Polytetrafluoroethylene (PTFE) he fluoropolymer synthetic o ka tetrafluoroethylene he nui nā noi.ʻO ka inoa inoa kaulana loa oPTFE-ma muli o…
ʻO PolyTetraFluoroEthylene kahi polymer ma muli o ka fluorocarbon a ua hoʻopau pinepine ʻia ʻo PTFE.Hana kekahi mau mea hana ʻē aʻe i kā lākou mau inoa ponoʻī o PTFE i hiki ke hoʻohana pinepine ʻia i mau mea pani.Hāʻawi kēia ʻohana fluoroplastic i ke kūpaʻa kemika kiʻekiʻe, ka haʻahaʻa a me ke kiʻekiʻe o ka wela, ke kūʻē i ka wā, ka haʻahaʻa haʻahaʻa, ka uila a me ka wela wela, a me ka "pahee".(e nānā pū i ka polymer® PTFE a mepolimer® FEP & PFA Specifications ) He haʻahaʻa nā waiwai mechanical o PTFE i hoʻohālikelike ʻia me nā plastics ʻē aʻe, akā mau kona mau waiwai ma kahi pae kūpono ma luna o kahi ākea ākea o -100°F a +400°F (-73°C a 204°C) .Hoʻonui pinepine ʻia nā waiwai mīkini ma ka hoʻohui ʻana i nā mea hoʻopihapiha (e ʻike i ka paukū ma lalo).Loaʻa iā ia nā waiwai insulation wela a me ka uila a me ka coefficient haʻahaʻa o ka friction.ʻOkoʻo loa ka PTFE a ʻaʻole hiki ke hoʻoheheʻe ʻia - pono e hoʻopili ʻia a hoʻopaʻa ʻia e hana i nā ʻano kūpono.
Hiki ke hoʻonui ʻia nā waiwai mechanical o PTFE ma o ka hoʻohui ʻana i nā mea hoʻopihapiha e like me ke aniani fibers, carbon, graphite, molybdenum disulphide, a me ke keleawe.ʻO ka mea maʻamau, hoʻopiha ʻia ka PTFE i kā lākou kemika maikaʻi a me nā ʻano wela kiʻekiʻe, ʻoiai nā mea hoʻopihapiha e hoʻomaikaʻi i ka ikaika mechanical, kūpaʻa, a me ke kūpaʻa ʻana.Hōʻike ʻia nā waiwai o 25% piha aniani a me 25% carbon-filled PTFE māka ma lalo no nā kumu hoʻohālikelike.He nui maoli nā huahana PTFE piha piha a me nā māka - he nui loa e helu ʻia ma aneʻi.
NA WAIWAI MAU o PTFE
NĀ MEA: ʻO ka ʻike i loko nei he mau waiwai maʻamau i manaʻo ʻia no ka hoʻohālikelike a me nā kumu hoʻohālikelike wale nō.ʻAʻole pono lākou e hoʻohana ʻia i kumu no nā kikoʻī hoʻolālā a i ʻole ka mana o ka maikaʻi.E hoʻokaʻaʻike mai iā mākou no ka ʻikepili waiwai piha o nā mea hana.ʻO nā waiwai a pau ma 73°F (23°C) ke ʻole i ʻike ʻia.
