He aha kēia mea ?
ʻO ka carbon tetrafluoride he kinoea kala ʻole a ʻala ʻole i ka mahana maʻamau a me ke kaomi. ʻAʻole inert kemika ma muli o nā paʻa kalapona-fluorine ikaika. ʻO kēia ka mea i hana ʻole ai me nā mea maʻamau ma lalo o nā kūlana maʻamau. ʻO CF4 kahi kinoea hoʻomehana honua ikaika, e kōkua ana i ka hoʻomehana honua.
Ma hea e hoʻohana ai i kēia mea?
1. Semiconductor Manufacturing: Hoʻohana nui ʻia ʻo CF4 i ka ʻoihana uila no ka etching plasma a me nā kaʻina hoʻoheheʻe kemika (CVD). Kōkua ia i ka etching pololei o nā wafer silika a me nā mea ʻē aʻe i hoʻohana ʻia i nā mea semiconductor. He mea koʻikoʻi kona inertness kemika i ka pale ʻana i nā hopena makemake ʻole i kēia mau kaʻina hana.
2. Dielectric Gas: Hoʻohana ʻia ʻo CF4 ma ke ʻano he kinoea dielectric i nā mea uila uila kiʻekiʻe a me nā mea hoʻololi kinoea kinoea (GIS). ʻO kona ikaika dielectric kiʻekiʻe a me nā waiwai insulating uila maikaʻi loa e kūpono ia no ka hoʻohana ʻana i kēia mau noi.
3. Pahu: Ua hoʻohana ʻia ʻo CF4 ma ke ʻano he refrigerant i kekahi mau noi haʻahaʻa haʻahaʻa, ʻoiai ua hoʻemi ʻia kona hoʻohana ʻana ma muli o nā hopohopo kaiapuni ma luna o kona hiki ke hoʻomehana honua.
4. Tracer Gas: Hiki ke hoʻohana ʻia ma ke ʻano he tracer gas i nā kaʻina ʻike leak, ʻoi aku ka nui no ka ʻike ʻana i nā leaks i nā ʻōnaehana kiʻekiʻe-vacuum a me nā mea hana ʻoihana.
5. Calibration Gas: CF4 ua hoʻohana 'ia e like me ka calibration kinoea ma kinoea analyzers a me ke kinoea detectors ma muli o kona ike a paʻa waiwai.
6. Noiʻi a Hoʻomohala: Hoʻohana ʻia ia i loko o ka noiʻi a me ka hoʻomohala ʻana no nā kumu like ʻole, me ka ʻepekema waiwai, kemika, a me nā hoʻokolohua physics.
E hoʻomaopopo he ʻokoʻa paha nā noi a me nā lula no ka hoʻohana ʻana i kēia mea/huahana ma muli o ka ʻāina, ka ʻoihana a me ke kumu. E hahai mau i nā alakaʻi palekana a e nīnau i kahi loea ma mua o ka hoʻohana ʻana i kēia mea / huahana i kekahi noi.
