Te Tukatuka me ngā Taupānga PTFE

He aha te meaPTFE?

Me tīmata tā tātou tūhuratanga mō te PTFE. Hei whakamārama i tōna ingoa katoa, ko te polytetrafluoroethylene he pūhui hangai e rua ngā huānga māmā; te waro me te fluorine. I ahu mai i te tetrafluoroethylene (TFE) ā, he āhuatanga ahurei tōna e whai hua ai i roto i te whānuitanga o ngā tono. Hei tauira:

Teitei rawa te ira rewa: I te mea he tata ki te 327°C te ira rewa, he iti noa ngā wā ka pakaru te PTFE i te wera.

Ātete wai: Nā te ātete ki te wai, kāore e mākū, he mea whai hua mō te tunu kai, mō te takai patunga me te maha atu.

Kāore e mahi matū: Ko te nuinga o ngā whakarewa me ngā matū kāore e kino ki te PTFE.

Te iti o te tauwehenga waku: Ko te iti rawa o te tauwehenga waku o te PTFE o ngā totoka katoa e ora ana, arā, kāore he mea e piri ki a ia.

Kaha piko teitei: Nā tōna kaha ki te piko me te piko, ahakoa i ngā pāmahana iti, ka taea te whakamahi ngāwari ki ngā momo mata me te kore e ngaro tōna āhua pai.

Te tukatuka o te PTFE

Ka kitea te PTFE i roto i ngā āhua porotaka, marara me te paura pai. He teitei te pāmahana rewa me te matotoru rewa o te PTFE haurua-kiriata, ā, he uaua te hanga i te whakaputanga me te werohanga. Nō reira, he rite ake te tukatuka PTFE ki te tukatuka paura i tērā o ngā kirihou tuku iho.

Ka hangaia te PTFE kirikiri i roto i te tauhohenga whakapūhui wai-whakarewa. Ko te kapia kirikiri ka puta mai ka tukatukahia kia āhua mā te whakakōpeketanga. Ka hangaia ngā hua marara PTFE i roto i te huarahi ōrite, me te tāpiri i ngā kaihoko marara. Ka taea te whakamahi i ngā hua marara mō ngā paninga PTFE, ka taea rānei te tukatuka hei kiriata angiangi mā te whakarewa kiriata. Ka hangaia te paura PTFE i roto i te tauhohenga whakapūhui emulsion. Ka taea te whakapiri i te paura pai ka puta mai ki roto i ngā rīpene PTFE, ngā ngongo PTFE, me te whakamahana waea, ka whakamahia rānei hei tāpiri hei whakanui ake i te ātete waikura i roto i ētahi atu rauemi kirihou.

Ngā Whakamahinga Matua e 5 o te PTFE

1. Te whakamahi i ngā āhuatanga ārai-waikura

Kāore te rapa, te karāhe, te whakarewa me ētahi atu rauemi e tutuki i ngā āhuatanga uaua o te pāmahana, te pēhanga me te taiao matū noho tahi nā ō rātou ngoikoretanga o te ātete ki te waikura. Heoi, he tino pai te ātete ki te waikura o te PTFE, nō reira kua noho hei rauemi ātete ki te waikura matua mō te hinu, te matū, te kakahu me ētahi atu ahumahi.

2. Te whakamahinga o ngā āhuatanga waku iti i roto i te kawenga

Kāore e pai te whakahinuhinu hinu mō ngā wāhanga waku o ētahi taputapu, nā te mea ka taea te whakarewa i te hinu e ngā whakarewa, ā, kāore e mahi, me karo rānei ngā hua i roto i ngā mara rongoā, kai, kakahu me ētahi atu mara ahumahi i te poke i ngā hinu. Nō reira, ko te kirihou PTFE, he iti iho tōna tauwehenga waku i tētahi atu rauemi totoka e mōhiotia ana, kua noho hei rauemi tino pai mō te whakahinuhinu kore-hinu (te kawe kawenga tika) o ngā wāhanga taputapu miihini.

3. Te tono i roto i te hiko me te hikohiko

Nā te iti o te ngaronga ā-roto me te iti o te pūmau dielectric o te rauemi PTFE ka taea te hanga hei waea enamel mō ngā mota moroiti, ngā thermocouples me ngā taputapu whakahaere. Ko te kiriata PTFE te rauemi whakamarumaru pai mō te hanga pūnga hiko, te raina whakamarumaru reo irirangi, ngā taura whakamarumaru, ngā mota me ngā whakawhiti hiko, ā, ko tētahi o ngā rauemi tino nui mō te rererangi me ētahi atu wāhanga hiko ahumahi.

4. Te whakamahinga i roto i te rongoā hauora

He koretake noa iho te PTFE kua whakawhanuitia, ā, he tino urutau ki te koiora, nō reira kāore e pāngia e te tinana, kāore he pānga taha ā-tinana ki te tinana tangata, ka taea te whakahoromata mā tetahi tikanga, ā, he maha ngā moroiti-pūngao tōna hanganga.

5. Te whakamahi i ngā āhuatanga ārai-piripiri

Nā te iti rawa o te kukū o te mata o tētahi rauemi totoka, kāore te PTFE Teflon e piri ki tētahi mea. Heoi anō, he tino pai tōna ātete ki ngā pāmahana teitei me ngā pāmahana iti. Nō reira, kua whānuitia te whakamahinga i roto i te āhuatanga ārai-piri o ngā paraharaha kore-piri.
