Raws li qhov muaj koob meej ntawm lub zog tshiab lub tsheb lag luam tseem nce ntxiv, lub nkoj caij nkoj kuj tau txais kev saib xyuas los ntawm cov saw hlau kev lag luam.Nrog rau kev txhim kho txuas ntxiv ntawm roj teeb thev naus laus zis, kev tsim lub teeb pom kev zoo uas tuaj yeem txo qhov siab ntawm cov qauv tsim tau maj mam dhau los ua cov ntawv tseem ceeb rau cov tsheb tshiab.Lub koom haum ntawm Automotive Engineers ntawm Tuam Tshoj tau hais hauv "Technical Roadmap 2.0 for Energy Saving and New Energy Vehicles" tias nws xav tias los ntawm 2035, lub teeb yuag coefficient ntawm cov neeg caij tsheb hluav taws xob ntshiab yuav raug txo los ntawm 35%.
Tam sim no, cov thev naus laus zis hauv qab no tau tshwm sim hauv lub teeb yuag ntawm cov khoom siv tsheb tsis yog hlau: micro-foaming yuag txo technology, nyias-walled yuag txo technology, tsawg-density yuag txo cov khoom siv technology, carbon fiber reinforced khoom technology, biodegradable khoom technology. , lwm.
Cia peb tsom mus rau yuav ua li cas cov yas tuaj yeem txo qhov hnyav ntawm lub tsheb nyob rau hauv cov nqe lus ntawm micro-foam txhaj molding tshuab?
Microfoam Txhaj Molding yog dab tsi?
Micro-foaming txhaj tshuaj moulding hloov lub siab ntawm lub tshuab txhaj tshuaj molding los ntawm kev nthuav dav ntawm tes, tsis tas yuav tsum tau ua kom lub siab ntau dhau, thiab tuaj yeem ua rau lub siab faib ua ke los ntawm cov qauv ntawm tes ntawm cov txheej txheem nruab nrab kom txo cov khoom ntom ntom ntawm cov khoom thiab ua tiav. controllable foaming tus nqi Los txo qhov hnyav ntawm cov khoom, cov kab noj hniav siab yog txo los ntawm 30% -80%, thiab cov kev ntxhov siab sab hauv yuav txo tau zoo heev.
Cov txheej txheem ntawm micro-foaming txhaj tshuaj molding txheej txheem yog qhov yooj yim.Ua ntej, nws yog ib qho tsim nyog los yaj cov kua dej supercritical rau hauv cov khoom tseem ceeb ntawm cov yas, thiab tom qab ntawd txau cov khoom sib xyaw ua ke rau hauv pwm los ntawm cov cuab yeej siv tshuaj tua hluav taws xob los tsim micro-foaming.Tom qab ntawd, raws li qhov siab thiab qhov kub thiab txias hauv pwm tau ruaj khov, cov microbubbles hauv pwm yog nyob rau hauv lub xeev ruaj khov.Nyob rau hauv txoj kev no, cov txheej txheem txhaj tshuaj molding yog ua tiav.
