Tshuaj Tshuaj Muaj Zog:

Polycarbonateyog cov amorphous, tasteless, tsis muaj ntxhiab, tsis muaj tshuaj ntsuab, muaj feem cuam tshuam, muaj feem cuam tshuam me me, cov khoom lag luam loj yog ruaj khov. Nws tseem ceeb cuam tshuam lub zog ntawm 44kj / MZ, tensile lub zog> 60mpa. Polycarbonate tshav kub ua tau yog qhov zoo, tuaj yeem siv rau lub sijhawm ntev ntawm - 60 ~ 120 ℃, cua sov li cas, tsis muaj qhov tseeb pom kev zoo nkauj me me, hauv 220 ~ 230 ℃ yog molten lub xeev. Thermal decomprosition kub> 310 ℃. Vim yog lub rigidity ntawm cov molecular chart, nws melt viscosity muaj ntau dua li ntawm cov dav dav thermoplastics.

Daim Ntawv Thov:

Polycarbonates yog plastics dav siv hauv kev lag luam niaj hnub muaj qhov kub thiab txias thiab cuam tshuam tsis kam. Cov yas no tshwj xeeb tshaj yog ua haujlwm nrog ntau cov kev txhais cov ntsiab lus (kev txhaj tshuaj moulding (kev txhaj tshuaj thiab thooj kheej thiab thermoforming). Nws kuj yog siv thaum kho qhov muag transparency xav tau, muaj ntau dua 80% xa mus rau 1560-nm kev deb (luv luv nroog infrared ntau). Nws tau muaj cov khoom siv tshuaj lom neeg tiv thaiv cov khoom, muaj kev tiv thaiv kom tsis txhob muaj cov acids thiab cawv. Nws tsis zoo tiv taus cov ketones, halogens, thiab mloog cov accortrated. Qhov kev cuam tshuam loj uas cuam tshuam nrog Polycarbonates yog qhov ntsuas cua tsis muaj roj (tg
