PAGYTY PLASTICS: Lisebelisoa tse phahameng tsa ts'ebetso li kopanya ntlafatso le ts'ebeliso
Polyimide (pi) ke polasetiki e ikhethang e nang le thepa e ikhethang e leng bohlokoa indastering e fapaneng ka lebaka la khatello ea mocheso e phahameng haholo ea mocheso o moholo oa ho hanyetsa, khatello ea motlakase le thepa ea motlakase. Ho tloha Aerospace ho elektroniki ho ea lisebelisoa tsa likoloi le lisebelisoa, lits'ebetso tsa pi li pharaletse ebile li fapane. Sehloohong sena, re tla nka tsela e ka tlase ea ho sheba thepa ea polasetiki ea PI Refinty le hore na ba sebelisoa joang indastering ea sejoale-joale.
E 'ngoe ea thepa e qobellang e ileng ea matlafatsa ka ho fetisisa ea Tai ea Plasttics ke ho hanyetsa mochesong a phahameng. Bokhoni ba ho mamella mocheso oa nako e telele ho isa ho nako ea nako e telele, 'me ho feta Celsius ka nako e telele, e etsa hore Piels ea morao-rao a sebetse ka maemo a mocheso. Ka mohlala, karolong ea Aerospace, Pi e sebelisoa ho etsoa likarolo tsa enjini tsa enjene, litheko tsa futhumatsang le likarolo tsa sebopeho.
Ntle le khaello ea eona e phahameng ea mocheso oa eona o phahameng, PI o na le thepa e ntle haholo ea motlakase oa motlakase. Matla a eona a ho boloka thepa e tsitsitseng ea motlakase ka har'a lithemparetjha tse fapaneng le maqhubu a atisang likopo tse ngata tsa likopo tsa elektroniki. , har'a tse ling.
Lifate tsa PlasticTy le tsona li na le thepa e ntle e ntle ea ho aka, ho kenyelletsa matla le matla a tšohileng, ho thata le ho ba thata. Mesebetsi ena e lumella PI ho ipabola ka ho batla likopo tsa sebopeho joalo ka li-get tse ntle, litiiso, litiiso tsa indasteri ea likoloi. Ntle le moo, ho hanyetsa ha PI's Ho hanyetsa le ho lumellana le khohlano e tlase ho etsa hore e be thepa e loketseng bakeng sa likarolo tse thellang le tse tsamaeang.
Lefapheng la bongaka, ho itlopa joala ho honyenyane le ho pakisoa ha lik'hemik'hale ho etsa hore ho be loketse lisebelisoa tsa bongaka tse fapaneng tsa bongaka, tse ntle tsa tsebo ea bohlooho. .
Tikoloho, Plasticty Plastics le eona e ikamahanya le maemo a tikoloho. Ho hanyelleloa lik'hemik'hale tse ngata le tsa lik'hemik'hale tse hohelang, ho kopanyelletsa le li-acids, alkalis le li-sollys. Ka lebaka leo, PI e na le likopo tse fapaneng tsa likotlo tsa popi, litanka le lijana tsa ho sebetsa lik'hemik'hale le liiikeng tsa peterchemical.
Leha e le melemo e mengata, lithoto tsa polasetiki ea PI li na le meeli, joalo ka ho sebetsa ka thata le litšenyehelo tse phahameng. Leha ho le joalo, mathata ana a ntse a hlaphoheloa butle-butle joalo ka boiketlo ba mahlalehla a theknoloji, a lumellang PI hore e sebelisoe ka mefuta e mengata e ntseng e eketseha ea lits'ebetso.
Ka kakaretso, polasetiki ea Pép ha li fetohe, thepa ea tšebetso e phahameng ea boitšoaro bo matla ka ho tsitsa ea mocheso o moholo, le thepa ea motlakase e entseng tse tsebahalang indastering e ngata. Ebang ke likopo tsa aerospace libakeng tse feteletseng kapa ka lisebelisoa tsa motlakase, PI e bontšitse boleng ba eona ba keretse. Ha re ntse re etsa lipatlisiso tse ling mabapi le polao ea platics le ho qalisoa ha Mahlalelong.
Sebopeho le ts'ebeliso ea lisebelisoa tse ikhethang tsa PI
Polyimide (polyimide Libaka tse ngata tsa Thecilecnics tsa boholo ba Li-microlectonic li hloka lisebelisoa tsa elektroniki ho sebetsa hantle mme ka tloaelo ts'ebetsong ea lisebelisoa tsa PI li ka fihlela boemo bona. E ntse e ka sebelisoa ha e feta 300 ℃, e lekaneng bakeng sa theknolo ea mocheso. Haholo-holo e sebelisoang likhomphutha, mochini mabone a sehlopha, lisebelisoa tsa puisano le joalo.
Lipuo tsa likopi tsa likopi tsa likokoana-hloko ke senotlolo sa indasteri ea tlhahisoleseling ea Chaena. Ho kenyelletsa Aerospace, ho ba le maikutlo ka ho fetisisa, ho ba le puisano, ho ka sebelisoa marang-rang a khomphutha le lisebelisoa tsa lapeng. PI ke e 'ngoe ea lisebelisoa tse sebelisoang haholo li le khoebong ea likokoana-hloko, tse thathamisitsoeng e le boemo bo boholo ba lekholo la bo21si, ba lula tempeleng ea likopi tsa likonyana tsa microlectoronic. Mahlale a likopitsi a ipapisitse le lipotoloho tse kopaneng le mefuta e fapaneng ea lisebelisoa tsa semicondtor tse thehiloeng theknoloji ea elektroniki e phahameng. E tšoauoa ka boholo bo bonyenyane, boima bo bobebe, botumo bo phahameng le bo potlakileng bo potlakileng ba ho sebetsa. Le lisebelisoa tsa pi li ka kopana le thepa ena.
Lisebelisoa tse khethehileng tsa pi li na le thepa e ntle. Matla a mashome a mane a ho fihlela 100mpa kapa ho feta, pi tšusumetso ea ho fihlela 261kj / m, ho se bonolo ho senyeha ha ho sithabela ho ba le khatello ea maikutlo. Bokhoni ba ho hanela bo-raputo le ho robeha bo ka khanna ts'ebetso e ntle ea lisebelisoa tsa elektroniki sethaleng hamorao. E sebelisoang ho lihlahisoa tsa elektroniki, lik'homphieutha tsa mantlha le masimo a mang.
Polyimide e na le thepa e ntle ea lefu la liketsahalo. Melemo e metle ea motlakase ea motlakase, mokhoa oa ho etsa joalo o ka ba ka 3.4, matla a etsang mekhoa ea lijo tsa 100-300 kV / mm. Mesebetsi ena ea thepa e bolokiloe boemong bo phahameng holim'a mocheso o pharalletseng le khafetsa. Mohlala, motlakase o tloaelehile haholo ho tšimong ea likokoana-hloko. Ts'ebeliso ea lisebelisoa tsa PI e thibela motlakase oa lipalo 'me o fumana tekanyo ea polokeho. Ke ts'ebeliso e ntle haholo tšimong ea elektroniki.
Ts'ebeliso ea lisebelisoa tsa PI e ntse e se e le phara ebile e pharaletse. Ts'ebetso ea eona e felletseng e felletseng, khopolo e ntle, e matlafatsang, mocheso o phahameng oa ho etsa likopi tsa likokoana-hloko, Aerospace le masimo a mang. Ka nako e ts'oanang, matla a macha, semicondtor le indasteri e meng ka tlhoko ea lisebelisoa tsa PI le tsona li tla hola.
Li-Plastics tse khethehileng ka har'a semiconductor le lits'ebetso tsa indasteri ea microectics indasteri
Litaba tse khethehileng tsa Pilemictor li indasteri le senotlolo sa indasteri ea kokoana-hloko ea Micronecronic ke indasteri ea tlhahisoleseling. Ho kenyelletsa le Aerospace, Ho ba le likhokahano tse hole, ho ba le puisano le lisebelisoa tsa khomphutha le lisebelisoa tsa lapeng li tla sebelisa saculectics. Ntho ea bohlokoa ke hore hangata ntho e bonahalang e hlaha indastering ea likoekoetsi, ke hore, thepa e tšepisang ea likokoana-hloko, e nkang mahlale a likopi tsa takei tsa likoe tsa microlecronics.
Mahlale a likopi tsa likokoana-hloko ke litlaleho tse kholo tse nang le lipotoloho tse kopaneng e le senotlolo le lisebelisoa tse fapaneng tsa secouctor e le motheo. E tšoauoa ka boholo bo bonyenyane, boima bo bobebe, botumo bo phahameng le bo potlakileng bo potlakileng ba ho sebetsa. Ke lintho tse bonahalang tse ka fihlelang thepa ena.
Lisebelisoa tsa pi li na le khatello e phahameng ea mocheso. Lihlahisoa tse ngata tsa theknolorikeche tsa Sekhethesi li hloka lisebelisoa tsa elektroniki libakeng tse thata, tse tsitsitseng, tse tloaelehileng. Ts'ebetso ea lisebelisoa tsa pi li ka fihlela boemo bona. Taba ea hore ba ntse ba ka sebelisoa mochesong o ka holimo ho 300 ° C o lekane bakeng sa likokoana-hloko tse hlokang ts'ebetso ea mocheso o phahameng. Tlhokahalo ea ho sebelisoa likhomphutha, projeka ea botsela, lisebelisoa tsa puisano, jj ..
Lisebelisoa tsa pi li na le thepa e ntle ea ho alima. Matla a mashome a masoneng a ka fihlela ho 100mpa, matla a tšusumetso a PI a ho 261kj / m, e se bonolo ho hanela matla a ka ntle, 'me e na le bokhoni ba ho hanela botsitso ha e le matla. Ho hanyetsa Deformation, ho robeha le likarolo tse ling tsa bokhoni ba ho khanna ts'ebetso e ntle ea lisebelisoa tsa elektroniki bothaleng ba morao. E sebelisoang ho lihlahisoa tsa elektroniki, lik'homphieutha tsa mantlha le masimo a mang.
Lintho tse bonahalang li na le pokomo e ntle, e nang le thepa e ntle ea lefu la liketsahalo. Melemo e metle ea motlakase ea motlakase, mokhoa o sa khaotseng Ka lebaka la mocheso o pharalletseng le khafetsa, thepa ena e ntse e ka bolokoa boemong bo phahameng. Mohlala, motlakase o tloaelehile haholo ho tšimong ea likokoana-hloko. Ts'ebeliso ea lisebelisoa tsa pi e khona ho thibela motlakase oa lipalo ebe o fumana tekanyo ea polokeho. Ke ts'ebeliso e ntle haholo tšimong ea elektroniki.
Libaka tsa kopo tsa lisebelisoa tsa PI le tsona lia hola. Ka ts'ebetso ea eona e ntle, koeho e ntle, ea ho hanyetsa mocheso o phahameng le litšobotsi tse ling, e ka khothaletsa pokello ea li-microlectics. Sebaka sa indasteri le tšimo ea Aerospace ke libaka tsa ts'ebeliso moo lisebelisoa tsa pi li sebelisoang ho tsona ka bongata haholo. Khabareng, tlhoko ea lisebelisoa tsa Pipi ka matla a macha ea POI le indasteri e meng li tla tsoela pele ho hola.
