I roto i te ao uaua o te hiri ahumahi, he rauemi rongonui te Polytetrafluoroethylene (PTFE) mō tōna ātete matū tino pai, te iti o te waku, me te kaha ki te mahi puta noa i te whānuitanga o te pāmahana. Heoi, ina neke ngā tono mai i ngā āhuatanga pūmau ki ngā āhuatanga hihiri—me ngā pēhanga rerekē, ngā pāmahana, me te nekehanga tonu—ko ngā āhuatanga tonu e whai hua ai te PTFE ka puta he wero hangarau nui. Ka rukuhia e tēnei tuhinga te ahupūngao kei muri i te whanonga o te PTFE i roto i ngā taiao hihiri, ā, ka tūhuratia ngā rautaki hoahoa kua pakari, kua whakamātauhia e āhei ai tōna whakamahinga angitu i roto i ngā tono nui mai i te rererangi ki ngā pūnaha motuka mahi-teitei.
Ⅰ. Te Wero Matua: Ngā Āhuatanga Rauemi o te PTFE e Nekeneke ana
Ehara te PTFE i te elastomer. He rerekē rawa tōna whanonga i raro i te ahotea me te pāmahana i ngā rauemi pēnei i te NBR, i te FKM rānei, ā, me rerekē te huarahi hoahoa. Ko ngā wero matua o te hiri hihiri ko:
Rere Matao (Ngokingoki):He āhua rerekē te PTFE i raro i te ahotea ā-pūkaha tonu, he āhuatanga e mōhiotia ana ko te rere makariri, te ngokingoki rānei. I roto i te hiri hihiri, ka taea e te pēhanga me te waku tonu te whakapōturi i te PTFE, ka ngaro te kaha hiri tuatahi (kawenga) ā, i te mutunga, ka pakaru te hiri.
Tauwehenga Ātete Iti:He rauemi ngohengohe te PTFE, he iti te ngāwari. Kāore i rite ki te mowhiti-O rapa ka taea te hoki ki tōna āhua taketake i muri i te whakarerekētanga, he iti noa te whakaoranga o te PTFE. I roto i ngā āhuatanga o te huringa pēhanga tere, o ngā huringa pāmahana rānei, ka kore e taea e te ngoikore o te pakari te pupuri i te hononga pumau o te hiri ki ngā mata hiri.
Ngā Pānga Whakawhanui Wera:He maha ngā huringa pāmahana nui e pāngia ana e ngā taputapu hihiri. He nui te tauwehenga whānui wera o te PTFE. I roto i te huringa pāmahana teitei, ka whānui te hiri PTFE, ka piki ake pea te kaha hiri. Ina whakamatao, ka whakawhāiti, ka taea te whakatuwhera i te āputa me te turuturu. Ka nui ake te kino o tēnei nā te rerekētanga o ngā tere whānui wera o te hiri PTFE me te whare/pou whakarewa, ka whakarerekē i te ātea mahi.
Ki te kore e aro ki ēnei āhuatanga ā-roto o te rauemi, kāore e pono te hiri PTFE noa mō ngā mahi hihiri.
Ⅱ. Ngā Otinga Hangarau: Me pēhea te Whakautu a te Hoahoa Atamai i ngā Herenga Rauemi
Ko te whakautu a te umanga ki ēnei wero ehara i te whakakore i te PTFE engari ko te whakanui ake mā te hoahoa miihini atamai. Ko te whāinga he whakarato i tētahi kaha hiri pumau, pono e kore e taea e te PTFE anake te pupuri.
1. Ngā Hiri Whakakahangia e te Puna: Te Paerewa Koura mō te Mahi Hihiri
Koinei te otinga tino whai hua, ā, he whānuitia hoki te whakamahinga mō ngā hiri PTFE hihiri. Ko te hiri whakakaha-puna he mea hanga ki te koti PTFE (ki tētahi atu pūmua rānei) e takai ana i tētahi puna whakarewa.
Te Mahi: He pūtake pūngao pumau, kaha-teitei te puna. Ka pana tonu i te ngutu PTFE ki waho ki te mata hiri. I te wā e pakaru ana, e rere ana rānei te koti PTFE i te makariri, ka whānui te puna hei whakakapi, ka mau tonu te kawenga hiri tata tonu puta noa i te roanga o te mahi a te hiri.
Pai rawa atu mō: Ngā tono me ngā huringa pēhanga tere, ngā awhe pāmahana whānui, te iti o te hinu whakahinuhinu, me te mea nui te tere turuturu tino iti. Ko ngā momo puna noa (cantilever, helical, conted coil) ka tīpakohia i runga i ngā whakaritenga pēhanga me te waku motuhake.
2. Ngā Rauemi Whakakotahi: Te Whakapai Ake i te PTFE mai i Roto
Ka taea te whakakotahi i te PTFE ki ngā momo whakakī hei whakapai ake i ōna āhuatanga miihini. Ko ngā whakakī noa ko te muka karāhe, te waro, te karāhe, te parahi, me te MoS₂.
Te Mahi: Ka whakaitihia e ēnei whakakī te rere makariri, ka whakanui ake i te ātete kakahu, ka whakapai ake i te kawe wera, ā, ka whakarei ake i te kaha pēhi o te PTFE turanga. Mā tēnei ka pumau ake te hiri i ngā āhuatanga, ā, ka pai ake te tū atu ki ngā taiao whakakoi.
Pai rawa atu mō: Te whakarite i te mahi hiri kia rite ki ngā hiahia motuhake. Hei tauira, ka whakarei ake ngā whakakī waro/karāpiti i te hinu whakahinuhinu me te ātete ki te kakahu, ko ngā whakakī parahi ka whakapai ake i te kawe wera me te kaha ki te kawe kawenga.
3. Ngā Hoahoa Mowhiti-V: He Māmā, he Whai Hua hoki te Hiritanga Tuaka
Ahakoa ehara i te hiri porowhita tuatahi, he tino pai ngā mowhiti-V PTFE mō ngā tono tuaka hihiri.
Te Mahi: He maha ngā mowhiti-V e whakarārangihia ana. Mā te pēhanga tuaka i te wā o te huihuinga ka whānui haere ngā ngutu o ngā mowhiti, ka hangaia te kaha hiri. Ka whakaratohia e te hoahoa he pānga whakaea-ake mō te kakahu.
Pai rawa atu mō: Te tiaki i ngā peera tuatahi mai i te poke, te mahi hei waru māmā, hei ngutu puehu rānei, me te whakahaere i te nekehanga tuaka.
Ⅲ.Tō Rārangi Arowhai Hoahoa mō te Kōwhiringa Hihiri PTFE Hihiri
Hei whiriwhiri i te hoahoa hiri PTFE tika, he mea nui te whai i tētahi huarahi pūnaha. I mua i te kōrero ki tō kaiwhakarato, kohia ēnei raraunga tono nui:
Āhua Pēhanga: Ehara i te mea ko te pēhanga mōrahi anake, engari ko te awhe (iti/mōrahi), te auau huringa, me te tere o te huringa pēhanga (dP/dt).
Awhe Pāmahana: Ngā pāmahana mahi iti rawa me te pāmahana mahi mōrahi, tae atu ki te tere o ngā huringa pāmahana.
Momo Nekehanga Hihiri: Hurihuri, hurihuri, hurihuri rānei? Whakaurua te tere (RPM) te auau rānei (huringa/meneti).
Pāpāho: He aha te wai, te hau rānei e hiritia ana? Ko te hototahi te mea nui.
Te Auau o te Tātaritanga e Whakaaetia ana: Tautuhia te turuturu mōrahi e whakaaetia ana (hei tauira, cc/hr).
Ngā Rauemi Pūnaha: He aha ngā rauemi o te pou me te whare? He mea nui te pakeke me te āhua o te mata mō te pakaru.
Ngā Āhuatanga Taiao: Te noho mai o ngā poke whakakoi, te pānga o ngā hihi UV, ētahi atu āhuatanga o waho rānei.
Whakamutunga: Te Hoahoa Tika mō ngā Ahumahi Tino Hiahia
He rauemi hiri tino pai tonu te PTFE mō ngā taiao uaua. Ko te kī ki te angitu kei roto i te whakaae ki ōna herenga me te whakamahi i ngā otinga hangarau pakari hei wikitoria i aua herenga. Mā te mārama ki ngā mātāpono kei muri i ngā hiri whakakaha-puna, ngā rauemi hiato, me ngā āhuahanga motuhake, ka taea e ngā kaihangarau te whakatau whai whakaaro hei whakarite i te pono mō te wā roa. I Yokey, he tohunga mātou ki te whakamahi i ēnei mātāpono hei whakawhanake i ngā otinga hiri tino tika. Ko tō mātou tohungatanga kei roto i te āwhina i ngā kiritaki ki te whakatere i ēnei taupatupatu uaua ki te whiriwhiri, ki te hoahoa ritenga rānei i tētahi hiri e mahi tika ana i raro i ngā āhuatanga hihiri tino uaua.
