Hūhā (H2)

Nā palena ʻenehana

Loaʻa i ka Hydrogen kahi ʻano kemika o H2 a me ke kaumaha molekala o 2.01588.Ma lalo o ka wela a me ke kaomi maʻamau, he kinoea wela loa, ʻaʻole waihoʻoluʻu, ʻākala, ʻono a ʻono ʻole i paʻakikī ke hoʻoheheʻe ʻia i loko o ka wai, a ʻaʻole e hoʻopili me ka hapa nui o nā mea.Eia nō naʻe, ma lalo o ke kaomi kiʻekiʻe a me nā kūlana wela haʻahaʻa, hana ka hydrogen me nā mea hydrocarbon he nui i loko o kahi hopena catalytic.ʻO ka hydrogen ke kinoea mānoanoa liʻiliʻi loa i ʻike ʻia ma ka honua.ʻO ka mānoanoa o ka hydrogen he 1/14 wale nō ia o ka ea, ʻo ia hoʻi, ma ka lewa maʻamau 1 a me 0°C, ʻo 0.089g/L ka nui o ka hydrogen.ʻO ka hydrogen ka mea nui o ka ʻoihana.Pono nā ʻoihana ʻaila a me nā kemika i ka nui o ka hydrogen.Ma waena o lākou, ʻo ka hana ʻana i nā wahie mōʻalihaku a me ka hana ʻana o ka amonia e ka kaʻina Hubble ʻo ia nā noi nui.Ma waho aʻe o ka hoʻohana ʻana i nā hopena kemika, loaʻa i ka hydrogen ka nui o nā noi i ka physics a me ka ʻenekinia.Hiki ke hoʻohana ʻia e like me ke kinoea pale i kekahi mau ʻano kuʻi.ʻO ka hydrogen kekahi mea koʻikoʻi ʻoihana kinoea a me ke kinoea kūikawā, a he nui kona mau noi i ka ʻoihana uila, ʻoihana metallurgical, ka hoʻoili ʻana i ka meaʻai, ke aniani lana, ka synthesis organik maikaʻi, aerospace, etc. I ka manawa like, hydrogen kekahi ikehu lua maikai (e pili ana ka ikehu lua i ka ikehu e pono ke hanaia mai ka ikehu mua e like me ka ikehu o ka la, lanahu, a pela aku) a me ka wahie kinoea.ʻAʻā ia e like me ka lapalapa alohilohi, kahi paʻakikī ke ʻike.ʻO ka wai wale nō nā huahana o ke ahi.Hiki ke hoʻohana ʻia ka hydrogen ma ke ʻano he mea maka no ka ammonia synthetic, synthetic methanol, a me synthetic hydrochloric acid, ma ke ʻano he mea hoʻohaʻahaʻa no ka metallurgy, a ma ke ʻano he hydrodesulfurization agent i ka hoʻomaʻemaʻe ʻaila.No ka mea he kinoea kinoea hiki ke puhi ʻia ka hydrogen, pono e mālama ʻia i loko o kahi hale kūʻai anuanu.ʻAʻole pono ka mahana o ka hale kūʻai ma mua o 30 ° C.E mālama i ke ahi a me nā kumu wela.E pale pololei i ka lā.Pono e mālama ʻokoʻa mai ka oxygen, ka ea i hoʻopaʻa ʻia, nā halogens (fluorine, chlorine, bromine), oxidants, a me nā mea ʻē aʻe.ʻO ka kukui, ka ea a me nā mea hana ʻē aʻe i loko o ka lumi mālama e pono e hōʻoia i ka pahū, me nā hoʻololi i waho o ka hale kūʻai, a hoʻolako ʻia me nā ʻano like a me ka nui o nā lako ahi.E pāpā i ka hoʻohana ʻana i nā mea hana mīkini a me nā mea hana e pili ana i ka ʻā

Noi:

①Hoʻohana ʻoihana:

Ma ke kaʻina hana aniani kiʻekiʻe a me ka hana ʻana i nā microchips uila.

②Hoʻohana Lapaʻau:

Hāʻawi ʻia no ka mālama ʻana i nā ʻano maʻi, e like me ka puʻupuʻu, ka hahau ʻana.

③Ma ka hana semiconductor:

ʻO ke kinoea halihali, ʻoi aku ka nui no ka chromatography kinoea hoʻoheheʻe silika.

Pūʻolo maʻamau:

Pōmaikaʻi:

①Ma mua o ʻumi makahiki ma ka mākeke;

②Ka mea hana palapala ISO;

③Hoʻouna wikiwiki;

④Stable kumu kumu waiwai;

⑤ ʻO ka ʻōnaehana hoʻopaʻa inoa pūnaewele no ka hoʻokele maikaʻi ʻana i kēlā me kēia pae;

⑥Ke koi kiʻekiʻe a me ke kaʻina hana no ka mālama ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;
