Kev ziab yog ib kauj ruam tseem ceeb hauv PTFE high-temperature fabric production. Cov teeb meem tshwm sim muaj xws li: tawg (hnyav qhuav, tawv nqaij tawv), txheej tsiv teb tsaws (cov khoom txav mus rau saum npoo, tsis muaj zog sab hauv daim ntawv cog lus), pinholes / hlwv (cua hauv huab cua lossis chav dej), cov pob dawb thiab chalking (surfactant migration lossis tsis tiav fusion), yellowing / coking (overheating ntawm additives), delamination (shrinkage theem), ntau tshaj qhov kev nyuab siab. shrinkage), nto qhuav tab sis sab hauv ntub dej (skinning ntxiab ya raws), thiab tuab npoo (cov nyhuv kas fes). Cov kev daws teeb meem suav nrog kev tswj kom qhuav profiles, kom qhov cua zoo, thiab substrate pretreatment.

PTFE high-temperature npuag yog dav siv nyob rau hauv kev lag luam tshuaj rau xya daim ntaub ntawv tseem ceeb: flange gaskets thiab cov yeeb nkab hauv ob sab phlu (resists muaj zog acids / alkalis), reactor thiab tank linings (tiv thaiv hlau corrosion, yooj yim tu), lim hnab rau corrosive flue gas (txog 260 ° C), anti-corrosion expansion pob qij txha rau ducts, ducts, molding, thiab hluav taws xob / thermal rwb thaiv tsev qhwv. FDA thiab UL qib muaj.

Nto xov cov neeg ua hauj lwm siv rau fiberglass ntaub ua ntej PTFE txheej yog ib qho tseem ceeb rau qhov kawg PTFE high-temperature daim ntaub. Organosilane coupling cov neeg ua haujlwm tsim cov txuas txuas ntawm cov iav fiber ntau thiab cov organic PTFE, txhawb nqa lub zog tev ntawm <2 N / cm rau 4-8 + N / cm. Kev kho kom zoo kuj tseem txhim kho cov cua sov (260 ° C +), dielectric kev ua tau zoo, thiab tshuaj tiv thaiv. Cov ntaub tsis kho ua rau delamination, bubbling, thiab lub neej ua haujlwm luv.
