PTFE high-temperature npuag (PTFE-coated fiberglass) tsis zoo flex tsis kam vim fiberglass substrate yog inherently brittle. Cov ntaub nyias nyias (0.08mm) muaj sia nyob ntau pua mus rau txhiab folds; hnyav qib (> 0.25mm) tawg tom qab kaum ob. Satin weave outperforms dawb weave. Rau kev sib txuas txuas ntxiv txuas ntxiv, xav txog cov khoom PTFE zaj duab xis lossis aramid-raws li ntaub hloov.

PTFE high-temperature daim kab xev ua haujlwm rau PV kev lag luam hauv ob lub luag haujlwm sib txawv: cov txheej txheem siv tau (tiv thaiv EVA overflow adhesion ntawm laminators, solder mask) thiab lub neej ntev rwb thaiv tsev (busbar qhwv, junction box fixation). Rau kev siv mus tas li, cov ntaub nplaum yuav tsum dhau IEC 61215: 1000-2000h damp cua sov, UV, thermal cycling (-40 ° C txog + 85 ° C), nrog silicone PSA thiab shrinkage <1%.

PTFE high-temperature npuag (PTFE-coated fiberglass) yog dav siv nyob rau hauv textile printing thiab dyeing rau tshav kub hloov luam ntawv siv (180-230 ° C), tshuaj ntsuam luam ntawv lub rooj npog, ziab mesh siv, fusing tshuab siv, thiab cov menyuam wrapping. Nws tsis yog-stick deg tiv thaiv tus number case / nplaum residue, txo kev tu ncua sij hawm thiab txhim kho cov ntaub zoo. Seamless txoj siv sia uas tsis muaj qhov kawg ua rau kev tsim khoom tas mus li.

PTFE high-temperature daim kab xev siv rau tshav kub-sealing riam thiab sealing strips muab plaub lub ntsiab tseem ceeb: tiv thaiv molten yas adhesion (tso tseg downtime), tiv thaiv kim sealing tuag, homogenizes tshav kub / siab rau zoo seals, thiab txo cov zaj duab xis kev sib txhuam. Fiberglass-backed daim kab xev (0.13-0.25 mm) nrog silicone PSA (≥260 ° C) yog pom zoo. Anti-static dub daim kab xev rau high-speed kab.

PTFE high-temperature npuag (PTFE-coated fiberglass) yog cov khoom siv lim dej zoo tshaj plaws rau cov xwm txheej huab cua: tshem tawm cov pa roj plua plav (cement, khib nyiab incineration, thee boilers mus txog 260 ° C), corrosive kua pom (acids, alkalis, roj), zaub mov / tshuaj sterile filtration, thiab lim. Non-stick nto tiv thaiv plua plav caking thiab tso cai rau kev ntxuav yooj yim. Membrane-laminated qib ua tiav cov pa hluav taws xob tsawg.

PTFE high-temperature ntaub tuav zoo heev hluav taws xob rwb thaiv tsev los ntawm -180 ° C mus rau 260 ° C: ntim resistivity > 10¹³ Ω·cm ntawm 200 ° C, dielectric qhov ruaj khov ntawm 2.0-2.1. Tshaj 260 ° C, PTFE softens, decomposes saum 327 ° C, poob rwb thaiv tsev mus tas li. Hauv qab 0 ° C, rwb thaiv tsev zoo dua, tab sis txheej yuav nkig. Nyob rau hauv 260 ° C rau kev txhim khu kev qha.

Cov dej vapor barrier cov cuab yeej ntawm PTFE nplaum daim kab xev yog txiav txim siab feem ntau los ntawm txheej tsis xws luag (micropores, microcracks, fiber wicking) es tsis yog PTFE's intrinsic hydrophobicity. Pure PTFE zaj duab xis tsuas yog nruab nrab WVTR. Multi-txheej txheej thiab lamellar fillers (mica, iav flakes) tsim cov nyhuv labyrinth, drastic txo vapor kis tau tus mob. Rau high-humidity sealing, qhia densified txheej.

PTFE high-temperature npuag (PTFE-coated fiberglass) yog zoo tagnrho rau cov khoom noj khoom haus conveyor siv vim nws 260 ° C tshav kub tsis kam, -70 ° C txias yooj, tsis-stick nto, thiab FDA ua raws. Daim ntawv thov tseem ceeb: bakery ncu (biscuits, qhob cij, pizza), kib zaub mov conveyors, khoom qab zib txias kab, freezing tunnels, tshav kub sealers, thiab cov menyuam qhwv. Txo cov khib nyiab thiab ntxuav lub sijhawm.

Creep kuj ntawm PTFE high-temperature adhesive daim kab xev nyob rau hauv lub sij hawm ntev load (tshwj xeeb tshaj yog nyob rau ntawm 200-260 ° C) yog txiav txim los ntawm ob yam: silicone PSA crosslink ceev (siab dua crosslinking tiv thaiv ntws) thiab substrate hom (fiberglass-reinforced PTFE resists txias creeps; ntshiab PTFE zaj duab xis creeps). Uncrosslinked nplaum ua tsis tau sai thaum kub kub. Thicker nplaum txheej ua rau muaj kev pheej hmoo nkag.

Rau PTFE high-temperature daim kab xev siv nyob rau hauv abrasive zawv zawg kev sib txhuam daim ntaub ntawv, standard non-stick thiab tshav kub kuj tsis txaus. Cov txheej txheem xaiv tseem ceeb: Taber abrasion poob (<15 mg / 1000 cycles), hloov kho PTFE txheej (carbon / graphite / MoS₂), PV txwv cov ntaub ntawv, lub zog substrate (≥200 N / cm), thiab mating nto roughness (Ra 0.2-0.4 μm). Kev tiv thaiv ntug zoo thiab kev sib txuas tag nrho yog qhov tseem ceeb rau lub neej ntev.
