Magaca Alaabta:kaarboonaanaysan
Qaab molecular:C31H32O7
CAS Maya:25037-45-0
Qaab dhismeedka molecular Product:
Guryaha Kiimikada:
Polycarbonatewaa amorphous, aan dhadhamin, ur lahayn, polymer thermoplastic hufan oo aan sun ahayn, waxay leedahay sifooyin farsamo, kulayl iyo koronto oo aad u fiican, gaar ahaan iska 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, 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, viscositykeedu wuxuu aad uga sarreeyaa 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 iska caabbinta kiimikaad dhexdhexaad ah, oo kiimiko ahaan u adkaysata asiidhka iyo alkolada 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.
