ʻO ka uhi kūikawā Teflon kiʻekiʻeptfee like me ka resin kumu o ka fluorine uhi, English inoa no Teflon, no ka pronunciation, maʻamau no hoi i ike like me Teflon, Teflon, Teflon, Teflon a pela aku (no ka unuhi o Teflon).

Ua māhele ʻia ʻo Teflon i PTFE, FEP, PFA, ETFE kekahi mau ʻano kumu: TEflon PTFE: PTFE (polytetrafluoron) hiki ke hoʻohana mau ʻia i ka 260 deG C, me ka wela hoʻohana kiʻekiʻe o 290-300 DEG C, haʻahaʻa haʻahaʻa. coefficient, pale lole maikaʻi a me ke kūpaʻa kemika maikaʻi loa. Teflon FEP: FEP (fluorinated ethylene propylene copolymer) non-stick coating hehee i ka wā o ka kuke ʻana e hana i kahi kiʻiʻoniʻoni porous, me ka paʻa kemika maikaʻi loa, nā waiwai non-stick maikaʻi loa, ʻo ka mahana hana kiʻekiʻe he 200 ℃. ʻO Teflon PFA: PFA (perfluoroalkyl) ʻaʻahu lāʻau ʻole, e like me FEP, hoʻoheheʻe ʻia i ka wā e kuke ai e hana i kahi kiʻiʻoniʻoni porous. ʻO nā mea maikaʻi o ka PFA ʻoi aku ka kiʻekiʻe o ka hoʻohana ʻana i ka mahana o 260 ℃, ʻoi aku ka ikaika o ka paʻakikī, kūpono loa no ka hoʻohana ʻana i ke kiʻekiʻe kiʻekiʻe ma lalo o ke kumu o ka anti-stick a me ke kūpaʻa kemika ma ke kahua o ka hoʻohana. Teflon ETFE: ʻO ETFE kahi copolymer o ka ethylene a me ka tetrafluoroethylene. ʻO ka resin ka fluoropolymer paʻakikī, e hana ana i kahi uhi paʻa loa me ke kūpaʻa kemika maikaʻi loa i ka hana mau ma 150 ° C.

Ma hope o ka uhi ʻia ʻana me Teflon, loaʻa iā ia nā ʻano aʻe:

1, non-viscosity: ʻaneʻane ʻaʻole i hoʻopaʻa ʻia nā mea āpau me ka kiʻiʻoniʻoni teflon. Hōʻike pū nā membrane lahilahi loa i nā waiwai non-adhesion maikaʻi.

2, pale wela: ʻO ke kiʻi ʻoniʻoni ʻo Teflon maikaʻi loa ka pale wela a me ka haʻahaʻa haʻahaʻa. Hiki i ka manawa pōkole ke pale i ka wela kiʻekiʻe a hiki i 300 ℃, ma waena o 240 ℃ ~ 260 ℃ hiki ke hoʻohana mau ʻia, me ka ʻike ʻole o ka wela, hiki ke hana i ka mahana maloʻo me ka ʻole o ka embrittlement, ʻaʻole hehee i ka wela kiʻekiʻe.

3, sliding: ʻO ke kiʻi ʻoniʻoni Teflon he haʻahaʻa haʻahaʻa o ka friction. I ka paheʻe ʻana o ka ukana, hoʻololi ke koena friction, akā aia ka waiwai ma waena o 0.05 a me 0.15 wale nō.

4, pale ʻana i ka wai: ʻaʻole pili ka ʻili kiʻi teflon i ka wai a me ka aila, ʻaʻole maʻalahi ka mana o ka hana e hoʻopili i ka hopena, e like me ka liʻiliʻi o ka lepo, hiki ke wehe ʻia ka holoi maʻalahi. ʻO ka manawa haʻahaʻa pōkole, mālama i ka manawa a hoʻomaikaʻi i ka pono hana.

5, ʻaʻahu kūʻē: ma lalo o ka ukana kiʻekiʻe, me ka hana maikaʻi ʻoi aku ka pale ʻana. Ma lalo o kekahi ukana, loaʻa iā ia nā pono ʻelua o ka pale ʻana a me ka hoʻopili ʻole.

6. Ke kū'ē i ka corrosion: ʻaneʻane kūʻē ʻo Teflon i ka lāʻau ʻino a hiki ke pale i nā ʻāpana mai nā ʻano ʻino kemika.
