Kodi PTFE ndi Glass Fiber Bond Popanda Delamination Popanda Chemical Bond?

Jiangsu Aokai New Materials, wopanga nsalu zotentha kwambiri za PTFE, akufotokoza kuti:

Polytetrafluoroethylene (PTFE) ndi galasi fiber (makamaka yopangidwa ndi silika) sangathe kupanga zomangira za mankhwala. PTFE ili ndi mphamvu yotsika kwambiri (pafupifupi 18 mN/m), yomwe imadziwika kuti 'yopaka yopanda ndodo', pomwe ulusi wagalasi ndi hydrophilic polar inorganic material. Awiriwa mwachibadwa sagwirizana.

Ku Aokai, timayika nsalu zamagalasi ndi emulsion ya PTFE, makamaka kudzera m'njira zotsatirazi:Ngakhale kuti PTFE yokha ndiyovuta kulumikiza, cholumikizira (monga silane) chingagwiritsidwe ntchito pomanga mlatho pamtunda wa galasi. Mfundo yake ndi: Glass fiber pamwamba ndi yokutidwa ndi silane coupling agent. Mapeto amodzi a silane (gulu la alkoxy) amakumana ndi condensation ndi magulu a silanol (Si-OH) pa galasi la galasi kuti apange mgwirizano wa mankhwala; mapeto ena (monga gulu la amino, gulu la epoxy) limagwira ntchito.

Ngati PTFE palokha ndi osachiritsidwa, yotakataka mapeto a coupling wothandizila sangathe kugwirizana ndi PTFE, kotero pamwamba mankhwala chofunika. Chizoloŵezi chodziwika bwino ndikuwonjezera ma coupling agents ndi zomangira ma polima (monga PFA, FEP - perfluoroalkoxy resin kapena tetrafluoroethylene-hexafluoropropylene copolymer, zomwe zimasungunuka-processable fluoroplastics) mu PTFE emulsion.

Transition layer : Perfluoroalkoxy resin kapena tetrafluoroethylene-hexafluoropropylene copolymer imagwiritsidwa ntchito ngati gawo lapakati. Ma fluoroplastics awa ali ndi mankhwala abwino ogwirizana ndi PTFE, amatha kusungunuka ndi kuyenda pamtunda wotsika, amangiriza magalasi opangidwa ndi silane ndi PTFE yochuluka, kupanga mawonekedwe a gradient, ndi kuthetsa kusintha kwa maganizo.

Kugwirizana pakati pa PTFE ndi magalasi fiber kwenikweni ndi kuphatikiza kwakuthupi kumakina olumikizirana + kupsinjika + kupsinjika + gradient kusintha wosanjikiza..

Zambiri pamwambapa zimaperekedwa ndi Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mudziwe zambiri, zochitika zamagwiritsidwe ntchito ndi mayankho makonda amtundu wathu wonse - kuphatikiza nsalu yotentha kwambiri ya PTFE, tepi ya PTFE yotentha kwambiri, lamba wa PTFE wotentha kwambiri, lamba wopanda waya wamakina omangira, nsalu imodzi ya PTFE, lamba wotenthetsera wotentha kwambiri ndi zinthu zina, chonde osamva magalasi - chonde osamva magalasi.
