Liquid Nitrogen: Nā Pono a me ka hoʻohana ʻana i nā ʻoihana like ʻole

2023-12-14

Naikokene waihe wai waihoʻoluʻu, ʻala ʻole, a ʻaʻole hiki ke puhi ʻia i hoʻohana mau ʻia i nā ʻano hana ʻenehana. Hana ʻia ia ma ka hoʻoheheʻe ʻana i ka naikokene lewa, ʻo ia ke kinoea nui loa i ka lewa o ka Honua. He wahi paila ka wai o ka nitrogen -195.8 degere Celsius, a i ʻole -320.4 degere Fahrenheit. ʻO kēia ka mea i loaʻa i ka mea anuanu loa.

wai nitrate

Nā waiwai o ka Nitrogen Liquid:

1. Haʻahaʻa Mahana:

ʻO kekahi o nā mea kaulana loa o ka nitrogen wai kona wela haʻahaʻa loa. Ma ka -195.8 degere Celsius, hiki iā ia ke hoʻokuʻu koke i nā mea ma ka pili ʻana. He mea kūpono kēia waiwai no nā noi cryogenic, e like me ka mālama ʻana i nā laʻana olaola, nā huahana meaʻai manuahi, a me ka hana ʻana i nā superconductors.

2. Inertness:

ʻAʻole kemika wai ka wai, ʻo ia hoʻi, ʻaʻole ia e hana me ka nui o nā mea. He mea kūpono kēia waiwai no ka mālama ʻana a me ka lawe ʻana i nā mea pahū, no ka mea e hōʻemi ana i ka hopena o ka puhi ʻana a pahū paha. Hoʻohui ʻia, hiki i kona ʻano inert ke hoʻohana ʻia i nā kaʻina hana like ʻole a ma ke ʻano he mea hoʻomaha no nā ʻāpana uila.

3. Hoʻonui ma luna o ka evaporation:

Ke hōʻike ʻia i ka wela lumi, e hoʻomāhuahua a hoʻonui ʻia ka nitrogen wai ma kahi o 700 mau manawa. Hiki i kēia hoʻonui ke hana i ka ikaika ikaika, e hoʻohana i ka nitrogen wai no nā noi e like me ka rocket propulsion a ma ke ʻano he mea hoʻomaha i nā kaʻina hana.

 

Hoʻohana i ka Nitrogen Liquid i nā ʻoihana like ʻole:

1. ʻOihana Meaʻai:

Ua hoʻololi hou ʻia ka ʻoihana meaʻai ma ka ʻae ʻana i ka hana ʻana o nā mea kanu kūʻokoʻa. Hoʻohana maʻamau ia e hoʻokuʻu koke i nā huahana meaʻai, mālama i ko lākou ʻano hou a me ke ʻano. Hoʻohana pinepine ʻia kēia ʻano hana i ka hana ʻana i nā ice cream, nā mea ʻai maloʻo maloʻo, a me nā meaʻai maloʻo maloʻo. Hoʻohui ʻia, hoʻohana ʻia ka nitrogen wai no ka mālama ʻana i ka meaʻai a me ka lawe ʻana e hōʻemi i ka spoilage a mālama i ka maikaʻi o ka huahana.

2. ʻOihana Lapaʻau a Lapaʻau:

I loko o ka lāʻau lapaʻau, ʻike nui ʻia ka nitrogen wai i nā kaʻina cryotherapy, kahi i hoʻohana ʻia e hoʻokuʻu a luku i nā ʻiʻo kūlohelohe, e like me nā warts a i ʻole nā ​​​​pūnaewele precancerous. Hoʻohana ʻia no ka cryopreservation o nā laʻana olaola, me ka sperm, nā hua, a me nā embryos no ka mālama ʻana i ka momona. Eia kekahi, hoʻohana nā hui lāʻau lapaʻau i ka nitrogen wai i ka wā o ka hana ʻana i ka lāʻau lapaʻau e mālama i nā haʻahaʻa haʻahaʻa e pono ai no kekahi mau hopena a mālama i nā mea koʻikoʻi.

3. Hana a me ka ʻenekinia:

He mea koʻikoʻi ka wai nitrogen i ka hana ʻana a me nā ʻoihana ʻenehana ma muli o kāna mau mea hoʻomaha. Hoʻohana ʻia ia ma ke ʻano he mea hoʻoluʻu i nā kaʻina hana machining, e like me ka wili, ʻokiʻoki, a me ka ʻeli ʻana, e pale i ka wela a hoʻonui i ke ola mea hana. Hoʻohui ʻia, hoʻohana ʻia ka nitrogen wai i nā kaʻina mālama wela metala e hoʻomaikaʻi i nā waiwai waiwai e like me ka paʻakikī a me ka lōʻihi. ʻO kona haʻahaʻa haʻahaʻa hoʻi e hoʻomaʻamaʻa i ka hōʻemi ʻana i nā ʻāpana a kōkua i ka hana ʻana i nā ʻāpana pololei.

4. Noiʻi a hoʻomohala:

I loko o nā keʻena noiʻi, hoʻohana ka nitrogen wai i nā kumu he nui. Hoʻohana ʻia ia ma ke ʻano he mea hoʻomaʻamaʻa no nā superconducting magnets i ka nuklear magnetic resonance (NMR) spectroscopy a me nā mīkini hoʻohālikelike magnetic (MRI). Eia kekahi, hiki iā ia ke aʻo i nā hanana haʻahaʻa haʻahaʻa i nā hoʻokolohua physics a me kemika. ʻO kona wahi hoʻolapalapa haʻahaʻa hoʻi e lilo ia i mea hoʻomaha maikaʻi no nā cryostats i hoʻohana ʻia i nā noi ʻepekema like ʻole.

5. ʻOihana Kaʻa:

Loaʻa ka wai nitrogen i nā noi i ka ʻoihana kaʻa, ʻoi loa i ka hana ʻana i nā kaila. Hoʻohana ʻia ia e hoʻokuʻu koke i nā pūhui lāʻau i ka wā o ka hana vulcanization, kahi e hoʻomaikaʻi ai i ka paʻa a me ka hana ʻana o ke kaʻa. Hoʻohana pū ʻia ka nitrogen wai i nā keʻena hoʻāʻo ʻenekini e hoʻohālikelike i nā kūlana anuanu loa a nānā i ka hana ʻenekini ma lalo o ia mau kūlana.


ʻO nā waiwai kūʻokoʻa o Liquid nitrogen ka mea i waiwai nui ma nā ʻoihana like ʻole. ʻO kona haʻahaʻa haʻahaʻa, inertness, a me ka hoʻonui ʻana i ka evaporation e hiki ai i nā ʻano hana like ʻole, mai ka hana ʻana i ka meaʻai a hiki i nā kaʻina olakino a me ka noiʻi ʻepekema. Ke holomua nei ka ʻenehana, e hoʻonui hou ʻia ka hoʻohana ʻana i ka wai nitrogen, e hāʻawi ana i ka hana hou a me ka holomua ma nā ʻano he nui.
