Nā pono o ka PTFE

ʻEwalu mau pono o ka PTFE:
Hoʻokahi: Loaʻa i ka PTFE ka waiwai o ke kūpaʻa wela kiʻekiʻe, hiki i kona hoʻohana ʻana i ka mahana ke hiki i 250 ℃, i ka wā e piʻi ai ka mahana plastic maʻamau i 100 ℃, e hoʻoheheʻe ka plastic iā ia iho, akā i ka hiki ʻana o ka tetrafluoroethylene i 250 ℃, hiki iā ia ke mālama i ke ʻano holoʻokoʻa. ʻAʻole ia e loli, a ʻoiai ke piʻi ka mahana i 300 °C i ka manawa koke, ʻaʻohe loli i ke ʻano kino.
ʻElua: PTFE kekahi waiwai kūʻē, ʻo ia hoʻi, haʻahaʻa haʻahaʻa haʻahaʻa, ke hāʻule ka haʻahaʻa haʻahaʻa i -190 ° C, hiki iā ia ke mālama i ka 5% elongation.
Ekolu: PTFE i corrosion-kū'ē waiwai.No ka hapa nui o nā kemika a me nā mea hoʻoheheʻe, hōʻike ia i ka inertness a hiki ke kū i nā waikawa ikaika a me nā alkalis, ka wai a me nā mea hoʻoheheʻe kūlohelohe.
ʻEhā: Loaʻa i ka PTFE nā waiwai o ka pale ʻana i ka wā.ʻAʻole komo ka PTFE i ka makū a ʻaʻole hiki ke puhi ʻia, a paʻa loa ia i ka oxygen a me nā kukui ultraviolet, no laila ʻoi aku ka maikaʻi o ke ola ʻelemakule ma nā plastics.
Elima: PTFE i kiʻekiʻe lubricating waiwai, a me ka PTFE mea laumania i hiki ole ke hoohalike me ka hau, no laila, i ka haʻahaʻa friction coefficient i waena o nā mea paʻa.
ʻEono: Loaʻa i ka PTFE ka waiwai o ka pili ʻole.No ka haʻahaʻa loa o ka ikaika intermolecular o ke kaulahao oxygen-carbon, ʻaʻole ia e pili i kekahi mea.
ʻEhiku: Loaʻa i ka PTFE nā waiwai ʻole, no laila hoʻohana mau ʻia i ka lāʻau lapaʻau, e like me nā kīʻaha koko artificial, extracorporeal circulators, rhinoplasty, a me nā mea ʻē aʻe, ma ke ʻano he okana no ka implantation lōʻihi i loko o ke kino me ka ʻole o nā hopena ʻino.
ʻEwalu: Loaʻa i ka PTFE ka waiwai o ka insulation uila, hiki iā ia ke pale aku i ka 1500 volts o ka uila kiʻekiʻe.
