Nkhaniyi ikukhudzana ndi ntchito za PTFE muzotchingira zotenthetsera zama injini a missile. Njira zinayi: Endothermic decomposition — PTFE depolymerizes at ~ 400°C to tetrafluoroethylene (highly endothermic, ~3,000°C kuyaka gas exposure), kutenga kutentha kwakukulu ndi kutulutsa mphamvu yotentha kuchokera pamwamba pa khoma. Transpiration kuzirala ndi mpweya filimu kutchinjiriza - kuwola mpweya (tetrafluoroethylene) amalowa kunja kudzera yaying'ono pores, kuchotsa pamwamba kutentha; filimu yothamanga ya gasi imalekanitsa mpweya woyaka kwambiri kuchokera pakhoma, kuchepetsa kutentha kwapafupi ndi khoma ndi> 50%; Kanema wa gasi amasintha liwiro / kutentha kwa malire, ndikuchepetsa kukokoloka kwa tinthu.

Chidule chaukadaulo ichi chochokera ku Jiangsu Aokai chikuwunika momwe kutentha kotsika kwambiri kapena kutentha kwambiri kumawonongera nsalu ya PTFE yotentha kwambiri. Low sintering masamba particles osasungunuka, kuchititsa micro-pores, ofooka ❖ kuyanika-gawo lapansi mgwirizano, zaukali pamalo, osauka makina mphamvu, ndi yamkaka opaque maonekedwe. Kutentha kwambiri kumapangitsa kuti PTFE iwonongeke, imatulutsa mapini, thovu, brittleness, kusinthika kwamtundu wachikasu ndi wakuda, komanso kutulutsa utsi wapoizoni. Zonsezi zimawononga kulimba, kusagwira ntchito, kusinthasintha, kusungunula, ndi kukhazikika kwa dimensional.

Kulowetsedwa kwa PTFE sikungokhala ndi nsalu za fiberglass. Nkhaniyi ikuwonetsa magawo asanu ndi awiri amtundu wina - aramid, carbon fiber, PBI, porous metal, graphite, asbestos (ochotsedwa), ndi zodzaza ndi ceramic - ndi machitidwe awo, ubwino, malire, ndi ntchito zazikulu.

Monga katswiri wopanga nsalu za PTFE zotentha kwambiri, Jiangsu Aokai New Materials imakupatsani luntha laukadaulo. Cholinga chachikulu cha chithandizo cha fiberglass pamwamba ndikumanga mlatho wa molekyulu pakati pa inorganic fiberglass ndi organic PTFE, kuti athe kuthana nawo
