Polycarbonate ke eng?
Polycarbonate (PC) ke thepa ea polymer e sebelisoang haholo indastering ea lik'hemik'hale 'me ke e' ngoe ea lisebelisoa tse ratoang liindastering tse ngata ka lebaka la thepa ea eona e ikhethang ea 'mele le ea lik'hemik'hale. Sehloohong sena, re tla sekaseka ka botlalo sebopeho le thepa ea polycarbonate le mefuta e mengata ea ts'ebeliso ea eona.
1. Sebopeho sa lik'hemik'hale le sebopeho sa polycarbonate
Polycarbonate ke sehlopha sa bisphenol A (BPA) le lihlopha tsa carbonate ka karabelo ea polycondensation e hlahisoang ke polymer ea mola. Ketane ea eona ea limolek'hule e na le palo e kholo ea lihlopha tsa carbonate (-O-CO-O-), sebopeho sena se fana ka thepa ea polycarbonate e ntle haholo ea ho hanyetsa mocheso, ho pepeseha le ho hanyetsa tšusumetso. Ho tsitsa ha lik'hemik'hale tsa polycarbonate ho e nolofalletsa ho boloka thepa ea eona e sa fetohe maemong a feteletseng, e leng se etsang hore e be thepa e tšoarellang haholo.
2. Lintho tse ka sehloohong tsa polycarbonate
Lintho tse entsoeng ka polycarbonate li tsejoa ka thepa ea tsona e phahameng ea 'mele. E na le khanyetso e matla haholo, makhetlo a 250 ho feta ea khalase e tloaelehileng, e etsang hore polycarbonate e ratoe lits'ebetsong tse hlokang matla a phahameng le ho hanyetsa tšusumetso. Polycarbonate e na le mocheso o babatsehang oa ho hanyetsa mocheso, o lula o tsitsitse ho tloha ho -40 ° C ho ea ho 120 ° C, e leng se lumellang hore e sebetse hantle libakeng tse phahameng tsa mocheso. Polycarbonate e boetse e na le khanya e ntle ea optical, e fetisang ho feta karolo ea 90 lekholong ea leseli le bonahalang, kahoo hangata e sebelisoa ha ho etsoa lilense tsa optical le likoahelo tse bonaletsang.
3. Libaka tsa kopo ea polycarbonate
Ka lebaka la thepa e ikhethang ea thepa ea polycarbonate, e sebelisoa haholo liindastering tse sa tšoaneng. Ka indasteri ea kaho, polycarbonate e atisa ho sebelisoa ho etsa liphanele tse khanyang, lisebelisoa tsa marulelo le liphanele tsa acoustic. Tšusumetso e ntle ea ho hanyetsa le ho pepeseha ha eona ho etsa hore e be ea bohlokoa haholo libakeng tsena. Lefapheng la motlakase le lisebelisoa tsa elektronike, polycarbonate e sebelisoa ho etsa likarolo tsa elektroniki, matlo a lisebelisoa tsa ntlo le mekotla ea betri ka lebaka la ho hanyetsa mocheso le thepa ea ho kenya motlakase. Polycarbonate e boetse e sebelisoa haholo indastering ea likoloi, haholo-holo bakeng sa li-lampshades, lisebelisoa tsa lisebelisoa le lifensetere. Habohlokoa le ho feta, polycarbonate e boetse e sebelisoa haholo lefapheng la lisebelisoa tsa bongaka, tse kang li-syringe, lisebelisoa tsa dialysis le lisebelisoa tsa ho buoa, joalo-joalo. Likopo tsena li leboha ho se be chefo le biocompatibility ea thepa ea polycarbonate.
4. Setsoalle sa Tikoloho le se Recycled Polycarbonate
Le hoja polycarbonate e le ntho e tšoarellang le e sebetsang ka mokhoa o fapaneng, bisphenol A (BPA) e amehang tlhahisong ea eona e bakile khang e itseng ea tikoloho. Ha thekenoloji e ntse e tsoela pele, lihlahisoa tse ngata tsa polycarbonate tse se nang tikoloho li 'nile tsa ntlafatsoa tse fokotsang tšusumetso tikolohong. Ho tsosolosoa ha polycarbonate le hona ho ntse ho hapa tlhokomelo butle-butle, 'me ka ts'ebetso ea nchafatso, litšila tsa polycarbonate li ka fetoloa lihlahisoa tse ncha ho fokotsa litšila tsa lisebelisoa.
Qetello
Polycarbonate ke eng? Ke thepa ea polymer e nang le litšobotsi tse fapaneng tse phahameng, 'me e sebelisoa haholo kahong, lisebelisoa tsa elektronike le tsa motlakase, likoloi, tsa bongaka le tse ling ka lebaka la ho hanyetsa tšusumetso, ho hanyetsa mocheso, pepeneneng le botsitso ba lik'hemik'hale. Ka tlhokomeliso e ntseng e eketseha ea ts'ireletso ea tikoloho, ho tsosolosoa ha polycarbonate ho ntse ho khothaletsoa butle-butle. Polycarbonate ke thepa e sebetsang ka bobeli ebile e na le monyetla oa nts'etsopele e tsitsitseng.
