Molecular hom:C31H32O7
CAS Nr:25037-45-0
Cov khoom siv molecular:
Chemical Properties:
Polycarbonateyog ib qho amorphous, tasteless, odorless, non-toxic pob tshab thermoplastic polymer, muaj cov khoom zoo heev, thermal thiab hluav taws xob, tshwj xeeb tshaj yog cuam tshuam, zoo toughness, creep me me, cov khoom loj yog ruaj khov. Nws muaj kev cuam tshuam lub zog ntawm 44kj / mz, tensile zog> 60MPa. polycarbonate kub tsis kam yog qhov zoo, tuaj yeem siv tau ntev ntawm - 60 ~ 120 ℃, kub deflection kub 130 ~ 140 ℃, iav hloov kub ntawm 145 ~ 150 ℃, tsis muaj qhov pom tseeb melting point, hauv 220 ~ 230 ℃ yog lub xeev molten . Thermal decomposition kub> 310 ℃. Vim lub rigidity ntawm cov saw hlau molecular, nws cov viscosity yaj yog ntau dua li ntawm cov thermoplastics.
Daim ntawv thov:
Peb qhov kev siv tseem ceeb ntawm PC engineering plastics yog iav sib dhos kev lag luam, kev lag luam tsheb thiab kev lag luam hluav taws xob thiab hluav taws xob, ua raws li kev lag luam machinery qhov chaw, optical discs, ntim, khoos phis tawj thiab lwm yam khoom siv hauv chaw ua haujlwm, kev kho mob thiab kev kho mob, zaj duab xis, kev lom zem thiab cov khoom siv tiv thaiv, thiab lwm yam. PC tuaj yeem siv los ua lub qhov rais thiab qhov rooj iav, PC laminate yog dav siv hauv cov tsev txhab nyiaj, cov chaw lis haujlwm, cov chaw kaw neeg thiab cov chaw pej xeem rau kev tiv thaiv qhov rais, rau dav hlau hatch npog, cov khoom siv teeb pom kev zoo, kev ruaj ntseg cov khw muag khoom thiab cov iav mos mos.
