PTFE high-temperature npuag muaj cov tshuaj tiv thaiv tshwj xeeb, tiv taus cov kua qaub, alkalis, cov kuab tshuaj organic, thiab corrosive gases. Tsab ntawv xov xwm no qhia txog nws cov tshuaj tiv thaiv, kev txwv (molten alkali hlau, muaj zog fluorinating cov neeg ua haujlwm), thiab cov ntsiab lus tseem ceeb xws li kub, concentration, thiab kev ntxhov siab.

PTFE impregnation tsis txwv rau fiberglass daim ntaub. Kab lus no qhia txog 7 lwm cov substrates - aramid, carbon fiber, PBI, ntxeem tau hlau, graphite, asbestos (phased tawm), thiab ceramic fillers - nrog lawv cov txheej txheem nta, zoo, kev txwv, thiab cov ntawv thov tseem ceeb.

Kab lus no piav qhia vim li cas cov ntaub ntawv tsis muaj alkali-dawb fiberglass yog qhov nyiam substrate rau PTFE high-temperature ntaub. Nws npog cov tshuaj sib txuas ntawm silane coupling cov neeg ua haujlwm thiab cov khoom siv lub cev tseem ceeb xws li thermal stability, seem stability, thiab corrosion kuj - kom ntseeg tau tias kev ua haujlwm ntev nyob rau hauv ib puag ncig hnyav.
