PTFEhe paʻa fluorocarbon, no ka mea, he pūhui kiʻekiʻe-molekala-kaumaha i loko o ke kalapona a me ka fluorine.He hydrophobic ka PTFE: ʻaʻole wai ka wai a ʻaʻole wai ka wai i ka PTFE, ʻoiai e hōʻike ana nā fluorocarbons i nā ikaika hoʻopuehu London ma muli o ke kiʻekiʻe electronegativity o ka fluorine.ʻO ka PTFE kekahi o nā coefficient haʻahaʻa loa o ka friction o kekahi paʻa.
ʻO ka PTFE kahi mea maʻalahi i loaʻa i nā noi niche he nui:
Loaʻa pinepine ʻia i loko o nā paʻa ski ma ke ʻano he AFD non-mechanical (Anti-Friction Device)
Hiki ke kikoo 'ia no ka loa'a 'ana o nā pores li'ili'i o nā 'ano like 'ole a waiho 'ia ma waena o nā papa lole no ka hana 'ana i ka lole hanu a me ka wai i loko o nā lole waho.
Hoʻohana nui ʻia ʻo ia ma ke ʻano he pale lole no ka hoʻokuʻu ʻana i nā ʻili ma nā lole kula maʻamau, e like me nā blazers ʻaʻahu.
Hoʻohana ʻia ia ma ke ʻano he kiʻi kiʻiʻoniʻoni no nā haʻuki a me nā noi lapaʻau, e hōʻike ana i kahi kākoʻo paʻa paʻa paʻa, i hoʻokomo ʻia i nā wahi friction kiʻekiʻe o nā kāmaʻa, insoles, ankle-foot orthosis, a me nā mea lapaʻau ʻē aʻe e pale a hoʻomaha i ka friction- i hoʻoulu ʻia i nā ʻōpala, nā calluses a me ka ʻeha wāwae.
Ua hoʻohana ʻia nā membrane PTFE i hoʻonui ʻia i nā hoʻāʻo e kōkua i ke ʻoki trabeculectomy e mālama i ka glaucoma.
Hoʻohana ʻia ka PTFE pauka i nā haku mele pyrotechnic ma ke ʻano he oxidizer me nā metala pauka e like me ka aluminika a me ka magnesium.Ke hoʻā ʻia, hana kēia mau hui ʻana i ka soot carbonaceous a me ka fluoride metala pili, a hoʻokuʻu i ka nui o ka wela.Hoʻohana ʻia ia mau mea i loko o ka infrared decoy flares a ma ke ʻano he igniters no nā mea hoʻolale pōhaku paʻa.
Hoʻohana ʻia ka PTFE pauka i ka hoʻokuʻu ʻia me kahi haʻahaʻa haʻahaʻa, azeotropic hui ʻana o siloxane ethers e hana i kahi lubricant no ka hoʻohana ʻana i nā puʻupuʻu twisty.
Ma ka radiometry optical, hoʻohana ʻia nā ʻāpana o ka PTFE e like me ke ana ʻana i nā poʻo i nā spectroradiometers a me nā radiometers broadband (e laʻa, nā mika kukui a me nā radiometer UV) ma muli o ka hiki o PTFE ke hoʻopuehu i kahi kukui hoʻouna kokoke loa.Eia kekahi, noho mau nā waiwai optical o PTFE ma luna o kahi ākea o nā nalu nalu, mai UV a hiki i ka infrared kokoke.Ma kēia ʻāpana, ʻaʻole liʻiliʻi ka pilina o kāna transmittance maʻamau i ka diffuse transmittance, no laila e hoʻomālamalama ʻia ka mālamalama ma o ka diffuser (PTFE sheet) e like me ke kānāwai cosine a Lambert.Pela ka PTFE e hiki ai i ka pane angular cosinusoidal no ka mea ike e ana i ka mana o ka hoolele opua ma ka ili, e la'a me ke ana o ka la.
Hoʻopili ʻia kekahi mau ʻano pōkā me ka PTFE e hōʻemi i ka ʻaʻahu ʻana i ka puhi ʻana o nā pū i hoʻokumu ʻia e nā projectiles i uhi ʻole ʻia.ʻAʻole hāʻawi ʻo PTFE iā ia iho i kahi projectile kahi waiwai hoʻopaʻa kaua.
ʻO kona kūpaʻa corrosion kiʻekiʻe e hoʻohana pono ai ka PTFE i nā kaiapuni keʻena, kahi i hoʻohana ʻia no nā ipu lining, ma ke ʻano he uhi no nā mea hoʻoheheʻe magnetic, a ma ke ʻano he paipu no nā kemika nui loa e like me ka waika hydrofluoric, e hoʻoheheʻe i nā ipu aniani.Hoʻohana ʻia ia i loko o nā pahu no ka mālama ʻana i ka waika fluoroantimonic, kahi superacid.
Hoʻohana ʻia nā paipu PTFE i nā mea hoʻololi wela kinoea i ka hoʻomaʻemaʻe kinoea o nā ʻōpala ʻōpala.He mau megawatts ka nui o ka mana mana.
Hoʻohana nui ʻia ʻo PTFE ma ke ʻano he lipine seal thread i nā noi plumbing, ka mea nui e hoʻololi i ka dope thread paste.
ʻO nā kānana membrane PTFE kekahi o nā kānana ea ʻoihana maikaʻi loa.Hoʻohana pinepine ʻia nā kānana i uhi ʻia i ka PTFE i nā ʻōnaehana ohi lepo e hōʻiliʻili i nā mea ʻala mai nā kahawai ea i nā noi e pili ana i nā wela kiʻekiʻe a me nā haʻahaʻa haʻahaʻa kiʻekiʻe e like me nā mea kanu mana ahi, hana sima a me nā mea hao.
Hiki ke hoʻohana ʻia nā grafts PTFE e kāʻalo i nā ʻaʻa stenotic i ka maʻi vascular peripheral inā ʻaʻole i loaʻa kahi kāpili vein autologous kūpono.
Nui nā lubricants a me nā momona i loaʻa i ka PTFE a hoʻohana ʻia ma nā kaulahao a me nā ʻāpana ʻē aʻe i hoʻopili ʻia i nā mana frictional (e like me nā bearings hub).
Hiki ke hoʻohana ʻia ka PTFE no ka hoʻopiha ʻana i nā niho, e hoʻokaʻawale i nā pilina o ka niho mua i ʻole e pili nā mea hoʻopiha i ka niho pili.
Hoʻohana ʻia nā pepa PTFE i ka hana ʻana i ka aila hash butane ma muli o kāna mau waiwai non-stick a me ke kūʻē ʻana i nā solvents non-polar.
ʻO ka PTFE, pili me kahi laminate kikokikona liʻiliʻi, hana i ka ʻōnaehana haʻi maʻamau o kahi telescope Dobsonian.
Hoʻohana nui ʻia ʻo PTFE ma ke ʻano he lāʻau lāʻau ʻole no nā mea hana meaʻai;ʻo nā kīʻaha palaoa, nā kīʻaha hui, nā ʻōnaehana conveyor, nā wili, a me nā chutes.Hiki ke hoʻoikaika ʻia ka PTFE ma kahi e loaʻa ai ka abrasion - no ka hoʻoponopono ʻana i nā mea hana i kanu ʻia a i ʻole ka palaoa palaoa.
