Helium (He)

Nā ʻāpana ʻenehana

He kinoea kakaikahi ka Helium, he kinoea māmā loa, kala ʻole a me ka ʻala ʻole. ʻAʻohe hana kemika, a he paʻakikī ke hana me nā mea ʻē aʻe ma lalo o nā kūlana maʻamau. Loaʻa iā ia nā waiwai kemika paʻa a he melemele ʻeleʻele ke hana i ka hoʻokuʻu haʻahaʻa haʻahaʻa. Hiki ke hoʻohana ʻia ka Helium ma ke ʻano he mea kaomi a me ka supercharger no ka wahie wai rocket, a hoʻohana ʻia i ka nui o nā missiles, spacecraft a me nā mokulele supersonic; e like me ke kinoea pale i ka wā o ka hoohehee a me ka wiliwili, hoʻohana 'ia i ka hana moku, mokulele, spacecraft, rockets, a He mea nui loa ka hana ana i na mea kaua; ʻO ka helium he maikaʻi loa ka permeability a hoʻohana ʻia e hoʻomaʻalili i nā reactors nuklea, a e ʻike i nā leaka i loko o nā pōhaku a me nā paipu nuklea reactors a me nā mea uila a me nā uila; ʻO ka helium he haʻahaʻa haʻahaʻa haʻahaʻa a me ke kaumaha kaumaha, a ʻaʻole hiki ke hoʻopau ʻia a hiki ke hoʻohana ʻia e hoʻopiha i nā ʻōpuʻu kukui a me nā paipu neon. He kinoea maikaʻi hoʻi ia no nā baluna a me nā mokulele; hiki ke loaʻa ka helium wai i kahi mahana haʻahaʻa kokoke i ka wela piha (-273 ° C) a hoʻohana ʻia e hana i nā lako superconducting; ʻO ka helium he ʻano kinoea inert, ʻoi aku ka haʻahaʻa o ka solubility i loko o ke koko ma mua o ka nitrogen, no laila ʻoi aku ka haʻahaʻa o kona anesthesia ma mua o ka nitrogen. No laila, hui pinepine ʻia ka helium a me ka oxygen e like me ke kinoea hanu no nā mea luʻu. Pono e mālama pono ʻia ka Helium ma kahi puka makani maikaʻi, palekana a me ka ʻole o ka ea, a ʻaʻole ʻoi aku ke kiʻekiʻe o ka mahana mālama ma mua o 52°C. ʻAʻole pono e loaʻa nā mea wela i loko o kahi waiho ʻana a mālama ʻia mai nā wahi komo pinepine a puka i waho a me nā puka ulia pōpilikia, ʻaʻohe paʻakai a me nā mea ʻino ʻē aʻe. No nā pahu hau i hoʻohana ʻole ʻia, pono e hoʻopaʻa maikaʻi ʻia ka pāpale valve a me ka pahu puka puka, a mālama ʻia nā cylinders ʻole mai nā pahu piha. E hōʻalo i ka mālama nui a me ka manawa mālama lōʻihi, a mālama i nā moʻolelo mālama maikaʻi.

Noi:

1. Hoʻohana ʻia ka hoʻoheheʻe cryogenic:

Hoʻohana nui ʻia ke kinoea helium ma ka kaʻaahi maglev a me nā mea hana kiʻi Nuclear magnetic resonance (NMR).

2. Hoʻohana Baluna:

Inflat no ka pōlele no ka pāʻina lā hānau a i ʻole ka hoʻolauleʻa ʻana no ka mokulele.

3. Nānā Nānā:

Hoʻohana nui ʻia ke kinoea helium i ka ʻike leak vaccum e like me ka helium mass spectrometer leak detector.

4.Shielding Gas:

Hoʻohana pinepine ʻia ka Helium e like me ka magnesium, zirconium a me ka aluminika, titanium a me nā metala ʻē aʻe e hoʻopaʻa ʻia ai ke kinoea pale.

Nui pūʻolo:

Pono:

1. Hoʻopuka kā mākou hale hana i ka Helium mai ke kiʻekiʻe kiʻekiʻe o nā mea maka, ʻokoʻa ke kumu kūʻai.
2. Hoʻokumuʻia ka Helium ma hope o nā manawa he nui o ka hoʻomaʻemaʻe a me ka hoʻoponoponoʻana i kā mākou hale hana.
3. I ka wā o ka hoʻopiha ʻana, pono e hoʻomaloʻo mua ʻia ka cylinder no ka manawa lōʻihi (ma ka liʻiliʻi o 16hrs), a laila hoʻomaʻemaʻe mākou i ka cylinder, hope mākou e hoʻoneʻe iā ia me ke kinoea kumu.
4. Ua noho mākou ma ke kahua Gas no nā makahiki he nui, ʻike waiwai i ka hana ʻana a me ka lawe ʻana aku e lanakila mākou i nā mea kūʻai aku' hilinaʻi, ʻoluʻolu lākou i kā mākou lawelawe a hāʻawi iā mākou i ka ʻōlelo maikaʻi.
