PTFE tsis tas yuav lo rau iav fiber ntau. Yog tsis muaj kev kho deg kom zoo, PTFE txheej rau PTFE cov ntaub kub kub cov neeg ua hauj lwm nto - kev kho tshuaj siv rau fiberglass ntaub ua ntej txheej.
Cov neeg ua hauj lwm no - feem ntau organosilane coupling agents - ua raws li cov txuas hniav molecular, chemically bonding lub inorganic iav fiber rau cov organic PTFE. Kev xaiv ntawm tus neeg sawv cev, nws cov concentration, thiab kev kho cov txheej txheem hauv paus txiav txim siab tev lub zog, kub ua haujlwm, lub neej flex, thiab kev ua haujlwm dielectric.
Aokai PTFE tau ua kom zoo tshaj qhov chaw tiav chemistry thoob plaws ntau xyoo lawm. Phau ntawv qhia no piav qhia txog pawg neeg sawv cev tseem ceeb, lawv qhov cuam tshuam rau cov khoom tseem ceeb, thiab vim li cas kev kho kom zoo yog tsis sib tham rau cov ntaub PTFE zoo.
Pawg tseem ceeb ntawm Deg Finishing Agents
Ua ntej PTFE txheej, fiberglass ntaub feem ntau undergoes wax tshem tawm thiab ua kom nto. Cov tshuaj kho mob raug cais los ntawm cov tshuaj muaj pes tsawg leeg raws li hauv qab no:
Qeb
Yam khoom
Nta & Daim Ntawv Thov
Organosilane Coupling Agent (Feem ntau siv)
Amino silane (KH-550 / A-1100); Epoxy silane (KH-560 / A-187)
Condenses ntawm Si-OH nrog hydroxyl pawg ntawm iav fiber ntau; Organic functional pab pawg tsim tshuaj bonds los yog lub cev entanglement → molecular txuas hniav, drastic boosting txheej adhesion

Tsawg-molecular-yuag PTFE / FEP / PFA dispersion, resin primer blended nrog coupling tus neeg sawv cev
Cov ntaub ntawv ultra-thin transitional fluoropolymer txheej ntawm fiberglass los pab txhawb kev sib txuas ntawm topcoat tom ntej; drastic txo qhov kev pheej hmoo delamination
Aokai PTFE siv cov khoom sib xyaw ua ke ntawm epoxy silane thiab fluorinated coupling cov neeg ua haujlwm rau peb cov ntaub ntawv kub-kub PTFE. Cov qauv no tuaj yeem tiv taus 260 ° C txuas ntxiv kev pabcuam yam tsis muaj kev cuam tshuam ntawm lub ntsej muag - validated los ntawm 3,000-teev kev ntsuas kub kub.
Kev cuam tshuam rau Core Properties ntawm PTFE High-Temperature Cloth
Ua hauj lwm raws li qhov nruab nrab ntawm interfacial nruab nrab ntawm inorganic iav fiber ntau thiab organic fluoroplastic, kev kho tus neeg saib xyuas qib thiab kev ua tiav ua tiav tag nrho cov khoom tiav.
1. Adhesion Strength & Peel Durability

Kev cuam tshuam tseem ceeb: Peel lub zog yog qhov txiav txim siab rau lub neej qaug zog thiab delamination tsis kam.
2. Thaum tshav kub kub Resistance & Thermal Stability
High-temperature-resistant coupling agents (muaj benzene los yog heterocyclic qauv, xws li, tej yam epoxy & acyloxy silanes) tiv taus 260 ° C thiab instant peaks> 300 ° C - txuam PTFE cov kev pab cuam.
Cov pa organic additives thermally decompose ntawm siab kub → interfacial voids, daj discoloration, txheej spalling.
Daim ntawv thov kev cuam tshuam: Rau cov ntawv thov kub kub, xyuas kom tus neeg ua haujlwm tiav nws tus kheej yog thermally ruaj khov, tsis yog PTFE txheej.
Uniform silane hloov kho txhim kho PTFE emulsion kis thiab ntub dej ntawm fiber ntau nto → nruam compact txheej nrog tsawg pinholes thiab microcracks → tseem ceeb rau kev tawg voltage thiab rwb thaiv tsev muaj peev xwm.
Hygroscopic los yog ion-contaminated tshuaj kho mob ua rau dielectric poob. High-purity silane yog saws rau premium-qib PTFE daim ntaub kom txo impurity cuam tshuam.

Cov khoom tseem ceeb: Nto xov tus neeg sawv cev yog cov thev naus laus zis thev naus laus zis rau PTFE cov ntaub kub kub ntau lawm. Dominated los ntawm organosilane coupling agents, cov tshuaj no tsim molecular linkage ntawm inorganic-organic interface los daws PTFE qhov tsis zoo inherent adhesion rau fiberglass. Lawv hauv paus txiav txim siab tev lub zog, flex lifespan, tshav kub tsis kam, hluav taws xob rwb thaiv tsev, thiab tshuaj inertness.
Hauv cov ntsiab lus , tus neeg sawv cev nto thov rau fiberglass ntaub ua ntej PTFE txheej tsis yog ib qho me me nthuav dav - nws yog lub hauv paus ntawm PTFE high-temperature ntaub zoo. Organosilane coupling agents (amino, epoxy, fluorinated) tsim cov txuas txuas tseem ceeb ntawm cov iav fiber ntau thiab PTFE, boosting tev lub zog ntawm <2 N / cm rau 4-8 + N / cm. Kev kho kom zoo kuj tseem ua kom cov cua sov ua haujlwm (260 ° C +), txheej compactness, dielectric kev ua tau zoo, thiab tshuaj tsis kam.
Thaum xaiv PTFE daim ntaub rau daim ntaub ntawv thov, nug txog qhov chaw tiav chemistry - nws cuam tshuam ncaj qha rau kev pab cuam lub neej thiab kev ntseeg siab. Tsis txhob kho los yog kho tsis zoo substrates, uas yuav delaminate nyob rau hauv thermal thiab mechanical stress.
