High-strength PTFE high-temperature npuag yog ib tug composite ntawm high-tenacity fiberglass thiab PTFE txheej. Cov ntawv thov tseem ceeb nthuav dav kev lag luam (khoom noj khoom haus, textile drying, PCB thauj), vuam tiv thaiv (tshav kub-sealer npog, spatter shields), demolding thiab kub xovxwm tsim (rubber molding, PV lamination), hluav taws xob rwb thaiv tsev (motor slot liners, cable wraps), architectural membranes (chaw ntau ntau lub ru tsev, 30+ corrosive lub neej), aerospace (pam cua sov), thiab kev siv tshwj xeeb (laser txiav, 3D luam ntawv).

Ua ntej ziab ntawm fiberglass ntaub yog qhov tseem ceeb rau PTFE txheej tom ntej, resin impregnation, lossis lamination. Peb txoj kev kho tseem ceeb: tshem tawm cov dej noo ntawm 105-120 ° C (10-30 min nyob ntawm qhov hnyav), dewaxing / thermal tu ntawm 300-450 ° C (LOI <0.1%, zam> 500 ° C), thiab preheating ntawm 60-100 ° C ua ntej txheej. Tswj qhov kub ntawm qhov sib xws (± 5 ° C), yuam kom dehumidification, thiab tiv thaiv cov ntaub qhwv silane hauv qab 110 ° C. Khaws cov ntaub qhuav hauv cov hnab ntim khoom lossis chav qhuav (<30 ° C, <40% RH).

PTFE high-temperature npuag kev pab cuam lub neej txawv heev los ntawm daim ntawv thov. Cov tshuaj tiv thaiv corrosion tuaj yeem siv tau 3+ xyoo (4x ntev dua li roj hmab). Cov tais ci zaub mov lub hli tas los nrog me ntsis degradation. Cov khoom siv conveyor siv los ntawm kev sib txhuam. PV lamination (150 ° C, EVA tiv tauj) muaj lub neej nruab nrab. Cov ntawv thov kev sib txhuam hnyav (abrasive discs) muaj lub neej luv. Cov yam tseem ceeb: tswj qhov kub thiab txias (nyob twj ywm ≤260 ° C), tsis txhob muaj cov creases ntse, ntxuav tsis tu ncua, thiab hloov raws sij hawm thaum blistered los yog yellowed.

PTFE high-temperature npuag (PTFE-coated fiberglass) kav ntev tshaj plaws thaum khaws cia hauv qab 260 ° C, kom deb ntawm cov creases ntse, thiab ntxuav nrog cov cuab yeej mos. Cov yam tseem ceeb ntawm lub neej txwv: thermal degradation saum 260 ° C, thermal poob siab los ntawm cua sov / txias, txhua yam qaug zog los ntawm dabtsi yog khoov thiab nro, tshuaj tua kab mob los ntawm molten alkali hlau los yog muaj zog oxidizers, puas los ntawm hlau scrapers thaum ntxuav, thiab UV raug rau sab nraum zoov siv. Qhov zoo ntawm txheej thiab substrate kuj tseem ceeb.

PTFE high-temperature npuag (PTFE-coated fiberglass) yog zoo tagnrho rau microwave cua sov vim hais tias nws kis microwaves tsis absorbing zog, resists 260 ° C, thiab muaj ib tug uas tsis yog-stick nto. Cov ntawv thov suav nrog microwave ci mats, muaj cov tshuab ziab khaub ncaws conveyor siv, reactor linings rau tshuaj digestion, thiab microwave paj kws hnab liners. FDA qib muaj rau kev sib cuag zaub mov.

PTFE high-temperature npuag (PTFE-coated fiberglass) tsis zoo flex kuj vim hais tias cov 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 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 nto 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 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 ua tau zoo.

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.
