Yas, ib tug zoo invention nyob rau hauv lub xyoo pua 20th, nws cov tsos tau txhawb txoj kev loj hlob ntawm kev lag luam thiab hloov tib neeg lub neej;yas, ib tug phem invention nyob rau hauv lub xyoo pua 20th, nws cov pa phem thiab txawm qhov phem los ntawm ib puag ncig tseem tsis tau daws - qhov zoo ntawm plastics thiab qhov tsis zoo yog zoo li "ob-edged ntaj" nyob rau hauv lub neej tiag tiag, nws muaj zog txaus. , tab sis nws yog qhov txaus ntshai heev.Thiab rau peb, tus nqi qis, thermal stability, mechanical zog, processability thiab compatibility ntawm plastics ua rau nws nyuaj rau peb tsis txhob siv tag nrho cov khoom ntawm peb cov khoom, uas ua rau lub fact tias txawm peb to taub hais tias plastics yuav hem ib puag ncig. , tab sis peb tseem yuav tau tso siab rau cov khoom siv no.Nws kuj yog vim li no tias "txhais" lossis "hloov" plastics tau dhau los ua lub ntsiab lus ntev hauv kev tshawb fawb cov ntaub ntawv rau kev tiv thaiv ib puag ncig.
Qhov tseeb, cov txheej txheem no tsis yog yam tsis muaj txiaj ntsig.Tau ntev, kev tshawb fawb ntawm "hloov cov yas" tau txuas ntxiv mus, thiab ntau qhov kev ntseeg tau thiab cov txiaj ntsig tau tshwm sim ib zaug, xws li polylactic acid plastics.Thiab tsis ntev los no, ib pab neeg tshawb fawb los ntawm Lub Tsev Kawm Ntawv ntawm Kev Tshawb Fawb Kev Tshawb Fawb ntawm Swiss Tsoom Fwv Teb Chaws Technology hauv Lausanne tau tsim cov yas los ntawm biomass zoo ib yam li polyethylene terephthalate (PET).Cov khoom siv tshiab no muaj qhov zoo ntawm cov yas yas xws li muaj zog thermal stability, txhim khu kev qha txhua yam muaj zog, thiab muaj zog plasticity.Nyob rau tib lub sijhawm, cov txheej txheem ntau lawm kuj yog ib puag ncig zoo.Nws tau tshaj tawm tias cov khoom siv yas tshiab PET siv glyoxylic acid rau kev ua cov yas, uas yooj yim rau kev khiav lag luam, tab sis tuaj yeem hloov 25% ntawm cov khib nyiab ua liaj ua teb lossis 95% ntawm cov suab thaj ntshiab rau hauv cov yas.Ntxiv nrog rau kev tsim khoom yooj yim, cov khoom siv no tseem raug rau degradation vim nws cov qauv suab thaj tsis zoo.
Nws yog tsim nyog hais tias tam sim no, cov kws tshawb fawb tau ua tiav cov khoom siv no rau hauv cov khoom siv yas xws li ntim cov yeeb yaj kiab, thiab tau ua pov thawj tias nws tuaj yeem siv tau los ua 3D luam ntawv siv tau (uas yog, nws tuaj yeem ua rau hauv filaments rau 3D luam ntawv. ), yog li peb muaj laj thawj los cia siab tias cov khoom siv no yuav muaj kev thov dav dua yav tom ntej.
Xaus: Kev txhim kho cov ntaub ntawv yas yog txheej txheem los daws cov kuab paug yas los ntawm qhov chaw tiv thaiv ib puag ncig.Txawm li cas los xij, los ntawm kev xav ntawm tib neeg, qhov tseeb, qhov cuam tshuam ntawm qhov kev txhim kho no rau peb yog ntau dua uas cov cuab yeej siv hauv lub neej pib hloov.Hauv qhov sib piv, pib ntawm peb lub neej, yog tias peb xav daws cov pa phem ntawm cov yas los ntawm qhov chaw, tej zaum qhov tseem ceeb tshaj, zam kev tsim txom thiab tso tseg cov yas, ntxiv dag zog rau kev tswj hwm kev lag luam thiab kev saib xyuas kev lag luam, thiab tiv thaiv cov pa phem los ntawm kev ntws mus rau qhov xwm txheej.
