Polycarbonate (PC maka nkenke, aha ya sitere na otu CO3 dị n'ime ya.) bụ polymer nwere otu carbonate dị n'ime eriri molecular, nke nwere ike kewaa n'ime ụdị aliphatic, aromatic, na aliphatic-aromatic dị ka nhazi nke otu ester. N'ime ha, ihe eji arụ ọrụ nke aliphatic na aliphatic-aromatic polycarbonate dị ala, si otú a na-egbochi ngwa ya na plastik engineering. Ka ọ dị ugbu a, ọ bụ naanị polycarbonate aromatic ka emepụtara n'ụlọ ọrụ. N'ihi ọdịdị dị iche iche nke polycarbonate, ọ ghọwo plastik injinịa ngwa ngwa na-eto ngwa ngwa n'etiti nnukwu plastik injinịa ise.
Chemical Properties
Polycarbonate na-eguzogide acid na-adịghị ike, ntọala adịghị ike na mmanụ na-anọpụ iche. PC bụ ihe fọrọ nke nta ka ọ bụrụ enweghị agba amorphous polymer nwere ezigbo ngwa anya. PC elu molecular arọ resin nwere elu siri ike, cantilever beam notch mmetụta ike nke 600 ~ 900J / m, okpomọkụ deflection okpomọkụ nke na-ejuputaghị ọkwa bụ banyere 130 ° C, iko eriri mesikwuru nwere ike mụbaa a uru site 10 ° C. Ehulata modulu nke PC nwere ike iru 2400 MPa ma ọ bụ karịa, enwere ike ịhazi resin n'ime nnukwu ngwaahịa siri ike.
Njirimara ahụ
Polycarbonate: Njupụta: 1.18-1.22 g / cm ^ 3 Mgbasawanye Linear: 3.8 × 10 ^ -5 cm / ° C Okpomọkụ na-atụgharị: 135 ° C Obere okpomọkụ -45 ° C. Polycarbonate enweghị agba na nghọta, ọkụ na-eguzogide, mmetụta na-eguzogide, ọkụ retardant BI ọkwa, ma nwee ezigbo ihe eji arụ ọrụ na ọnọdụ okpomọkụ nkịtị. E jiri ya tụnyere arụmọrụ dị nso na polymethyl methacrylate, polycarbonate nwere mmetụta dị mma na-eguzogide, nnukwu refractive index, ezigbo nhazi arụmọrụ, na UL94 V-0 larịị ọkụ retardant arụmọrụ na-enweghị mgbakwunye.
