Xihloko lexi xi katsa mintirho ya PTFE eka thermal insulation cladding ya tinjhini ta swibuluki. Maendlelo ya mune: Endothermic decomposition — PTFE yi depolymerizes eka ~400°C kuya eka tetrafluoroethylene (endothermic yale henhla, ~3,000°C combustion gas exposure), yi tswonga kuhisa lokukulu xikan’we naku humesa matimba yo hisa kusuka eka vuandlalo bya rirhangu. Ku kufumela ka transpiration na ku pfaleriwa ka filimi ya gasi — tigasi to bola (tetrafluoroethylene) ti nghena ehandle hi ti micro-pores, ti susa ku hisa ka le henhla; filimi ya gasi leyi khulukaka yi hambanyisa gasi yo hisa ya mahiselo yale henhla kusuka eka rirhangu, leswi hungutaka ku khuluka ka kuhisa ekusuhi na rirhangu hi >50%; filimi ya gasi yi cinca rivilo/mahiselo ya leyara ya ndzilakano, ku hunguta ku khuluka ka swiphemuphemu.

Xitlhokovetselo lexi xa xithekiniki kusuka eka Jiangsu Aokai xi kambisisa hilaha mahiselo yale hansi kumbe yale henhla ya sintering ya onhaka hakona lapi ra mahiselo yale henhla ya PTFE. Ku sintering yale hansi swisiya ti particles tinga n’oki, leswi endlaka leswaku ti micro-pores, weak coating-substrate bonding, swiphemu swo khwaxa, matimba ya kahle ya michini, xikan’we na milky opaque appearance. Ku hisa ngopfu swi hlohletela ku onhaka ka mahiselo ya PTFE, leswi humesaka ti pinholes, ti bubbles, brittleness, ku cinca ka muhlovo wotshuka kuya eka ntima, xikan’we naku humesa musi wa chefu. Swilo leswimbirhi leswi hundzeletiweke swi herisa ku hlangana, matirhelo yo ka ya nga namarheli, ku cinca-cinca, ku pfalela, na ku tshamiseka ka dimensional.

Ku cheriwa ka PTFE aswi pimiwi eka lapi ra fiberglass ntsena. Atikili leyi yi tivisa 7 wa ti substrates tin’wana – aramid, carbon fibre, PBI, porous metal, graphite, asbestos (phased out), na ti ceramic fillers – na swihlawulekisi swa tona swa maendlelo, swipfuno, swipimelo, na matirhiselo ya nkoka.

Tanihi muendli wa xiphurofexinali wa malapi ya mahiselo ya le henhla ya PTFE, Jiangsu Aokai New Materials yi ku nyika vutivi bya xiphurofexinali. Xikongomelonkulu xa vutshunguri bya le henhla bya fiberglass i ku aka buloho ra molecular exikarhi ka fiberglass leyi nga riki ya ntumbuluko na PTFE ya organic, leswaku hi xisekelo ku tlhantlha inc ya vona ya ntumbuluko
