Mtundu ndi kugwiritsa ntchito
Mtundu | Zogulitsa | Ntchito ndi ubwino |
Chithunzi cha GL3019 | PBT utomoni | Zida Zoyatira Zachiwiri Zogwiritsidwa Ntchito pa Optical Fiber |
Mafotokozedwe Akatundu
PBT ndizofunikira kwambiri zokutira zachiwiri za Optical Fiber, Imakhala ndi magwiridwe antchito abwino kwambiri pamakina / matenthedwe / hydrolytic / kukana kwamankhwala komanso kosavuta kukonzedwa ndi makina.
Katundu | Ubwino wake | Kufotokozera |
Zimango katundu | Kukhazikika kwakukulu | Sikelo yaying'ono yochepetsera, kusinthasintha kwapang'ono pakugwiritsa ntchito, kukhazikika kwabwino pakupanga. |
Mkulu wamakina mphamvu | Modulus yabwino, magwiridwe antchito abwino, kulimba kwamphamvu kwambiri, kukakamiza kwamtundu wa loosetube ndikokwera kuposa zomwe zimafunikira. | |
Thermal katundu | Kutentha kwakukulu kosokoneza | Kaya pakulemedwa kwakukulu kapena kutsika, kupotoza kumakhala kwabwino kwambiri |
Hydrolytic katundu | Anti-hydrolysis | Kuchita kwakukulu kwa anti-hydrolysis makeoptical cable kukhala ndi moyo wautali kuposa zomwe zimafunikira. |
Mankhwala katundu | Chemical resistance | PBT imatha kulekerera kutentha kwachipinda cha polarity chemical reagentat.Ndipo PBT sigwirizana ndi kudzaza gel osakaniza.pa kutentha kwambiri komanso sachedwa kukokoloka. |

Kusungirako ndi zoyendera
Phukusi: Awiri phukusi njira, : 1. Iwo odzaza 900/1000KG pa thumba ndi akalowa mkati mwa zotayidwa zojambulazo zakuthupi, akalowa kunja kwa PE nsalu zakuthupi.2. Imadzaza 25KG pachikwama chilichonse chokhala ndi zolembera zamkati za aluminiyamu, chinsalu chakunja cha pepala la kraft.
Mayendedwe: Siziyenera kukhala pachimake ponyowa kapena chinyezi panthawi yamayendedwe, ndipo sungawume, ukhondo, wokwanira komanso wopanda kuipitsidwa.Kusungirako: Zimasungidwa m’nkhokwe yaukhondo, yozizira, yowuma komanso yolowera mpweya wabwino kutali ndi komwe kumayaka moto.Ngati mankhwalawa apezeka kuti akunyowa chifukwa chamvula kapena ndi chinyezi chambiri mumlengalenga, Atha kugwiritsidwa ntchito ola limodzi pambuyo pake ataumitsa kutentha kwa 120 ℃.

Kupambana kwaukadaulo wa sayansi ndiukadaulo
Pakalipano, fakitale ya Jiangyin ili ndi ma 8 ovomerezeka a PBT ndi ma bushings osinthika a polypropylene, ma 38 ovomerezeka a chitsanzo, ndipo adatenga nawo gawo pakupanga mfundo zamagulu a PBT.
Adapeza zinthu zitatu zotsimikizira zaukadaulo wapamwamba kwambiri.
Mu 2017, idakhazikitsa malo opangira kafukufuku ndi chitukuko cha zida za polima mogwirizana ndi Shanghai Jiao Tong University.
Mu Okutobala 2018, idadziwika ngati bizinesi yapamwamba kwambiri ndi Province la Jiangsu.
Wonjezerani chitukuko cha zinthu zatsopano, ndi kupanga kafukufuku wa zinthu wapafupi ndi chitukuko mgwirizano limagwirira ndi makampani odziwika chingwe kunyumba ndi kunja.
