PTFE high-temperature npuag muaj ib coefficient ntawm thermal expansion (CTE) ntawm 30-60 ppm / ° C (warp / weft) - siab tshaj fiberglass ib leeg tab sis deb qis dua ntshiab PTFE (100-200 ppm / ° C). PTFE tau hloov pauv sai sai (1-2%) ntawm 19 ° C thiab 30 ° C theem hloov. Txhawm rau kom tsis txhob buckling, tearing, thiab delamination: tsim clearances dawb expansion, tsis txhob tensioning los ntawm theem hloov kub, siv tsis siv neeg tensioners ntawm conveyor siv, thiab siv anti-buckling overlap tsim. Kev tshuaj xyuas tsis tu ncua rau cov dej txias yog qhov tseem ceeb.

PTFE high-temperature fabric baking mats muaj plaub qhov txiaj ntsig tseem ceeb: kev ua haujlwm tsis zoo (tsis muaj roj lossis hmoov nplej, cov khoom noj qab zib tso tawm kom huv), qhov kub ntau (-70 ° C txog 260 ° C, muaj kev nyab xeeb rau qhov cub rau lub freezer), rov siv dua (txhiab ntau lub voj voog, yooj yim los ntxuav), thiab txawm tias kub kub (tiv thaiv kub hnyiab, sib npaug xim av). Khoom noj khoom haus-qib FDA raws, lawv outlast daim ntawv parchment thiab outperform silicone mats nrog zoo dua tshav kub hloov thiab finer nto zoo nkauj.

PTFE high-temperature npuag yog qhov tseem ceeb hauv kev lag luam tsoos tsho interlining. Cov ntawv thov tseem ceeb: seamless endless conveyor siv rau cov tshuab fusing tas li (tiv thaiv kub yaj nplaum nplaum, tsis muaj wrinkle conveying), non-stick cover thiab padding daim ntaub rau tiaj tshav kub presses (tiv thaiv platens los ntawm nplaum kab mob), conveyor siv rau dot paste / hmoov txheej kab (txheej txheem dotsing ntswj thaum lub sij hawm kev sib cuag nrog hlau) qauv nias. Thickness ranges ntawm 0.13mm (lub teeb padding) mus rau 0.55mm (hnyav-duty conveyor txoj siv sia).

Fiberglass npuag thermal shrinkage yog thawj qhov ua rau PTFE daim kab xev seem tsis ruaj khov. Ntawm PTFE sintering kub (360-400 ° C), residual weaving stress yog tso tawm. Yog tias tsis muaj kev txwv, cov ntaub shrinks; Yog tias txwv tsis pub, kev ntxhov siab latent raug kaw, ua rau tom qab shrinkage thaum lub sij hawm kho (150-200 ° C) thiab siv cua sov kawg. Kev daws: siv pre-heat-set fiberglass nrog <0.5% shrinkage ntawm 400 ° C, tshem tawm cov residual kev nyuaj siab ua ntej txheej.

PTFE high-temperature npuag (PTFE-coated fiberglass) muaj cov tshuaj tiv thaiv tshwj xeeb, tiv taus cov kua qaub (xws li aqua regia), muaj zog alkalis (hauv chav sov), cov kuab tshuaj organic, thiab cov tshuaj oxidizing. Kev zam: molten alkali hlau thiab high-temperature halogen compounds tua PTFE. Txheej kev puas tsuaj nthuav tawm fiberglass rau hydrofluoric acid thiab kub concentrated alkalis. Qhov kub siab tshaj 260 ° C txo qhov tsis kam. Rau feem ntau cov cheeb tsam tshuaj, PTFE ntaub tseem ruaj khov thiab txhim khu kev qha.

Aokai PTFE tau nthuav tawm nws cov khoom lag luam tag nrho ntawm APFE Shanghai 2026 (Lub Rooj Muag Khoom 6T602, Hall 6). Cov khoom tshwj xeeb muaj xws li fiberglass-reinforced PTFE tapes, ntshiab PTFE films, anti-static qib, thiab high-temperature conveyor siv - npog cov zaub mov, PV lamination, lithium roj teeb, electronics, thiab ntim. Lub exhibition pib mus txog rau lub rau hli ntuj 26. Tag nrho cov khoom txhawb kev cai specifications.

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).

Kev ziab yog ib kauj ruam tseem ceeb hauv PTFE high-temperature fabric production. Cov teeb meem tshwm sim muaj xws li: tawg (hnyav qhuav, tawv nqaij tawv), txheej tsiv teb tsaws (cov khoom txav mus rau saum npoo, tsis muaj zog sab hauv daim ntawv cog lus), pinholes / hlwv (cua hauv huab cua lossis chav dej), cov pob dawb thiab chalking (surfactant migration lossis tsis tiav fusion), yellowing / coking (overheating ntawm additives), delamination (shrinkage theem), ntau tshaj qhov kev nyuab siab. shrinkage), nto qhuav tab sis sab hauv ntub dej (skinning ntxiab ya raws), thiab tuab npoo (cov nyhuv kas fes). Cov kev daws teeb meem suav nrog kev tswj kom qhuav profiles, kom qhov cua zoo, thiab substrate pretreatment.

PTFE emulsion impregnation ntawm fiberglass ntaub yuav tsum muaj ntau yam auxiliaries kom ua tiav cov txheej txheej, muaj zog adhesion, thiab qhov chaw tsis raug. Cov additives tseem ceeb muaj xws li: cov khoom ntub dej (txo qhov nro, txhim kho kev nkag mus), thickeners (tswj viscosity thiab txheej hnyav), pH regulators (stabilize emulsion ntawm pH 9-10), silane coupling agents (txhim adhesion rau iav), film-forming aids (PFA / FEP), kev ua haujlwm tsis zoo (PFA / FEP), kev ua haujlwm tsis zoo (tiv thaiv pinholes), thiab humectants (qhib kom qhuav). Kev xaiv nyob ntawm substrate thiab kev ua haujlwm yuav tsum tau ua.

Expanded fiberglass npuag (bulked yarn fabric) txawv hauv paus los ntawm cov pa fiberglass npuag hauv cov qauv xov paj. Los ntawm kev kho cua dav hlau siab, cov iav filaments txuas ntxiv raug sib cais, crimped, thiab fluffed rau hauv voluminous, paj zoo li xov paj. Qhov no tsim cov ntaub thicker, softer nrog superior thermal rwb thaiv tsev (cua khaubncaws sab nraud povtseg), zoo conformability, ntau pom efficiency, thiab txhim kho kua muag / flex kuj - ntawm tus nqi ntawm lub zog tensile zog me ntsis. Siv rau qhov kub kub gaskets, yeeb nkab qhwv, lim hnab, thiab qhov cub seals.
