He aha i huaina ai ko te ngongo ptfe? He aha i tapaina ai ko te ngongo ptfe?
E kiia ana hoki te ngongo PolytetrafluoroethyleneNgongo PTFE, e mōhiotia whānuitia ana ko "Kingi Kirihou", he pūmua ngota teitei i hangaia mā te whakakotahi i te tetrafluoroethylene hei monomer. He mā te ware pi, he mārama, he ātete pai ki te wera me te makariri, ka taea te whakamahi mō te wā roa i te -180～260ºC. Kāore he tae, he tāpiri rānei i roto i tēnei rauemi, he āhuatanga ātete ki te waikawa, te kawakore, me ngā momo whakarewa waro, ā, tata kore e rewa i roto i ngā whakarewa katoa. I taua wā anō, he āhuatanga ātete pāmahana teitei te PTFE, ā, he tino iti te tauwehenga waku, nō reira ka taea te whakamahi mō te whakahinuhinu me te noho hei paninga pai mō te horoi ngāwari i te paparanga o roto o ngā paipa wai.
Tikanga whakaputa:
Ko te rauemi mata o te ngongo PTFE he paura, ā, ka taea te hanga mā te tukatuka kōpeketanga, te tukatuka whakaputa rānei.
Momo ngongo:
1. He mea hanga ngā ngongo pūwero maeneene mai i te kapia PTFE 100% hou, kāore he tae, he tāpiringa rānei. He pai mō te whakamahi i roto i te Hangarau Waka me te Ātea, te Hikohiko, ngā Wāhanga me ngā Ārai Mate, te Hanga Matū me te Rongoā, te Tukatuka Kai, ngā Pūtaiao Taiao, te Tātari Hau, ngā Pūrere Whakawhiti Wai me ngā Pūnaha Tukatuka Wai. Kei te wātea ngā momo ārai-pūmau (kātene) me ngā momo tae rānei o ngā ngongo katoa.
2. He mea hanga ngā ngongo piko mai i te kapia PTFE 100% hou, kāore he tae, he tāpiringa rānei. He tino pai te ngāwari me te ātete kikī mō te mahi pai rawa atu mō ngā tono e hiahiatia ana he radius piko kikī ake, he ātete pēhanga nui ake, he ātete kuru rānei. Ka taea te tiki ngongo piko mai i ngā mura, ngā flanges, ngā poroporo, te whakakotahitanga rānei o ngā Otinga Ngongo Arotau neke atu i te kotahi. Kei te wātea ngā putanga ārai-pūmau (waro) o ngā ngongo katoa.
3. Ngā ngongo pūwero Kua whakamahia whānuitia ngā āhuatanga pāmahana me te ātete waikura o ngā ngongo pūwero i roto i ngā ahumahi ātete waikura, pērā i te ahumahi matū, te whakapūkara, te whakakikorua hiko, te rongoā, te whakakorikori me ētahi atu ahumahi. Ko te nuinga o te ngongo pūwero he ātete waikura tino pai, he ātete paru pai, he ātete koroheketanga pai, he pai te mahi whakawhiti wera, he iti te ātete, he iti te rahi, he mama te taumaha me te hanganga kiato.
Ngā Āhuatanga me te Pūmautanga:
1. Ātete pāmahana teitei, kāore e rewa i roto i tētahi whakarewa. Ka taea e ia te tu atu i te pāmahana teitei ki te 300℃ i roto i te wā poto, ā, ka taea te whakamahi tonu i waenga i te 240℃~260℃, ā, he tino pumau te pāmahana. Haunga te tauhohenga ki ngā konganuku kawakore rewa, kāore e waikurahia e tētahi matū, ahakoa i kohuatia ki te waikawa hauwaiwai, te aqua regia, te waikawa whanariki paowa, te konutai hauwaiwai, e kore e rerekē.
2. Ātete pāmahana iti, pakari ā-mīhini pai i te pāmahana iti, ahakoa ka heke te pāmahana ki te -196 ℃ me te kore e pakarukaru, ka taea te pupuri i te 5% te roa.
3. Ātete ki te waikura, ngoikore ki te nuinga o ngā matū me ngā whakarewa, ātete ki ngā waikawa kaha me ngā kawakore, te wai me ngā whakarewa rauropi maha, ā, ka taea te tiaki i ngā wāhanga mai i tetahi momo waikura matū.
4. Ārai-pakeketanga, i raro i te kawenga nui, he rua ngā painga o te ātete ki te kakahu me te kore e piri. He roa te ora o te kirihou mō te pakeketanga.
5. He hinu whakahinuhinu teitei, koinei te tauwehenga waku iti rawa i roto i ngā rauemi totoka. Ka rerekē te tauwehenga waku ina paheke te kawenga, engari ko te uara kei waenganui i te 0.05-0.15 anake.
6. Kore-piri, koinei te mea he iti rawa te taumahatanga o te mata i roto i ngā rauemi totoka, ā, kāore e piri ki tētahi matū. Kāore te nuinga o ngā matū e piri ki reira. He pai hoki ngā āhuatanga kore-piri o ngā kiriata tino angiangi.
7. He mā, kāore he kakara, kāore he reka, kāore he paitini, ā, kāore e ngoikore te tinana. Hei oko toto horihori, hei okana horihori hoki kua whakatōkia ki roto i te tinana mō te wā roa, kāore he pānga kino.
8. He mama, he ngāwari hoki. Ka taea e ia te whakaiti i te kaha o te mahi a te kaiwhakahaere.
9. He whānui ngā painga o tēnei hua, he roa ake te ora o te whakamahinga i ngā momo ngongo mamaoa o nāianei, kāore e hiahiatia kia whakakapia mō te wā roa, he whakaiti nui i te utu whakamahinga, he whakapai ake i te whai huatanga o te whakamahinga, he ōhanga me te whai hua.
