I-Polybutylene terephthalate(I-PBT) iyi-polyester egcwele i-semi-crystalline, i-thermoplastic egcwele, ngokuvamile emhlophe njengobisi, eqinile e-granular ekushiseni kwegumbi, ivame ukusetshenziswa ekukhiqizweni kwezinto zokumboza ze-thermoplastic zekhebula le-optical.
Ukugqoka kwesibili kwe-fiber optical kuyinqubo ebaluleke kakhulu ekukhiqizweni kwe-fiber optical. Kalula nje, ukwengeza ungqimba oluvikelayo ku-primary fiber optical coating noma ungqimba lwe-buffer kungathuthukisa ikhono le-optical fiber ukumelana nokucindezeleka kwe-longitudinal kanye ne-radial futhi kube lula ukucubungula i-optical fiber ngemuva kokusebenzisa. Ngenxa yokuthi izinto zokugqoka ziseduze ne-optical fiber, zinomthelela omkhulu ekusebenzeni kwe-optical fiber, ngakho-ke izinto zokugqoka ziyadingeka ukuthi zibe ne-coefficient encane yokwandisa eqondile, i-crystallinity ephezulu ngemva kokukhipha, ukuzinza okuhle kwamakhemikhali nokushisa, izindonga zangaphakathi nezangaphandle ezibushelelezi zesendlalelo sokugqoka, amandla athile okudonsa kanye ne-modulus kaYoung, futhi zisebenza kahle ngenqubo. Ukugqoka kwe-fiber ngokuvamile kuhlukaniswe ngezigaba ezimbili: isembozo esikhululekile kanye nesembozo esiqinile. Phakathi kwazo, izinto zokugqoka ezikhululekile ezisetshenziswa ku-free sheath coating yisendlalelo sesibili sokugqoka esikhishwe esimweni se-free sleeve ngaphandle kwe-primary coating fiber.
I-PBT iyinto evamile ekhululekile enezakhiwo ezinhle kakhulu zokwakha nokucubungula, ukumuncwa komswakama okuphansi kanye nokusebenza kahle okubiza kakhulu. Isetshenziswa kakhulu kuI-PBTukuguqulwa, umdwebo wentambo ye-PBT, ikheyiji, umdwebo wefilimu kanye neminye imikhakha. I-PBT inezakhiwo ezinhle zomshini (njengokumelana nokudonswa, ukumelana nokugoba, ukumelana nengcindezi eseceleni), ukumelana okuhle kwe-solvent, ukumelana namafutha, ukumelana nokugqwala kwamakhemikhali, kanye ne-fiber paste, i-cable paste nezinye izingxenye zekhebula zinokuhambisana okuhle, futhi inokusebenza okuhle kakhulu kokucubungula ukubumba, ukumuncwa komswakama ophansi, futhi ayibizi kakhulu. Izindinganiso zayo zokusebenza zobuchwepheshe eziyinhloko zifaka: i-intrinsic viscosity, amandla okukhiqiza, i-tensile kanye ne-elastic modulus egobayo, amandla okushaya (i-notch), i-linear expansion coefficient, ukumuncwa kwamanzi, ukumelana ne-hydrolysis njalo njalo.
Kodwa-ke, ngokushintsha kwesakhiwo sekhebula le-fiber kanye nendawo yokusebenza, kuphakanyiswa izidingo ezengeziwe ze-fiber bushing bushing. Ukwakheka okuphezulu kwekristalu, ukuncipha okuphansi, i-coefficient yokukhulisa eqondile ephansi, ukuqina okuphezulu, amandla aphezulu okucindezela, ukumelana kwamakhemikhali okuhle kakhulu, ukusebenza kahle kokucubungula, kanye nezinto ezibiza kancane yizinhloso ezilandelwa abakhiqizi bekhebula le-optical. Njengamanje, kunezinkinga ekusetshenzisweni nasentengo yeshubhu le-beam elenziwe ngezinto ze-PBT, futhi amazwe angaphandle aqale ukusebenzisa izinto ze-PBT alloy ukuze athathe indawo yezinto ze-PBT ezihlanzekile, okudlale umphumela omuhle nendima. Njengamanje, izinkampani eziningana ezinkulu zekhebula zasekhaya zilungiselela ngenkuthalo, izinkampani zezinto zekhebula zidinga ukusungula izinto ezintsha kwezobuchwepheshe okuqhubekayo, ucwaningo kanye nokuthuthukiswa kwezinto ezintsha.
Vele, embonini iyonke ye-PBT, izinhlelo zokusebenza zekhebula le-fiber optic zithatha ingxenye encane kuphela yemakethe ye-PBT. Ngokusho kwemithombo yemboni, embonini yonke ye-PBT, ingxenye enkulu yesabelo semakethe ihlalwa kakhulu yimikhakha emibili yezimoto kanye namandla. Izixhumi, ama-relay kanye neminye imikhiqizo eyenziwe ngezinto ze-PBT eziguquliwe isetshenziswa kabanzi ezintweni zezimoto, zikagesi neze-elekthronikhi, imishini yemishini kanye neminye imikhakha, futhi ngisho ne-PBT inezinhlelo zokusebenza ensimini yendwangu, njengezinwele zamazinyo ezenziwe nge-PBT. Lokhu okulandelayo ukusetshenziswa okujwayelekile kwe-PBT emikhakheni eyahlukahlukene:
1. Amasimu kagesi kanye nogesi
Izinto ze-PBT zisetshenziswa kabanzi emikhakheni kagesi neye-elekthronikhi, njengezisekelo zikagesi, amapulagi, izisekelo zikagesi nezinye izingxenye zikagesi zasekhaya. Ngenxa yokuthi izinto ze-PBT zisebenza kahle ekushiseni nasekumelaneni nokushisa okuphezulu, zifaneleka kakhulu egobolondweni, ebhulokini, eshidini lokufaka ugesi kanye nezinye izingxenye zemishini kagesi neye-elekthronikhi. Ngaphezu kwalokho, izinto ze-PBT zingasetshenziswa futhi ukwenza isembozo sangemuva sesikrini se-LCD, igobolondo le-TV njalo njalo.
2. Insimu yezimoto
Izinto ze-PBT nazo zisetshenziswa kabanzi emkhakheni wezimoto. Ngenxa yezinzuzo zazo zokushisa okuphezulu, ukugqwala kanye nokumelana nokuguguleka, izinto ze-PBT zisetshenziswa kabanzi ekwakhiweni kwezingxenye zezimoto, njenge-intake manifold, i-oil pump housing, i-sensor housing, izingxenye zesistimu yamabhuleki, njll. Ngaphezu kwalokho, izinto ze-PBT zingasetshenziswa nasezindaweni zokubeka ikhanda zezihlalo zezimoto, izindlela zokulungisa izihlalo, njll.
3. Imboni yemishini
Embonini yemishini, izinto ze-PBT zivame ukusetshenziselwa ukukhiqiza izibambo zamathuluzi, izinkinobho, izinkinobho, njll. Izinto ze-PBT zinamandla amakhulu okusebenza kanye nokumelana nokuguguleka, zingamelana namandla ahlukahlukene okusebenza, futhi zinokumelana okuhle nokugqwala kwamakhemikhali, ezifanele izingxenye ezahlukene emkhakheni wemboni yemishini.
4. Imboni yemishini yezokwelapha
Izinto ze-PBT zinokumelana okuhle nokushisa okuphezulu kanye nokuqina kwamakhemikhali okuphezulu, okulungele kakhulu ukukhiqizwa kwamadivayisi ezokwelapha. Isibonelo, izinto ze-PBT zingasetshenziswa ukwenza izindawo zokugcina amadivayisi ezokwelapha, amapayipi, izixhumi, njll. Ngaphezu kwalokho, izinto ze-PBT zingasetshenziswa futhi ukwenza amasirinji ezokwelapha, amasethi okufakwa kanye nezinsimbi zokwelapha ezahlukahlukene.
5. Ukuxhumana okubonakalayo
Emkhakheni wokuxhumana kwe-optical, i-PBT isetshenziswa kabanzi ekukhiqizweni kwekhebula le-optical njengento evamile ekhululekile. Ngaphezu kwalokho, izinto ze-PBT zisetshenziswa kabanzi kumadivayisi e-optical. Ngenxa yezakhiwo zayo ezinhle ze-optical kanye nokumelana nokushisa okuphezulu, izinto ze-PBT zisetshenziselwa ukwenza izixhumi ze-optical fiber, ozimele bokusabalalisa i-optical fiber, njll. Ngaphezu kwalokho, izinto ze-PBT zingasetshenziswa futhi ukwenza amalensi, izibuko, amafasitela nezinye izingxenye ze-optical.
Ngokombono womkhakha wonke, eminyakeni yamuva nje, amabhizinisi afanele azibophezele ekuthuthukiseni ukusetshenziswa okuhlukahlukene kobuchwepheshe obusha nemikhiqizo emisha, kanti i-PBT ithuthuke ngendlela yokusebenza okuphezulu, ukusebenza kanye nokwehlukahluka. Amandla okudonsa e-resin ye-PBT emsulwa, amandla okugoba kanye ne-modulus yokugoba aphansi, awakwazi ukusetshenziswa kabanzi emkhakheni wezimboni, ngakho-ke ngezidingo zensimu yezimboni, imboni ngokuguqulwa ukuze kuthuthukiswe ukusebenza kwe-PBT. Isibonelo, i-fiber yengilazi yengezwa ku-PBT - i-fiber yengilazi inezinzuzo zokusetshenziswa okuqinile, inqubo elula yokugcwalisa kanye nezindleko eziphansi. Ngokufaka i-fiber yengilazi ku-PBT, izinzuzo zokuqala ze-resin ye-PBT ziyasetshenziswa, futhi amandla okudonsa, amandla okugoba kanye namandla okuthinta i-notch yemikhiqizo ye-PBT athuthukiswa kakhulu.
Njengamanje, izindlela eziyinhloko ekhaya nakwamanye amazwe ukuguqulwa kwe-copolymerization, ukuguqulwa kokugcwaliswa kwezinto ezingaphili, ubuchwepheshe be-nanocomposite, ukuguqulwa kokuxuba, njll., ukuthuthukisa ukusebenza okuphelele kwe-PBT. Ukuguqulwa kwezinto ze-PBT kugxile kakhulu ezicini zamandla aphezulu, i-langabi eligcina ilangabi liphezulu, i-warpage ephansi, imvula ephansi kanye ne-dielectric ephansi.
Ngokuvamile, maqondana nomkhakha wonke we-PBT, isidingo sokusetshenziswa emikhakheni ehlukahlukene sisabalulekile kakhulu, futhi izinguquko ezahlukahlukene ngokwesidingo semakethe nazo ziyimigomo evamile yocwaningo nentuthuko yamabhizinisi embonini ye-PBT.
