I-Polybutylene terephthalate(PBT) iyi-semi-crystalline, i-thermoplastic saturated polyester, ngokuvamile emhlophe njenge-milky, i-granular eqinile ekamelweni lokushisa, ivame ukusetshenziswa ekukhiqizeni okokusebenza kwe-optical cable thermoplastic secondary coating.
I-Optical fibre enamathelayo iyinqubo ebaluleke kakhulu ekukhiqizeni i-fiber optical. Ukukhuluma nje, ukungeza isendlalelo esivikelayo ku-optical fibre primary coating noma isendlalelo se-buffer kungathuthukisa ikhono le-optical fiber ukumelana nokucindezeleka kwe-longitudinal ne-radial futhi kusize ukucutshungulwa kwe-fiber optical post-processing. Ngenxa yokuthi izinto zokumboza ziseduze ne-fiber optical, inomthelela omkhulu ekusebenzeni kwe-fiber optical, ngakho-ke impahla yokumboza iyadingeka ukuze ibe ne-coefficient encane yomugqa wokwandisa, i-crystallinity ephezulu ngemva kokukhishwa, ukuqina okuhle kwamakhemikhali nokushisa, izindonga ezibushelelezi zangaphakathi nangaphandle zesendlalelo sokumboza, amandla athile aqinile kanye ne-modulus yokusebenza okuhle kwe-Young's. I-fiber coating ngokuvamile ihlukaniswe ngezigaba ezimbili: ikhava evulekile kanye nekhava eqinile. Phakathi kwazo, i-loose sheath material esetshenziswa ku-loose sheath coating iyisendlalelo sesibili sokumboza esikhishwe esimweni semikhono evulekile ngaphandle kwe-fiber yokuqala yokunamathela.
I-PBT iyinto evamile emikhono evulekile enezakhiwo ezinhle kakhulu zokwakha nokucubungula, ukumunca umswakama ophansi nokusebenza kwezindleko eziphezulu. Isetshenziswa kakhulu kuI-PBTukuguqulwa, umdwebo wezintambo ze-PBT, i-casing, umdwebo wefilimu nezinye izinkambu. I-PBT inezinto ezinhle zomshini (ezifana nokumelana nokuqina, ukumelana nokugoba, ukumelana nokucindezela ohlangothini), ukumelana okuhle kwe-solvent, ukumelana nowoyela, ukumelana nokugqwala kwamakhemikhali, nokunamathisela kwe-fiber, ukunamathisela kwekhebula nezinye izingxenye zekhebula kunokuhambisana okuhle, futhi inomsebenzi omuhle kakhulu wokucubungula ukubumba, ukumuncwa komswakama ophansi, ukonga imali. Izindinganiso zayo eziyinhloko zokusebenza kwezobuchwepheshe zihlanganisa: i-viscosity yangaphakathi, amandla esivuno, i-tensile futhi igoba i-modulus elastic, amandla omthelela (i-notch), i-coefficient yokunwetshwa komugqa, ukumuncwa kwamanzi, ukumelana ne-hydrolysis nokunye.
Kodwa-ke, ngokushintshwa kwesakhiwo sekhebula le-fiber kanye nendawo yokusebenza, izidingo ezengeziwe zibekwa phambili ze-fiber buffer bushing. I-crystallization ephezulu, ukushwabana okuphansi, i-coefficient ephansi yomugqa wokwandisa, ukuqina okuphezulu, amandla acindezelayo aphezulu, ukumelana namakhemikhali okuhle kakhulu, ukusebenza kahle kokucubungula, nezinto ezingabizi kakhulu kuyimigomo elandelwa abakhiqizi bezintambo ezibonakalayo. Njengamanje, kukhona ukushiyeka ekusetshenzisweni kanye nentengo ye-tube ye-beam eyenziwe ngezinto ze-PBT, futhi amazwe angaphandle aseqalile ukusebenzisa izinto ze-PBT alloy ukuze athathe indawo yezinto ezihlanzekile ze-PBT, eziye zadlala umphumela omuhle kanye nendima. Njengamanje, izinkampani eziningana ezinkulu zamakhebula zasekhaya zilungiselela ngenkuthalo, izinkampani zezinto zamakhebula zidinga ukuthuthukiswa okuqhubekayo kwezobuchwepheshe, ucwaningo nokuthuthukiswa kwezinto ezintsha.
Kunjalo, kuyo yonke imboni ye-PBT, izinhlelo zokusebenza zekhebula le-fiber optic zithatha ingxenye encane yemakethe ye-PBT. Ngokwemithombo yemboni, kuyo yonke imboni ye-PBT, ingxenye enkulu yesabelo semakethe ithathwa kakhulu yizinkambu ezimbili zezimoto namandla. Izixhumi, ama-relay neminye imikhiqizo eyenziwe ngezinto ze-PBT ezishintshiwe zisetshenziswa kakhulu ezintweni zezimoto, zikagesi nezikagesi, okokusebenza kwemishini neminye imikhakha, futhi ne-PBT inezinhlelo zokusebenza emkhakheni wendwangu, njengama-bristles wezixubho nazo zenziwe nge-PBT. Okulandelayo ukusetshenziswa okuvamile kwe-PBT emikhakheni eyahlukene:
1.Izinkundla zikagesi nezikagesi
Izinto ze-PBT zisetshenziswa kakhulu ezindaweni zikagesi nezikagesi, njengezisekelo zamandla, amapulaki, amasokhethi kagesi nezinye izingxenye zikagesi zasendlini. Ngenxa yokuthi impahla ye-PBT inokusebenza okuhle kokufakwa kwe-insulation kanye nokumelana nokushisa okuphezulu, ifaneleka kakhulu igobolondo, ubakaki, i-insulation sheet nezinye izingxenye zemishini kagesi nekagesi. Ngaphezu kwalokho, izinto ze-PBT zingasetshenziswa ukwenza ikhava yangemuva yesikrini se-LCD, igobolondo le-TV nokunye.
2.Inkundla yezimoto
Izinto ze-PBT nazo zisetshenziswa kabanzi emkhakheni wezimoto. Ngenxa yezinzuzo zayo zokushisa okuphezulu, ukugqwala nokumelana nokugqoka, izinto ze-PBT zisetshenziswa kabanzi ekwakhiweni kwezingxenye zezimoto, njenge-intake manifold, i-oil pump housing, i-sensor housing, izingxenye zesistimu ye-brake, njll. Ngaphezu kwalokho, izinto ze-PBT zingasetshenziswa futhi kuma-headrests ezihlalo zemoto, izindlela zokulungisa izihlalo, njll.
3.Imboni yemishini
Embonini yemishini, izinto ze-PBT zivame ukusetshenziselwa ukukhiqiza izibambo zamathuluzi, ukushintshwa, izinkinobho, njll. Impahla ye-PBT inamandla amahle kakhulu okusebenza kanye nokumelana nokugqoka, ingamelana namandla ahlukahlukene emishini, futhi inokumelana nokugqwala kwamakhemikhali okuhle, okufanelekile izingxenye ezihlukahlukene emkhakheni wemboni yemishini.
4.Imboni yemishini yezokwelapha
Impahla ye-PBT inokumelana okuhle kokushisa okuphezulu kanye nokuzinza okuphezulu kwamakhemikhali, okulungele kakhulu ukukhiqizwa kwemishini yezokwelapha. Isibonelo, izinto ze-PBT zingasetshenziswa ukwenza izindlu zedivayisi yezokwelapha, amapayipi, izixhumi, njll. Ngaphezu kwalokho, izinto ze-PBT zingasetshenziswa ukwenza amasirinji ezokwelapha, amasethi okumnika kanye nezinsimbi ezihlukahlukene zokwelapha.
5. Ukuxhumana optical
Emkhakheni wokuxhumana optical, i-PBT isetshenziswa kakhulu ekukhiqizeni ikhebula le-optical njengento evamile yomkhono oxekethile. Ngaphezu kwalokho, izinto ze-PBT zisetshenziswa kakhulu kumadivayisi optical. Ngenxa yezakhiwo zayo ezinhle ze-optical kanye nokumelana nokushisa okuphezulu, izinto ze-PBT zisetshenziselwa ukwenza izixhumi ze-fiber optical, amafreyimu okusabalalisa i-fiber optical, njll. Ngaphezu kwalokho, izinto ze-PBT zingasetshenziswa futhi ukwenza ama-lens, izibuko, i-Windows nezinye izingxenye ze-optical.
Ngokombono wayo yonke imboni, eminyakeni yamuva, amabhizinisi afanelekile azibophezele ekuthuthukiseni ukusetshenziswa okuhlukahlukene kobuchwepheshe obusha nemikhiqizo emisha, futhi i-PBT iye yathuthukiswa ngendlela yokusebenza okuphezulu, ukusebenza nokuhlukahluka. Amandla e-resin ahlanzekile e-PBT, amandla okugoba kanye ne-modulus egobayo aphansi, angeke asetshenziswe kabanzi emkhakheni wezimboni, ngakho-ke ngezidingo zensimu yezimboni, imboni ngokuguqulwa kokuthuthukisa ukusebenza kwe-PBT. Isibonelo, i-glass fiber yengezwe ku-PBT - i-glass fiber inezinzuzo zokusebenzisa okuqinile, inqubo yokugcwalisa elula kanye nezindleko eziphansi. Ngokungeza i-glass fiber ku-PBT, izinzuzo zangempela ze-PBT resin ziyasetshenziswa, futhi amandla aqinile, amandla okugoba namandla omthelela we-notch wemikhiqizo ye-PBT athuthukiswa kakhulu.
Njengamanje, izindlela eziyinhloko ekhaya nakwamanye amazwe ukuguqulwa kwe-copolymerization, ukuguqulwa kokugcwalisa izinto ezingaphili, ubuchwepheshe be-nanocomposite, ukuguqulwa kokuxuba, njll, ukuthuthukisa ukusebenza okuphelele kwe-PBT. Ukuguqulwa kwezinto ze-PBT ngokuyinhloko kugxile ezicini zamandla aphezulu, i-flame retardant ephezulu, i-warpage ephansi, imvula ephansi kanye ne-dielectric ephansi.
Ngokuvamile, ngokuphathelene nayo yonke imboni ye-PBT, isidingo sokufaka izicelo emikhakheni ehlukahlukene sisakhulu kakhulu, futhi ukuguqulwa okuhlukahlukene ngokwesidingo semakethe nakho kuyizinjongo ezivamile zocwaningo nentuthuko zamabhizinisi emboni ye-PBT.
