1. Isishwankathelo
Ngophuhliso olukhawulezileyo lwetekhnoloji yolwazi nonxibelelwano, iintambo zefayibha ye-optical, njengezithwali ezibalulekileyo zokudluliselwa kwedatha yanamhlanje, zijongene neemfuno ezikhulayo zokusebenza kwezinto kunye nokuthembeka kwemveliso. Ngexesha lokusebenza ixesha elide, iintambo ze-optical kufuneka zimelane noxinzelelo loomatshini, utshintsho lwendalo, kunye nokuguquguquka kobushushu, okufuna uzinzo oluphezulu, ukuqina, kunye nokuqhubekeka kokusebenza kwezinto zokwakha.
I-Polybutylene Terephthalate (PBT) yi-polymer yobunjineli ye-thermoplastic eyi-semi-crystalline, eyenziwe nge-esterification kunye ne-polycondensation ye-dimethyl terephthalate (DMT) okanye i-terephthalic acid (TPA) ene-butanediol. I-PBT yiplastiki yobunjineli yenjongo jikelele ethengiswa kade, eyaphuhliswa ngeminyaka yoo-1970 ngophuhliso olukhokelwa yi-GE Company, kodwa yakhawuleza yasetyenziswa ngokubanzi. I-PBT, kunye ne-PPO, i-POM, i-PC, kunye ne-PA, ithathwa njengenye yeeplastiki ezintlanu eziphambili zobunjineli zenjongo jikelele.
I-PBT idla ngokubonakala ngathi yimveliso ekhanyayo okanye engacacanga efana nobisi, enokuxhathisa ubushushu obuphezulu kunye neempawu ezintle zoomatshini. Ayimelani nezinyibilikisi ezininzi ze-organic kodwa ayimelani nee-asidi okanye iziseko ezinamandla; iyatsha kwaye iyabola xa kushushu kakhulu. Ulwakhiwo lwayo lweemolekyuli luquka amaqela amabini e-methylene xa kuthelekiswa ne-PET, okwenza umqolo we-helical onika izinto ukuqina okuhle kunye nokusebenza kakuhle kokucubungula.
Ngenxa yeempawu zayo ezibonakalayo ezintle, uzinzo lweekhemikhali, kunye nokukwazi ukucutshungulwa, i-PBT isetyenziswa kakhulu kumashishini ombane, eemoto, onxibelelwano, izixhobo zasekhaya, kunye nezothutho. Kwishishini leentambo zefayibha ye-optical, i-PBT isetyenziswa kakhulu ekuveliseni iityhubhu ezikhululekileyo ze-fiber optic kunye nezinto ezinxulumene nolwakhiwo.
2. Iimpawu zezinto zePBT
Ngokwenyani, i-resin ye-PBT isetyenziswa kakhulu njengemixube edityanisiweyo, kunye nezongezo ezahlukeneyo okanye idityaniswe nezinye ii-resin ukuphucula ngakumbi ukumelana nobushushu, ukubambezeleka komlilo, ukuthintela ubushushu bombane, kunye nokuzinza kokucubungula.
Iipropati Zomzimba
I-PBT inamandla aphezulu oomatshini, ukuqina, kunye nokumelana nokuguguleka, ikhusela ngokufanelekileyo imicu ye-optical ngaphakathi kweentambo kwaye inciphisa impembelelo yoxinzelelo lwangaphandle loomatshini.
Uzinzo lweeKhemikhali
I-PBT ayixhathisi kwiikhemikhali ezahlukeneyo, ifanelekile ukusetyenziswa kwiindawo ezintsonkothileyo, kwaye inceda ukuqinisekisa uzinzo oluhlala ixesha elide kwiintambo ze-optical.
Ukuqhubekeka
I-PBT kulula ukuyicubungula nge-extrusion, i-injection molding, kunye nezinye iindlela, ihlangabezana neemfuno zobukhulu kunye nokungaguquguquki kwezixhobo zekhebula le-optical.
Uzinzo lobushushu
I-PBT igcina iipropati zomzimba ezizinzileyo kumanqanaba obushushu abanzi, nto leyo eyenza ukuba ifaneleke kwiintambo ze-optical ezisebenza phantsi kweemeko ezahlukeneyo zemozulu kunye neemeko zokusingqongileyo.
3. Ukusetyenziswa okuqhelekileyo kwe-PBT kwiintambo ze-Optical
Iityhubhu ezikhululekileyo zeFiber Optic
I-PBT isetyenziswa kakhulu ekwenzeni iityhubhu ezikhululekileyo. Amandla ayo aphezulu kunye nokuqina kwayo kunika inkxaso ezinzileyo kwiifayibha ze-optical, kunciphisa umonakalo ovela ekugobeni okanye amandla okutsalwa. Iityhubhu ezikhululekileyo ze-PBT zikwabonelela ngokumelana nobushushu okugqwesileyo kunye nokusebenza kokuguga, okuqinisekisa uzinzo lwesakhiwo xa sisetyenziswa ixesha elide.
Iinxalenye zeCable Structure
Kwiindlela ezithile zoyilo lweentambo, i-PBT isetyenziselwa iindawo ezithile zesakhiwo okanye iileya zangaphandle ezisebenzayo ukuphucula ukusebenza koomatshini ngokubanzi kunye nokuziqhelanisa nokusingqongileyo.
Iibhokisi zeFiber Optic Splice kunye neeComponents ezinxulumene nazo
I-PBT ikwasetyenziswa kwiibhokisi ze-splice kunye neendawo zangaphakathi zesakhiwo, ezifuna ukutywinwa, ukumelana nemozulu, kunye nokuzinza koomatshini. Ulwakhiwo lweemolekyuli kunye neempawu zomzimba ze-PBT zenza ukuba ibe lukhetho olufanelekileyo kwezi zinto.
Izinto ekufuneka ziqwalaselwe xa kusetyenzwa
Ngaphambi kokubumba, i-PBT kufuneka yomiswe kakuhle, ngesiqhelo kwi-110–120°C kangangeeyure ezi-3. Amaqondo obushushu bokubumba ngenaliti kufuneka agcinwe kwi-250–270°C, kunye namaqondo obushushu bokubumba angama-50–75°C.
Ngenxa yobushushu obuphantsi bokutshintsha kweglasi yePBT, inyibilika ngokukhawuleza yakuba ipholile, nto leyo ebangela amaxesha amafutshane okuphola. Ukuba ubushushu be-nozzle buphantsi kakhulu, umjelo wokuhamba kwamanzi unokuqina kwaye uvale. Ukudlula kwi-275°C okanye ukuhlala ixesha elide kwezinto ezinyibilikisiweyo kwi-barrel kunokukhokelela ekuwohlokeni. Umoya ofanelekileyo wokubumba kunye neemeko zokucubungula "ngesantya esiphezulu, uxinzelelo oluphakathi, ubushushu obuphakathi" ziyacetyiswa. Iinkqubo ze-hot runner azicetyiswa kwi-PBT ethintela umlilo okanye egcwele iglasi, kwaye ii-barrel kufuneka zicocwe ngokukhawuleza nge-PE okanye i-PP emva kokuvalwa ukuthintela i-carbonization.
4. Iingenelo ze-PBT kwizicelo ze-Optical Cable
