Mankhwala maselo kapangidwe:

Chemical Properties:

Polycarbonatendi amorphous, zoipa, odorless, sanali poizoni mandala thermoplastic polima, ali kwambiri mawotchi, matenthedwe ndi magetsi katundu, makamaka zimakhudza kukana, zabwino toughness, zokwawa zazing'ono, mankhwala kukula ndi khola. Mphamvu zake zosawerengeka za 44kj / mz, kulimba kwamphamvu> 60MPa. polycarbonate kutentha kukana ndi zabwino, angagwiritsidwe ntchito kwa nthawi yaitali pa - 60 ~ 120 ℃, kutentha kupatukana kutentha 130 ~ 140 ℃, galasi kusintha kutentha 145 ~ 150 ℃, palibe zoonekeratu kusungunuka, mu 220 ~ 230 ℃ ndi wosungunuka boma . Kutentha kwa kutentha kwa kutentha > 310 ℃. Chifukwa cha kulimba kwa unyolo wa ma molekyulu, kukhuthala kwake kumasungunuka ndikwambiri kuposa thermoplastics wamba.

Ntchito:

Ma polycarbonates ndi mapulasitiki omwe amagwiritsidwa ntchito kwambiri m'makampani amakono okhala ndi kutentha kwabwino komanso kukana mphamvu. Pulasitiki iyi ndiyabwino kwambiri kuti igwire ntchito ndi njira zamatanthauzidwe wamba (kuumba jekeseni, kutulutsa machubu kapena masilindala ndi thermoforming). Amagwiritsidwanso ntchito pamene kuwala kwa kuwala kukufunika, kukhala ndi kupitirira 80% kufalitsa mpaka 1560-nm range (short wave infrared range). Lili ndi mphamvu zolimbana ndi mankhwala, zomwe zimagonjetsedwa ndi ma asidi osungunuka ndi mowa. Imalimbana bwino ndi ma ketoni, ma halogen, ndi ma acid ambiri. Choyipa chachikulu chokhudzana ndi ma polycarbonates ndi kutentha kwa magalasi otsika (Tg> 40 ° C), koma amagwiritsidwabe ntchito ngati zinthu zotsika mtengo m'makina a microfluidic komanso ngati gawo loperekera nsembe.
