Polybutylene terephthalate(PBT) ke semi-crystalline, thermoplastic saturated polyester, hangata e tšoeu ea lebese, e tiileng ka granular mocheso oa kamore, e atisa ho sebelisoa ha ho etsoa thepa ea bobeli ea optical cable thermoplastic.
Ho roala ha fiber secondary optical ke ts'ebetso ea bohlokoa haholo tlhahisong ea fiber optical. Ka mantsoe a bonolo feela, ho eketsa lesela le sireletsang ho optical fiber primary coating kapa buffer layer ho ka ntlafatsa bokhoni ba fiber ea optical ho hanela khatello ea nako e telele le ea radial le ho nolofalletsa ts'ebetso ea optical post-processing. Hobane thepa ea ho roala e haufi le fiber ea optical, e na le tšusumetso e kholo mosebetsing oa fiber ea optical, kahoo thepa ea ho roala e hlokeha ho ba le coefficient e nyenyane ea ho atolosa linear, crystallinity e phahameng ka mor'a extrusion, lik'hemik'hale tse ntle le botsitso ba mocheso, marako a ka hare le a ka ntle a lera la ho roala, matla a itseng a ts'ebetso le modulus ea mocha, 'me o na le mokhoa o motle oa ho sebetsa. Ho roala ka fiber hangata ho arotsoe ka mekhahlelo e 'meli: sekoahelo se hlephileng le sekoahelo se thata. Har'a tsona, thepa e hlephileng ea sheath e sebelisitsoeng ka har'a sekoaelo se hlephileng ke lera la bobeli la ho roala le fetisitsoeng sebakeng sa letsoho le hlephileng kantle ho fiber ea mantlha.
PBT ke thepa e tloaelehileng e hlephileng e nang le thepa e ntle ea ho etsa le ho e lokisa, ho monya mongobo o tlase le ts'ebetso e theko e phahameng. Haholo-holo e sebelisoang hoPBTphetoho, ho taka mohala oa PBT, casing, ho taka filimi le likarolo tse ling. PBT e na le thepa e ntle ea mochini (joalo ka ho hanyetsa ho tsieleha, ho hanyetsa ho khumama, ho hanyetsa khatello ea mahlakoreng), khanyetso e ntle ea solvent, khanyetso ea oli, k'hemik'hale ea kutu ea lik'hemik'hale, le fiber paste, paste ea cable le likarolo tse ling tsa cable li lumellana hantle, 'me li na le ts'ebetso e ntle ea ho bōpa, ho monya mongobo o tlaase, ho boloka chelete e ngata. Litekanyetso tsa eona tsa mantlha tsa ts'ebetso ea tekheniki li kenyelletsa: viscosity ea kahare, matla a tlhahiso, modulus ea ho tsitsa le ho kobeha, matla a tšusumetso (notch), coefficient ea katoloso ea mela, ho monya metsi, ho hanyetsa hydrolysis joalo-joalo.
Leha ho le joalo, ka phetoho ea sebopeho sa likhoele tsa fiber le tikoloho ea ts'ebetso, litlhoko tse ling li behiloe pele bakeng sa bushing ea fiber buffer. Khalase e phahameng, shrinkage e tlase, coefficient e tlase ea katoloso, boima bo phahameng, matla a phahameng a khatello, khanyetso e ntle ea lik'hemik'hale, ts'ebetso e ntle ea ts'ebetso, le thepa e theko e tlase ke lipheo tse phehelloang ke baetsi ba li-cable tsa optical. Hona joale, ho na le mefokolo ea kopo le theko ea beam tube e entsoeng ka thepa ea PBT, 'me linaha tsa linaheng tse ling li se li qalile ho sebelisa lisebelisoa tsa alloy PBT ho nkela thepa e hloekileng ea PBT, e nang le phello e ntle le karolo. Hajoale, lik'hamphani tse 'maloa tse kholo tsa malapeng li ntse li itokisetsa, lik'hamphani tsa thepa ea cable li hloka ntlafatso e tsoelang pele ea theknoloji, lipatlisiso le nts'etsopele ea lisebelisoa tse ncha.
Ha e le hantle, indastering ea PBT ka kakaretso, lisebelisoa tsa fiber optic cable li nka karolo e nyenyane feela ea 'maraka oa PBT. Ho ea ka mehloli ea indasteri, indastering eohle ea PBT, boholo ba karolo ea 'maraka e sebelisoa haholo-holo ke likarolo tse peli tsa likoloi le matla. Lihokelo, li-relay le lihlahisoa tse ling tse entsoeng ka thepa e fetotsoeng ea PBT li sebelisoa haholo ho likoloi, lisebelisoa tsa elektroniki le tsa motlakase, lisebelisoa tsa mochini le likarolo tse ling, esita le PBT e na le lits'ebetso sebakeng sa masela, joalo ka borokho ba borashe ba meno le bona ba entsoe ka PBT. Tse latelang ke ts'ebeliso e akaretsang ea PBT mafapheng a fapaneng:
1. Libaka tsa elektroniki le tsa motlakase
Lisebelisoa tsa PBT li sebelisoa haholo masimong a elektroniki le a motlakase, joalo ka li-sockets tsa motlakase, li-plug, li-sockets tsa elektroniki le likarolo tse ling tsa motlakase tsa malapeng. Hobane thepa ea PBT e na le ts'ebetso e ntle ea ho koala le ho hanyetsa mocheso o phahameng, e loketse haholo bakeng sa khetla, bracket, sheet sheet le likarolo tse ling tsa lisebelisoa tsa elektroniki le tsa motlakase. Ho feta moo, lisebelisoa tsa PBT li ka boela tsa sebelisoa ho etsa sekoahelo sa morao sa skrine sa LCD, khetla ea TV joalo-joalo.
2.Lebala la likoloi
Lisebelisoa tsa PBT li boetse li sebelisoa haholo tšimong ea likoloi. Ka lebaka la melemo ea eona ea mocheso o phahameng, ho senya le ho hanyetsa ho apara, lisebelisoa tsa PBT li sebelisoa haholo ha ho etsoa likarolo tsa likoloi, tse kang ho noa hangata, ntlo ea pompo ea oli, ntlo ea sensor, likarolo tsa tsamaiso ea brake, joalo-joalo Ho phaella moo, lisebelisoa tsa PBT li ka boela tsa sebelisoa bakeng sa li-headrest tsa setulo sa koloi, mekhoa ea ho fetola setulo, joalo-joalo.
3.Indasteri ea mechine
Ka indasteri ea mechine, lisebelisoa tsa PBT li atisa ho sebelisoa ho etsa lisebelisoa tsa lisebelisoa, li-switches, li-buttons, joalo-joalo thepa ea PBT e na le matla a babatsehang a mochine le ho hanyetsa ho apara, e ka mamella matla a sa tšoaneng a mechine, 'me e na le lik'hemik'hale tse ntle tsa ho senya lik'hemik'hale, tse loketseng likarolo tse sa tšoaneng tšimong ea indasteri ea mechine.
4.Indasteri ea thepa ea bongaka
Lisebelisoa tsa PBT li na le mocheso o motle oa ho hanyetsa mocheso le botsitso bo phahameng ba lik'hemik'hale, tse loketseng haholo bakeng sa tlhahiso ea lisebelisoa tsa bongaka. Ka mohlala, lisebelisoa tsa PBT li ka sebelisoa ho etsa matlo a lisebelisoa tsa bongaka, liphaephe, li-connectors, joalo-joalo Ho phaella moo, lisebelisoa tsa PBT li ka boela tsa sebelisoa ho etsa li-syringe tsa bongaka, lisebelisoa tsa infusion le lisebelisoa tse sa tšoaneng tsa phekolo.
5. Puisano ea optical
Sebakeng sa puisano ea optical, PBT e sebelisoa haholo ho optical cable ho etsa thepa e le lisebelisoa tse tloaelehileng tse hlephileng. Ho phaella moo, lisebelisoa tsa PBT li sebelisoa haholo ka lisebelisoa tsa optical. Ka lebaka la thepa ea eona e ntle ea optical le ho hanyetsa mocheso o phahameng, lisebelisoa tsa PBT li sebelisetsoa ho etsa li-optical fiber connectors, liforeimi tsa optical fiber distribution, joalo-joalo Ho phaella moo, lisebelisoa tsa PBT li ka boela tsa sebelisoa ho etsa lilense, liipone, Windows le likarolo tse ling tsa optical.
Ho ea ka pono ea indasteri eohle, lilemong tsa morao tjena, likhoebo tse amehang li ikemiselitse ho nts'etsapele mefuta e fapaneng ea ts'ebeliso ea mahlale a macha le lihlahisoa tse ncha, 'me PBT e tsoetse pele molemong oa ts'ebetso e phahameng, ts'ebetso le mefuta e fapaneng. Pure PBT resin tensile matla, ho khumama matla le ho kobeha modulus li tlaase, li ke ke tsa sebelisoa haholo lefapheng la indasteri, kahoo bakeng sa litlhoko tsa tšimo ea indasteri, indasteri ka ho fetola ho ntlafatsa ts'ebetso ea PBT. Ka mohlala, fiber ea khalase e kenngoa ho PBT - fiber ea khalase e na le melemo ea ho sebetsa ka matla, mokhoa o bonolo oa ho tlatsa le litšenyehelo tse tlaase. Ka ho eketsa fiber ea khalase ho PBT, melemo ea pele ea resin ea PBT e sebelisoa, 'me matla a tsitsitseng, matla a ho khumama le matla a ts'ebetso ea lihlahisoa tsa PBT a ntlafatsoa haholo.
Hona joale, mekhoa e ka sehloohong ea malapeng le linaheng tse ling ke phetoho ea copolymerization, phetoho ea ho tlatsa lintho tse sa tloaelehang, theknoloji ea nanocomposite, phetoho ea ho kopanya, joalo-joalo, ho ntlafatsa ts'ebetso e feletseng ea PBT. Phetoho ea lisebelisoa tsa PBT haholo-holo e shebane le likarolo tsa matla a phahameng, ho thibela lelakabe le phahameng, warpage e tlaase, pula e tlaase le dielectric e tlaase.
Ka kakaretso, mabapi le indasteri eohle ea PBT, tlhokahalo ea kopo likarolong tse sa tšoaneng e ntse e le ngata haholo, 'me liphetoho tse fapa-fapaneng ho ea ka tlhokahalo ea' maraka le tsona ke lipakane tse tloaelehileng tsa lipatlisiso le nts'etsopele ea likhoebo tsa indasteri ea PBT.
