Polybutylene Terephthalate (PBT)
Polybutylene Terephthalate (PBT)
Chiyambi cha Zamalonda
Polybutylene Terephthalate ndi tinthu ta polyester toyera ngati mkaka kapena tachikasu tomwe timawala ngati thermoplastic. Polybutylene Terephthalate (PBT) ili ndi mphamvu zabwino kwambiri zamakaniko, mphamvu zamagetsi zotetezera kutentha, mphamvu ya mafuta, mphamvu ya mankhwala yolimbana ndi dzimbiri, kupangika mosavuta komanso kuyamwa chinyezi chochepa, ndi zina zotero, ndipo ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri popanga utoto wachiwiri wa ulusi wa kuwala.
Mu chingwe cha ulusi wowala, ulusi wowala ndi wofooka kwambiri. Ngakhale kuti mphamvu ya makina ya ulusi wowala imakula pambuyo pa chophimba choyamba, zofunikira pakulumikiza mawaya sizikwanira, kotero chophimba chachiwiri chikufunika. Chophimba chachiwiri ndi njira yofunika kwambiri yotetezera ulusi wowala popanga chingwe cha ulusi wowala, chifukwa chophimba chachiwiri sichimangopereka chitetezo chamakina ku kupsinjika ndi kupsinjika, komanso chimapanga kutalika kochulukirapo kwa ulusi wowala. Chifukwa cha mphamvu zake zabwino zakuthupi ndi zamankhwala, Poly butylene terephthalate nthawi zambiri imagwiritsidwa ntchito ngati chinthu chotulutsira chophimba chachiwiri cha ulusi wowala mu chingwe chakunja cha ulusi wowala.
Tikhoza kupereka OW-6013, OW-6015 ndi mitundu ina ya zinthu za Poly butylene Terephthalate kuti zigwiritsidwe ntchito popangira chingwe cha optical fiber.
makhalidwe
Zinthu zomwe tapereka za PBT zili ndi makhalidwe awa:
1) Kukhazikika bwino. Kuchepa pang'ono kwa chitsulo, kusintha pang'ono kwa voliyumu pogwiritsira ntchito, kukhazikika bwino popanga.
2) Mphamvu yayikulu ya makina. Modulus yayikulu, magwiridwe antchito abwino owonjezera, mphamvu yayikulu yogwira. Mphamvu yotsutsana ndi mbali ya chubu ndi yayikulu kuposa muyezo.
3) Kutentha kwakukulu kosokoneza. Kugwira ntchito bwino kwambiri kosokoneza zinthu pakakhala katundu wambiri komanso katundu wochepa.
4) Kukana kwa hydrolysis. Ndi kukana kwabwino kwambiri kwa hydrolysis, zomwe zimapangitsa kuti chingwe cha ulusi wa kuwala chikhale ndi moyo wautali kuposa zofunikira zonse.
5) Kukana mankhwala. Kukana mankhwala bwino kwambiri komanso kugwirizana bwino ndi ulusi wa ulusi ndi chingwe cha waya, sizivuta kuzimiririka.
Kugwiritsa ntchito
Amagwiritsidwa ntchito makamaka popanga utoto wachiwiri wa ulusi wa kuwala wa chingwe chakunja cha ulusi wa kuwala.
