tsebisa:
Lefapheng la lisebelisoa tse tsoetseng pele,pyromellitic dianhydride(PMDA) e atlehile e le motsoako oa bohlokoa ho etsoa ha li-resin tsa polyimide tse thibelang mocheso, lifilimi le liphahlo.Ka botsitso ba eona bo botle ba mocheso le ho feto-fetoha ha maemo, PMDA e fetohile khetho ea pele bakeng sa lits'ebetso tse ngata tse sebetsang hantle.Ka blog ena, re hlahloba bokhoni bo boholo ba li-PMDA le karolo ea bona ho fetoleng liindasteri tse fapaneng.
Maemo a sa Feleng a Mocheso:
PMDA e na le ho hanyetsa mocheso o babatsehang 'me ke thepa e tala e loketseng bakeng sa tlhahiso ea lifilimi tsa polyimide.Lifilimi tsena li sebelisoa haholo ka har'a liboto tsa potoloho tse hatisitsoeng tse feto-fetohang, bonding ea othomathike ea theipi le ho kenella ka terata ea makenete.Ka ho kenyelletsa PMDA, lisebelisoa tsena li ka mamella mocheso o feteletseng ntle le ho tela botšepehi ba tsona ba sebopeho.Lits'ebetsong moo ho kenngoa ha mocheso ho bohlokoa, lifilimi tsa polyimide tse thehiloeng ho PMDA li fana ka ts'ebetso e sa tsitsang.
Lisebelisoa tsa Powerpack:
PMDA e boetse e phetha karolo ea bohlokoa ho thehoeng ha metsoako e thehiloeng ho polyimide.Lihlopha tsena li kopanya mocheso o phahameng oa ho hanyetsa oa polyimide le matla le thepa e bobebe ea lisebelisoa tse ling.Ka lebaka leo, liindasteri tse kang sefofane, likoloi le lisebelisoa tsa elektronike li rua molemo ho nts'etsopele ea likarolo tse sebetsang hantle.Ho sa tsotellehe hore na ho hlahisa likarolo tsa lifofane kapa ho ntlafatsa ho tšoarella ha lisebelisoa tsa elektronike, metsoako e thehiloeng ho PMDA e fana ka tharollo e atlehileng.
Hardener:
Ntle le karolo ea eona ho li-resin tsa polyimide, PMDA e ka boela ea sebelisoa e le moemeli oa phekolo bakeng sa li-epoxy resin tse entsoeng ka phofo.Kopo e lumella ho theha likarolo tse ikhethileng tse kang mehele ea tiiso, li-washer tsa thrust, spacers le insulators.Ka ho eketsa PMDA e le moemeli oa phekolo, epoxy resin e ka ntlafatsa thepa ea mocheso le ea mechine, kahoo ea ntlafatsa tshebetso ea eona ka kakaretso le ho atolosa mefuta ea eona ea kopo.
Innovation Roadmap:
Thepa e ntle haholo ea PMDA e etsa hore e be motsoako oa bohlokoa molemong oa ho ntlafatsa.Liindasteri li itšetlehile ka bokhoni ba eona bo ikhethang ba ho mamella mocheso o phahameng ho netefatsa polokeho le botšepehi ba lihlahisoa tsa bona.Ka ho sutumelletsa meeli ea ho hanyetsa mocheso, li-PMDA li bula menyetla e mecha bakeng sa tsoelo-pele ea lisebelisoa tsa elektronike, sefofane, le likarolo tse ling moo ho nepahala le ho tšepahala ho leng bohlokoa.
ha re phethela:
Pyromellitic dianhydride (PMDA) ke phetoho ea 'nete tšimong ea thepa e tsoetseng pele.Ho hanyetsa mocheso oa eona o babatsehang le ho feto-fetoha ha maemo ho etsa hore e be motsoako oa bohlokoa haholo tlhahisong ea li-resin tsa polyimide, lifilimi le li-composite.Ha liindasteri li ntse li loanela ho ntlafatsa le ho ts'epahala, PMDA e fana ka motheo o hlokahalang ho sutumelletsa meeli ea ho hanyetsa mocheso.Kaha PMDA e le moetapele, re ka lebella ho bona tsoelo-pele e matla lits'ebetsong tsa ts'ebetso e phahameng, ho netefatsa boleng bo phahameng le polokeho bakeng sa lilemo tse tlang.
