PTFE high-temperature daim ntaub yog tsim los ntawm ib leeg-dip impregnation (ib qho dhau: ceev, tsis tshua muaj nqi, txheej nyias, ntxhib nto nrog pinholes) los yog ntau-dip impregnation (2-3+ dhau: du, ntom, tsis muaj pinhole-dawb txheej, PTFE cov ntsiab lus 50-70%, kev ua tau zoo dua, tus nqi siab dua). Ib leeg-dip suits qib qis gaskets, ib ntus mats, thiab cov ntaub ntawv breathable. Multi-dip yog yuav tsum tau rau cov zaub mov-qib ntawv ci, tsis-stick conveyor siv, high-frequency Circuit Court substrates, tshuaj liners, thiab architectural daim nyias nyias.

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).

Raw khoom purity yog lub hauv paus ntawm PTFE high-temperature npuag kev ua tau zoo. High-purity PTFE emulsion (tsis muaj hlau ions, tsis tshua muaj-molecular-yuag residues) ua kom cov cua sov tsis kam (tsis yellowing mus txog 260 ° C), ruaj khov tsis-stick, thiab siab dielectric zog. Rau fiberglass, alkali-dawb E-iav (Na₂O <0.8%) tswj lub zog thiab rwb thaiv tsev ntawm qhov kub thiab txias; nruab nrab / siab-alkali iav ua rau degradation. Ua kom tiav kev tshem tawm ntawm cov xov paj sizing tiv thaiv carbonization thiab delamination. Purity ncaj qha cuam tshuam rau lub neej kev pabcuam, kev ua raws li qib zaub mov, thiab kev ntseeg tau ntawm hluav taws xob.

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 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 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.
