He aha ke kumu hana o ka ʻili non-stick o Teflon?

ʻO Jiangsu Aokai New Materials, kahi mea hana kumu o Teflon kiʻekiʻe-mehana lole, wehewehe i ka ʻepekema ma hope o ia. ʻO ka waiwai maikaʻi ʻole o ka lāʻau ʻo Teflon (inoa kemika: Polytetrafluoroethylene, PTFE) ka mea nui mai ʻelua kumu kumu: haʻahaʻa haʻahaʻa ikehu  a me kona ʻano mole kū hoʻokahi..

1. Haʻahaʻa haʻahaʻa loa o ka ikehu

ʻO kēia ke kumu physicochemical kumu o ka hana lāʻau ʻole. Hoʻoholo ka ikehu o ka ʻili i ka maʻalahi o ka ʻili paʻa e pulu i ka wai.

He haʻahaʻa haʻahaʻa loa ka ikehu ʻili o Teflon (ma kahi o 18.5 mN/m ), ʻoi aku ka haʻahaʻa ma mua o nā mea hoʻopili maʻamau, ʻaila, a i ʻole ka wai (ma kahi o 72 mN/m).

Wahi a ka manaʻo pulu , hiki i ka wai ke hoʻolaha wale ma luna o ka ʻili paʻa inā ʻoi aku ka haʻahaʻa o ka ʻili o ka ʻili ma mua o ka ikehu o ka ʻili. Akā, ʻokoʻa lākou i loko o nā kulu (e like me ka wai ma ka lau lotus) me kahi kihi pili kiʻekiʻe loa (maʻamau ma mua o 90°, a kokoke i 120°).

Ka hopena : ʻO ka wahi pili maoli ma waena o ka mea hoʻopili a me Teflon he liʻiliʻi loa, no laila ʻaʻole hiki ke hoʻokō ʻia kahi hoʻopaʻa mechanical pono a i ʻole ka hoʻopaʻa ʻana. No laila, paheʻe a hiki ke holoi ʻia nā mea haumia.

2. Nā Paʻa C–F ikaika a me ka hoʻokumu ʻana i nā molekala non-polar

He iwi kuamoʻo kalapona i hoʻopuni paʻa ʻia e nā ʻātoma fluorine.

·  ʻO ka ikehu paʻa kiʻekiʻe : ʻO ka paʻa kalapona-fluorine (C–F) kekahi o nā mea paʻa ikaika loa ma ke kemika organik. ʻO kēia ka mea e paʻa loa ai i nā mea kemika ʻo Teflon a aneane ʻole i nā mea āpau (koe naʻe nā metala alkali hoʻoheheʻe a me kekahi mau mea hana fluorinating ikaika). ʻAʻole ia e hana i nā mea paʻa kemika (covalent a i ʻole nā ​​paʻa hydrogen ikaika) me nā mea pili.

·  Polarity haʻahaʻa : ʻOiai he electronegative loa ka fluorine, ʻo kona hoʻonohonoho like ʻana ma ke kaulahao molekala e kāpae i ka manawa dipole holoʻokoʻa. ʻAʻole hiki i ka wai (polar) a me nā aila (ʻaʻole polar akā kiʻekiʻe ka ʻili o ka ʻili) ʻaʻole hiki ke hana i nā mana intermolecular koʻikoʻi (nā ikaika van der Waals nāwaliwali) me Teflon.

3. Hoʻohui like ma waena o ka haʻahaʻa Friction Coefficient a me Non-Stick Performance

ʻOiai ʻo ka helu haʻahaʻa haʻahaʻa e wehewehe nui ana i ka paʻa-paʻa paʻa, hoʻokō ia i ka hana non-stick.

Loaʻa iā Teflon kekahi o nā mea haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ma waena o nā mea paʻa a pau (a puni 0.04).

Ke ho'āʻo nā mea lāʻau paʻa e pili, ʻo ka haʻahaʻa haʻahaʻa loa e pale aku iā lākou mai ka 'paʻa' i ka ʻili. ʻOiai me ka hoʻopaʻa haʻahaʻa ʻana, ka ikaika o waho a i ʻole ka ʻumekaumaha e hoʻoneʻe a wehe maʻalahi ka mea.

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

No nā palena kiko'ī, nā hiʻohiʻona noi a me nā hoʻoponopono kūpono o kā mākou huahana holoʻokoʻa, e like me Teflon lole wela kiʻekiʻe, Teflon high-temperature tape, Teflon high-temperature mesh belts, seamless belts for bonding machines, one-sided PTFE cloth, high-temperature resistant conveyor belts, high-temperature mesh belts.

Ke kākoʻo nei mākou i kahi loiloi lawelawe ʻoihana a me ka ʻoiaʻiʻo, a ua hoʻolaʻa ʻia i ka hāʻawi ʻana iā ʻoe i nā hopena hoʻokahi a me ka lawelawe hoʻolohe!
