Guryaha Kiimikada:

Polycarbonate waa amorphous, aan dhadhamin, ur lahayn, aan sun ahayn polymer thermoplastic hufan, waxay leedahay farsamooyin heer sare ah, kuleyl iyo koronto, gaar ahaan caabbinta saameynta, adkaanta wanaagsan, gurguurta waa yar tahay, cabbirka alaabtu waa mid deggan.Awoodeeda saamaynta leh ee 44kj / mz, xoogga xajinta> 60MPa.iska caabinta kulaylka polycarbonate waa wanaagsan tahay, waxaa loo isticmaali karaa waqti dheer at - 60 ~ 120 ℃, heerkulka leexashada 130 ~ 140 ℃, heerkulka kala guurka galaas of 145 ~ 150 ℃, ma dhibic dhalaalid cad, in 220 ~ 230 ℃ waa dhalaalay gobolka .Heerkulka burburka kulaylka> 310 ℃.Sababtoo ah qallafsanaanta silsiladda molecular, viscosity dhalaalkiisu aad ayuu uga sarreeyaa tan heerkulbeegga guud.

Codsiga:

Polycarbonates waa balaastiig aad looga isticmaalo warshadaha casriga ah oo leh heerkul wanaagsan iyo iska caabin saameyn leh.Balaastigani waxa uu si gaar ah u fiican yahay in lagu shaqeeyo farsamooyin qeexitaan oo caadi ah (ku-durid qaabaynta, tuubooyinka ama dhululubada iyo heerkulbeegga).Waxa kale oo la isticmaalaa marka daah-furnaanta indhaha loo baahan yahay, iyadoo in ka badan 80% gudbinta ilaa 1560-nm kala duwan (kala duwan infrared mawjada gaaban).Waxay leedahay sifooyin caabbinta kiimikaad dhexdhexaad ah, oo kiimiko ahaan u adkaysata asiidhka iyo aalkolada la milmay.Waxay si liidata uga hortagtaa ketones, halogens, iyo asiidhyada uruursan.Khasaaraha ugu weyn ee la xidhiidha polycarbonates waa heerkulka kala-guurka dhalada hooseeya (Tg> 40 ° C), laakiin weli waxaa inta badan loo isticmaalaa sida walxo jaban ee nidaamyada microfluidic iyo sidoo kale lakabka allabari.
