Cov iav hloov pauv kub ntawm polycarbonate (PC) yog qhov siab, ntawm 149-150 degree, melting kub yog 215-225 degree, thiab molding kub tuaj yeem tswj tau ntawm 250-310 degree .
Polycarbonate (PC) yog cov khoom siv hluav taws xob ua haujlwm siab nrog kev ua haujlwm kub thiab txias. Nws cov iav hloov pauv kub yog li 149 degree mus rau 150 degree, uas txhais tau hais tias nyob rau hauv cov xwm txheej hauv qab no, cov ntaub ntawv PC tuaj yeem tswj xyuas lawv cov kev ua haujlwm ruaj khov. Thaum qhov kub siab tshaj qhov kub hloov pauv iav, polycarbonate yuav maj mam muag thiab ntws ntawm qhov kub siab tshaj li 155 degree. Lub melting kub, uas yog, qhov kub thiab txias ntawm cov ntaub ntawv PC hloov los ntawm cov khoom rau cov kua, yog 215 degree mus rau 225 degree, uas yog qhov kub thiab txias yuav tsum tau mus txog thaum ua cov khoom polycarbonate. Thaum lub sij hawm molding txheej txheem, molding kub tuaj yeem tswj tau ntawm 250 degree thiab 310 degree los xyuas kom meej tias cov polycarbonate tuaj yeem yaj tag nrho thiab sau cov pwm los ua cov khoom xav tau.
Tsis tas li ntawd, thermal stability thiab mechanical zog ntawm polycarbonate nce nrog qhov nce ntawm cov txheeb ze molecular loj, thiab cov yaj viscosity kuj nce ntau nrog qhov nce ntawm cov txheeb ze molecular loj. Qhov no txhais tau hais tias nyob rau hauv cov txheej txheem ntawm kev ua, cov txheej txheem kub thiab siab yuav tsum tau tswj kom zoo kom tau cov khoom polycarbonate nrog kev ua tau zoo. Nyob rau hauv cov txheej txheem ntawm kev txhaj tshuaj molding, qhov kev txhaj tshuaj siab feem ntau tswj ntawm 80-120MPa. Rau cov khoom uas muaj cov phab ntsa nyias, cov txheej txheem ntev, cov duab tsis yooj yim, thiab cov rooj vag me me, txhawm rau txhawm rau kov yeej qhov tsis kam ntawm cov dej ntws thiab sau cov pwm kab noj hniav hauv lub sijhawm, kev txhaj tshuaj ntau dua (120-145MPa) tuaj yeem raug xaiv kom tau txais ib tug ua tiav thiab du nto khoom.
