Poly butylene Terephthalate ndi yoyera ngati yamkaka kapena yachikasu yachikasu yowoneka ngati tinthu tating'onoting'ono ta polyester ya thermoplastic. Poly butylene Terephthalate (PBT) ili ndi zida zabwino kwambiri zamakina, zida zamagetsi zamagetsi, kukana kwamafuta, kukana kwa dzimbiri kwamankhwala, kuumba kosavuta komanso kuyamwa kochepa kwa chinyezi, ndi zina zambiri, ndipo ndizinthu zomwe zimagwiritsidwa ntchito kwambiri pakupaka fiber yachiwiri.
Mu chingwe cha optical fiber, ulusi wa kuwala ndi wosalimba kwambiri. Ngakhale mphamvu yamakina ya kuwala kwa fiber imapangidwa bwino pambuyo poyambira, zofunikira za cabling sizikukwanira, kotero kuti chophimba chachiwiri chikufunika. Chophimba chachiwiri ndi njira yofunika kwambiri yotetezera makina opangira makina opangira chingwe chopangira chingwe, chifukwa chophimba chachiwiri sichimangopereka chitetezo chowonjezera pamakina kupsinjika ndi kupsinjika, komanso kumapanga kutalika kwa ulusi wa kuwala. Chifukwa cha zinthu zake zabwino zakuthupi komanso zamankhwala, Poly butylene terephthalate nthawi zambiri imagwiritsidwa ntchito ngati chinthu chowonjezera pakuphimba kwachiwiri kwa ulusi wamagetsi mu chingwe chakunja cha fiber.
Titha kupereka OW-6013, OW-6015 ndi mitundu ina ya Poly butylene Terephthalate zakuthupi kuti zokutira yachiwiri ya kuwala CHIKWANGWANI chingwe.
Zinthu za PBT zomwe tidapereka zili ndi izi:
1) Kukhazikika bwino. Sikelo yaying'ono yochepetsera, voliyumu yaying'ono ikusintha pakugwiritsa ntchito, kukhazikika kwabwino popanga.
2) Mphamvu zamakina apamwamba. Modulus yayikulu, ntchito yabwino yowonjezera, kulimba kwamphamvu kwambiri. Mtengo wa anti-lateral pressure wa chubu ndi wapamwamba kuposa muyezo.
3) Kutentha kwakukulu kosokoneza. Kuchita bwino kwambiri kosokonekera pansi pa katundu wamkulu komanso mikhalidwe yaying'ono yolemetsa.
4) Kukana kwa Hydrolysis. Ndi kukana kwambiri hydrolysis, kupanga kuwala CHIKWANGWANI chingwe moyo wautali kuposa zofunika muyezo.
5) Kukana mankhwala. Kukana kwabwino kwamankhwala komanso kuyanjana kwabwino ndi phala la fiber ndi phala la chingwe, osati zosavuta kuti ziwonongeke.
Amagwiritsidwa ntchito kwambiri popangira ❖ kuyanika kwachiwiri kwa chingwe chakunja chakunja chotayirira-chubu.
