Polycarbonate (PC ipfupi, zita rayo rinobva muboka rayo remukati CO3. ) ipolymer ine mapoka ecarbonate mucheni yemamorekuru, inogona kupatsanurwa kuita aliphatic, inonhuhwirira, uye aliphatic-inonhuhwirira mhando maererano nechimiro cheboka reester. Pakati pazvo, iyo mechanical properties yealiphatic uye aliphatic-aromatic polycarbonate yakaderera, nokudaro inoderedza kushandiswa kwayo mumapurasitiki einjiniya. Parizvino, polycarbonate inonhuhwirira chete ndiyo yakagadzirwa mumaindasitiri. Nekuda kwechimiro chepolycarbonate, yave inokurumidza kukura einjiniya plastiki pakati pemapurasitiki makuru einjiniya mashanu.
Chemical Zvivakwa
Polycarbonate inopesana neasina simba acids, mabhesi asina simba uye mafuta asina kwaakarerekera. PC inenge isina ruvara girazi amorphous polymer ine yakanaka optical zvivakwa. PC yakakwira molecular uremu resin ine kusimba kwepamusoro, cantilever beam notch inokanganisa simba re600 ~ 900J/m, tembiricha yekupisa yegiredhi isina kuzara ingangoita 130 ° C, girazi fiber yakasimbiswa inogona kuwedzera kukosha uku ne10 ° C. Kubhenda modulus yePC inogona kusvika 2400 MPa kana kupfuura, iyo resin inogona kugadziriswa kuita hombe dzakaomarara zvigadzirwa.
Proper Properties
Polycarbonate: Density: 1.18-1.22 g/cm^3 Linear Expansion: 3.8×10^-5 cm/°C Heat deflection Tembiricha: 135°C Low tembiricha -45°C. Polycarbonate haina ruvara uye yakajeka, isingadziviriri kupisa, inodzivirira kukanganisa, murazvo unodzoreredza BI giredhi, uye ine yakanaka mechanicha zvimiro patembiricha yakajairwa. Kuenzaniswa nekuita padhuze nepolymethyl methacrylate, polycarbonate ine yakanaka kukanganisa kuramba, yakakwira refractive index, yakanaka kugadzirisa mashandiro, uye UL94 V-0 level flame retardant performance isina additives.
Zvakanakira

1. High simba uye elasticity, yakakwirira simba simba, yakakura tembiricha siyana;
2. Kujeka kwepamusoro uye kusununguka kwemavara;
3. Low shrinkage rate uye yakanaka dimensional kugadzikana.
4. Kuramba kuneta kwakanaka;
5. Kuramba kwakanaka kwemamiriro ekunze;
6. Yakanakisa maitiro emagetsi.
