I-Polybutylene terephthalate(I-PBT) yipolyester etyebileyo ye-semi-crystalline, i-thermoplastic saturated, edla ngokuba mhlophe njengobisi, i-granular solid kubushushu begumbi, isetyenziswa kakhulu ekuveliseni i-optical cable thermoplastic secondary coating material.
Ukufakwa kwe-optical fiber secondary yinkqubo ebaluleke kakhulu kwimveliso ye-optical fiber. Ngokufutshane nje, ukongeza umaleko okhuselayo kwi-optical fiber primary coating okanye kwi-buffer layer kunokuphucula amandla e-optical fiber ukumelana noxinzelelo lwe-longitudinal kunye ne-radial kwaye kube lula ukucubungula i-optical fiber emva kokusetyenziswa. Ngenxa yokuba izinto zokufaka zisondele kwi-optical fiber, zinempembelelo enkulu ekusebenzeni kwe-optical fiber, ngoko ke izinto zokufaka kufuneka zibe ne-linear expansion coefficient encinci, i-crystallinity ephezulu emva kokukhutshwa, uzinzo oluhle lweekhemikhali kunye nobushushu, iindonga ezithambileyo zangaphakathi nezangaphandle zomaleko wokufaka, amandla athile okuxinana kunye ne-Young's modulus, kwaye zisebenza kakuhle kwinkqubo. Ukufakwa kwe-fibre ngokubanzi kwahlulwe ngamacandelo amabini: isigqubuthelo esikhululekileyo kunye nesigqubuthelo esiqinileyo. Phakathi kwazo, izinto zokufaka ezikhululekileyo ezisetyenziswa kwi-loose sheath coating yi-loose sheath layer yesibini ekhutshwe kwimeko ye-loose sleeve ngaphandle kwe-optical coating fiber.
I-PBT yinto eqhelekileyo ekhululekileyo eneempawu ezintle zokuyila nokulungisa, ukufunxa umswakama omncinci kunye nokusebenza kakuhle kweendleko eziphezulu. Isetyenziswa kakhulu kwiI-PBTukuguqulwa, umzobo wentambo ye-PBT, isingxobo, umzobo wefilimu kunye nezinye iindawo. I-PBT ineempawu ezilungileyo zoomatshini (ezifana nokumelana nokutsalwa, ukumelana nokugoba, ukumelana noxinzelelo olusecaleni), ukumelana kakuhle kwe-solvent, ukumelana neoyile, ukumelana nokugqwala kweekhemikhali, kunye ne-fiber paste, i-cable paste kunye nezinye izinto zentambo zihambelana kakuhle, kwaye zisebenza kakuhle ekucwangcisweni kokubumba, ukufunxwa komswakama okuphantsi, kwaye zisebenza kakuhle. Imigangatho yayo yokusebenza yobugcisa ephambili ibandakanya: i-intrinsic viscosity, amandla okukhupha, i-tensile kunye ne-bending elastic modulus, amandla okuchaphazela (notch), i-linear expansion coefficient, ukufunxwa kwamanzi, ukumelana ne-hydrolysis njalo njalo.
Nangona kunjalo, ngotshintsho lwesakhiwo seentambo zefayibha kunye nendawo yokusebenza, kubekwe phambili iimfuno ezingaphezulu ze-fiber bushing. I-crystallization ephezulu, i-shrinkage ephantsi, i-low linear expansion coefficient, ubulukhuni obuphezulu, amandla aphezulu okuxinzelela, ukumelana okuhle kweekhemikhali, ukusebenza kakuhle kokucubungula, kunye nezixhobo ezingabizi kakhulu zezona njongo zilandelwa ngabavelisi beentambo ze-optical. Okwangoku, kukho iziphene ekusetyenzisweni nakwixabiso letyhubhu ye-beam eyenziwe ngezinto ze-PBT, kwaye amazwe angaphandle aqalise ukusebenzisa izinto ze-PBT alloy ukutshintsha izinto ze-PBT ezicocekileyo, nto leyo eye yadlala indima entle. Okwangoku, iinkampani ezininzi ezinkulu zentambo zasekhaya zilungiselela ngokukhutheleyo, iinkampani zezinto zentambo zifuna ubuchwephesha obuqhubekayo, uphando kunye nophuhliso lwezinto ezintsha.
Kakade ke, kushishino lwe-PBT iyonke, usetyenziso lweentambo ze-fiber optic luthatha inxalenye encinci yemarike ye-PBT. Ngokwemithombo yeshishini, kulo lonke ishishini le-PBT, uninzi lwesabelo semarike luhlala ikakhulu ngamacandelo amabini eemoto kunye namandla.
