Poly butylene Terephthalate ke bosoeu ba lebese kapa bo mosehla bo mosehla bo fetela ho likaroloana tsa polyester tse opaque tsa thermoplastic. Poly butylene Terephthalate (PBT) e na le thepa e ntle ea mochini, thepa ea ho kenya motlakase, ho hanyetsa oli, k'hemik'hale ea kutu ea lik'hemik'hale, ho bōptjoa habonolo le ho monya mongobo o fokolang, joalo-joalo, 'me ke lisebelisoa tse sebelisoang ka ho fetisisa bakeng sa optical fiber secondary coating.
Ka mohala oa fiber optical, fiber ea optical e senyeha haholo. Le hoja matla a mochine oa fiber optical a ntlafatsoa ka mor'a ho roala ka sehloohong, litlhoko tsa cabling li ntse li sa lekana, kahoo ho roala ha bobeli hoa hlokahala. Ho roala ha bobeli ke mokhoa oa bohlokoa ka ho fetisisa oa ts'ireletso ea mochine bakeng sa fiber ea optical ka mokhoa oa tlhahiso ea optical fiber, hobane ho roala ha bobeli ha ho fane feela ka tšireletso ea mochine khahlanong le khatello le tsitsipano, empa hape ho etsa bolelele bo feteletseng ba fiber optical. Ka lebaka la litšobotsi tsa eona tse ntle tsa 'mele le lik'hemik'hale, Poly butylene terephthalate hangata e sebelisoa e le lisebelisoa tsa extrusion bakeng sa ho roala ha bobeli ba likhoele tsa optical ka ntle ho optical fiber cable.
Re ka fana ka lisebelisoa tsa OW-6013, OW-6015 le mefuta e meng ea Poly butylene Terephthalate bakeng sa ho roala ha bobeli ba mohala oa fiber optical.
Thepa ea PBT eo re faneng ka eona e na le litšobotsi tse latelang:
1) Botsitso bo botle. Sekala se senyenyane sa shrinkage, molumo o monyenyane o fetoha ha o sebelisoa, botsitso bo botle ha ho etsoa.
2) Matla a phahameng a mechine. Modulus e kholo, ts'ebetso e ntle ea katoloso, matla a phahameng a tensile. Boleng ba khatello ea anti-lateral ba tube bo phahame ho feta bo tloaelehileng.
3) Mocheso o phahameng oa ho sotha. Ts'ebetso e ntle ea ho sotha tlas'a mojaro o moholo le maemo a moroalo o monyane.
4) Ho hanyetsa ha hydrolysis. Ka khanyetso e ntle ea hydrolysis, e etsa hore thapo ea optical fiber e phele nako e telele ho feta litlhoko tse tloaelehileng.
5) Ho hanyetsa lik'hemik'hale. Ho hanyetsa lik'hemik'hale ka mokhoa o babatsehang le ho lumellana hantle le fiber paste le khoele ea cable, ha ho bonolo ho corroded.
