Usha Polytetrafluoroethylene waa walax leh xasillooni kiimiko oo aad u fiican, xoog farsamo iyo xasillooni kuleyl, waana nooc ka mid ah walxaha polytetrafluoroethylene (PTFE). PTFE waa walax macmal ah oo leh sifooyin aad u fiican waxaana badanaa loo isticmaalaa soo saarista waalka, shaabadaha, weelasha, tuubooyinka, dahaarka fiilooyinka iwm.
Usha PTFE guud ahaan waxaa laga sameeyaa walxaha PTFE ee polymerized, kuwaas oo leh iska caabin aad u wanaagsan heerkulka sare, daxalka, xoqidda iyo dahaarka, iyo sidoo kale iska caabin aad u sareysa oo ku wajahan gabowga iyo iska caabinta saliidda iyo dareerayaasha. Sidaa darteed, usha PTFE aad bay ugu habboon tahay in loo isticmaalo shaabado, buuxiyeyaal waalka, dahaar-qaadayaal, gudbiyeyaal, iwm. ee beeraha kiimikada, daawada, elektaroonigga, korontada, hawada sare iyo wax soo saarka mashiinnada.
Intaa waxaa dheer, usha PTFE ma aha oo kaliya inay leedahay iska caabin daxalka oo aad u fiican, laakiin sidoo kale waxay leedahay iska caabin heerkul sare oo aad u fiican, usha PTFE waxaa loo isticmaali karaa ilaa heerkulka ugu badan ee 260 ℃. Isla mar ahaantaana, waxay sidoo kale leedahay sifooyin koronto oo aad u fiican, sidaa darteed usha PTFE sidoo kale si weyn ayaa loogu isticmaalaa soo saarista fiilooyin iyo fiilooyin kala duwan, qaybo dahaadh ah, guddiyo kiristaal dareere ah iyo qaybo kale oo elektaroonik ah.
Usha PTFE waa walxo polymer ah oo leh isticmaalyo kala duwan iyo waxqabad aad u wanaagsan, waxayna leedahay codsiyo muhiim ah oo warshado kala duwan ah.
