Ki jan kouch PTFE la kole ak substra twal la vèr nan twal Tflon wo-tanperati?

PTFE (polytetrafluoroethylene) gen yon enèji sifas ekstrèmman ba epi li rekonèt kòm yon materyèl 'ki pa baton'. othmanufacturer–JiangsuAokaiNewMaterialTechnologyCo.,Ltd.,thebondingbetweenthetwoistypicallyachievedthroughphysicalanchoringandmechanicalinterlocking,complementedbychemicalprimertreatmentorhot-meltadhhesioncompositeeffects.

Metòd espesifik yo pou kole twal teflon ki gen tanperati wo sitou gen ladann sa ki annapre yo:

1.MechanicalInterlocking (FizikBonding) Sa a se apwòch ki pi fondamantal. Twal fib vè pwòp tèt li se yon tekstil pore.Lè emulsyon PTFE oswa pèsèyman anpreye oswa kouvri sou twal fib vè, PTFE antre nan twou vid yo ak pwen entèseksyon ant fib yo. Entering (apeprè 360–400 ° C), patikil PTFE yo fonn nan yon fim kontinyèl, byen kenbe fib yo tankou yon inonbrabl 'kwòk ank'.

2.SilaneCouplingAgentPretreatment(ChemicalBridging)

Sa a se prèske pwosesis debaz pou tout twal PTFE fibglass ki gen bon jan kalite.

Rezilta PTFErekouvwi dirèkteman nan yon move adezyon apre entèrnman an, pou premye dedye anjeneral aplike an premye nan twal fib vè.

Adhesiveresins: tankou poliamid-imid (PAI), polyphenylenesulfide (PPS), polyethersulfone (PES), oswa polyetheretherketone (PEEK), ki gen bon mouye ak adezyon solid ak fib vè, epi ki ka reziste pwosesis entèrasyon PTFE ki vin apre tanperati a.

PTFEmicropowder: Pou asire ke premye ak final PTFE pou jwè yo kapab fusion ansanm.

4.Hot-MeltAdhesiveFilmLamination(LaminationMethod) Metòd sa a, ki anplwayeJiangsuAokaiNewMaterialTechnologyCo.,Ltd.,itilize pou lye fim PTFE ki te pre-fòme,epè ak twal fib vè. ately10⊃1;⁰–10⊃1;⊃2;Pa·s), li difisil ap koule sèt lè chofe anlè pwen fizyon li, kidonk lyezon dirèk cho-près la pa posib. FEP (fluorinatedethylenepropylene) oswa PFA (perfluoroalkoxy) fim ,ki gen plis pwen fizyon pase PTFE (apeprè 260–310°C). Apre yo fin fonn, yo kapab mouye twal fib vè epi difize/fonn ak sifas fim PTFE.Pandan pwosesis la, fim FEP/PFA yo plase ant fim PTFE ak twal fib vè, epi li chofe ak ko-faye.

Konklizyon

Rezime, lyezon ki genyen ant PTFE kouch ak twal fib vè Teflon, twal segondè-tanperati a pa senplman 'kole' - se yon konplèks (pwosesis jeni sistematik): atravè lankraj fizik pou pran fib yo, atravè kou. plingagentsandprimertoachievechemicalbondingandtranzisyon,andthroughhigh-temperatureinteringtocompletethemelt-integrationofthefilmlayers.IfonlypurePTFEweredirectlycoated,theentirelayerwouldpeeloffwithasingletear.
