Igama lemveliso:polycarbonated

Imo yemolekyuli:C31H32O7

Inombolo yeCAS:25037-45-0

Imveliso yesakhiwo semolekyuli:

Iipropati zeMichiza:

Polycarbonatei-amorphous, incasa, ayinavumba, i-polymer ye-thermoplastic engabonakaliyo, inomatshini obalaseleyo, i-thermal kunye neempawu zombane, ngokukodwa ukuxhathisa impembelelo, ukuqina okulungileyo, ukukhahlela kuncinci, ubungakanani bemveliso buzinzile. Amandla ayo empembelelo ye-notched ye-44kj / mz, amandla okuqina> 60MPa. i-polycarbonate ukumelana nobushushu ilungile, ingasetyenziselwa ixesha elide kwi-60 ~ 120 ℃, i-heat deflection yobushushu i-130 ~ 140 ℃, i-glass transition ye-145 ~ 150 ℃, akukho ndawo yokunyibilika icacileyo, kwi-220 ~ 230 ℃ yimeko etyhidiweyo. Iqondo lobushushu lokubola > 310 ℃. Ngenxa yokuqina kwekhonkco le-molecular, i-viscosity yayo yokunyibilika iphezulu kakhulu kune-thermoplastics jikelele.

Isicelo:

Iipolycarbonates ziiplastiki ezisetyenziswa kakhulu kushishino lwangoku ezinobushushu obulungileyo kunye nokumelana nefuthe. Le plastiki ilungile ngokukodwa ukuba isebenze kunye neendlela eziqhelekileyo zokuchaza (i-injection yokubumba, i-extrusion kwiityhubhu okanye iisilinda kunye ne-thermoforming). Iphinda isetyenziswe xa ukukhanya okubonakalayo kuyadingeka, kunokudluliselwa okungaphezulu kwe-80% ukuya kuluhlu lwe-1560-nm (uluhlu olufutshane lwe-infrared wave). Ineempawu zokumelana neekhemikhali ezimodareyithiweyo, zikwazi ukumelana neekhemikhali kwii-asidi ezixutyiweyo kunye neealkoholi. Ayixhathisi kakuhle kwi-ketones, iihalogens, kunye ne-concentrated acids. Eyona nto ingeloncedo kakhulu eyayanyaniswa neepolycarbonates liqondo lobushushu elisezantsi leglasi (Tg> 40°C), kodwa isasetyenziswa kakhulu njengempahla enexabiso eliphantsi kwiinkqubo zemicrofluidic nanjengomaleko wedini.
