He tino āta haere te whanaketanga o te Polytetrafluoroethylene (PTFE) – mai i tētahi hua motuhake e whakamahia ana mō ngā tono utu nui anake ki tētahi whakaritenga whānui.
Heoi, i roto i ngā tekau tau e rua kua pahure ake nei, te āhua nei kua eke te whakamahinga o te PTFE ki tētahi taumata teitei rawa atu, ā, kua taea ai te whakamahi i roto i ngā tono ahumahi, kaihoko me te hauora neke atu i te 200. Ahakoa ko ngā pepa, ngā tokotoko, ngā paninga me ngā wāhanga te nuinga o te mākete mō ngā hua PTFE, kei te puta ake ngā ngongo PTFE me ngā ngongo PTFE hei wāhanga tipu matua.
Ngā tono ngongo PTFE
Te whakamahinga oNgongo PTFEKua horapa puta noa i ngā tono maha tae atu ki te motuka, te matū, te hiko me te hauora. E whakaatu ana te Ripanga 1 i ngā āhuatanga matua e whakaatu ana i te maha o ngā whakamahinga o te ngongo PTFE, ā, e whakaatu ana te Pikitia 1 i ōna whakamahinga i roto i ngā mara maha.
I roto i ngā tono motuka, nā te kaha o te PTFE ki te tu atu i ngā pāmahana neke atu i te 250°C, he mea tino pai mō te whakawhiti wai pāmahana teitei.
I roto i ngā tono hauora,Ngongo PTFEHe nui te hiahia mō tēnei mea nā tōna kaha ki te whakahinuhinu me te kore e taea te whakamahi i ngā matū. Ka taea te whakauru i ngā katita e whakamahi ana i te ngongo PTFE ki roto i te tinana tangata, me te kore e mataku kei pāngia tetahi wāhanga o te tinana e te tauhohenga, te pakaru rānei.
I roto i ngā whakamahinga matū – tae atu ki ngā taiwhanga – he whakakapinga pai te PTFE mō te karāhe nā tōna koretake me tōna pakari.
I roto i ngā tono hiko, nā ngā āhuatanga uruhanga pai rawa atu o te PTFE tauhou he mea tino pai mō te ārai i ngā taura ngaohiko teitei.
Ngā momo ngongo PTFE
I runga i te whakamahinga, ka wehea te ngongo PTFE kia toru ngā wāhanga whānui – ia wāhanga e tautuhia ana e te whānui o te ngongo me te matotoru o te pakitara (tirohia te Ripanga 2).
Ahakoa i roto i ngā kāwai, he rerekē ngā momo rerekētanga o te ngongo PTFE, ā, he rerekē te whakamahinga o ia kāwai (tirohia te Ripanga 3):
Ngā ngongo PTFE i roto i te mākete taputapu hauora
I te nuinga o te wā, ka whakamahia te ngongo spaghetti diameter iti i roto i ngā mahi hauora. Ko te whakamahinga o te PTFE i tēnei wāhanga e aro ana ki ngā āhuatanga matua e rua: te whakahinuhinu me te hototahitanga koiora. He tino pai te whakahinuhinu o ngā fluoropolymers ki te whakataurite ki ētahi atu kirihou. Ko te PTFE te polymer tino whakahinuhinu e wātea ana, me te tauwehenga waku o te 0.1, ā, ko te fluorinated ethylene propylene (FEP) e whai ake nei, me te 0.2. Ko ēnei polymer e rua te nuinga o ngā ngongo fluoropolymer katoa e whakamahia ana i roto i ngā taputapu hauora.
He mea nui te hototahitanga koiora o tētahi pūmua e whakamahia ana i roto i tētahi taputapu hauora. He tino pai te PTFE i tēnei wāhanga, ā, kua roa nei e whakamahia ana i roto i te tinana ora. Me tutuki i ngā pūmua fluoro-hauora ngā whakaritenga whakamātautau USP Class VI me te ISO 10993. He mea nui anō hoki te ma o te tukatuka.
I roto i ngā tau 18 kua pahure ake nei, kei te arotahi tonu a Besteflon ki te hanga i ngā Ngongo PTFE me ngā ngongo PTFE. Hei paionia i roto i te ao hanga kirihou fluoro, ka whai mātou i te kounga pai rawa atu me te ratonga muri-hoko. Mena kei te hiahia koe ki te tīmata ki te whakarite i ngā ngongo PTFE mō tō tono motuhake, tēnā koa whakapā mai!
