ʻO nā ʻano huahana PTFE āpau i hana koʻikoʻi i ka ʻoihana hoʻokele aupuni e like me ka ʻoihana kemika, nā mīkini, nā uila, nā mea uila, ka ʻoihana koa, ka aerospace, ka palekana o ke kaiapuni a me nā alahaka.
He kūpono ka papa Tetrafluoroethylene no ka mahana o -180 ℃ ~ + 250 ℃.Hoʻohana nui ʻia ʻo ia e like me nā mea insulation uila a me nā linings no ka hoʻopili ʻana me nā media corrosive, kākoʻo i nā sliders, nā sila rail a me nā mea lubricating.Hoʻohana ʻia ia i ka ʻoihana māmā e nā lako keʻena waiwai., Hoʻohana nui ʻia i loko o nā kemika, lāʻau lapaʻau, nā ipu ʻoihana wai, nā pahu mālama, nā kīʻaha hale kiaʻi pane, nā mea pale anti-corrosion no nā paipu nui;mokulele, koa a me nā ʻoihana kaumaha ʻē aʻe;nā mīkini, ka hana, nā alahaka paheʻe, nā ala alakaʻi;paʻi a hoʻoluʻu, ʻoihana māmā, textiles Nā mea kūʻē i ka paʻa ʻana o ka ʻoihana, etc.

Kūleʻa wela kiʻekiʻe - hiki i ka mahana hana ke hiki i 250 ° C.
ʻO ke kūpaʻa haʻahaʻa haʻahaʻa - loaʻa ka paʻakikī mechanical maikaʻi;ʻoiai inā hāʻule ka mahana i -196 ° C, hiki iā ia ke mālama i kahi elongation o 5%.
Ka pale ʻana i ka corrosion - inert i ka hapa nui o nā kemika a me nā mea hoʻoheheʻe, kūpaʻa i nā ʻakika ikaika a me nā alkalis, ka wai a me nā mea hoʻoheheʻe organik like ʻole.
Kūleʻa i ka wā - ʻoi aku ka maikaʻi o ke ola ʻelemakule ma waena o nā plastics.
Lubrication kiʻekiʻe - ka helu haʻahaʻa o ka friction ma waena o nā mea paʻa.
Non-adhesion - ʻo ia ka liʻiliʻi liʻiliʻi o ka ʻili ma waena o nā mea paʻa, ʻaʻole pili i kekahi mea, a ʻo kona mau waiwai mechanical he liʻiliʻi liʻiliʻi liʻiliʻi loa, ʻo ia wale nō ka 1/5 o ka polyethylene, kahi hiʻohiʻona nui o ka perfluorocarbon. nā ʻili.A ma muli o ka ikaika intermolecular haʻahaʻa loa o nā kaulahao fluorine-carbon, ʻaʻole pili ka PTFE.
ʻAʻohe mea ʻawaʻawa - he physiologically inert a ʻaʻohe hopena ʻino ke hoʻokomo ʻia i loko o ke kino ma ke ʻano he kīʻaha koko a me ke kino no ka manawa lōʻihi.
Uila waiwai PTFE i haʻahaʻa dielectric mau a me ka dielectric poho i loko o ka laulā alapine (frequency), a kiʻekiʻe breakdown voltage, leo resistivity a me ka arc kū'ē.
Ka pale ʻana i ka hoʻoheheʻe ʻana ʻAʻole maikaʻi ka pale radiation o polytetrafluoroethylene (104 rads), a ua hoʻohaʻahaʻa ʻia e ka pāhawewe ikehu kiʻekiʻe, a ua hoʻemi nui ʻia nā waiwai uila a me nā mīkini o ka polymer.Hiki ke hana ʻia ka palapala noi PTFE e ka hoʻoemi a extrusion paha;hiki ke hana ʻia i mea hoʻopuehu wai no ka uhi ʻana, impregnation a i ʻole ka hana ʻana i nā fiber.Hoʻohana nui ʻia ka PTFE e like me ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa wela, corrosion resistant material, insulating material, anti-stick coatings, etc. nā ʻoihana.
ʻO ke kūpaʻa kahiko o ka lewa: ka pale ʻana i ka radiation a me ka haʻahaʻa haʻahaʻa: ʻike lōʻihi i ka lewa, ʻaʻole i loli ka ʻili a me ka hana.
Non-combustibility: Aia ma lalo o 90 ka helu helu oxygen palena.
ʻAkika a me ke kūpaʻa alkali: hiki ʻole ke hoʻoheheʻe ʻia i ka waikawa ikaika, ka alkali ikaika a me ka mea hoʻoheheʻe organik.
Palekana oxidation: Hiki iā ia ke pale i ka corrosion o nā oxidants ikaika.
Acidity a me ka alkalinity: kū ʻole.
He palupalu nā mea mechanical o PTFE.Loaʻa i ka ikehu ili haʻahaʻa loa.
ʻO ka Polytetrafluoroethylene (F4, PTFE) he mau hana maikaʻi loa: ke kūʻokoʻa kiʻekiʻe - ka mahana hoʻohana lōʻihi 200 ~ 260 degere, haʻahaʻa haʻahaʻa haʻahaʻa - palupalu mau ma -100 degere;kū'ē i ka corrosion - kū'ē i ka aqua regia a me nā mea hoʻoheheʻe organik a pau;ʻO ke kūpaʻa ʻana i ka wā—ke ola ʻelemakule maikaʻi loa ma waena o nā plastics;ka lubricity kiʻekiʻe—ʻo ka helu liʻiliʻi loa o ka friction (0.04) ma waena o nā plastics;lāʻau ʻole—ʻo ka haʻalulu liʻiliʻi loa ma waena o nā mea paʻa me ka pipili ʻole i kekahi mea;non-toxic—physiologically inert;ʻO nā waiwai uila maikaʻi, ʻo ia kahi mea insulating Class C.
