I roto i te oranga o ia ra ka kite tatou i te ngongo ptfe, na, ptfe ngongo i roto i te tukanga o te tukatuka me aro tatou ki nga mea nui?
I roto i te tukanga hanga o te putorino PTFE raina maitai, Me ki kia utua whakarongo ki nga mea e whai ake nei:
1. te paipa maitai tuitui rite ki te rahi tūturu o te rauemi, te putorino maitai me te fehokotaki'anga mowhiti fehokotaki'anga, ka taea e te mowhiti te whakamahi ā-argon arc fehokotaki'anga, fehokotaki'anga splash ki te kōnae ki te horoi, me te fillet fehokotaki'anga ki te kokonga porotaka, kahore koi taha.
2. Toia he poka iti ki te pito o te paipa rino, kia marama te tohu, kaua hoki e araia.Ka whakamahia tenei poka ki te tuku i te toenga hau i waenga i te paipa maitai me te putorino tetrafluoroethylene i te wa e whakamahana ana, a ka whakamahia hei tirotiro mena kua pakaru te paipa tetrafluoroethylene me te patai i te wa o te whakamatautau pehanga.
3. Ko te putorino maitai me whakahuihui i mua i te whakakakahu.Me whakaemihia te hononga ki te papa koura asbestos o te matotoru tika, kia rite ki nga whakaritenga rahi katoa i muri i te ararewa.
4. i muri i te huihuinga o te putorino maitai ki te kirikiri ngingio maimoatanga, ki te tango i te waikura taiepa roto, a ka ki te hau kōpeke ki te horoi i te rua ngongo.Whakauruhia te ngongo tetrafluoroethylene ki roto i te ngongo maitai.Ki te kore e porotaka etahi putorino tetrafluoroethylene ka kore e taea te kuhu, me whakamahi te wai wera, te mamaoa, te oumu whakamahana auau reo hei whakamahana i te paipa tetrafluoroethylene, kaua e neke ake te mahana whakamahana i te 100 ℃.
5. Whakaarohia te roa o te flanging ina tapahia te paipa teflon.Ko te tikanga, 35-40 te roa ka wehea ki runga ake i te mata whakakai.Me whakanoho he putea koura asbestos ki runga i te ngongo TEflon i mua i te pupuhi.Ko te pupuhi i te ngongo teflon kia rua nga hikoinga, tuatahi ki roto i te pere, ko tenei kopa ma te whakamahi i tetahi waahanga konumohe riipene.I te wa e pupuhi ana, whakawerahia te vivipary ki te mura oxyacetylene.Ka inehia te pāmahana o te taputapu ki te ine ine wera o te mata.Ko te pāmahana kia kaua e tiketike rawa.Me whakahaere te pāmahana i waenga i te 260 ℃ me te 280 ℃.I te wa e pupuhi ana, pehia ki raro te taputapu whanau kua wera.Ka tae te koha whanau ki te taha o te whakakai whakakai, kaua e pehi atu.I tenei wa, whakamatao ki te wai, ka tango i te taputapu whanau ina whakamatao ki te pāmahana a tawhio noa.Ko te flanging o te taahiraa tuarua ka whakaraeraehia te puha.He papatahi tenei.
6. i muri i te whakawera, ata pehia ki raro ka tino pehia kia papatahi, ka whakamatao ki te wai ki te pāmahana ambient, katahi ka tango i te mono.
7. te putorino raina ki te pereti matapo pai, ki roto i te puoto whakawera motuhake, hono ki te ngongo rangi kōpeke, whakawera i te rango ki te tikanga whakawera auau takawaenga, kia te pāmahana whānui o te paipa ki e pā ana ki 280 ℃, a ka āta haere 8-LOKGF/cm2 hau kōpeke.Kuhua te ngongo tetrafluoron ki roto i te taika wai, rukuhia te ngongo ki te wai, haere ata ki roto i te hau 15kgf/cm2, tirohia mena he mirumiru kei te poka, mena ka kitea, ka tohu kua pakaru te ngongo tetrafluoron.Ko te take ko te nuinga o te whakamahana koretake, te tere pikinga ranei.Me hiri nga pito e rua ki te pereti matapo rakau kia kore ai e pakaru te paipa tetrafluoron.
