Ko te Polytetrafluoroethylene (PTFE), e mōhiotia whānuitia ana ko te "kingi o ngā kirihou," he ātete matū tino pai, he iti te tauwehenga waku, me te pumau i roto i ngā pāmahana tino kino. Heoi, ko ōna herenga ā-roto—pērā i te ātete kakahu ngoikore, te iti o te pakeke, me te ngawari ki te ngokingoki—kua akiaki i te whanaketanga o teNgā hiato PTFEMā te whakauru i ngā whakakī pēnei i te muka karāhe, te muka waro, me te karāpeti, ka taea e ngā kaihanga te whakarite i ngā āhuatanga o te PTFE mō ngā tono uaua i roto i te rererangi, te motuka, me te hiri ahumahi. Ka tūhuratia e tēnei tuhinga te whakarei ake a ēnei whakakī i te PTFE, ā, ka whakaratohia he aratohu mō te whiriwhiri i te hiato tika i runga i ngā whakaritenga whakahaere.
1. Te Hiahia mō te Whakarerekētanga PTFE
He tino pai te PTFE parakore mō te ātete ki te waikura me te iti o te waku engari he ngoikore ā-mīhini. Hei tauira, kāore e ranea tōna ātete kakahu mō ngā tono hiri hihiri, ā, ka huri tōna āhua i raro i te pēhanga roa (rere makariri). Ka arohia ēnei take e ngā whakakī mā te mahi hei anga whakapakari i roto i te anga PTFE, ka whakapai ake i te ātete ngoki, te manawanui kakahu, me te kawe wera me te kore e whakararu i ōna painga matua.
2. Muka Karāhe: Te Whakakaha Utu-Whai Hua
Ngā Āhuatanga Matua
Ātete Paka: Ka whakaitihia e te muka karāhe (GF) te tere paka o te PTFE tae atu ki te 500 ngā wā, he mea tino pai mō ngā taiao taumaha.
Te Whakaiti Ngoki: Ka whakarei ake te GF i te pumau o ngā āhuatanga, ka whakaiti i te whakarerekētanga i raro i te ahotea tonu.
Ngā Herenga Wera me te Matū: He pai te mahi a te GF i ngā pāmahana tae atu ki te 400°C engari ka pirau i roto i te waikawa hauwaiwai, i ngā turanga kaha rānei.
Ngā tono
He whānuitia te whakamahinga o te PTFE kua whakapakarihia ki te GF i roto i ngā hiri waipēhi, ngā rango hau, me ngā gasket ahumahi, ā, ko te kaha ā-pūkaha me te whai huatanga o te utu te mea nui. Nā tōna hototahitanga ki ngā tāpiringa pēnei i te MoS₂ ka pai ake te whakahaere i te waku.
3. Muka Waro: Te Kōwhiringa Mahi-Tiketike
Ngā Āhuatanga Matua
Kaha me te Pakari: He pai ake te kaha kume me te āhua piko o te muka waro (CF), me iti ake ngā rahinga whakakī i te GF kia rite ai te whakakaha.
Te Arahi Wera: Ka whakapai ake te CF i te tohatoha wera, he mea nui mō ngā tono tere-tiketike.
Te Ātete Matū: Ka ātete te CF ki ngā waikawa kaha (haunga ngā mea whakahāwea) ā, he pai hoki mō ngā taiao matū uaua.
Ngā tono
He tino pai ngā rauemi hiato CF-PTFE mō ngā mea mimiti ru o ngā motuka, ngā taputapu haurua-ira, me ngā wāhanga rererangi, he mea nui te roa o te mama me te whakahaere wera.
4. Karāwhite: Te Tohunga Whakahinuhinu
Ngā Āhuatanga Matua
Te Waku Iti: Ka tutuki i te PTFE whakakīia ki te graphite ngā tauwehenga waku iti iho i te 0.02, ka whakaiti i te ngaronga pūngao i roto i ngā pūnaha hihiri.
Te Pūmautanga o te Wera: Ka whakarei ake te karāpiti i te kawe wera, ka ārai i te kohikohinga wera i roto i ngā hononga tere-rahi.
Hototahi Ngāwari: Ka whakaiti i te pakaru ki ngā mata ngohengohe pēnei i te konumohe, te parahi rānei.
Ngā tono
He pai ake ngā mea whakahiato kei roto i te karāpiti mō ngā peera kāore i whakahinuhinuhia, ngā hiri kōpeke, me ngā mīhini hurihuri ina he mea nui te maeneene o te mahi me te marara o te wera.
5. Tirohanga Whānui Whakataurite: Te Kōwhiri i te Whakakī Tika
| Momo Whakakī | Ātete Kakahu | Tauwehenga Waku | Te Arahi Wera | Pai rawa atu mō |
| muka karāhe | Teitei (500x te whakapainga) | Waenga | Waenga | Ngā hiri pūmau/hihiri e aro nui ana ki te utu, he nui te kawenga |
| muka waro | Tino Teitei | Iti ki te taurite | Teitei | Ngā taiao māmā, pāmahana teitei, me te waikura |
| Karāpiti | Waenga | Tino Iti (0.02) | Teitei | Ngā tono tere-teitei, kāore i te hinuhinuhia |
Ngā Ranunga Whakakotahi
Mā te whakakotahi i ngā whakakī—hei tauira, te muka karāhe me te MoS₂, te muka waro rānei me te karāpeti—ka taea te whakapai ake i ngā āhuatanga maha. Hei tauira, mā ngā ranu GF-MoS₂ ka whakaiti i te waku me te pupuri tonu i te ātete ki te kakahu.
6. Ngā Pānga ki te Ahumahi me te Oranga Tonu
Ka roa ake te roa o te ora o ngā wāhanga e ngā hiato PTFE kua whakakīia, ka whakaiti i te auau o te tiaki, ā, ka whakarei ake i te whai huatanga o te pūngao. Hei tauira, ka tu atu ngā hiri graphite-PTFE i roto i ngā pūnaha LNG i ngā pāmahana mai i te -180°C ki te +250°C, ka eke ki runga ake i ngā rauemi tuku iho. Ka hangai ēnei whanaketanga ki ngā whāinga ōhanga porowhita mā te whakaiti i te para mā te hoahoa pakari.
Whakamutunga
Ko te kōwhiringa o te whakakī—muka karāhe, muka waro, karāhe rānei—te mea e whakatau ana i te mahi a ngā hiato PTFE. Ahakoa he taurite te utu me te pakari o te muka karāhe, he pai te muka waro i ngā āhuatanga tino kino, ā, ko te karāhe te mea nui ki te whakahinuhinu. Mā te mārama ki ēnei rerekētanga ka taea e ngā kaihangarau te whakarite i ngā otinga hiri kia pono ai, kia whai hua ai hoki.
I te whanaketanga o ngā ahumahi ki ngā paerewa whakahaere teitei ake, mā te mahi tahi me ngā tohunga pūtaiao rauemi ka tino pai te whanaketanga o ngā hua. Ka whakamahia e te Ningbo Yokey Precision Technology ngā pūkenga whakahiato matatau hei tuku hiri e tutuki ai ngā whakaritenga pakari mō ngā tono motuka, pūngao, me ngā tono ahumahi.
