Nitrogen (N2)

Nā palena ʻenehana

ʻO Nitrogen (N2) ka hapa nui o ka lewa o ka honua, ʻo ia ka 78.08% o ka huina. He kala ʻole, ʻala ʻole, ʻono ʻole, ʻona ʻole a kokoke loa i ke kinoea inert. ʻAʻole hiki ke puhi ʻia ka Nitrogen a ua manaʻo ʻia ʻo ia he kinoea hoʻohuhū (ʻo ia hoʻi, ʻo ka hanu ʻana i ka nitrogen maʻemaʻe e hoʻonele i ke kino o ke kanaka i ka oxygen). ʻAʻole hana kemika ʻo Nitrogen. Hiki iā ia ke hana me ka hydrogen e hana i ka ammonia ma lalo o ke kiʻekiʻe wela, ke kaomi kiʻekiʻe a me nā kūlana catalyst; hiki ke hui pū me ka oxygen e hana i ka nitric oxide ma lalo o nā kūlana hoʻokuʻu. Ua kapa ʻia ʻo Nitrogen he kinoea inert. Hoʻohana ʻia ia i loko o kekahi mau lewa inert no ka hoʻomaʻamaʻa metala a i loko o nā puʻupuʻu e pale ai i ka arcing, akā ʻaʻole inert kemika. He mea koʻikoʻi ia i ke ola o nā mea kanu a me nā holoholona, ​​a he ʻāpana o nā pūhui pono he nui. Hoʻohui ʻia ka Nitrogen me nā metala he nui e hana i nā nitrides paʻakikī, hiki ke hoʻohana ʻia e like me nā metala paʻa ʻole. ʻO ka liʻiliʻi o ka nitrogen i loko o ke kila e kāohi i ka ulu ʻana o ka palaoa i nā wela kiʻekiʻe a e hoʻonui pū i ka ikaika o kekahi mau kila. Hiki ke hoʻohana ʻia e hana i nā ʻili paʻakikī ma ke kila. Hiki ke hoʻohana ʻia ka Nitrogen e hana i ka ammonia, nitric acid, nitrate, cyanide, etc.; i ka hana ʻana i nā mea pahū; ka hoʻopiha ʻana i nā thermometer kiʻekiʻe, nā ʻōpuʻu incandescent; ka hana ʻana i nā mea inert e mālama i nā mea, hoʻohana ʻia i nā pahu maloʻo a i ʻole nā ​​ʻeke mīkina lima. ʻO ka nitrogen wai i ka wā e maloʻo ai ka meaʻai; hoʻohana ʻia ma ke ʻano he mea hoʻomaʻamaʻa ma ka hale hana. Pono e mālama pololei ʻia ka Nitrogen i kahi ea maikaʻi, palekana a me ka ʻole o ka ea, a ʻaʻole pono 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:

①Ma nā ʻano mea hoʻohana analytical like ʻole:

ʻO ke kinoea halihali no ka chromatography kinoea, ke kinoea kākoʻo no nā Electron Capture Detectors, Liquid Chromatography Mass Spectrometry, hoʻomaʻemaʻe kinoea no Inductive Couple Plasma.

②Material:

1. E hoʻopiha i nā ʻōpuʻu kukui.
2. I loko o ka ea antibacterial a me nā mea kani no nā noi olaola.
3. Ma keʻano he mea i loko o Controlled Atmosphere Packaging a me Modified Atmosphere Packaging applications, 4. Calibration gas mixtures no nā ʻōnaehana nānā kaiapuni, laser gas mixtures.
5. No ka hoʻomaloʻo ʻana i nā hopena kemika he nui e hoʻomaloʻo i nā huahana like ʻole.

③Liquid nitrogen:

E like me ka hau maloʻo, ʻo ka hoʻohana nui ʻana o ka nitrogen wai ma ke ʻano he refrigerant.

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;
