Polycarbonate (PC luv luv, nws lub npe los ntawm nws pawg CO3 sab hauv.) yog ib qho polymer uas muaj cov pawg carbonate hauv cov saw hlau molecular, uas tuaj yeem faib ua aliphatic, aromatic, thiab aliphatic-aromatic hom raws li cov qauv ntawm pawg ester. Ntawm lawv, cov khoom siv kho tshuab ntawm aliphatic thiab aliphatic-aromatic polycarbonate yog qis, yog li txwv nws daim ntawv thov hauv cov yas engineering. Tam sim no, tsuas yog aromatic polycarbonate tau tsim tawm hauv kev lag luam. Vim yog qhov tshwj xeeb ntawm cov qauv ntawm polycarbonate, nws tau dhau los ua cov yas engineering dav dav uas loj hlob sai tshaj plaws ntawm tsib lub yas engineering loj.
Tshuaj khoom
Polycarbonate tiv taus cov kua qaub tsis muaj zog, cov hauv paus tsis muaj zog thiab cov roj tsis muaj zog. PC yog cov polymer amorphous iav uas yuav luag tsis muaj xim nrog cov khoom zoo optical. PC siab molecular hnyav resin muaj lub zog siab, cantilever beam notch impact zog ntawm 600 ~ 900J / m, qhov kub ntawm qhov kub ntawm qib tsis tiav yog li 130 ° C, iav fiber reinforced tuaj yeem ua rau tus nqi no nce ntxiv 10 ° C. Cov modulus khoov ntawm PC tuaj yeem ncav cuag 2400 MPa lossis ntau dua, cov resin tuaj yeem ua tiav rau hauv cov khoom loj.
Lub Cev Lub Cev
Polycarbonate: Qhov Ceev: 1.18-1.22 g/cm^3 Kev nthuav dav kab: 3.8 × 10^-5 cm/°C Kub deflection: 135°C Kub qis -45°C. Polycarbonate tsis muaj xim thiab pob tshab, tiv taus cua sov, tiv taus kev cuam tshuam, nplaim taws retardant BI qib, thiab muaj cov khoom siv kho tshuab zoo ntawm qhov kub thiab txias siv niaj hnub. Piv nrog rau kev ua tau zoo ze rau polymethyl methacrylate, polycarbonate muaj kev tiv taus kev cuam tshuam zoo, siab refractive index, kev ua haujlwm zoo, thiab UL94 V-0 qib nplaim taws retardant kev ua tau zoo yam tsis muaj additives.
Qhov zoo tshaj plaws

1. Muaj zog thiab elasticity, muaj zog cuam tshuam, kub ntau;
2. Muaj kev pom tseeb thiab xim dawb;
3. Tus nqi qis dua thiab kev ruaj khov zoo.
4. Kev tiv thaiv kev qaug zog zoo;
5. Kev tiv thaiv huab cua zoo;
6. Cov yam ntxwv hluav taws xob zoo heev.
