Product Name:polycarbonated

Molecular format:C31H32O7

CAS nhamba:25037-45-0

Chigadzirwa chemolecular chimiro:

Chemical Properties:

Polycarbonateis an amorphous, isingaravike, haina kunhuwa, isiri-chepfu transparent thermoplastic polymer, ine yakanakisa mechanical, thermal uye magetsi zvimiro, kunyanya kukanganisa kupikisa, kusimba kwakanaka, kukambaira kudiki, saizi yechigadzirwa yakagadzikana.Yayo notched simba simba re44kj / mz, tensile simba> 60MPa.polycarbonate heat resistance yakanaka, inogona kushandiswa kwenguva yakareba pa - 60 ~ 120 ℃, tembiricha yekupisa 130 ~ 140 ℃, tembiricha yegirazi ye145 ~ 150 ℃, hapana inonyungudika iri pachena, mu220 ~ 230 ℃ yakanyunguduka. .Thermal decomposition tembiricha > 310 ℃.Nekuda kwekuoma kweiyo molecular cheni, kunyungudika kwayo kunyunguduka kwakakwira zvakanyanya kupfuura iyo ye general thermoplastics.

Application:

Polycarbonates mapurasitiki anoshandiswa zvakanyanya muindasitiri yemazuva ano ane tembiricha yakanaka uye inopikisa kuramba.Plastiki iyi inonyanya kunaka kushanda nemamwe maitiro ekutsanangura (jekiseni kuumba, extrusion mumachubhu kana masilinda uye thermoforming).Inoshandiswawo kana optical transparency ichidikanwa, iine anopfuura 80% kutapurirana kusvika ku1560-nm renji (short wave infrared range).Iyo ine moderated chemical resistance properties, ichidzivirira kemikari kune diluted acids uye doro.Iyo haina kumira zvakanaka pakurwisa ketoni, halogens, uye concentrated acids.Chinhu chikuru chakashata chine chekuita nepolycarbonates tembiricha yegirazi yepasi (Tg> 40°C), asi ichiri kushandiswa zvakanyanya sezvinhu zvinodhura mumamicrofluidic system uye sechibairo.
