Igama Lomkhiqizo:i-polycarbonated

Ifomethi ye-Molecular:I-C31H32O7

Inombolo ye-CAS:25037-45-0

Isakhiwo samangqamuzana omkhiqizo:

Chemical Properties:

I-Polycarbonateiyi-amorphous, ayinambitheki, ayinaphunga, ingenabuthi i-thermoplastic polymer esobala, inezindawo ezinhle kakhulu zomshini, ezishisayo nezikagesi, ikakhulukazi ukumelana nomthelela, ukuqina okuhle, ukukhasa kuncane, usayizi womkhiqizo uzinzile. Amandla ayo womthelela we-notched angu-44kj/mz, amandla e-tensile> 60MPa. Ukumelana nokushisa kwe-polycarbonate kuhle, kungasetshenziswa isikhathi eside ku- - 60 ~ 120 ℃, izinga lokushisa lokuchezuka kokushisa 130 ~ 140 ℃, izinga lokushisa lokushintsha kwengilazi lingu-145 ~ 150 ℃, alikho iphuzu elincibilikayo elisobala, ngo-220 ~ 230 ℃ liyisimo esincibilikisiwe. . Izinga lokushisa lokubola okushisayo> 310 ℃. Ngenxa yokuqina kweketango lamangqamuzana, i-viscosity yayo yokuncibilika iphakeme kakhulu kunaleyo ye-thermoplastics evamile.

Isicelo:

Ama-Polycarbonates amapulasitiki asetshenziswa kakhulu embonini yesimanje anokushisa okuhle kanye nokumelana nomthelela. Le pulasitiki inhle kakhulu ukusebenza ngezindlela ezijwayelekile zokuchaza (ukubumba umjovo, ukukhishwa kumashubhu noma amasilinda kanye ne-thermoforming). Ibuye isetshenziswe lapho ukukhanya kwe-optical kudingekile, ibe nokudluliswa okungaphezulu kuka-80% kuze kufike kububanzi be-1560-nm (ibanga elifushane le-infrared wave). Inezindawo zokumelana namakhemikhali ezilinganiselwe, ukumelana ngamakhemikhali nama-asidi ahlanjululwe kanye notshwala. Ayizweli kahle kuma-ketone, ama-halogen, nama-acid agxilile. Ububi obukhulu obuhlobene nama-polycarbonates izinga lokushisa eliphansi lengilazi elishintshayo (Tg> 40°C), kodwa lisasetshenziswa kakhulu njengento ebiza kancane ezinhlelweni ezincane ze-microfluidic kanye nanjengosendlalelo somhlatshelo.
