Polycarbonate (PC a takaice, sunansa ya fito ne daga rukunin CO3 na ciki.) polymer ne wanda ke dauke da kungiyoyin carbonate a cikin sarkar kwayoyin halitta, wanda za'a iya raba shi zuwa nau'in aliphatic, aromatic, da aliphatic-aromatic iri bisa ga tsarin ƙungiyar ester. Daga cikin su, kayan aikin injiniya na aliphatic da aliphatic-aromatic polycarbonate suna da ƙananan, don haka yana iyakance aikace-aikacensa a cikin robobi na injiniya. A halin yanzu, kawai polycarbonate aromatic an samar da masana'antu. Saboda ginshiƙan tsarin polycarbonate, ya zama filastik injin injiniya mafi girma cikin sauri a cikin manyan robobin injiniya guda biyar.
Chemical Properties
Polycarbonate yana da tsayayya ga raunin acid, raunin tushe da mai tsaka tsaki. PC shine polymer amorphous gilashi kusan mara launi tare da kyawawan kaddarorin gani. PC high kwayoyin nauyi guduro yana da high tauri, cantilever katako daraja tasiri ƙarfin 600 ~ 900J / m, zafi deflection zafin jiki na unfilled sa ne game da 130 ° C, gilashin fiber ƙarfafa iya ƙara wannan darajar da 10 ° C. Lankwasawa modules na PC iya isa 2400 MPa ko fiye, da guduro za a iya sarrafa a cikin manyan m kayayyakin.
jiki Properties
Polycarbonate: Yawanci: 1.18-1.22 g/cm ^ 3 Fadada layin layi: 3.8 × 10 ^ - 5 cm / ° C Zafin karkatar da zafi: 135 ° C Ƙananan zafin jiki -45 ° C. Polycarbonate ba shi da launi kuma mai haske, juriya mai zafi, juriya mai tasiri, ƙarancin wuta, kuma yana da kyawawan kaddarorin injina a yanayin yanayin amfani na yau da kullun. Idan aka kwatanta da aikin da ke kusa da polymethyl methacrylate, polycarbonate yana da tasiri mai kyau juriya, babban ma'anar refractive, kyakkyawan aikin aiki, da UL94 V-0 matakin harshen wuta ba tare da ƙari ba.
Babban amfani

1. Ƙarfin ƙarfi da haɓaka, ƙarfin tasiri mai ƙarfi, kewayon zafin jiki mai yawa;
2. Babban nuna gaskiya da canza launin kyauta;
3. Ƙananan raguwa da kwanciyar hankali mai kyau.
4. Kyakkyawan juriya ga gajiya;
5. Kyakkyawan juriya na yanayi;
6. Kyakkyawan halayen lantarki.
