Thaum xaiv PTFE high-temperature ntaub warp thiab weft ntom ntawm fiberglass substrate.
Qhov ceev txhais tau hais tias cov xov paj nruj npaum li cas tau ntim. Nws cuam tshuam rau txhua yam - tensile lub zog, tsim kua muag tsis kam, txheej adhesion, yooj, thiab nto smoothness. Too dense, and the cloth becomes stiff with poor tear strength. xoob dhau lawm, thiab pinholes yuav tshwm sim nrog qhov tsis muaj zog ntawm qhov ruaj khov.
Aokai PTFE tau ua kom zoo dua fiberglass ntom hla ntau txhiab tus khiav haujlwm. Phau ntawv qhia no piav qhia txog qhov ntom ntom cuam tshuam rau cov khoom tseem ceeb thiab pab koj xaiv qhov sib npaug rau koj daim ntawv thov.
Mechanical Strength & Dimensional Stability
1. Lub zog tensile
Qib Ceev
Tensile zog
Mechanism
Qhov ceev dua
Feem ntau siab dua
Ntau cov xov paj sib faib load rau ib chav tsev dav
Siab heev
Tej zaum toj siab los yog txo
Intensified yarn crimp txo qis siv fiber ntau; ntaub stiffens
Lus Cim: Rau cov ntawv thov uas xav tau lub zog tensile siab tshaj plaws (piv txwv li, dav conveyor siv nyob rau hauv siab nro), tsom rau nruab nrab-rau-siab ceev. But avoid extreme density, which causes premature fatigue under dynamic loads.
2. Tear Strength – Qhov Inverted U-Curve
Lub zog tsim kua muag yog qhov qhia tau zoo tshaj plaws cuam tshuam los ntawm qhov ntom ntom. Tom qab PTFE txheej, polymer resin locks woven yarns nyob rau hauv qhov chaw. Txoj kev sib raug zoo ua raws li qhov hloov pauv U-shaped nkhaus :
Qib Ceev
Tear Strength
Mechanism
Tsawg ceev
pluag
Qhov sib txawv ntawm cov xov paj loj ua rau cov xov paj tawg ua ntu zus; yarns tsis ua pawg
Qhov ntom ntom
Qhov zoo tshaj plaws (peak)
Cov xov paj me ntsis swb thiab sib sau ua ke hauv qab kev ntxhov siab los sib qhia quab yuam
Tshaj-siab ceev
Tsis zoo (txo qis)
Cov xov paj tag nrho immobilized los ntawm txheej + nruj weave; kev nyuaj siab concentrates rau ib tug neeg yarns → brittle rupture
Key takeaway: Maximum tear strength is achieved at moderate density , not highest density. Qhov no feem ntau yog counterintuitive.
Aokai PTFE muaj fiberglass substrates nrog kev tswj ceev ceev. Rau cov ntaub ntawv tsim kua muag tseem ceeb (xws li, txoj siv sia conveyor ntawm cov menyuam conveyors nrog nquag nres), peb pom zoo kom muaj qhov ntom ntom ntom (feem ntau 18-20 kawg / cm) kom ua kom lub kua muag ua haujlwm siab.
Cov yam ntxwv ntom ntom
Dimensional Stability
nyhuv
Balanced warp / weft ceev
Zoo heev
Synchronizes thermal shrinkage thiab kev ntxhov siab hauv ob qho tib si; tiv thaiv warping ntawm kub
Qhov sib txawv loj loj
pluag
Inconsistent thermal shrinkage → hnyav ntaub distortion nyob rau hauv tshav kub
Compact high-density
Zoo heev
Substrate txwv cov xov paj contraction
Kev pom zoo: Rau cov ntawv thov kub uas xav tau qhov tseeb qhov tseeb (piv txwv li, cov khoom siv hluav taws xob sib khi, cov ntaub ntawv laminating), xaiv qhov sib npaug, nruab nrab-rau-siab ceev substrates.
Txheej Penetration, Adhesion & Surface yam ntxwv
1. Permeability & Mechanical Anchoring Force
Qib Ceev
PTFE nkag mus
Txheej Adhesion
Tsawg-density
Kev nkag mus tob - emulsion ntws los ntawm cov pores loj
Cov ntaub ntawv 'rivet-like' mechanical interlock → kev sib txuas zoo heev
High-density
Hindered - resin tawm tsam kom nkag mus rau fiber ntau pob
Kev pheej hmoo ntawm 'nto-coated tsis tau inner-dry' qauv → pluag tev tsis kam
Kev lag luam tawm: Tsawg-density yuav tsum tau ntau txheej dhau los ua kom qhib meshes ( txwv tsis pub cov pinholes tawm ). High-density xav tau optimized dipping tsis los xyuas kom meej tag nrho cov nkag.
Qib Ceev
Nto tom qab txheej
Zoo tshaj rau
High-density
Fine woven kev ntxhib los mos, du tiav, premium non-stick, yooj yim tu
High-standard demolding daim ntaub ntawv (xws li, composite molding, zaub mov tso)
Tsawg-density
Distinct weave indentations tseem nyob
Conveyor siv nyob qhov twg textured nto yuav txo tau qhov chaw sib cuag, tso pa tawm los, los yog tiv thaiv workpiece slipping
3. Nrog Voltage & Pinhole Ratio
Denser puag daim ntaub muaj finer, ntau cov pores, yuav tsum tau thinner txheej kom ua tiav pinhole-dawb nto - kom ntseeg tau tias txhim khu kev qha dielectric zog.
Daim ntawv thov kev cuam tshuam: Rau kev siv hluav taws xob rwb thaiv tsev, cov khoom siv hluav taws xob siab yog nyiam.
Flexibility & Dynamic Fatigue Resistance
Qib Ceev
Yooj yim
Flex Fatigue Lub Neej
Zoo tshaj rau
Tsawg warp / weft ceev
Zoo heev - yarns txav mus los ntawm cov ntsiab lus interlacing
Ntev
Nrawm qhwv ib ncig ntawm me me-inch rollers; kev cai demolding wrapping rau irregular Cheebtsam
High-density
Rig thiab tawv
Luv luv
Daim ntawv thov zoo li qub lossis qis-flex
Tsis ua hauj lwm mechanism rau high-density nyob rau hauv flexing: Rov ua dua dabtsi yog khoov ua rau khaus kev sib txhuam thiab extrusion ntawm cov xov paj crossover cov ntsiab lus, ua rau txheej txheej tawg thiab lub hauv paus ntaub puas.
Kev pom zoo: Rau cov khoom ua hauj lwm nyob rau hauv kev nruam high-speed flexing (xws li, conveyor siv rau me me pulleys, dynamic seals), nruab nrab los yog tsawg ntom yog nyiam.

Golden txoj cai: Tsis txhob dig muag mus nrhiav qhov siab tshaj plaws. Optimal ntom tso cai rau PTFE nkag mus txaus thaum ntsuas lub kua muag tsis kam, yoog raws, thiab qhov tseeb. Rau feem ntau cov hom phiaj kev lag luam, qhov nruab nrab ntom (18-22 kawg / cm) muaj qhov ua tau zoo tshaj plaws nyob ib puag ncig.
Hauv cov ntsiab lus , warp thiab weft ceev ntawm fiberglass ntaub yog ib qho tseem ceeb tab sis feem ntau overlooked parameter rau PTFE high-temperature ntaub. Higher density increases tensile strength, surface smoothness, and dielectric performance, but reduces tear strength (after an optimal peak), flexibility, and coating penetration. Qhov qis dua txhim kho qhov yooj yim, ua rau qaug zog lub neej, thiab txheej txheej adhesion, tab sis tej zaum yuav tawm pinholes thiab rougher nto tiav.
Qhov tseem ceeb yog qhov sib npaug. Rau kev tsim kua muag-tseem ceeb thiab kev siv zog, xaiv qhov ntom ntom (18-22 kawg / cm). Rau ultra-smooth uas tsis yog-stick thiab hluav taws xob rwb thaiv tsev, siab ceev yuav raug tsim nyog. Rau siab tshaj plaws adhesion thiab dabtsi yog khoov endurance, low-to-moderate ntom ua haujlwm zoo tshaj plaws.
