Txoj kev loj hlob ntawm cov tshuab yas yog hloov nrog txhua hnub dhau mus.Kev tsim cov ntaub ntawv tshiab rau cov ntawv thov tshiab, kev txhim kho kev ua haujlwm ntawm cov khoom lag luam uas twb muaj lawm, thiab kev txhim kho kev ua tau zoo ntawm cov ntawv thov tshwj xeeb tuaj yeem piav qhia raws li ntau cov lus qhia tseem ceeb ntawm kev tsim cov khoom siv tshiab thiab kev siv tshiab.Tsis tas li ntawd, kev tiv thaiv ib puag ncig thiab degradability tau dhau los ua qhov tseem ceeb ntawm cov yas tshiab.
Cov ntaub ntawv tshiab yog dab tsi?
Bioplastics: Nippon Electric tau tsim tshiab bioplastics raws li cov nroj tsuag, uas nws thermal conductivity yog piv rau stainless hlau.Lub tuam txhab sib xyaw cov roj carbon fibers nrog qhov ntev ntawm ob peb millimeters thiab txoj kab uas hla ntawm 0.01 millimeters thiab cov nplaum tshwj xeeb rau hauv polylactic acid resin ua los ntawm pob kws los tsim ib hom tshiab ntawm bioplastic nrog cov thermal conductivity.Yog tias 10% carbon fiber sib xyaw ua ke, cov thermal conductivity ntawm bioplastic yog piv rau cov hlau tsis muaj steel;Thaum 30% carbon fiber ntxiv, thermal conductivity ntawm bioplastic yog ob zaug ntawm stainless hlau, thiab qhov ceev tsuas yog 1/5 ntawm stainless hlau.
Txawm li cas los xij, kev tshawb fawb thiab kev loj hlob ntawm bioplastics yog txwv rau thaj chaw ntawm bio-raws li raw cov ntaub ntawv los yog bio-monomers los yog polymers tsim los ntawm microbial fermentation.Nrog rau kev nthuav dav ntawm bio-ethanol thiab bio-diesel kev lag luam hauv xyoo tas los no, bio-ethanol thiab glycerol yog siv los ua cov khoom siv raw rau kev tsim khoom.Kev siv tshuab bioplastics tau txais kev saib xyuas ntau thiab tau ua lag luam.
Cov yas yas hloov xim xim tshiab: Lub Tsev Kawm Ntawv Qib Siab Southampton hauv tebchaws United Kingdom thiab Darmstadt lub koom haum rau cov yas hauv lub teb chaws Yelemees tau koom ua ke tsim cov yeeb yaj kiab hloov xim.Kev sib xyaw ua ke ntawm ntuj thiab khoom siv kho qhov muag pom kev, zaj duab xis yog ib txoj hauv kev tshiab ntawm kev ua cov khoom hloov xim.Cov yas hloov xim no yog cov yas opal zaj duab xis, uas yog tsim los ntawm cov yas spheres stacked nyob rau hauv peb-dimensional qhov chaw, thiab tseem muaj cov pa roj carbon nanoparticles me me nyob rau hauv nruab nrab ntawm cov yas spheres, yog li ntawd lub teeb tsis yog tsuas yog nyob rau hauv nruab nrab ntawm cov yas spheres thiab cov khoom nyob ib puag ncig.reflections los ntawm ntug cheeb tsam ntawm cov yas spheres, tab sis kuj los ntawm qhov chaw ntawm cov pa roj carbon nanoparticles uas sau nyob rau hauv nruab nrab ntawm cov yas spheres.Qhov no ua rau cov xim ntawm zaj duab xis tob heev.Los ntawm kev tswj cov ntim ntawm cov yas spheres, nws muaj peev xwm tsim cov khoom siv hluav taws xob uas tawg tsuas yog qee qhov spectral zaus.
Cov ntshav yas tshiab: Cov kws tshawb fawb ntawm University of Sheffield hauv tebchaws United Kingdom tau tsim cov "cov ntshav yas" uas zoo li cov kua nplaum tuab.Tsuav nws yaj hauv dej, nws tuaj yeem hloov mus rau cov neeg mob, uas tuaj yeem siv los ua ntshav hauv cov txheej txheem xwm txheej ceev.lwm txoj.Hom tshiab no cov ntshav dag yog ua los ntawm cov yas molecules.Muaj ntau lab tus yas molecules hauv ib daim ntawm cov ntshav dag.Cov molecules zoo sib xws hauv qhov loj thiab zoo li hemoglobin molecules.Lawv tuaj yeem nqa cov hlau atoms, uas thauj cov pa oxygen thoob plaws hauv lub cev zoo li hemoglobin.Txij li cov khoom siv raw yog cov yas, cov ntshav dag yog lub teeb thiab nqa tau yooj yim, tsis tas yuav tsum tau tso rau hauv tub yees, muaj lub sijhawm siv tau ntev, muaj kev ua haujlwm siab dua li cov ntshav cuav tiag tiag, thiab tsis tshua muaj nqi los tsim khoom.
Nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, cov yas tshiab txuas ntxiv mus.Cov khoom insulating, kub tsis kam thiab hluav taws kub tsis kam ntawm qee qhov high-end engineering plastics thiab cov tebchaw muaj txiaj ntsig zoo dua.Tsis tas li ntawd, kev tiv thaiv ib puag ncig thiab degradability tau dhau los ua qhov tseem ceeb ntawm cov yas tshiab.
