PTFE high-temperature fabric siamna kawngah hian drying hi thil pawimawh tak a ni. A chhiatna tlangpui chu: cracking (a vawt rang lutuk, a chunglam vun), coating migration (particles te chu lei chung lamah an kal a, a chhung lam bond chak lo), pinholes/blisters (trapped air or steam), white spots leh chalking (surfactant migration emaw incomplete fusion), yellowing/coking (additives a lum lutuk), delamination (shrinkage stress exceeds adhesion), orange peel (leveling tha lo), warpage (uneven shrinkage), surface dry mahse interior wet (skinning traps moisture), leh a sir thick (coffee-ring effect) te a awm bawk. Solution-ah hian controlled drying profile, ventilation dik tak, leh substrate pretreatment te a tel a ni.

PTFE high-temperature fabric hi chemical industry-ah hmanraw pawimawh pasarih atan hman a ni nasa hle a, chungte chu flange gasket leh pipe linings (acid/alkali chak tak a do thei), reactor leh tank linings (metal corrosion a veng a, tihfai awlsam), corrosive flue gas dahna tur filter bag (260°C thleng), ducts tan anti-corrosion expansion joint, anti-adhesion welding pads, composite molding atana release cloth, leh electrical/thermal insulation wraps te a awm bawk. FDA leh UL grade a awm bawk.

PTFE coating hmaa fiberglass fabric-a surface finishing agents hman hi final PTFE high-temperature cloth performance atan a pawimawh hle. Organosilane coupling agents hian inorganic glass fiber leh organic PTFE inkarah molecular bridge a siam a, hei hian peel strength <2 N/cm atanga 4-8+ N/cm thlengin a tipung a ni. Treatment dik tak hian heat resistance (260°C+), dielectric performance, leh chemical resistance a tichak bawk. Fabric enkawl loh hian delamination, bubbling, leh service life tawi a thlen thin.
