Cellulose fiber yog dab tsi?

Cellulose fiber ntauyog cov khoom siv fiber ntau tau los ntawm cellulose, ib txwm tshwm sim polysaccharide pom nyob rau hauv cell phab ntsa ntawm cov nroj tsuag. Cellulose yog cov organic polymer ntau tshaj plaws nyob rau hauv lub ntiaj teb thiab ua lub luag haujlwm tseem ceeb ntawm cov phab ntsa ntawm cov nroj tsuag, muab lub zog, rigidity, thiab txhawb nqa cov ntaub so ntswg. Cellulose fiber yog dav siv nyob rau hauv ntau yam lag luam rau nws lub zog, versatility, thiab biodegradability. Ntawm no yog cov ntsiab lus ntawm cellulose fiber ntau:

Qhov chaw ntawm Cellulose Fiber:

1. Cog Khoom: Cellulose fiber ntau yog muab los ntawm cov nroj tsuag, suav nrog ntoo, paj rwb, hemp, xyoob, jute, flax, thiab qab zib bagasse. Ntau hom nroj tsuag thiab qhov chaw muaj ntau qhov sib txawv thiab hom cellulose fibers.
2. Recycled Materials: Cellulose fiber kuj tuaj yeem tau txais los ntawm cov ntawv siv dua tshiab, cov duab los qhia, textiles, thiab lwm yam cellulose-muaj cov ntaub ntawv pov tseg los ntawm kev siv tshuab lossis tshuaj.

Cov txheej txheem ua:

1. Mechanical Pulping: Cov txheej txheem siv tshuab, xws li kev sib tsoo, kho kom zoo, lossis milling, yog siv los cais cov cellulose fibers los ntawm cov khoom cog los yog cov ntawv siv dua. Mechanical pulping khaws cia lub ntuj tsim ntawm cov fibers tab sis yuav ua rau luv fiber ntev thiab qis purity.
2. Tshuaj Pulping: Cov txheej txheem tshuaj, xws li cov txheej txheem kraft, txheej txheem sulfite, lossis txheej txheem organosolv, koom nrog kev kho cov khoom cog nrog cov tshuaj kom yaj lignin thiab lwm yam tsis-cellulosic Cheebtsam, tawm hauv qab purified cellulose fibers.
3. Enzymatic Hydrolysis: Enzymatic hydrolysis siv enzymes los rhuav tshem cellulose rau hauv cov suab thaj soluble, uas tuaj yeem fermented rau hauv biofuels lossis lwm yam biochemicals.

Cov khoom ntawm Cellulose Fiber:

1. Lub zog: Cellulose fibers paub txog lawv lub zog tensile siab, txhav, thiab ua haujlwm ntev, ua rau lawv tsim nyog rau kev siv hauv ntau yam lag luam.
2. Absorbency: Cellulose fibers muaj cov khoom nqus tau zoo, tso cai rau lawv nqus thiab khaws cov dej noo, kua, thiab tsw. Qhov no ua rau lawv zoo tagnrho rau kev siv cov khoom siv nqus, xws li cov ntaub so ntswg, cov ntaub so ntswg, thiab cov khoom siv tu cev.
3. Biodegradability: Cellulose fiber yog biodegradable thiab ib puag ncig tus phooj ywg, vim nws tuaj yeem tawg los ntawm cov kab mob mus rau hauv cov khoom tsis zoo, xws li dej, carbon dioxide, thiab cov organic teeb meem.
4. Thermal rwb thaiv tsev: Cellulose fibers muaj cov khoom siv thermal insulating, ua rau lawv tsim nyog siv rau hauv cov khoom siv rwb thaiv tsev, xws li cellulose rwb thaiv tsev, uas pab txhim kho lub zog efficiency thiab txo cov cua sov thiab cua txias.
5. Tshuaj Reactivity: Cellulose fibers tuaj yeem hloov kho tshuaj los qhia cov pab pawg ua haujlwm lossis hloov lawv cov khoom rau cov kev siv tshwj xeeb, xws li cellulose ethers, esters, thiab derivatives siv hauv tshuaj, khoom noj khoom haus additives, thiab cov ntawv thov kev lag luam.

Daim ntawv thov ntawm Cellulose Fiber:

1. Daim ntawv thiab ntim: Cellulose fiber yog cov khoom siv raw rau papermaking, siv los tsim ntau yam ntawv thiab cov khoom lag luam, nrog rau cov ntawv luam ntawv, cov ntaub ntawv ntim, cov ntaub so ntswg, thiab corrugated board.
2. Textiles thiab Apparel: Cellulose fibers, xws li paj rwb, linen, thiab rayon (viscose), yog siv nyob rau hauv textile manufacturing los tsim fabrics, yarns, thiab khaub ncaws yam khoom, nrog rau cov tsho, dresses, ris, ris, thiab phuam.
3. Cov ntaub ntawv siv: Cellulose fiber yog siv los tsim cov khoom siv ntoo, xws li particleboard, fiberboard, oriented strand board (OSB), thiab plywood, nrog rau cov ntaub ntawv rwb thaiv tsev thiab cov khoom ua vaj tse.
4. Biofuels thiab Zog: Cellulose fiber ua cov khoom noj rau biofuel ntau lawm, suav nrog ethanol, biodiesel, thiab biomass pellets, nrog rau hauv cogeneration nroj tsuag rau cua sov thiab hluav taws xob tsim.
5. Khoom noj khoom haus thiab Pharmaceuticals: Cellulose derivatives, xws li methylcellulose, carboxymethylcellulose (CMC), thiab microcrystalline cellulose (MCC), yog siv los ua thickeners, stabilizers, binders, thiab muab tso rau hauv cov khoom noj khoom haus, tshuaj, tshuaj pleev ib ce, thiab cov khoom tu tus kheej.

Xaus:

Cellulose fiber ntau yog cov khoom siv ntau yam thiab ruaj khov nrog ntau yam kev siv thoob plaws hauv kev lag luam, suav nrog kev ua ntaub ntawv, textiles, kev tsim kho, biofuels, zaub mov, thiab tshuaj. Nws txoj kev nplua nuj, rov ua dua tshiab, thiab biodegradability ua rau nws yog qhov kev xaiv zoo rau cov tuam txhab nrhiav cov khoom siv hauv eco-phooj ywg thiab ua haujlwm siab. Raws li kev lag luam txuas ntxiv tseem ceeb rau kev ruaj khov thiab kev tswj hwm ib puag ncig, cellulose fiber ntau yuav tsum ua lub luag haujlwm tseem ceeb hauv kev hloov mus rau kev lag luam ntau dua thiab muaj txiaj ntsig zoo.
