Cellulose chinhu chinowanikwa munzvimbo dzakawanda dzezvisikwa, chichiita basa rakakosha muchimiro nekushanda kwezvisikwa zvakasiyana-siyana. Hunhu hwayo hwakasiyana uye kushanduka-shanduka kwakaita kuti pave nekushandiswa kwakasiyana-siyana mumaindasitiri, zvichiita kuti ive imwe ye biopolymers dzinokosha.
1. Manyuko eCellulose:
Cellulose inonyanya kubva mumadziro emasero emiti, inoshanda sechinhu chechimiro muchimiro che microfibrils. Inowanikwa mumadziro emasero emiti yakasiyana-siyana, kusanganisira huni, donje, hemp, flax, jute, nezvimwe zvakawanda. Manyuko aya akasiyana muhuwandu hwe cellulose uye kurongeka kwechimiro, zvichikanganisa kukodzera kwavo kushandiswa kwakasiyana.
Matanda: Matanda ndiwo mamwe emanyuko akawanda e cellulose, miti yakaita semupaini, muouki, nemuspruce ine huwandu hwakawanda hwe biopolymer iyi. Inoshanda sechinhu chikuru chekuvaka mumadziro esero ematishu ematanda, ichipa simba uye kuomarara kuchirimwa.
Donje: Mashinda edonje anoumbwa ne cellulose chete, zvichiita kuti ave zvinhu zvinokosha pakugadzira machira. Matavi marefu, ane fibrous e cellulose anobatsira kuti machira edonje asimbiswe, anyorove, uye akwanise kufema, zvichiita kuti akwanise kushandiswa pazvipfeko nemachira epamba.
Hemp neFlax: Hemp neflax fibers zvakare manyuko akawanda e cellulose uye ave achishandiswa kare mukugadzira machira. Aya mafiber echisikigo anopa kugara kwenguva refu, hunhu hwekubvisa hunyoro, uye kuchengetedzeka kwezvakatipoteredza, zvichiita kuti awedzere kufarirwa mumachira asingakuvadzi nharaunda.
Zvimwe Zvirimwa: Kunze kwezvinhu zvataurwa pamusoro apa, cellulose inogona kutorwa kubva mune zvimwe zvinhu zvakasiyana-siyana zvezvirimwa zvakaita semhashu, masaga enzimbe, chibage stover, uye masara ekurima. Izvi zvinobatsira mukugadzirwa kwezvinhu zvakagadzirwa ne cellulose kwenguva refu uku zvichideredza kuvimba ne cellulose yetsika inobva muhuni.
2. Hunhu hweCellulose:
Cellulose ine zvinhu zvakasiyana-siyana zvinobatsira mukushandiswa kwayo kwakasiyana-siyana:
Kuora kwemasero: Cellulose inogona kuora, zvichireva kuti inogona kupatsanurwa netupukanana kuita zvinhu zviri nyore zvakaita secarbon dioxide nemvura. Izvi zvinoita kuti zvinhu zvakagadzirwa necellulose zvive zvisina njodzi kunharaunda, kunyanya mukushandiswa uko kuraswa kwemasero nekutarisira marara.
Kunyungudika kwemvura: Cellulose ine hukama hwakakura nemamorekuru emvura nekuda kwekuvapo kwemapoka ehydroxyl muchimiro chayo chemamorekuru. Hunhu uhwu hwemvura hunonyungudika hunoita kuti zvinhu zvakagadzirwa necellulose zvikwanise kunyungudika nekuchengetedza mvura, zvichiita kuti zvikodzere kushandiswa senge kugadzira mapepa, maronda, uye zvigadzirwa zvehutsanana.
Simba reMichina: Fiber dzeCellulose dzine simba remuchina rakanaka, dzichipa kugara kwenguva refu uye kusimba kwezvinhu zvakagadzirwa nadzo. Hunhu uhwu hunokosha zvikuru mukushandiswa kunoda kusimba kwechimiro, senge mumachira, zvinhu zvinosanganiswa, uye zvigadzirwa zvemapepa.
Inovandudzwa uye Inoenderera Mberi: Sechinhu chebiopolymer chechisikigo chinobva mumiti, cellulose inogona kuvandudzwa uye inogara kwenguva refu. Kugadzirwa kwayo hakutsamiri pamafuta efossil anopera uye kunogona kubatsira mukutorwa kwekabhoni kana ikawanikwa kubva mumasango anotarisirwa zvakanaka uye mumabasa ekurima.
3. Mashandisirwo akasiyana-siyana eCellulose:
Cellulose inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, nekuda kwehunhu hwayo hwakasiyana uye hunyanzvi hwayo hwekushandisa:
Pepa neKurongedza: Zvichida kushandiswa kwakanyanya kwecellulose kuri mukugadzirwa kwepepa nemakadhibhodhi. Cellulose fibers ndiyo inonyanya kushandiswa mukugadzira mapepa, ichipa chimiro chechimiro uye hunhu hwepamusoro hunodiwa pakunyora, kudhinda, uye kurongedza. Pamusoro pezvo, zvinhu zvekurongedza zvakagadzirwa ne cellulose zvinopa dzimwe nzira dzinoshanda zvakanaka kune mapurasitiki echinyakare, zvichibatsira mukuchengetedza nharaunda.
Machira Nezvipfeko: Mafiber eCellulose anobva mudonje, hemp, flax, nezvimwe zvinomera zvinorukwa kuita shinda uye zvinorukwa kana kurukwa kuita machira ezvipfeko, machira epamba, uye mashandisirwo emaindasitiri. Donje, kunyanya, ifiber inoshandiswa zvakanyanya muindasitiri yemachira nekuda kwekupfava kwayo, kufema kwayo, uye kushanduka-shanduka. Kuvandudzwa muhunyanzvi hwekugadzirisa kwakatungamirawo mukuvandudzwa kwemafiber eCellulose akadai se lyocell ne modal, ayo anopa hunhu hwakavandudzwa uye mabhenefiti ezvakatipoteredza.
Zvinhu Zvinoshandiswa Pakurapa: Zvinhu zvakagadzirwa ne cellulose zvinoshandiswawo mukurapa, kusanganisira maronda, ma tissue engineering scaffolds, ma medicine shipping systems, uye ma implants ekurapa. Kushanda pamwe chete kwe cellulose uye kuora kwayo kunoita kuti ive yakakodzera kushandiswa kwakadaro, uko kudyidzana ne biological systems kwakakosha pakushanda zvakanaka uye kuchengetedzeka.
Maindasitiri Ezvekudya Nemishonga: Zvinhu zvinobva mu cellulose zvakaita se cellulose ethers (semuenzaniso, methylcellulose, carboxymethylcellulose) uye cellulose esters (semuenzaniso, cellulose acetate, cellulose nitrate) zvinoshandiswa sezvinowedzera simba, zvinosimbisa, zvinogadzirisa, uye zvinogadzira firimu muzvikafu nemakemikari. Izvi zvinowedzera zvakagadzirwa ne cellulose zvinovandudza magadzirirwo, kugadzikana kwesherufu, uye kunaka kwezvigadzirwa zvekudya uku zvichiona kushanda kwemishonga uye kufanana kwemuyero muzvikafu.
Simba Rinodzokororwa uye Mafuta Anopa Mhuka: Mafuta anopa mhuka akawanda mu cellulose anoshanda senzvimbo yekudyara simba rinopa mhuka dzino ...
Zvinhu Zvakasanganiswa: Fibre dzecellulose dzinosanganiswa muzvinhu zvakasanganiswa kuti dziwedzere hunhu hwemakanika hwakadai sekusimba, kuomarara, uye kuramba kubatwa. Izvi zvinoshandiswa muzvinhu zvakasanganiswa zve cellulose zvinoshandiswa muzvikamu zvemotokari, zvinhu zvekuvaka, fenicha, uye zvinhu zvemitambo, zvichipa dzimwe nzira dzakareruka uye dzisingakuvadzi nharaunda pane zvinhu zvemazuva ano.
Cellulose, se biopolymer yechisikigo inowanikwa mumadziro emasero emiti, ine hunhu hwakasiyana uye mashandisirwo akasiyana-siyana mumaindasitiri. Kubva pakugadzira mapepa nemachira kusvika kuzvinhu zvekurapa uye simba rinogona kudzokororwa, cellulose inobatsira mukusimudzira nekuvandudza zvinhu munzvimbo dzakasiyana-siyana. Kuenderera mberi nekutsvaga nekufambira mberi kwetekinoroji mukugadzirisa nekushandisa cellulose kune vimbiso yekuwedzera mashandisirwo ayo uye kugadzirisa matambudziko epasi rose ane chekuita nekuchengetedzwa kwezviwanikwa uye kuchengetedza nharaunda. Sezvo nzanga ichiramba ichikoshesa kuchengetedza nharaunda uye kuziva nharaunda, zvinhu zvakagadzirwa ne cellulose zvakagadzirira kutamba basa rakakosha mukuumba remangwana rakasvibira uye rinogara kwenguva refu.
