitsa kusintha kobiriwira kwa mafakitale ambiri. M'tsogolomu, ndi chitukuko chopitilira cha sayansi ndi ukadaulo komanso kupita patsogolo kwa nanotechnology ya cellulose, kugwiritsa ntchito cellulose kudzakhala kosiyanasiyana kwambiri.
