West Sichuan, Nyiv, Lub Cuaj Hli 27, 2018 / PRNewswire / -Nanocellulose tau hais tias yog tiam tom ntej ntawm cov ntaub ntawv zoo ib puag ncig.Nws yog muab los ntawm tej yam ntuj tso biomass xws li ntoo, nroj tsuag thiab pov tseg ntoo.Yog li ntawd, nanocellulose yog recyclable thiab biodegradable.Vim tias nws cov khoom siv raw yog cov khoom siv ntuj tsim, nws tuaj yeem tau txais ntawm tus nqi qis.Yog li ntawd, nanocellulose yog ib qho zoo heev ntsuab, tiam tom ntej nanomaterial.Qhov sib piv siab ntawm nanocellulose stems los ntawm nws qhov dav (4-20 nm) thiab ntev (ob peb microns).Nws qhov hnyav yog li ib feem tsib ntawm cov hlau, tab sis nws lub zog yog ntau tshaj tsib npaug ntawm cov hlau.Nanocellulose muaj cov thermal expansion coefficient tsawg, uas yog piv rau iav fiber ntau, tab sis nws cov elastic modulus siab dua li cov iav fiber ntau, ua rau nws muaj zog, muaj zog, thiab cov khoom siv ruaj khov.Yog li ntawd, cov khoom siv sib xyaw ntawm nanocellulose thiab yas yuav tsum txhim kho lub zog ntawm cov yas thiab txo qhov hnyav.Tsis tas li ntawd, vim nws tsis tshua muaj thermal expansion coefficient, deformation yog suppressed thaum lub sij hawm yas molding.Tsis tas li ntawd, kev sib xyaw nanocellulose tuaj yeem ua rau cov yas biodegradable rau qee yam.Yog li ntawd, nanocellulose tuaj yeem dhau los ua cov khoom siv tshiab zoo heev rau tsheb, aerospace, kev tsim kho thiab lwm yam kev siv, thaum muaj kev cuam tshuam ib puag ncig zoo.Txawm li cas los xij, vim tias qhov hydrophilic ntawm nanocellulose (feem ntau cov yas yog hydrophobic), cov kws tshawb fawb tau ntsib teeb meem hauv kev tsim cov nanocellulose thiab cov yas sib xyaw.
Nyob rau hauv no hais txog, lub Green Science Alliance Co., Ltd. (cov pab pawg tuam txhab ntawm Fuji Pigment Co., Ltd.) kom deb li deb tau ntse tsim ib tug txheej txheem tsim rau tov nano-cellulose nrog ntau yam thermoplastics, uas yog polyethylene (PE), polypropylene (PP), thiab polychloride.Ethylene (PVC), polystyrene (PS), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polymethyl methacrylate (PMMA), polyamide 6 (PA6), polyvinyl cawv Butyral (PVB).Tsis tas li ntawd, tsis ntev los no, Green Technology Alliance Co., Ltd. tau ua tiav cov txheej txheem tsim khoom rau kev sib xyaw nano-cellulose nrog ntau hom biodegradable plastics.Lawv yog polylactic acid (PLA), polybutylene adipate terephthalate (PBAT), polybutylene succinate (PBS), polycaprolactone, starch-based plastics thiab cov khoom tsim los ntawm cov kab mob.Cov yas degradable, xws li polyhydroxyalkanoate (PHA).Tshwj xeeb tshaj yog cov composite ntawm nano cellulose thiab biodegradable yas, txhim kho txhua yam muaj zog thiab txhim kho cov yas kev ua tau zoo muaj qhov tseem ceeb scientific, vim nano cellulose kuj biodegradable.Kev siv cov ntaub ntawv xws li av nplaum, iav fiber ntau, thiab carbon fiber ntau tuaj yeem ua rau cov neeg kho tshuab muaj zog, tab sis lawv tsis yog biodegradable.Cov khoom siv tshiab no tuaj yeem ua rau kev siv cov yas biodegradable.Yog li no, cov khoom siv biodegradable yas / nanocellulose composite tuaj yeem dhau los ua ib qho kev daws teeb meem tshiab rau cov teeb meem yas nrog rau cov pa phem hauv marine microplastic.Txawm li cas los xij, nws yuav tsum raug sau tseg tias cov ntaub ntawv tshiab no tsis lav tias lawv yuav decompose rau hauv dej thiab carbon dioxide.Lawv yog 100% biodegradable nyob rau hauv cov xwm.Lawv yuav tsum tau ua ntau yam kev ntsuam xyuas biodegradability nyob rau hauv compost, tsev neeg, dej thiab marine ib puag ncig tej yam kev mob.Green Science Alliance Co., Ltd. tab tom txiav txim siab tau txais daim ntawv pov thawj biodegradability los ntawm cov chaw tso cai hauv Tebchaws Europe, Tebchaws Meskas thiab Nyij Pooj yav tom ntej.
Green Science Alliance Co., Ltd. tau pib tsim thiab muag biodegradable yas / nanocellulose composite masterbatch cov ntaub ntawv.Tsis tas li ntawd, nyob rau yav tom ntej, lawv yuav tawm tsam kev siv cov khoom siv biodegradable yas / nanocellulose los tsim cov tais zaub mov, lub thawv zaub mov, straws, khob, khob hau thiab lwm yam khoom yas molded.Tsis tas li ntawd, lawv yuav tawm tsam daim ntawv thov ntawm supercritical foaming thev naus laus zis los siv cov khoom siv biodegradable yas / nanocellulose los ua cov khoom pwm los ua cov khoom yas pwm biodegradable sib dua thiab muaj zog.
