I roto i te mara o ngā rauemi kirihou,PTFE(polytetrafluoroethylene) he otinga tino pai, he maha hoki ngā whakamahinga. Nā ōna āhuatanga tino pai me te whānuitanga o ngā whakamahinga, kua waiho hei rauemi tino nui i roto i ngā ahumahi maha. I roto i tēnei pou rangitaki, ka tūhuratia e mātou ngā āhuatanga me ngā painga o ngā tokotoko PTFE, e wātea ana i roto i ngā āhua kua whakaputahia me ngā āhua kua whakarewaina.
Mai i ngā momo kua whakapūtāhia, ka hangaia ēnei tokotoko i ngā rahi paerewa katoa, mai i te 1/8" te whānui ki te 8". Ko te roa whānui o te tokotoko PTFE kua whakapūtāhia he 1000mm, ā, he whānui te whakamahinga. I tētahi atu taha, ko te mea kua whakapūtāhiatokotoko PTFEKei te wātea ngā rahi tae atu ki te 16 inihi te whānui, ā, ko te roa mōrahi ko te 300 mm. Mā te whānuitanga o ngā rahi ka taea e ngā kaihoko te kimi i te hua e tino tika ana mō ā rātou hiahia.
Ko tētahi o ngā painga nui otokotoko PTFEKo te s te mahi whakarei ake mā te whakamahi i ngā rauemi whakakī (whakapakari). Ka taea te hanga i ēnei tokotoko ki ngā rauemi whakapakari maha pērā i te muka karāhe, te karāhe me te parahi. Ka whakapai ake ēnei whakakaha i ngā āhuatanga ā-pūkaha o te PTFE, ā, he mea pai mō ngā tono uaua.
Ko te ātete ki te huarere tētahi o ngā āhuatanga matua o ngā rākau PTFE, he roa ake te ora o te rauemi i roto i ngā kirihou. Ko te tikanga tēnei ka taea e ngā rākau PTFE te tu atu ki ngā āhuatanga huarere kino me te kore e ngaro ō rātou āhuatanga, e pirau rānei i roto i te wā. Hei tāpiri,tokotoko PTFEHe tino ātete ki te waikura, ā, he mea tino pai mō ngā tono e pā ana ki ngā waikawa kaha, ngā kawakore, te wai, me ngā whakarewa waro rerekē.
Ko tētahi atu āhuatanga rongonui o ngā rākau PTFE ko tōna kaha whakahinuhinu teitei, e kiia ana ko te mea iti rawa te tauwehenga o te waku i roto i ngā kirihou. Me te tauwehenga o te waku he iti iho i te 0.04, ka whakaratohia e ngā rākau PTFE he whakahinuhinu tino pai, ka whakaiti i te kakahu me te whakarite kia maeneene te mahi i roto i ngā momo tono.
Ko tētahi o ngā āhuatanga matua o te PTFE ko tōna kaha ki te tu atu i ngā pāmahana tiketike.tokotoko PTFEKa taea e ngā rakau PTFE te tu atu i ngā pāmahana roa mai i te 200 ki te 260 nekehanga Celsius, e pai ai mō ngā mahi i roto i ngā taiao tino pāmahana teitei. Mā tēnei ātete wera pai rawa atu ka whakarei ake i te pono me te roa o ngā rakau PTFE.
He rerekē, he tino pai hoki te mahi a ngā tokotoko PTFE i ngā pāmahana iti. Ahakoa ka heke te pāmahana ki te -196 nekehanga Celsius, ka taea tonu e te tokotoko PTFE te pupuri i te roa o te 5%, e whakaatu ana i tōna ngāwari me tōna ngāwari i raro i ngā āhuatanga tino makariri.
Hei tāpiritanga, ka taea te whakairo i ngā tokotoko PTFE hei here, kia mau ai ngā hononga, kia whānui ake ai hoki te whakamahinga. Nā tēnei āhuatanga ka pai ai ngā tokotoko PTFE mō ngā kaupapa hanganga me te hangarau.
Hei whakamutunga, he otinga maha ngā mahi, he pono hoki ngā tokotoko PTFE, he tino pai hoki ōna āhuatanga. E wātea ana i roto i ngā āhua kua whakapūtātia, kua whakakōpiritia hoki, me ngā momo rahi rerekē, e āhei ai te ngāwari ki te whakatutuki i ngā whakaritenga tono rerekē. Mā te mahi whakarei ake e tutukihia ana e te rauemi whakakaha ka whānui ake te whānuitanga o ngā tono oNgā rākau PTFEMai i te ātete ki te huarere me te waikura ki te kaha whakahinuhinu, te ātete ki te pāmahana, tae noa ki te mahi cryogenic, he huinga kounga kore e taea te whakataurite i ngā tokotoko PTFE. Nō reira, ahakoa e hiahia ana koe ki tētahi rauemi pono mō ngā tono hanganga, ki te umanga matū, ki tētahi atu mea rānei, whakaarohia ngā tokotoko PTFE mō tōna mahi tino pai me te roa o te mau.
