Raws li lub ntuj polymer sib xyaw, cellulose muaj ntau cov kev siv hauv kev tsim khoom. Nws yog feem ntau yog los ntawm cov phab ntsa ntawm tes ntawm cov nroj tsuag thiab yog ib qho ntawm cov organic ntau tshaj plaws hauv ntiaj teb. Cellulose tau siv dav hauv cov ntawv tsim, cov kws tsim khoom, tshuaj, ib puag ncig cov qauv molecular, ib puag ncig zoo nkauj thiab cov tshuaj zoo thiab tshuaj lom neeg.
1. Papermaking Kev Lag Luam
Lub papermaking kev lag luam yog lub ntsiab ntawv thov teb ntawm cellulose. Cog cov fibers tuaj yeem tsim mus rau hauv cov nqaij mos yog siv tshuaj lom neeg. Cellulose muaj lub zog thiab lub siab raws li lub ntsiab tiv thaiv hauv cov txheej txheem no. Hauv cov txheej txheem papermakakaking, kev nqus dej, du thiab tensile lub zog ntawm daim ntawv tuaj yeem tswj tau los ntawm kev ntxiv cov tshuaj ntxiv rau tshuaj ntxiv thiab siv cov compress sib xyaw sib txawv. Qhov tshwm sim ntawm cov ntawv rov qab ua ntxiv hais tias muaj kev txhawb nqa kom ruaj khov thiab rov ua dua tshiab ntawm cov ntaub ntawv zoo ib puag ncig.
2. Textile kev lag luam
Cellulose fibers (xws li paj rwb) tau siv dav hauv kev tsim cov khoom siv ntawm cov ntaub ntawv ntawm cov khoom lag luam textile. Paj rwb fibers muaj ntau dua 90% cellulose, uas ua rau lawv muag muag, ua pa, haum rau kev tsim cov khaub ncaws ntau yam khaub ncaws. Nyob rau hauv xyoo tsis ntev los no, cellulose fibers tuaj yeem kho tau los tsim cov cellulose cellulose thiab modal fibulose, txuas ntxiv ntawm kev lag luam cellulose hauv cov textile kev lag luam. Cov fibers tsis yog tsuas yog mos thiab xis, tab sis kuj muaj cov tshuaj tua kab mob zoo thiab cov khoom lag luam zoo.
3. Bioplastics thiab biodegradable cov ntaub ntawv
Cellulose tuaj yeem siv los ua biodegradable plastics nyob rau hauv lub plastics kev lag luam, uas yog ib qho ntawm cov kev tshawb fawb tseem ceeb rau kev daws teeb meem "dawb paug". Los ntawm kev ua lag luam cellulose acetate lossis cellulose ether, nws tuaj yeem siv los ua Eco cov khoom siv hluav taws xob ruaj khov thiab lwm yam, thiab yog ib qho yooj yim rau hauv lub ntuj ib puag ncig, txo qhov cuam tshuam ntawm cov khib nyiab yas ntawm ecological ib puag ncig.
4. Lub tsev cov ntaub ntawv
Hauv kev tsim kho kev tsim kho, cellulose yog dav siv los ua fiber ntau cam cia siab txhawb gypsum laug cam thiab thermal rwb thaiv tsev cov ntaub ntawv. Kev sib txuas ua ke nrog cov ntaub ntawv cellulose nrog lwm cov ntaub ntawv tuaj yeem txhim kho lawv cov kev cuam tshuam, lub zog ua kom muaj zog, thiab txhim kho cov cua sov rwb thaiv tsev thiab rwb thaiv tsev lub suab. Piv txwv li, cellulose thermal rwb thaiv tsev cov khoom yog ib puag ncig tus phooj ywg rhaub hluav taws xob cov khoom siv. Los ntawm txhaj cov cellulose hmoov los yog cellulose tso rau hauv lub phab ntsa, nws tuaj yeem insulate thiab txo suab nrov, thiab nws cov nus muag cov khoom ua rau nws siv dav dav siv hauv kev tsim kho.
5. Khoom noj khoom haus thiab kev lag luam kws tshuaj
Cellulose derivatives xws li carboxymethyl cellulose (cmc) thiab methyl cellulose (MC) kuj muaj cov ntawv thov tseem ceeb hauv cov zaub mov thiab tshuaj lag luam. Carboxymethyl cellulose tau siv dav siv raws li cov tuab, stabilizer thiab emulsyl feem ntau siv los ua tus tsis sib haum xeeb thiab biocompatibility. Ib qho ntxiv, cellulose kuj tseem tuaj yeem muab ntxiv rau cov zaub mov ua noj fiber ntau los pab tib neeg txhim kho kev noj qab haus huv.
6. Cov tshuaj pleev ib ce kev lag luam
Cellulose feem ntau siv los ua tuab thiab stabilizer hauv tshuaj pleev ib ce. Piv txwv li, nquag carboxymethyl cellulose thiab microcrystalline cellulose tuaj yeem nce cov tshuaj viscosity thiab kev ruaj ntseg ntawm cov tshuaj pleev ib ce thiab tsis txhob stratification ntawm cov khoom xyaw. Tsis tas li ntawd, qhov tsis txaus ntseeg thiab tsis muaj tshuaj lom ntawm cellulose ua nws haum rau siv nyob rau hauv cov khoom siv ntxuav, cov khoom tu tawv nqaij thiab pleev.
7. Ib puag ncig cov ntaub ntawv phooj ywg thiab cov khoom lim
Vim yog cov qauv ntxig thiab adsorption zoo ntawm cellulose, nws yog nce siv hauv cov khoom lim. Cellulose membranes thiab cellulose nanofibers tau siv nyob rau hauv cov pa hluav taws xob, kev kho cov dej thiab kev lag luam pov tseg. COLULOSE lim cov ntaub ntawv tsis tuaj yeem tsuas yog tshem tawm cov lus raug tshem tawm, tab sis kuj tau Adsorb cov teeb meem phom sij, nrog kev tiv thaiv zoo thiab kev tiv thaiv ib puag ncig. Ib qho ntxiv, daim ntawv thov kev tshawb fawb ntawm cellulose nanofibers ua rau nws muaj peev xwm muaj peev xwm zoo hauv kev lag luam yav tom ntej thiab kev tiv thaiv ib puag ncig thiab ib puag ncig kev lag luam.
8. Fiber teb
Cellulose calomass kuj tseem nyiam nyiam saib xyuas lub zog teb. Cellulose tuaj yeem tsim cov hluav taws xob txuas ntxiv no xws li bioethanol thiab biodiesel los ntawm biodegradation thiab fermentation. Piv nrog petrochemical lub zog, cov khoom sib txuas ntawm biomass zog yog tus phooj ywg ib puag ncig thiab hauv txoj kab nrog lub tswv yim ntawm kev txhim kho kom ruaj khov. Kev siv tshuab ntau lawm ntawm cov cellulose biofuel yog maj txhim kho, muab kev txhim kho tshiab rau cov zog huv yav tom ntej.
9. Daim ntawv thov ntawm Nanotechnology
Cellulose Nanofibers (CNF) yog qhov tseem ceeb hauv kev tshawb fawb cellulose nyob rau hauv xyoo tas los no. Vim lawv lub zog siab, qhov ntom ntom ntom thiab zoo biocompatibility, lawv tau siv dav hauv ntau yam khoom siv sib xyaw. Qhov kev sib ntxiv ntawm cellulose nanofibers tuaj yeem txhim kho cov cuab yeej siv hluav taws xob, yog li lawv muaj cov khoom siv hluav taws xob, yog li lawv muaj cov kws kho mob, kev cog lus kev kho mob, cov ntaub ntawv kev kho mob thiab cov ntaub ntawv kev ua haujlwm siab.
10. Luam tawm thiab Inkjet Technology
Hauv kev luam ntawv thiab cov inkjet thev naus laus zis, cellulose derivatives yog siv los txhim kho cov inks thiab adsorption ntawm inks, ua cov luam ntawv nyiav kev sib txawv. Nyob rau hauv inkjet Printing inks, cellulose tuaj yeem ua cov xim ntau thiab meej. Tsis tas li ntawd, cov pob tshab thiab lub zog ntawm cellulose tuaj yeem txhim kho cov ntawv luam tawm zoo thiab yog li ua cov luam tawm cov khoom lag luam zoo dua.
Raws li hloov kho tshiab thiab cov tsis muaj txiaj ntsig zoo nkauj polymer, cellulose tau dhau los ua ib qho ntawm cov ntaub ntawv tseem ceeb hauv kev tsim khoom niaj hnub no. Nws cov ntawv thov thoob plaws hauv cov sib txawv qhia txog kev tiv thaiv ntau haiv neeg thiab ib puag ncig kev tiv thaiv, thiab txhawb nqa cov kev hloov pauv ntsuab ntawm ntau kev lag luam. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho kev tshawb fawb txuas ntxiv thiab thev naus laus zis thiab kev sib tawg ntawm cellulose, daim ntawv thov ntawm cellulose yuav muaj ntau yam sib txawv.
