Cellulose fiber ke eng?

Fiber ea celluloseke lintho tse nang le fiber tse nkiloeng ho cellulose, polysaccharide ea tlhaho e fumanehang maboteng a lisele tsa limela. Cellulose ke polymer e ngata ka ho fetisisa lefatšeng 'me e sebetsa e le karolo ea mantlha ea marako a lisele tsa semela, e fana ka matla, ho tiea le ho tšehetsa lisele tsa semela. Cellulose fiber e sebelisoa haholo liindastering tse fapaneng bakeng sa matla a eona, ho feto-fetoha ha maemo le ho senyeha ha lintho. Mona ke kakaretso ea fiber ea cellulose:

Mehloli ea Cellulose Fiber:

1. Lintho tsa Semela: Fiber ea cellulose haholo-holo e nkiloe mehloling ea limela, ho akarelletsa lehong, k'hothone, hemp, bamboo, jute, folaxe le bagasse ea 'moba. Mefuta e fapaneng ea limela le likarolo li na le mefuta le mefuta e fapaneng ea likhoele tsa cellulose.
2. Lisebelisoa tse Recycled: Fiber ea cellulose e ka boela ea fumanoa pampiring e tsosolositsoeng, khateboto, masela le lisebelisoa tse ling tse nang le cellulose ka mekhoa ea mechine kapa ea lik'hemik'hale.

Mekhoa ea Ts'ebetso:

1. Mechanical Pulping: Mekhoa ea mechine, e kang ho sila, ho hloekisa, kapa ho sila, e sebelisoa ho arola likhoele tsa selulose ho thepa ea semela kapa pampiri e sebelisoang hape. Mechanical pulping e boloka sebopeho sa tlhaho sa likhoele empa se ka fella ka bolelele bo khuts'oane ba fiber le bohloeki bo tlase.
2. Chemical Pulping: Mekhoa ea lik'hemik'hale, joalo ka kraft process, sulfite process, kapa organosolv process, e kenyelletsa ho phekola lisebelisoa tsa semela ka lik'hemik'hale ho qhaqha lignin le likarolo tse ling tse se nang cellulosic, ho siea likhoele tse hloekisitsoeng tsa cellulose.
3. Enzymatic Hydrolysis: Enzymatic hydrolysis e sebelisa li-enzyme ho qhetsola selulose hore e be tsoekere e qhibilihang, ebe e ka belisoa hore e be biofuel kapa lik'hemik'hale tse ling tsa biochemical.

Litšobotsi tsa Cellulose Fiber:

1. Matla: Likhoele tsa cellulose li tsejoa ka matla a tsona a phahameng a ho tsitsa, ho satalla, le ho tšoarella, ho etsa hore li tšoanelehe bakeng sa ts'ebetso ea meralo liindastering tse fapaneng.
2. Absorbency: Lithapo tsa cellulose li na le matla a ho monya hantle, tse li lumellang ho monya le ho boloka mongobo, maro le monko. Sena se etsa hore e be tse loketseng bakeng sa ho sebelisoa linthong tse monyang, tse kang lithaole tsa pampiri, li-wipes le lihlahisoa tsa bohloeki.
3. Ho senyeha ha 'mele: Fiber ea cellulose e khona ho bola 'me e baballa tikoloho, kaha e ka aroloa ke likokoana-hloko hore e be lintho tse se nang kotsi, tse kang metsi, carbon dioxide le lintho tse phelang.
4. Thermal Insulation: Lithaele tsa cellulose li na le thepa ea tlhaho ea ho futhumatsa mocheso, e li etsang hore li tšoanelehe ho sebelisoa ha ho etsoa lihlahisoa tsa moaho, joalo ka selulose sa cellulose, se thusang ho ntlafatsa ts'ebetso ea matla le ho fokotsa litšenyehelo tsa ho futhumatsa le ho pholisa.
5. Chemical Reactivity: Lithaele tsa cellulose li ka kena phetohong ea lik'hemik'hale ho hlahisa lihlopha tse sebetsang kapa ho fetola thepa ea tsona bakeng sa lits'ebetso tse ikhethileng, joalo ka li-cellulose ethers, esters, le li-derivatives tse sebelisoang meriana, li-additives tsa lijo le lits'ebetso tsa indasteri.

Lisebelisoa tsa Cellulose Fiber:

1. Pampiri le Pakete: Fiber ea cellulose ke eona ntho e ka sehloohong e tala bakeng sa ho etsa pampiri, e sebelisetsoang ho hlahisa lihlahisoa tse fapaneng tsa pampiri le tsa karete, ho kenyeletsoa pampiri ea khatiso, thepa ea ho paka, pampiri ea lithane le boto ea masenke.
2. Masela le Liaparo: Likhoele tsa cellulose, tse kang k’hothone, line le rayon (viscose), li sebelisoa ha ho etsoa masela ho etsa masela, likhoele le thepa ea liaparo, ho akarelletsa lihempe, mese, li-jeans le lithaole.
3. Lisebelisoa tsa Kaho: Fiber ea cellulose e sebelisoa ha ho etsoa lihlahisoa tsa lehong tse entsoeng ka boenjiniere, joalo ka particleboard, fiberboard, oriented strand board (OSB), le plywood, hammoho le lisebelisoa tsa ho kenya letsoho le lisebelisoa tsa konkreite.
4. Li-Biofuel le Matla: Fiber ea cellulose e sebetsa e le phepelo bakeng sa tlhahiso ea biofuel, ho kenyeletsoa ethanol, biodiesel, le biomass pellets, hammoho le limela tse kopanyang mocheso le ho fehla matla.
5. Lijo le Meriana: Li-cellulose derivatives, tse kang methylcellulose, carboxymethylcellulose (CMC), le microcrystalline cellulose (MCC), li sebelisoa e le li-thickeners, stabilizers, binders, le li-filler lihlahisoa tsa lijo, meriana, litlolo, le lintho tsa tlhokomelo ea botho.

Qetello:

Cellulose fiber ke sesebelisoa se sebetsang ka mokhoa o fapaneng le se tšoarellang se nang le lits'ebetso tse fapaneng ho pholletsa le liindasteri, ho kenyeletsoa ho etsa pampiri, masela, kaho, biofuel, lijo le meriana. Bongata ba eona, e nchafalitsoeng, le ho senyeha ha eona ho etsa hore e be khetho e khahlehang bakeng sa bahlahisi ba batlang lisebelisoa tse sebetsang hantle tikolohong le tse sebetsang hantle. Ha liindasteri li ntse li tsoela pele ho beha ka sehloohong botsitso le tlhokomelo ea tikoloho, fiber ea cellulose e lebeletsoe ho ba le karolo ea bohlokoa phetohong ea moruo o pota-potileng le o sebetsang hantle ka lisebelisoa.
