Ko te PTFE, te FEP me te PFA ngā mea tino rongonui, tino noa hoki o ngā kirihou fluoro. Engari he aha rawa ō rāua rerekētanga? Tirohia he aha ngā rauemi ahurei o ngā fluoropolymer, me tehea kirihou fluoro e tino pai ana mō tō tono.
Ngā āhuatanga ahurei o ngā kirihou fluoro
He maha ngā āhuatanga ahurei o ngā fluoropolymer e pai ai te whakamahi i roto i ngā mahi hauora, motuka, hiko me te whare, me ētahi atu.
Ko ngā āhuatanga o ngā kirihou fluoro:
1. Ngā pāmahana mahi tino teitei
2. Āhuatanga kore-piri
3. He iti te waku o te mata
4. He tino ātete ki ngā matū me ngā whakarewa
5. He tino teitei te ātete hiko
He rerekē ngā rerekētanga iti o ngā kirihou fluoro, tae atu ki ngā pāmahana mahi rerekē, ā, he pai mō ngā tono rerekē. Mēnā ka whiriwhiria tika, ka taea e ngā fluoropolymer te whakaputa i ngā painga utu pai me te mahi pai.
Ngā painga o te PTFE
PTFE, ko te Polytetrafluoroethylene rānei, te koroua o ngā kirihou fluoro katoa. I kitea e te kaipūtaiao a Roy J. Plunkett i te tau 1938, ko te PTFE te fluoropolymer tino rerekē, ā, e whakaatu ana i te mahi pai rawa atu i runga i te pāmahana, te ātete matū me ngā āhuatanga kore-piri.
Haunga ngā āhuatanga ahurei o ngā kirihou fluoro, he rerekē te PTFE mā te whai i ēnei painga e whai ake nei:
1. Utu pai rawa atu: ōwehenga mahi
2. Te pāmahana mahi tonu o te +260°C - Koinei te pāmahana mahi teitei rawa atu mō tetahi mea hanga ki te fluoroplastic
3. Ātete ki te nuinga o ngā matū
4. Tino kore-piri (tae atu ki te mokomoko ka paheke ki te PTFE)
5. Tae mārama
Ko te ngoikoretanga matua o te PTFE ko tōna kore e rewa ina werahia, nō reira he uaua ki te tukatuka. E hiahiatia ana ngā tikanga tino rerekē hei hanga, hei whakaputa me te whakarewa i tēnei fluoropolymer.
Nā ōna āhuatanga ahurei, he pai te PTFE mō ngā tono i roto i te whakamarumaru hiko me te tiaki i ngā wāhanga hiko.

Ngā painga o te FEP
Ko te FEP, ko te Fluoroethylenepropylene rānei, te putanga PTFE ka taea te tukatuka rewa. He tino rite ngā āhuatanga o te FEP ki te PTFE, engari he iti ake te pāmahana whakahaere mōrahi o te +200°C. Heoi, he māmā ake te tukatuka i te FEP, ā, he ngāwari te whakarewa me te hanga anō hei kōtaha uaua.
Haunga ngā āhuatanga ahurei o ngā kirihou fluoro, kei a FEP ēnei painga:
1. Te kaha ki te whakarewa me te hanga anō
2. Ngā pāmahana mahi whakahaere mai i te -200°C ki te +200°C - Ka noho ngāwari tonu te FEP i ngā pāmahana cryogenic
3. Ātete katoa ki ngā matū me te UV
4. Hototahi ki te koiora
5. Tae mārama
Nā ēnei painga, he iti te pāmahana whakaiti o te FEP he iti te pāmahana whakaiti, ā, ka taea te whakaiti haumaru i runga i ngā rauemi e pāngia ana e te pāmahana, me te kore e wehi kei pakaru. Nō reira, he pai te FEP mō te takai i ngā wāhanga hiko me ngā taputapu tairongo.
Ngā painga o te PFA
Ko te PFA, Perfluoralkoxy rānei, he putanga pāmahana teitei o te FEP. He rite ngā āhuatanga o te PFA ki te FEP engari ka taea te whakamahi i ngā pāmahana mahi tae atu ki te +260°C me te noho tonu ka taea te tukatuka rewa, nā te mea he iti ake te matotoru rewa i te PTFE.
Haunga te pārekareka ki ngā āhuatanga ahurei o ngā fluoropolymers, ka wehewehea te PFA mā te whai i ēnei painga e whai ake nei:
Te pāmahana mahi tonu o te +260°C - Koinei te pāmahana mahi teitei rawa atu mō tetahi mea hanga-pūoro
1. Te kaha ki te whakarewa me te hanga anō
2. Ātete uruhanga pai
3. Ātete matū tino pai, ahakoa i ngā pāmahana teitei
4. Hototahi ki te koiora
5. Ngā māka parakore teitei e wātea ana
6. Tae mārama
Ko te ngoikoretanga matua o te PFA he nui ake te utu i te PTFE me te FEP.
He pai rawa te PFA mō ngā tono e hiahia ana kia teitei ake te parakore, kia pai te ātete matū me te pāmahana mahi teitei. He whānuitia te whakamahinga o tēnei kirihou fluoro i roto i ngā ngongo hauora, ngā whakawhiti wera, ngā kete haurua-arataki, ngā papu me ngā hononga, me ngā arai takirere.
