Cellulose ndeye orgquitius organic compound yakawana zvakawanda muzvisikwa, kutamba basa rakakosha muzvimiro uye kushanda kwezvisikwa zvakasiyana-siyana uye zvakasikwa. Zvivakwa zvayo zvakasarudzika uye zvinopesana zvakakonzera huwandu hwakawanda hwekushandisa maindasitiri, uchiita kuti ive imwe yeanonyanya kukosha biopolymers.
1.Sources of cellulose:
Cellulose inonyanya kutorwa kubva pakudyara madziro emasero, inoshanda sechinhu cheshuwa muchimiro che microfibrils. Inowanikwa mumasero emusero emaruwa akasiyana siyana, kusanganisira huni, machira, hemp, filak, jute, nevamwe vazhinji. Aya masosi anosiyana muCellulose zvemukati uye Sangano rezvemukati, kukurudzira kukodzera kwavo kwekushandisa kwakasiyana.
Wood: huni ndeimwe yeiyo nzvimbo dzakawanda kwazvo dze cellulose, nemiti yakadai sa pine, oak, uye spruce ine huwandu hwakakosha hweiyi biopolymer iyi biopholmer. Iyo inoshanda seyakanyanya chikamu chechimiro mumasero emasero ematanda ematanda, achipa simba uye kuomarara kune chirimwa.
Cotton: Cotton Fils inoumbwa ingangoita zvese zve cellulose, ichiita kuti zvinhu zvakakosha zvigadzirwa zvekugadzira machira. Nguva yakareba, mbichana yemasero yemasero inopa simba rekubatsira, kubata, uye nekufema kwemachira ekotoni, kuzviita kwakanakira zvipfeko uye zveimba.
Hemp uye Flax: Hemp uye Flax Fress zvakare akafuma zvakare emaseru uye akashandiswa kare kugadzirwa kwemanyoro. Aya maFibles echisikigo anopa kujaira, zvinyoro-nyoro-zvinyoro-siyana zvivakwa, uye kutsigirwa kwezvakatipoteredza, kuita kuti vawedzere kuwedzeredzwa muzvinyorwa zvecoco-hushamwari.
Zvimwe zvekudyara zvirimwa: Kunze kwezvirongwa zvekutenda, cellulose inogona kubviswa kubva pane zvakasiyana-siyana zvekushandisa zvakadai se bamboo, svutugadzike, uye zvokurima zviyo, uye zvekurima zvekurima. Aya magwaro aya anobatsira pakugadzirwa kwekusimudzira kwezvigadzirwa-zvakavakirwa zvigadzirwa apo kuderedza kutsamira pane yechinyakare huni-inotorwa cellulose.
2.Properties of cellulose:
Cellulose Inoratidza Zvakawanda Zvakasarudzika Zvivakwa zvinopa kune kwayo-yakawandisa zvinyorwa zvekushandisa:
Biodegradability: Cellulose ndeye biohandura, zvinoreva kuti inogona kuputswa necrocorganisms muzvirevo zviri nyore senge carbon dioxide uye mvura. Iyi pfuma inoita cellulose-yakavakirwa zvinhu zvine hushamwari, kunyanya mukushandisa kupi kurasa uye marara ekutambisa kunetseka.
Hydrophicity: Cellulose ine yakakwirira hunhu hwemamolecules yemvura nekuda kwekuvapo kwemapoka ehydroxyl mune yayo molecular chimiro. Iyi hydrophilic yemasikirwo anogonesa cellulose-based zvigadzirwa zvekutora uye chengetedza mvura, zvichiita kuti vakwanise kunyorera zvikumbiro senge mapepa, maronda ekupfeka, uye zvigadzirwa zvehutsinye.
Simba reMuchina: Cellulose Fibers Dzine simba rakanakisa Simba, kupa kusimba uye kusimba kune zvekusimba kune zvigadzirwa zvakagadzirwa kubva kwavari. Ichi chivakwa chinonyanya kukosha mukunyoreswa kunoda kutendeka kwemamiriro ezvinhu, senge muzvinyorwa, maumbirwo, uye zvigadzirwa zvepepa.
Kuvandudzwa uye Kuchengetedza: Sechisimba chebiopolymer chinobva mumasango masango, cellulose inovandudzwa uye inotsigira. Kugadzirwa kwayo hakuvimbisi pane zvakajeka fossil mafuta zviwanikwa uye kunogona kubatsira kuCarbon kutevedzana kana akatwasuka kubva pamasango akasarudzika ekurapa uye ekurima.
3.Zviratidzo Zvekushandisa Cellulose:
Cellulose inowana zvakanyanya kushandisa maindasitiri akasiyana-siyana, nekuda kwezvivakwa zvaro zvakasiyana uye zvinowedzera:
Pepa uye kurongedza: pamwe zvinoshandiswa chaizvo zvinozivikanwa zve cellulose chiri mukugadzirwa kwepepa uye kadhibhodi. Cellulose Macheki ndiyo yakanyanya kuwanda zvinhu zvinoshandiswa mupepa, kupa chimiro chemugadziro uye hunhu hunhu hunodiwa pakunyora, kudhinda, uye kurongedza mafomu ekurongedza. Pamusoro pezvo, cellulose-based pairating zvinhu zvinopa eco-fundo dzimwe nzira dzekutengesa dzepurasitiki dzepurasitiki, dzinopa mukuedza kwekutsigira.
Zvinyoro uye Apparel: Cellulose Fibers Kubva kuCotton, Hemp, Flakhi, uye zvimwe zvekudyara zvirimwa zvakarukwa uye zvakarukwa mumachira ezvipfeko, zviumbwa zvekumba, uye maindasitiri ekushandisa. Cotton, kunyanya, inzvimbo yakashandiswa-zvakanyanya-yakavakirwa mari inisitiri yemiindaniso nekuda kwekupfava kwayo, kudzidzira, uye kuwanda. Nzvimbo dzekugadzirisa nzira dzakatungamirawo kukuvandudza kwesimba reCellulose-base Fibers senge lyocell uye modal, iro rinopa zvivakwa zvinobatsira uye zvakabatsirwa nemhoteredzo.
Biemikecal zvinhu: Cellulose-based-based-mashandisirwo emagetsi emagetsi emunda, kusanganisira kurira kwemhepo, tissue enjinjini Iyo Biocompribility uye Biodegradability yemasero inoita kuti zviite kuti zviite zvekushandisa zvakadaro, uko kubatirana neBiology Systems kwakakosha pakubata uye kuchengeteka.
Chikafu uye maindasitiri emishonga Aya maCellulose-based anowedzera kugadzirisa, uye palub kugadzikana, uye paleti kugadzikana kwezvigadzirwa zvichiratidza kuti anokwanisa kuendesa zvinodhaka uye kufanana kwemishonga mune yemishonga mafomu.
Resewable simba uye Biofuls: Cellulose-Cellulose-Yakapfuma Biemass inodhinda yekugadzirwa kwesimba rekuvandudza uye biofuls kuburikidza ne biomass designes, FERmentation, uye enzymatic hydrolysis. Cellucosic ethanol, inobva kuCellulose Degradation, inopa imwe nzira inoshamisa kune fossil kune mafuta ekutsvaga uye inobatsira kuderedza girini greenhouse gasi.
Zvigadzirwa zvemukati: Cellulose machira anoiswa mune zvigadzirwa zvekuwedzera zvekusimudzira midziyo yakadai sesimba, kuomarara, uye kukanganisa. Aya maCellulose-akavhomama macomposites anotsvaga macompass
Cellulose, seyakasikwa Biopolymer yakawanda mumadziro emasero emasero, ine midziyo yakasarudzika uye yekunyorera maindasitiri maindasitiri. Kubva pamapepa uye machekere kune biodical zvinhu uye simba rekuvandudza, cellulose rinobatsira kukurudzira kusimba uye huwandu muminda dzakasiyana siyana. Kuenderera mberi kwekutsvaga uye kufambira mberi kwehunyanzvi mukugadzirisa cellulose uye kushandisirwa kuchinjisa chivimbiso nekuwedzera zvinoshandiswa uye kugadzirisa matambudziko epasi rose zvine chekuita nekuchengetedza zvokuchengetedza uye kwekutsigira kwezvakatipoteredza. Sezvo nzanga inoramba ichikoshesa zvekutsigira uye eco-kuziva, cellense-yakavakirwa zvinhu zvakagadzirirwa kuita chiitiko chinowedzera mukuumba girini uye chingangosimba.
