Ma condens kudzera pa Si-OH ndi magulu a hydroxyl pa galasi fiber pamwamba; magulu ogwirira ntchito amapanga zomangira zamagulu kapena kumangirizidwa kwakuthupi → milatho ya mamolekyulu, kukulitsa kumamatira kwa zokutira
Titanate Coupling Agent
Monoalkoxy & chelate titanates
Kukana kutentha kwabwino kogwirizana ndi machitidwe a fluoropolymer; imapangitsa kunyowetsa kwa PTFE pa fiberglass, kumachepetsa kuwonongeka kwapakati pa kutentha kwakukulu
Classic oyambirira zomatira mankhwala; inathetsedwa chifukwa cha zovuta zachilengedwe & zobwezeretsanso zinthu ngakhale zili ndi zotsatira zabwino
Inorganic Nano Sol
silika sol, aluminiyamu sol
Amapanga nano-scale rough topography pa ulusi pamwamba pa makina okhazikika; nthawi zambiri amaphatikizidwa ndi ma coupling agents
Mtundu woyamba wa polymeric
Low-molecular-weight PTFE / FEP / PFA kubalalitsidwa, resin primer osakanikirana ndi coupling wothandizira
Amapanga ultra-thin transitional transitional layer fluoropolymer pa fiberglass kuti athandizire kulumikizana kwa topcoat; amachepetsa kwambiri chiopsezo cha delamination
Aokai PTFE imagwiritsa ntchito kuphatikiza kwa epoxy silane ndi ma fluorinated coupling agents pansalu yathu ya PTFE yotentha kwambiri. Kukonzekera uku kumapirira 260 ° C mosalekeza ntchito popanda kuwonongeka kwa mawonekedwe - kutsimikiziridwa ndi kuyesa kwa kutentha kwa maola 3,000.
Impact pa Core Properties za PTFE High-Temperature Nsalu
Kugwira ntchito ngati sing'anga pakati pa magalasi opangidwa ndi magalasi ndi organic fluoroplastic, kalasi ya wothandizira mankhwala ndi kukonza kumawongolera magwiridwe antchito onse.
Kumangirira kwa mankhwala + kusokoneza thupi; ❖ kuyanika kumalimbana ndi peeling pansi pa kusinthasintha mobwerezabwereza ndi kugwedezeka kwa kutentha
Zovuta kwambiri: Mphamvu ya peel ndiye chinthu chofunikira kwambiri pa moyo wotopa komanso kukana delamination.
2. Kulimbana ndi Kutentha & Kukhazikika kwa Matenthedwe
Zolumikizana zosagwirizana ndi kutentha kwambiri (zokhala ndi benzene kapena heterocyclic, mwachitsanzo, ma epoxy & acyloxy silanes) zimapirira mosalekeza 260°C ndi nsonga zaposachedwa>300°C - zofananira ndi machitidwe a PTFE.
Zowonjezera za organic zimawola pa kutentha kokwera → zing'onozing'ono zapakati pa nkhope, kusinthika kwachikasu, kuyanika kwapang'onopang'ono.
Tanthauzo la kugwiritsa ntchito: Pazogwiritsa ntchito kutentha kwambiri, onetsetsani kuti chomalizacho chili chokhazikika, osati zokutira za PTFE zokha.
3. Coating Compactness & Dielectric Performance
Kusintha kofanana kwa silane kumawonjezera kufalikira kwa emulsion ya PTFE ndi kunyowetsa pamwamba pa ulusi → zokutira mosalekeza zokhala ndi ma pinholes ochepa ndi ma microcracks → zofunika kwambiri pakuwonongeka kwamagetsi ndi kuthekera kwa kutchinjiriza.
Mankhwala ochizira opangidwa ndi hygroscopic kapena ayoni amawonjezera kutayika kwa dielectric. High-purity silane imatengedwa kuti ikhale ya premium-grade PTFE nsalu kuti achepetse kusokoneza zonyansa.
4. Chemical Resistance & Moisture Barrier
Mtundu wa Agent
Zotsatira
Fluorinated coupling agent
Chikhalidwe cha hydrophobic & oleophobic
Inorganic nano sol
Chotchinga chotchinga chimateteza ulusi wamagalasi kuti usawotchedwe ndi hydrofluoric acid ndi media zowononga
