Nā Aila Perfluoropolyether (PFPE) no nā Pump Pumi
ʻO nā aila Perfluoropolyether PFPE ka thermally stable, chemically inert, a kūpono me nā metala, hydrogenated polymers, oxygen a me nā kinoea hoʻopaʻapaʻa a hiki i nā wela kiʻekiʻe loa.
Hoʻolālā kūikawā ʻia nā aila PFPE no nā ʻano pahu pahu pahu kikoʻī kahi e hāʻawi ai kā lākou mau waiwai kūʻokoʻa i nā pono nui.
Inā pilikia ʻoe i ke koho ʻana i ka aila ʻaila pauma kūpono no kāu pono, ua hele mai ʻoe i kahi kūpono. I kēia lā, ke nānā nei mākou i ka perfluoropolyether (PFPE) ʻaila ʻaila hoʻomaʻemaʻe - ka wehewehe ʻana i ke ʻano o ka pauma e hana maikaʻi ai lākou a pehea ka ʻokoʻa o lākou mai nā ʻaila ʻaila ʻē aʻe.
1. He aha ke ʻano o nā ʻōpala ʻauʻau e hana maikaʻi me nā ʻaila PFPE?
ʻO nā Pumps Vacuum Rotary Vane
Nā Pump Diffusion
Na Pump Turbomolecular
2.Key 'ano o ka PFPE Vacuum aila
Pehea ka ʻokoʻa o nā ʻaila PFPE me nā ʻaila ʻaila ʻē aʻeHoʻohālikelike ʻia me nā ʻaila mineral a me nā aila hydrocarbon synthetic

Nā noi kahi e pono ai nā aila PFPE
√ ʻO ka hana semiconductor: kahi mea koʻikoʻi ka hoʻomaʻemaʻe kiʻekiʻe a me ka hoʻomaʻemaʻe kemika.
√ Noiʻi ʻana i ka hale hana: No nā lako ʻepekema koʻikoʻi e koi ana i ka hoʻohaumia liʻiliʻi.
√ Nā keʻena simulation Space: Ma kahi o nā kūlana koʻikoʻi a me ka hilinaʻi nui.
√ Ka hoʻoponopono kemika: Ma nā kaiapuni me nā kemika a me nā kinoea.
√ Hana ʻana i ka lāʻau lapaʻau: Ma kahi e pono ai ka maʻemaʻe huahana.
√ Nā noi nuklea: Ma muli o nā waiwai pale radiation.
√ lawelawe oxygen: Ma kahi o nā aila maʻamau e pilikia ai ka palekana.
