Lebitso la Sehlahiswa:polycarbonated

Sebopeho sa molek'hule:C31H32O7

Nomoro ea CAS:25037-45-0

Sehlahisoa sebopeho sa molek'hule:

Lintho tsa Lik'hemik'hale:

Polycarbonateke amorphous, tasteless, odorless, non-chefo transparent thermoplastic polymer, e na le thepa e babatsehang ea mechine, e futhumatsang le ea motlakase, haholo-holo ho hanyetsa matla, ho thatafala, ho phunyeha ho nyenyane, boholo ba sehlahisoa bo tsitsitse.Matla a eona a ts'ebetso ea 44kj / mz, matla a tensile> 60MPa.ho hanyetsa mocheso oa polycarbonate ho molemo, ho ka sebelisoa nako e telele ho - 60 ~ 120 ℃, mocheso oa ho kheloha mocheso 130 ~ 140 ℃, mocheso oa khalase oa 145 ~ 150 ℃, ha ho na ntlha e qhibilihisitsoeng, ka 220 ~ 230 ℃ ke boemo bo qhibilihisitsoeng. .Mocheso oa ho bola oa mocheso> 310 ℃.Ka lebaka la ho tiea ha ketane ea limolek'hule, viscosity ea eona e qhibilihang e phahame haholo ho feta ea thermoplastics e akaretsang.

Kopo:

Polycarbonates ke lipolasetiki tse sebelisoang haholo indastering ea sejoale-joale tse nang le mocheso o motle le ho hanyetsa tšusumetso.Polasetiki ena e ntle haholo ho sebetsa ka mekhoa e tloaelehileng ea ho hlalosa (ho bopa ka ente, extrusion ka har'a li-tubes kapa cylinders le thermoforming).E boetse e sebelisoa ha ho hlokahala ponaletso ea optical, e nang le phetiso e fetang 80% ho fihlela ho 1560-nm range (short wave infrared range).E na le mekhoa e itekanetseng ea ho hanyetsa lik'hemik'hale, e hanyetsanang le lik'hemik'hale ho acid e hlapolotsoeng le joala.Ha e hanyetsane hantle le li-ketone, li-halogen, le li-acid tse ngata.Phoso e kholo e amanang le polycarbonates ke mocheso o tlase oa phetoho ea likhalase (Tg> 40 ° C), empa e ntse e sebelisoa haholo joalo ka thepa e theko e tlase lits'ebetsong tsa microfluidic hape e le lesela la sehlabelo.
