Tag nrho cov khoom siv hluav taws xob sib sau rau lub nra ntawm lub subway
Raws li "Daim Ntawv Qhia Txog Cov Hluav Taws Xob", lub ntiaj teb thawj zaug tag nrho cov roj carbon fiber ntau lub cev nrog cov khoom ntiag tug ntawm cov cuab yeej cuab tam yog tau tsim los ntawm China Railway Changchun Railway Vehicle Co., Ltd. (ntxiv mus rau "CRRC"). Li ntawd, yog dab tsi tag nrho cov pa roj carbon tag nrho? Dab tsi yog qhov zoo ntawm kev tsim lub subway?
Cov kua hluav taws xob tag nrho yog dab tsi? Raws li cov lus qhia los ntawm Guangming.com, carbon fiber (Lub npe lus Askiv yog Carbon Fiber) yog cov xim tshwj xeeb dub cev hauv cov phom polymer dub. Cov khoom siv khov-nos feem ntau yog tsim los ntawm carbon fiber thiab thermosetting cob thiab muaj cov yam ntxwv tsis sib xws thiab tsis txawj siv.
Muab piv rau cov ntaub ntawv sau tseg, cov kev zoo ntawm cov tsev hauv tsev nrog cov khoom siv roj carbon tagnrho zoo li cas? Raws li Xinhuanet, kev siv tagnrho fiber ntau cov ntaub ntawv yuav tsim los nrog cov yam ntxwv muaj zog thiab muaj peev xwm ua tau ib qho molded. Los ntawm kev siv ib qho moulding, lub cev muaj peev xwm tshaj Qhov kev sib tos ntawm cov cheebtsam raug ras txog, thiab qhov sib txawv ntawm qhov sib txawv thiab daim qauv-txoj haujlwm ntawm lub voj deformation ntawm cov qauv hlau raug zam, thiab qhov zoo ntawm lub cev thiab qhov zoo ntawm lub cev zoo tuaj .
Tsis tas li ntawd, cov kws tshaj lij ntawm CRRC Chevron tau hais nyob rau hauv kev xam phaj nrog Xinhua.com tias tag nrho cov pa roj carbon fiber ntau tau muaj lub teeb, lub zog-txuag, thiab lub neej ntev, thiab txais cov thev-walled txheem tag nrho cov qauv ntawm cov kabmob. Lub cev ntawm lub metro nyhav ntawm lub metro yog li 35%, uas tuaj yeem ua rau kom muaj peev xwm nce, txo kev siv zog thiab siv cov nqi, thiab txo qhov kev hnav lub thawv hauv subway.
Ntxiv rau lub tsev tsheb, cov khoom siv hluav taws xob thoob khib nyiab tseem siv nyob rau hauv Suav teb tus thawj hluav taws xob kev sib tw ua si, lub Ruixiang 2-seev fais fab aircraft. Raws li "Science thiab Technology Daily" qhia, qhov kev sib tw ua si sib ntaus sib tua no tau txais ib qho khoom siv tagnrho txhua tus qauv thiab yog ib thaj chaw zoo, tsis-polluting, muaj kev nyab xeeb thiab yoojyim, yooj yim rau kev khiav lag luam, thiab muaj kev khiav haujlwm tsawg. Kev vam meej ntawm txoj kev dav hlau no tau tshaj tawm tias Tuam Tshoj lub teeb hluav taws xob Lub tshav pob ntawm aircraft tau mus txog thoob ntiaj teb qib siab.
Nws ntseeg hais tias nrog kev nruam dhau ntawm kev tshawb fawb thiab kev siv tshuab, tagnrho cov ntaub ntawv roj carbon fiber ntau yuav muaj ntau daim ntawv sau nyob rau ntau thaj chaw.
