Pyromellitic dianhydride(PMDA) ke motsoako o nang le mesebetsi e mengata e phethang karolo ea bohlokoa ho nts'etsopele ea li-resin tsa polyimide tse thibelang mocheso, lifilimi le liphahlo.Mehaho ea eona e ikhethang e etsa hore e be thepa e tala ea bohlokoa mefuteng e fapaneng ea ts'ebetso e phahameng, ho tloha libotong tse bonolo tse hatisitsoeng tsa potoloho ho isa ho terata ea enameled.Ha re shebisiseng bokhoni ba PMDA le phello ea eona indastering.
PMDA ke karolo e ka sehloohong ea ho hlahisa lifilimi tsa polyimide, tse tsejoang ka botsitso ba tsona bo botle ba mocheso le matla a mochine.Lifilimi tsena li sebelisoa haholo ka har'a liboto tsa potoloho tse hatisitsoeng tse feto-fetohang 'me li ka fetisa matšoao a motlakase ntle ho seam ha li ntse li mamella mocheso o phahameng.Ho phaella moo, lifilimi tsa polyimide tse thehiloeng ho PMDA ke likarolo tsa litheipi tse ikemetseng, e leng mokhoa oa bohlokoa bakeng sa kopano ea likarolo tsa elektronike.
Ho feta moo, PMDA e thusa ho theheng li-composites tse thehiloeng ho polyimide, ho ntlafatsa thepa ea tsona ea mocheso le mochini.Likarolo tsena li hlokoa haholo bakeng sa bokhoni ba tsona ba ho mamella maemo a thata a ts'ebetso, e leng se etsang hore e be tse loketseng bakeng sa lisebelisoa tsa sefofane, likoloi le lisebelisoa tsa elektroniki.Li-composite tsa polyimide tse thehiloeng ho PMDA li na le mocheso o babatsehang oa ho hanyetsa mocheso le botsitso ba sebopeho, e leng se etsang hore e be khetho ea pele libakeng tseo thepa ea setso e sa lekaneng.
Lefapheng la ho kenngoa ha terata ea enameled, PMDA e phetha karolo ea bohlokoa ho netefatsa hore nako e telele le ho tšepahala ha lisebelisoa tsa motlakase.Ka ho kenyelletsa PMDA lisebelisoa tsa ho kenya letsoho, bahlahisi ba ka etsa lithapo tse khonang ho mamella mocheso o feteletseng le maemo a thata.Sena se bohlokoa haholo liindastering tse kang ho fehla motlakase, moo tlhoko ea litharollo tse sebetsang hantle haholo e leng bohlokoa haholo.
Ho feta moo, PMDA e thusa nts'etsopele ea liphahlo tsa boleng bo holimo tse nang le khanyetso e ntle ea mocheso le ho se sebetse ha lik'hemik'hale.Liaparo tsena li na le mekhoa e fapaneng ea ts'ebeliso, ho tloha ho sireletsa lisebelisoa tsa indasteri libakeng tsa mocheso o phahameng ho ea ho fana ka lisebelisoa tse tšoarellang bakeng sa lisebelisoa tsa elektronike tsa bareki.Liaparo tse thehiloeng ho PMDA li khona ho boloka botšepehi ba tsona tlas'a khatello, li etsa hore e be thepa ea bohlokoa ho pholletsa le liindasteri tse sa tšoaneng.
Ha liindasteri li ntse li tsoela pele ho hatella meeli ea ts'ebetso le ts'epahalo, tlhoko ea PMDA e lebelletsoe ho nyoloha.E phetha karolo e ke keng ea lekanngoa ho hlahisa thepa e tsoetseng pele e sebetsang maemong a feteletseng.Ho feto-fetoha ha maemo a PMDA ho ntlafatseng thepa ea mocheso le mochini oa lihlahisoa tsa polyimide e totobatsa bohlokoa ba eona ba ho khanna boqapi ho liindasteri tse ngata.
Ka kakaretso, pyromellitic dianhydride (PMDA) ke lejoe la sekhutlo bakeng sa nts'etsopele ea lisebelisoa tse phahameng tsa ts'ebetso tse nang le khanyetso e ntle ea mocheso le botšepehi ba mechine.Tšusumetso ea eona e utloahala ho pholletsa le liindasteri ho tloha ho tsa elektronike ho ea ho sefofane, moo tlhokahalo ea litharollo tse ka tšeptjoang le tse tšoarellang li ke keng tsa buisanoa.Ha lipatlisiso le nts'etsopele li ntse li tsoela pele, PMDA e lebelletsoe ho tsoela pele ho ba mohlohlelletsi oa boqapi le ho theha bokamoso ba likopo tse sebetsang hantle.
