He aha te rerekētanga i waenga i te PTFE me te ePTFE?
Ko te PTFE, he whakarāpopototanga mō te polytetrafluoroethylene, he fluoropolymer hangai o te tetrafluoroethylene. Haunga tōna ātete wai, arā, he ātete ki te wai,PTFEhe ātete ki ngā pāmahana tiketike; kāore e pāngia e te nuinga o ngā matū me ngā matū, ā, he mata tōna e kore rawa e piri.
Ngā momo kohinga puehu
Mō ngā kaikohi puehu maroke, e whakamahi ana i ngā tātari whare putea, e rua ngā kōwhiringa noa – ko ngā pūnaha rūrū (he pūnaha tawhito ēnei e onge haere ana i ia rā), e rūrūtia ai te putea kohikohi hei tango i ngā matūriki kua piri, me te pulse jet (e mōhiotia ana ko te horoi hau kōpeke), e whakamahia ana he pupuhi hau pēhanga teitei hei tango i te puehu mai i te putea.
Ko te nuinga o ngā whare putea he pēke roa, he āhua ngongo, he mea hanga ki te papanga whatu, ki te papanga whatu rānei hei rauemi tātari. Mō ngā tono he iti te puehu me te pāmahana hau o te 250 °F (121 °C) iti iho rānei, ka whakamahia hoki ngā kātere kore-whatu kua whakapikohia hei rauemi tātari hei utu mō ngā pēke.
Ngā Momo Pāpāho Pēke Tātari
Mō ngā rauemi e whakamahia ana hei hanga i ngā pāpāho tātari, he maha ngā kōwhiringa e wātea ana. Ka taea e ēnei rauemi te tu atu ki ngā pāmahana rerekē, ka whakarato i ngā taumata rerekē o te pai o te kohikohi, ka tautoko i ngā kaha rerekē ki te tu atu ki ngā rauemi whakakoi, ā, ka whakarato i ngā hototahitanga matū rerekē.
Ko ngā kōwhiringa rauemi (tērā pea ka whakaratohia i roto i te āhua whatu me/ranei te āhua whiri) ko te miro, te polyester, ngā whiri micro denier tino whai hua, te polypropylene, te nairona, te kiriaku, te aramid, te muka karāhe, te P84 (polyimide), te PPS (polyphenylene sulfide)
Ngā Momo Whakaotinga Pēke Tātari
Kia oti i a koe te whiriwhiri i tētahi rauemi mō ō putea tātari, ko tāu whiringa e whai ake nei ko te whakamahi i tētahi whakaotinga, kāore rānei. Mā te whakamahi i tētahi whakaotinga tika (he huinga whakaotinga rānei i ētahi wā) ka taea te whakapai ake i te roa o tō putea, te tukunga keke, me te tiaki i a koe mai i ngā āhuatanga tono kino.
Ko ngā momo whakaotinga ko te tahunga, te karaihe, te ātete ahi, te ātete waikawa, te ātete mura, te ātete patū, me te ātete hinu, hei tauira noa iho.
E rua ngā huarahi e taea ai te pani i te PTFE hei whakaotinga—hei kiriuhi angiangi, hei paninga/kaukau rānei.
Ngā momo PTFE Mutu
Me tīmata mā te whakaaro ki tētahi tātari whare pēke i roto i te āhua o tētahi pēke polyester kua whakamātauria. Ina whakamahia te pēke, ka uru ētahi o ngā matūriki puehu ki roto i ngā pāpāho. Ka kiia tēnei ko te tātari uta hohonu. Ina rūrūtia te pēke, ina whakaohokia rānei he hau kōpeke hei tango i ngā matūriki kua piri, ka taka ētahi o ngā matūriki ki roto i te hopper ka tangohia mai i te pūnaha, engari ka noho tonu ētahi ki roto i te papanga. I roto i te wā, ka nui haere ngā matūriki ka uru hohonu ki roto i ngā pūwero o te pāpāho, ka tīmata te matapo i te pāpāho tātari, ka whakaheke i te mahi a te tātari i ngā huringa o muri mai.
Ka taea te whakamahi i te kiriuhi ePTFE ki ngā putea noa me ngā putea miro i hangaia mai i ngā mea whatu me ngā mea whakairo. He angiangi rawa tēnei kiriuhi (whakaarohia te "takai kai kirihou" hei whakaatu i te tirohanga) ā, ka whakamahia i roto i te wheketere ki te mata o waho o te putea. I tēnei wā, ka nui ake te whai huatanga o te putea i te kiriuhi (ko te "whai huatanga" i tēnei horopaki e pā ana ki te maha me te rahi o ngā matūriki puehu e tātarihia ana). Mena ka whiwhi te putea polyester kāore i oti i te 99% te whai huatanga mō ngā matūriki e rua maikorona me te nui ake, hei tauira, ko te tāpiri i te kiriuhi ePTFE ka hua ake he 99.99% te whai huatanga mō ngā matūriki tae atu ki te 1 maikorona me te iti iho, i runga i te puehu me ngā āhuatanga whakahaere. Hei tāpiri, ko ngā āhuatanga maeneene, kore-piri o te kiriuhi ePTFE te tikanga ko te rūrū i te putea, te whakamahi rānei i te pupuhi pupuhi ka meinga kia tangohia te nuinga o te puehu kua piri, ā, ka whakakorea, ka whakaitihia rānei te tātari hohonu me te matapo mō te roanga o te ora o te kiriuhi (ka pirau ēnei kiriuhi i roto i te wā; me te whakanui ake i tō rātou roa, kaua e whakamahia tahi me ngā matūriki puehu whakakoi).
Ahakoa he momo whakaoti te kiriuhi ePTFE, e whakaaro ana ētahi ko te kupu "whakaoti PTFE" he kaukau, he rehu rānei i tētahi paninga wai o te PTFE ki runga i ngā rauemi tātari. I tēnei wā, ka takai takitahi ngā muka o ngā rauemi ki roto i te PTFE. Kāore e taea e tētahi whakaotinga PTFE o tēnei momo te whakanui ake i te pai o te tātari, ā, tera pea ka hohonu tonu te utaina o te putea, engari ki te whakamahia he pupuhi pahū, ka māmā ake te horoi i te putea nā te paninga maeneene e whakaratohia ana e te PTFE ki runga i ngā muka.
Ko tēhea te mea pai: He kiriuhi ePTFE, he paninga PTFE rānei?
Tērā pea ka piki ake te pai o te putea kua tāpirihia ki te kiriuhi ePTFE tae atu ki te 10X, neke atu rānei, ka ngāwari te horoi, ā, kāore e pāngia e te taumahatanga hohonu. Waihoki, he pai te kiriuhi ePTFE mō te puehu piri, hinuhinu. Hei whakataurite, kāore he putea kore-kiriuhi kua pania ki te whakaotinga PTFE e piki ake te pai, ā, ka mau tonu te taumahatanga hohonu, engari ka ngāwari ake te horoi i te mea kāore te whakaotinga e tangohia.
I ngā wā o mua, i ētahi wā, ko te kōwhiringa i waenga i te kiriuhi ePTFE me te whakaotinga PTFE i peia e te utu nā te mea he nui te utu o ngā kiriuhi, engari kua heke te utu o ngā putea kiriuhi i ngā tau tata nei.
Tērā pea ka ara ake te pātai: "Ki te kore e taea te hinga i te kiriuhi ePTFE mō te whai huatanga me te ārai i te uta hohonu, ā, ki te mea kua heke te utu o te putea kiriuhi kia paku noa iho te utu i te putea he PTFE te mutunga, he aha koe e kore ai e whiriwhiri i te kiriuhi ePTFE?" Ko te whakautu, kāore e taea te whakamahi i te kiriuhi i roto i te taiao he mea whakakoi te puehu nā te mea—ki te pena koe—kāore e roa te wā e mau ana te kiriuhi. Mō te puehu whakakoi, ko te mutunga PTFE te huarahi hei haere.
Ahakoa tēnei, he raruraru maha-ahu te whiriwhiri i te huinga tino tika o te pāpāho tātari me te whakaotinga tātari (ngā whakaotinga rānei), ā, ko te whakautu tino pai e whakawhirinaki ana ki ngā āhuatanga maha.
