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.

Nsalu yopumira kwambiri ya PTFE yotentha kwambiri imaphatikiza zinthu zopanda ndodo, kukhazikika kwamafuta, komanso kuthekera kwa mpweya. Nkhaniyi ikuwunika momwe imagwirira ntchito pakuyanika nsalu, kukonza chakudya, kupanga zinthu zambiri, zamagetsi, zotumiza mpweya, kuteteza chilengedwe, ndi zida zomangira.

Nkhaniyi ikufotokoza momwe mungapewere kuipitsidwa ndi kuwonongeka kwa ntchito pa mbali yosamatira ya PTFE tepi yotentha kwambiri panthawi yophimba. Njira zazikuluzikulu zikuphatikiza kuyang'anira magwero (kuchiza molondola pamwamba), kudzipatula pathupi (makanema oteteza, zodzigudubuza zopanda ndodo, zowumitsa zone), ndikuwongolera njira zoyengedwa.

Nkhaniyi ikufotokoza chifukwa chake nsalu ya fiberglass yopanda alkali ndiye gawo lapansi lokondedwa la nsalu za PTFE zotentha kwambiri. Imakhudza kulumikizana kwamankhwala kudzera pa ma silane coupling agents ndi zinthu zofunika kwambiri monga kukhazikika kwamafuta, kukhazikika kwa mawonekedwe, komanso kukana kwa dzimbiri - kuwonetsetsa kuti zikugwira ntchito kwanthawi yayitali m'malo ovuta.

Kuyika PTFE kutentha tepi mwamphamvu pa yokhotakhota ndi kusakhazikika pamalo popanda thovu ndi m'mphepete warping, ndi muyezo ntchito ndondomeko n'kofunika, kuphatikizapo bwinobwino gawo lapansi pretreatment, luso ntchito akatswiri ndi miyeso yoyenera wothandiza. Pakati pawo, pretreatment substrate ndiye gawo lovuta kwambiri, lomwe limatsimikizira pafupifupi 70% ya zotsatira zomaliza.

Potengera zomwe zikuchulukirachulukira malamulo achilengedwe, PFOS/PFOA-free PTFE emulsion ndi chinthu chomwe chasinthidwa kuti chilowe m'malo mwachikhalidwe cha PFOA chokhala ndi polymerization. Imasunga zofunikira za PTFE pomwe imathandizira kwambiri chilengedwe komanso chitetezo chaumoyo.

The matenthedwe kukulitsa coefficient ya PTFE mkulu kutentha nsalu si mtengo wokhazikika. Imakhalabe yotsika kwambiri kutentha kwa 100 ° C (pafupifupi 0.5×10⁻⁵/°C), komabe imakwera kwambiri pansi pa kutentha kwakukulu.

Monga katswiri wopanga nsalu za PTFE zotentha kwambiri, Jiangsu Aokai New Materials amagawana njira zopalira. Kuti mupewe ma burrs, delamination ndi kupatuka kwapang'onopang'ono pakudula, ndikofunikira kuwongolera mwadongosolo zinthu zinayi zofunika: zida zodulira, zida, zida ndi zida.

Monga opanga oyambirira a PTFE matepi otentha kwambiri, Jiangsu Aokai New Materials apa akulongosola zotsatira za njira zoziziritsira ndi kuziziritsa pakuchita kwa matepi ochiritsidwa a PTFE. Makhalidwe a PTFE Crystallization Makhalidwe ndi Kuzizira kwa Rate RegulationThe PTFE su

Monga katswiri wopanga nsalu za PTFE zotentha kwambiri, Jiangsu Aokai New Materials amakutengerani kuti mudziwe zambiri. Nthawi zambiri, guluu wochiritsidwa ndi utomoni amatha kupukuta kuchokera pansalu yapamwamba ya PTFE yotentha kwambiri ndipo palibe zotsalira. Komabe, chotsatira ichi sichiri mtheradi. Yeniyeni
