ʻO PTFE Molecular Structure a me kona mau waiwai maikaʻi loa

Ma keʻano he mea hana kumu kumu o ka PTFE kiʻekiʻe-mehana lole, Jiangsu Aokai New Materials e lawe mai iā ʻoe i nā ʻike ʻoihana. ʻO ka mea nui o ka PTFE kiʻekiʻe-mehana lole ʻo Polytetrafluoroethylene (PTFE), me ke ʻano mole o (mathbf{-(CF_2-CF_2)_n-}). Hoʻopili piha ʻia ke kaulahao nui kalapona e nā ʻātoma fluorine. ʻO kēia mau waiwai kiʻekiʻe ʻekolu e pili ana i nā hiʻohiʻona o nā molekala PTFE ma nā pae like ʻole:

1. Ka waiwai non-stick maikaʻi loa

Loaʻa ʻia mai ka ikehu ʻili haʻahaʻa haʻahaʻa, hoʻoholo ʻia e ka uhi ʻana i waho o nā ʻātoma fluorine  a me ka non-polarity molekula..

·  Ka hopena pale kiʻekiʻe o nā ʻātoma fluorine: Loaʻa iā Fluorine ka electronegativity ikaika loa a me kahi radius van der Waals nui. Hoʻonohonoho mau ʻia a paʻa loa i loko o kahi ʻōniʻoniʻo ma ka ʻaoʻao o waho o ke kaulahao kalapona, hana ʻia nā ʻātoma fluorine i kahi pūpū pale paʻa a hana i kahi ʻili laulima fluorinated piha.

·  Nawaliwali ka ikaika intermolecular: ʻOiai ʻo ka paʻa CF he polar ikaika, ʻo ka hoʻonohonoho symmetrical piha e hoʻolilo i ke kaulahao molekala holoʻokoʻa ʻole polar. ʻO nā pūʻali hoʻopuehu nāwaliwali wale nō i loaʻa ma waena o nā molekala, e hopena i kahi ikehu haʻahaʻa haʻahaʻa loa (ma kahi o 18 mN/m). Aneane ʻaʻohe mea hiki ke hoʻolaha a pili i ka ʻili PTFE.

2. Akika ikaika & Alkali Corrosion Kū'ē

Loaʻa mai ka inertness paʻa kemika kiʻekiʻe loa, i hoʻoholo ʻia e ka ikehu paʻa CF kiʻekiʻe  a me ka hopena pale pale steric.

·  ʻO nā paʻa CF ikaika kiʻekiʻe: ʻO ka mea paʻa CF e hōʻike ana i ka ikehu hoʻopaʻa kiʻekiʻe loa (ma kahi o 485 kJ/mol), ʻoi aku ka paʻa ma mua o nā paʻa CH a me CC, a paʻakikī loa e wāwahi.

·  Paʻa pale pale piha: Hoʻopili piha ka pūpū fluorine atom i ka iwi kaula kalapona, e pale ana i nā ion corrosive mai ka hoʻopili ʻana i ke kaulahao kalapona hiki ke hoʻopaʻa ʻia. Hoʻomaopopo ia i ka pale kino kino a me ke kemika.

3. ʻOi aku ka maikaʻi o ka uila uila

Loaʻa ʻia mai ka polarizability haʻahaʻa loa a me nā uku manuahi ʻole, i hoʻoholo ʻia e ka molecular symmetry  a me ka hopena paʻa electron ikaika..

·  Integral non-polar hale: Me ka kūloko polarity o CF paa, ka piha symmetrical hoʻonohonoho o fluorine nā mana ma nā ʻaoʻao ʻelua o ke kalapona kalapona hopena i ka aneane ʻole ka huina molecular dipole manawa, e hana ana i ka PTFE i mea maʻamau non-polar.

·  Nā electron paʻa paʻa: ʻO ka electronegativity ikaika o nā ʻātoma fluorine e huki paʻa i nā ao uila i nā ʻātoma fluorine. ʻAʻole hiki ke neʻe a hoʻomaha paha nā electrons i loko o nā molekala ma lalo o ke kahua uila waho, me ka nele o nā mea lawe hoʻoiho conductive. No laila, hoʻokiʻekiʻe ʻo PTFE i ka nalowale dielectric ultra-haʻahaʻa a me ka ikaika haʻahaʻa kiʻekiʻe.

Hōʻuluʻulu manaʻo

ʻO ka hoʻopili piha ʻana o nā kaulahao kalapona e nā ʻātoma fluorine, pōkole kiʻekiʻe kiʻekiʻe CF covalent paʻa, a me ka symmetrical non-polar molecular hoʻonohonoho hui pū i nā hana ʻokoʻa o PTFE: non-stickiness, corrosion resistance a kiʻekiʻe uila insulation.

Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Material Technology Co., Ltd.

Inā makemake ʻoe i ka ʻike hohonu e pili ana i nā palena kikoʻī, nā hiʻohiʻona noiʻi a me nā hoʻoponopono i hoʻoponopono ʻia no kā mākou huahana piha, me ka PTFE kiʻekiʻe-mehana lole, PTFE kiʻekiʻe-mehana lipine, PTFE kiʻekiʻe wela mesh kāʻei, seamless fuser kāʻei, hoʻokahi ʻaoʻao PTFE uhi lole, kiʻekiʻe-wela kūʻokoʻa kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe.

Hoʻopili mau mākou i ka ʻoihana lawelawe o ka ʻoihana a me ka kūpaʻa, a hāʻawi me ka naʻau holoʻokoʻa iā ʻoe i nā hoʻonā hoʻokahi a me ka lawelawe noʻonoʻo ma hope o ke kūʻai aku.
