He aha ka PTFE?

E hoʻomaka kākou i kā mākou ʻimi ʻana iā Teflon vs PTFE me ka nānā pono ʻana i ke ʻano o ka PTFE. No ka hāʻawi ʻana i kona inoa piha, polytetrafluoroethylene he polymer synthetic i loaʻa i ʻelua mau mea maʻalahi; kalapona a me ka fluorine. Loaʻa ia mai ka tetrafluoroethylene (TFE) a loaʻa iā ia kekahi mau waiwai kūʻokoʻa e lilo ia i mea pono i nā ʻano o nā noi. ʻo kahi laʻana:

• Kiʻekiʻe loa ka helu heheʻe: Me kahi helu heheʻe ma kahi o 327°C, he liʻiliʻi loa nā kūlana kahi e pōʻino ai ka PTFE e ka wela.
• Hydrophobic: 'O ke kū'ē i ka wai 'o ia ho'i, 'a'ole loa ia e pulu, pono ia i ka kuke 'ana, ka lole 'eha a me nā mea hou aku.
• Kemika inert: ʻAʻole e hōʻino ka hapa nui o nā solvents a me nā kinikona i ka PTFE.
• Ka helu haʻahaʻa o ka friction: ʻO ka coefficient o friction o PTFE kekahi o ka haʻahaʻa loa o kekahi paʻa i ke ola, ʻo ia hoʻi, ʻaʻohe mea e pili i ia.
• Ka ikaika flexural kiʻekiʻe: ʻO kona hiki ke kulou a hoʻopololei, ʻoiai ma nā haʻahaʻa haʻahaʻa, ʻo ia ka mea hiki ke hoʻohana maʻalahi i nā ʻano like ʻole me ka nalowale ʻole o kona kūpaʻa.

He aha ka Teflon?

Ua ʻike ʻia ʻo Teflon ma kahi pōʻino, e kekahi kanaka ʻepekema i kapa ʻia ʻo Kauka Roy Plunkett. E hana ana ʻo ia no DuPont ma New Jersey e hoʻāʻo ana e hoʻomohala i kahi pahu hau hou, i kona ʻike ʻana ua kahe ke kinoea TFE mai loko mai o ka ʻōmole āna e hoʻohana nei, akā ʻaʻole i kaumaha ka ʻōmole. No ka ʻike i ke kumu o ke kaumaha, ua ʻimi ʻo ia i loko o ka ʻōmole a ʻike ʻia ua uhi ʻia me kahi mea waxy, paheʻe a ikaika loa, a mākou i ʻike ai ʻo Teflon.

ʻO wai ka maikaʻi ma Teflon vs PTFE?

Inā ʻoe e noʻonoʻo nei i kēia manawa, ua ʻike mua ʻoe i kā mākou e ʻōlelo ai ma aneʻi. ʻAʻohe mea lanakila, ʻaʻohe huahana ʻoi aku ka maikaʻi a ʻaʻohe kumu e hoʻohālikelike ai i nā mea ʻelua. I ka hopena, inā ʻoe e noʻonoʻo nei e pili ana iā Teflon vs PTFE, mai kahaha hou aku, no ka mea, ʻoiaʻiʻo, hoʻokahi mea like, ʻokoʻa wale nō ma ka inoa a ʻaʻohe mea ʻē aʻe.
