Hais txog cellulose
Cellulose yog macromolecular polysaccharide tsim los ntawm cov piam thaj. Nws muaj nyob rau hauv cov khoom loj hauv cov nroj tsuag ntsuab thiab cov kab mob marrine. Nws yog qhov feem ntau faib cov khoom faib loj tshaj plaws thiab cov khoom siv polymer loj tshaj plaws hauv xwm. Nws muaj zoo biocompatibility, rov txuas dua tshiab thiab biodegradable thiab lwm yam zoo. Los ntawm cov photosynthesis, nroj tsuag muaj peev xwm synthesize ntau pua lab ntawm tons ntawm cellulose txhua xyoo.
Cellulose Thov Prospects
Cellulose Tsaus tau txwv nws qhov kev siv lub cev thiab tshuaj lom neeg, thaum lub sij hawm ntuj polymer cov khoom siv sib txawv tom qab kev xav tau sib txawv ntawm ntau yam kev lag luam. Cov khoom siv ua haujlwm ntawm cov ntaub ntawv cellule ua haujlwm tau dhau los ua kev loj hlob ntawm kev txhim kho thiab kev tshawb fawb cov hotspots ntawm cov ntaub ntawv polymer.
Cellulose derivatives yog tsim los ntawm esterification los yog etherification ntawm cov pab pawg hydroxyl hauv cov polymers nrog tshuaj lom neeg. Raws li cov qauv tsim ntawm cov tshuaj tiv thaiv cov tshuaj tiv thaiv tuaj yeem muab faib ua peb pawg: kev pab cuam cellulose, thiab cellulose ether.
1. Cellulose ether
Cellulose ether yog ib lo lus dav dav rau cov tshuaj tiv thaiv cellulose tsim los ntawm cov tshuaj tiv thaiv ntawm alkali cellulose thiab tus sawv cev rau qee yam. Cellulose ether yog hom ntawm cellulose derivative nrog ntau hom kev thov cov khoom siv, ntim ntau thiab cov kev tshawb nrhiav siab muaj nuj nqis. Nws daim ntawv thov koom nrog ntau cov liaj teb xws li kev lag luam, kev ua liaj ua teb, kev tiv thaiv txhua hnub, kev tiv thaiv ib puag ncig, tiv thaiv kev tiv thaiv kev tiv thaiv.
Lub cellulose cov neeg hais tias qhov tau siv tiag tiag yog: metyl cellulose, cellulropyl cellulose thiab hydroxyprropylulose cellulose thiab lwm yam.
2. Cellulose Ester
Cov cellulose tau siv dav hauv kev tiv thaiv kev tiv thaiv kev tiv thaiv hauv tebchaws, tshuaj lom neeg siv tshuaj lom neeg, tshuaj, kev tsim kho thiab txawm tias aerospace.
Cov cellulose Esters uas tau ua lag luam tiag tiag siv yog: cellulose itrate, cellulose acetate, cellulose acetate Butetate Butetate Butetate Butetate Xantej thiab Cellule.
3. Cellulose ether ester
Cellulose ether esters yog ester-ether mixed derivatives.
Daim Ntawv Thov Teb:
1. Kws ua teb
Cellulose ether thiab ester derivatives tau siv nyob rau hauv cov tshuaj thickening, khaws cia, kev tso tawm, zaj duab xis, ua yeeb yaj kiab thiab lwm lub hom phiaj.
2. Txheej teb
Cov cellulose ua si lub luag haujlwm tseem ceeb hauv cov ntawv thov txheej.Cov celluloseSiv nyob rau hauv binders, hloov cov resins lossis ua ntej cov ntaub ntawv ua ntej los muab cov txheej ci nrog ntau cov khoom zoo tshaj plaws.
3. Tsib membrane Technology teb
Cellulose thiab cov ntaub ntawv derivative muaj qhov zoo ntawm cov zis loj, kev ua tau ruaj khov, thiab rov ua haujlwm. Los ntawm txheej-los ntawm txheej txheem kev sib dhos, theem inversion, electrospinning thev naus laus zis thiab lwm cov txhais tau tias, cov ntawv sau ua ke nrog kev sib cais zoo tuaj yeem npaj tau. Hauv daim teb ntawm daim nyias nyias siv cov tshuab siv.
4. Kev Siv Txoj Cai
Cellulose Cov neeg muaj kev hais ua ke muaj lub zog thim rov qab thiab yog li ntawd pab tau raws li cov khoom siv ntxiv hauv kev tsim cov khoom siv, xws li xasas-raws cov nplais nplaum nplaum.
5. Aerospace, lub zog hluav taws xob tshiab thiab cov khoom hluav taws xob siab hauv hluav taws xob
Cellulose-basal develunposeional deveroelectronic cov ntaub ntawv tuaj yeem siv hauv aerospace, cov tsheb loj tshiab thiab cov khoom hluav taws xob siab.
