PTFE high-temperature daim ntaub yog tsim los ntawm ib leeg-dip impregnation (ib qho dhau: ceev, tsis tshua muaj nqi, nyias txheej, 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 ci nplooj ntawv, tsis yog-stick conveyor siv, high-frequency Circuit Court substrates, tshuaj liners, thiab architectural daim nyias nyias.

PTFE-coated fiberglass ntaub sintering yuav tsum tau tuav lub sij hawm ntawm 370-400 ° C. Nruam rauv: 30-90s (nyias) mus rau 3-5+ min (thick). Batch furnaces: 5-15 feeb. Under-sintering ua rau opaque, ntxhib txheej uas tev; over-sintering ua rau yellowing, brittleness, thiab tshuaj fluoride gas tso tawm. Cov txheej txheem optimization: siv cov ntsuas kub ntawm lub cub tawg, ua qhov kev tshuaj xyuas qhov muag (semi-pob tshab, hloov tau), thiab ua cov ntawv rub tawm. Nco ntsoov xyuas kom tag nrho-thickness kub uniformity.

PTFE high-temperature npuag yuav tsum tau ceev faj tuav kom muaj kev nyab xeeb thiab siv tau ntev. Cov lus ceeb toom tseem ceeb: tsis txhob siab tshaj 260 ° C (siab dua 320 ° C tso pa tawm cov pa phem), tsis txhob muaj cov pa phem (ntxuav txheej, nthuav tawm fiberglass), tsis muaj kev ntxuav (steel wool puas tsis-stick nto), khaws cia thermal expansion clearance (tiv thaiv tearing), thiab hloov thaum blistered los yog tev. Khaws dov, kom deb ntawm UV. Hnav cov hnab looj tes tiv thaiv tshav kub thaum tuav.

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), kev tiv thaiv vuam (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 tsev, 30+ xyoo corrosive lub neej), aerospace (pam cua sov), thiab kev siv tshwj xeeb (laser txiav, 3D luam ntawv).

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 lom neeg 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 qhov zoo tagnrho rau microwave cua sov vim tias nws xa cov microwaves tsis muaj zog, tiv taus 260 ° C, thiab muaj qhov tsis zoo. Cov ntawv thov suav nrog microwave ci mats, muaj cov tshuab ziab khaub ncaws conveyor siv, reactor linings rau kev zom cov tshuaj lom neeg, thiab microwave paj kws hnab liner. 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 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 qhwv. 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 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 / kws tshuaj sterile lim, 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.
