Polycarbonate (PC mwachidule, dzina lake limachokera ku gulu lake lamkati la CO3. ) ndi polima yomwe ili ndi magulu a carbonate mu unyolo wa maselo, omwe amatha kugawidwa m'magulu a aliphatic, onunkhira, ndi onunkhira molingana ndi kapangidwe ka gulu la ester. Pakati pawo, makina a aliphatic ndi aliphatic-onunkhira polycarbonate ndi otsika, motero amalepheretsa kugwiritsa ntchito mapulasitiki a engineering. Pakadali pano, polycarbonate yokhayo yonunkhira idapangidwa m'mafakitale. Chifukwa cha kapangidwe kake ka polycarbonate, yakhala pulasitiki yauinjiniya yomwe ikukula mwachangu pakati pa mapulasitiki akuluakulu asanu.
Zakudya Zamakono
Polycarbonate imagonjetsedwa ndi ma asidi ofooka, maziko ofooka ndi mafuta osalowerera. PC ndi pafupifupi yopanda mtundu magalasi amorphous polima yokhala ndi mawonekedwe abwino owoneka bwino. Utoto wa PC wolemera kwambiri wa ma molekyulu umakhala wolimba kwambiri, mphamvu ya cantilever beam notch imakhudza mphamvu ya 600 ~ 900J/m, kutentha kwapang'onopang'ono kwa kalasi yosadzazidwa ndi pafupifupi 130 ° C, ulusi wagalasi wolimbikitsidwa ukhoza kuwonjezera mtengo ndi 10 ° C. Kupinda modulus ya PC kumatha kufika 2400 MPa kapena kupitilira apo, utomoni ukhoza kusinthidwa kukhala zinthu zazikulu zolimba.
Zida zakuthupi
Polycarbonate: Kachulukidwe: 1.18-1.22 g/cm^3 Kukula kwa mzere: 3.8×10^-5 cm/°C Kutentha kwapang’onopang’ono: 135°C Kutentha kochepa -45°C. Polycarbonate ndi yopanda utoto komanso yowonekera, yosagwira kutentha, yosagwira ntchito, giredi ya BI yoletsa moto, ndipo imakhala ndi makina abwino pamatenthedwe ogwiritsidwa ntchito wamba. Poyerekeza ndi magwiridwe antchito omwe ali pafupi ndi polymethyl methacrylate, polycarbonate ili ndi kukana kwabwino, index yowoneka bwino kwambiri, magwiridwe antchito abwino, komanso magwiridwe antchito a UL94 V-0 opanda lawi lamoto popanda zowonjezera.
Ubwino waukulu

1. Mkulu mphamvu ndi elasticity, mkulu amakhudza mphamvu, lonse kutentha osiyanasiyana;
2. Kuwonekera kwakukulu ndi kukongoletsa kwaulere;
3. Low shrinkage mlingo ndi wabwino dimensional bata.
4. Good kutopa kukana;
5. Kukana kwanyengo kwabwino;
6. Makhalidwe abwino kwambiri amagetsi.
