Khoom Description
PI lub tes tsho
Cov Hluav Taws Xob Hluav Taws Xob Polyimide PI Lub Tes Tsho yog woven los ntawm siab -kev ua tau zoo polyimide fiber ntau-ib qho tshuaj tsw qab heterocyclic polymer tsim los ntawm qhov kawg ntawm cov khoom siv thermal- tiv taus.
Tsis zoo li cov ntaub kho mob uas tsis muaj kev tiv thaiv tom qab ntxuav, los yog aramids uas char thiab tsis muaj zog, cov polyimide fiber ntau no yog qhov tsis yog -combustible. Nrog rau Limiting Oxygen Index (LOI) ntau tshaj 38%, nws tsis tuaj yeem txhawb nqa kev sib txuas hauv huab cua (21% oxygen). Nws tsis yaj. Nws tsis drip molten khib nyiab. Thaum qhov kub thiab txias, nws tsuas yog carbonizes - tuav cov qauv kev ncaj ncees thaum tiv thaiv cov khoom tseem ceeb hauv qab.
Lub tes tsho tsim ua ib qho seamless tubular barrier uas swb hla cables, hoses, kav dej, thiab khoom siv, muab 260-300℃nruam tiv thaiv thermal nrog excursions mus rau 500℃+. pa luam yeeb emission tsuas yog 1/200 ntawm aviation qauv-hloov txo asphyxiation txaus ntshai nyob rau hauv ib puag ncig. Los ntawm cov chaw tsim hluav taws xob rau cov khoom siv hluav taws xob hluav taws xob, qhov no yog lub tes tsho uas ua haujlwm thaum tsis ua haujlwm tsis yog qhov kev xaiv.
Cov yam ntxwv tseem ceeb
