Cov ntaub ntawv dav dav rau Polycarbonate
Polycarbonate yog cov khoom siv ruaj khov. Txawm hais tias nws muaj kev cuam tshuam-ua haujlwm, nws muaj kev khawb-ua haujlwm tsawg.
Yog li ntawd, ib qho nyuaj txheej yog siv rau polycarbonate eyewear lo ntsiab muag thiab polycarbonate sab nrauv automotive Cheebtsam. Cov yam ntxwv ntawm polycarbonate piv rau cov polymethyl methacrylate (PMMA, acrylic), tab sis polycarbonate muaj zog dua thiab yuav tuav ntev dua rau qhov kub thiab txias. Thermally processed material feem ntau yog tag nrho amorphous, thiab vim li ntawd nws yog pob tshab heev rau pom lub teeb, nrog lub teeb kis tau zoo dua li ntau hom iav.
Polycarbonate muaj lub iav hloov pauv kub txog li 147 ° C (297 ° F), yog li nws softens maj mam saum toj no thiab ntws saum toj no li 155 ° C (311 ° F). Cov cuab yeej yuav tsum tau tuav ntawm qhov kub thiab txias, feem ntau siab tshaj 80 ° C. (176 ° F) ua kom cov khoom tsis muaj zog thiab tsis muaj kev ntxhov siab. Cov qib molecular pawg tsawg yog yooj yim rau pwm dua cov qib siab dua, tab sis lawv lub zog qis dua vim qhov tshwm sim. Cov qib toughest muaj qhov siab tshaj plaws molecular mass, tab sis nyuaj dua rau kev ua haujlwm.
