PTFE high-temperature npuag (PTFE-coated fiberglass) muaj cov thermal poob siab zoo nyob rau hauv nws qhov kev ua haujlwm ntawm -70 ° C txog 260 ° C. Nws tuaj yeem tiv taus kub ceev ceev, piv txwv li, txav los ntawm -50 ° C lub freezer mus rau 260 ° C kub xovxwm. Cov qib hwm tseem muaj sia nyob tam sim ntawd txias los ntawm 260 ° C rau hauv dej 10 ° C. Txawm li cas los xij, kev poob siab ntawm cov khoom los ntawm qhov kub siab tshaj 300 ° C (ze PTFE's 327 ° C melting point) yuav ua rau tawg tam sim ntawd thiab delamination. Lub fiberglass substrate muab qhov ntev stability; PTFE txheej yog qhov txwv.

PTFE high-temperature npuag yog dav siv nyob rau hauv kev lag luam tshuaj rau xya daim ntaub ntawv tseem ceeb: flange gaskets thiab cov yeeb nkab hauv ob sab phlu (resists muaj zog acids / alkalis), reactor thiab tank linings (tiv thaiv hlau corrosion, yooj yim tu), lim hnab rau corrosive flue gas (txog 260 ° C), anti-corrosion expansion pob qij txha rau ducts, ducts, molding, thiab hluav taws xob / thermal rwb thaiv tsev qhwv. FDA thiab UL qib muaj.

PTFE high-temperature npuag (PTFE-coated fiberglass) muaj plaub qhov txiaj ntsig zoo raws li kev tiv thaiv corrosion hauv ob sab phlu: tshuaj inertness (resists aqua regia, muaj zog alkalis, cov kuab tshuaj), qhov kub ntau (-70 ° C txog 260 ° C tas mus li, 350 ° C ncov), qhov ntev stability (<0.5% non-staining), elongation thiab stains. Siv nyob rau hauv cov kav dej tshuaj, desulfurization yees, pickling tank, thiab khoom noj khoom haus/pharma. FDA qib muaj.

PTFE high-temperature npuag muaj 6 qhov zoo tshaj plaws raws li kev luam ntawv conveyor siv: tsis yog-stick nto (luam ntawv muab tshuaj txhuam thiab number case tso tawm kom huv), 260 ° C kub tsis kam (nqus kom qhuav), qhov ntev stability (<0.5% elongation, meej sau npe), tshuaj inertness (tiv corrosive pastes), tsis muaj kev sib txhuam (cov xim zoo li qub, kev ua haujlwm zoo li qub), thiab kev ua haujlwm zoo. Qhov zoo tshaj plaws rau kev tshuaj ntsuam luam ntawv, luam ntawv digital, thiab daim ntawv thov hloov hluav taws xob.

Anti-static PTFE high-temperature npuag combines cov tsis-stick, tshav kub-resistant (260 ° C), thiab chemically inert zog ntawm tus qauv PTFE nrog static-dissipative kev ua tau zoo. Cov ntawv thov tseem ceeb: kev tsim khoom siv hluav taws xob (PCB lamination, cov khoom siv tuav), PV module lamination (tiv thaiv ESD kev puas tsuaj rau lub hnub ci), cov khoom noj thiab tshuaj ua haujlwm (ESD-kev nyab xeeb ci liner), tshuaj nroj tsuag (tiv thaiv corrosion, anti-static ducting), thiab textile / luam ntawv industries. Surface resistance feem ntau 10⁶–10⁹ Ω.

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 yog ruaj khov mus txog 300 ° C, tab sis nyob rau hauv ib tug hluav taws kub nws decomposes thiab tso tawm cov pa phem heev: hydrogen fluoride (HF) (corrosive, pulmonary edema) thiab perfluoroisobutylene (PFIB) (tsis muaj xim, tsis muaj ntxhiab, ~ 10x ntau toxic tshaj phosgene), tsis muaj tshuaj tiv thaiv. Kuj tseem muaj cov pa roj carbon monoxide, PFOA residues, thiab kab dioxins. Cov qhov ncauj qhov ntswg ua pa tsis zoo; siv lub tshuab ua pa ntawm tus kheej (SCBA). Cov tsos mob yuav ncua.

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.
