Hōputu rāpoi:C31H32O7

No CAS:25037-45-0

Hanganga ngota hua：

Ngā Āhuatanga matū:

Polycarbonatehe waikura hauhaumaru, he kore reka, he kakara, he paitini kore-paitini, he tino pai te miihini, te waiariki me te hiko, ina koa te atete paanga, te pakari pai, he iti te ngokingoki, he pumau te rahi o te hua.Ko te kaha o te paahitanga o te 44kj / mz, te kaha tensile > 60MPa.he pai te parenga wera polycarbonate, ka taea te whakamahi mo te wa roa i te - 60 ~ 120 ℃, te wera o te paheketanga o te wera 130 ~ 140 ℃, te pāmahana whakawhiti karaihe o 145 ~ 150 ℃, kaore he tohu whakarewa, i roto i te 220 ~ 230 ℃ he ahua whakarewa. .Te pāmahana whakangāwari > 310 ℃.Nā te mārō o te mekameka rāpoi, he teitei ake te pōkākā rewa i tērā o ngā thermoplastics whānui.

Taupānga:

Polycarbonates he kirihou e whakamahia whanuitia ana i roto i nga umanga hou he pai te pāmahana me te atete paanga.He tino pai tenei kirihou ki te mahi me etahi atu tikanga whakamaarama tikanga (whakarewa werohanga, tangohanga ki roto i nga ngongo, iraro ranei me te whakamaarama).Ka whakamahia ano i te wa e hiahiatia ana te maamaatanga whatu, he nui ake i te 80% te tuku ki te awhe 1560-nm (ngaru ngaru poto awhe infrared).Kua whakaōrite ngā āhuatanga ātete matū, he ātete matū ki te waikawa me te waipiro kua waimeha.He iti te parenga ki nga ketones, halogens, me nga waikawa kukū.Ko te ngoikoretanga nui e pa ana ki te polycarbonates ko te iti o te pāmahana whakawhiti karaihe (Tg> 40°C), engari kei te whakamahia tonu hei rauemi iti-iti i roto i nga punaha microfluidic me te paparanga patunga tapu hoki.
