Nyob rau hauv ib txwm-evolving automotive sector, lub teeb yuag plastics tau dhau los ua kev ua si-hloov pauv. Los ntawm kev muab lub zog-rau-hnyav piv, tsim qauv yooj yim, thiab tus nqi siv tau zoo, cov khoom siv hnyav hnyav yog qhov tseem ceeb hauv kev hais txog kev lag luam kev xav tau rau kev siv roj, txo qis emissions, thiab sustainability. Txawm li cas los xij, thaum cov ntaub ntawv no muaj txiaj ntsig ntau, lawv kuj tuaj nrog cov kev cov nyom tshwj xeeb. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov mob tshwm sim hauv kev siv cov yas sib sib zog nqus hauv kev lag luam tsheb thiab muab cov kev daws teeb meem uas tuaj yeem txhim kho kev ua tau zoo thiab txo cov nqi tsim khoom.
Dab tsi yog Cov Khoom Siv Hluav Taws Xob?
Cov yas sib zog yog cov polymers tsawg, xws li polyethylene (PE), polypropylene (PP), polystyrene (PS), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), thiab polybutylene terephthalate (PBT), nrog qhov ceev ntawm 0.8-1.5 g / cm³. Tsis zoo li cov hlau (piv txwv li, steel: ~ 7.8 g / cm³), cov yas no txo qhov hnyav yam tsis muaj qhov tseem ceeb ntawm cov khoom siv hluav taws xob lossis thermal. Advanced xaiv xws li foamed plastics (xws li, nthuav polystyrene, EPS) thiab cov thermoplastic composites ntxiv qis dua thaum tuav cov qauv kev ncaj ncees, ua rau lawv zoo tagnrho rau kev siv tsheb.
