ʻO ka mea mua, ke ʻano o ka nitrogen

ʻO ka Nitrogen, ma lalo o nā kūlana maʻamau, he kinoea kala ʻole, ʻono ʻole, ʻaʻala ʻole a ʻaʻohe mea ʻawaʻawa.He 78.12% ka nui o ka lewa a pau o ka lewa.I ka mahana maʻamau, he kinoea.Ma ke kaomi lewa maʻamau, lilo ia i wai waihoʻoluʻu ke hoʻomaha ʻia i -195.8 ℃.Ke hoʻolili ʻia a hiki i -209.86 ℃, lilo ka hau hau i ka hau.Hoʻohana: chemical synthesis (synthetic nylon, acrylic fiber, synthetic resin, synthetic rubber a me nā mea waiwai ʻē aʻe), nā kaʻa kaʻa (hiki i ka nitrogen ke hōʻemi pono i ka walaʻau o nā kaʻa, hoʻolōʻihi i ke ola lawelawe o nā kaila).No ka mea, ʻaʻole inert kemika, hoʻohana pinepine ʻia ia ma ke ʻano he kinoea pale, e like me ka melon, hua, meaʻai, a me ke kinoea hoʻopiha kukui.

ʻElua, ka hoʻohana ʻana i ka nitrogen

ʻO ka Nitrogen i ka metallurgy, ka ʻoihana kemika, ka ʻoihana māmā, ka uila a me nā keʻena ʻē aʻe, e like me ke kinoea feedstock, ke kinoea pale, ke kinoea pani a me ke kinoea sealing.Hoʻohana nui ʻia nā huahana nitrogen wai i ka mālama ʻana i nā meaʻai maloʻo, nā mea kanu a me nā huaʻai.Hoʻohana nui ʻia ia i ka mahiʻai a me ka mahiʻai holoholona, ​​​​e like me ka mālama ʻana i ka palaoa insecticidal, ka mālama ʻana i ka semen o nā holoholona ʻoi aku ka maikaʻi, etc. ʻO ia ka constituent o nā protein i nā mea kanu a me nā holoholona.

Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻomohala ʻana i ka hoʻokele waiwai, ke hoʻonui nei ka pae noi o ka nitrogen i kēlā me kēia lā.

E hoʻohana i ka inertia o ka nitrogen

ʻO ka hoʻomaʻamaʻa ʻana i ka metala: ka hoʻopau ʻana i ka ʻālohilohi, ka annealing mālamalama, ka carburizing, carbonitriding, nitriding palupalu a me nā mea ʻē aʻe e pili ana i ka hau e hoʻomaʻamaʻa ʻia i ka wela o ke kumu nitrogen, ka hoʻoheheʻe ʻana a me ka pauka metallurgy puhi kaʻina hana pale kinoea, etc.

ʻOihana Metallurgical: hoʻolei mau ʻia, ʻōwili mau ʻia, ke kila annealing pale ea, BOF kiʻekiʻe pūhui e puhi ana i ka nitrogen steelmaking, steelmaking BOF seal, BF top seal, BF ironmaking pulverized coal injection a me nā hana ʻē aʻe.

Ke hoʻohana nei i ka nitrogen wai cryogenic

'Oihana uila: kaapuni hoʻohui nui, ka pahu kiʻi kiʻi TV kala, nā ʻāpana TV a me nā mea hoʻopaʻa leo a me ka pale ʻana i ke kaʻina hana conductor, etc.

ʻO ka mālama ʻana i ka meaʻai: ka meaʻai, ka huaʻai (hua), nā mea kanu a me nā mea mālama ea a me ka mālama ʻana, ka ʻiʻo, ka paʻakai, ka sinapi, ke kī a me ka kofe, e like me ka ʻeke hou, jam, e like me ka mālama ʻana i ka oxygenation nitrogen, nā ʻōmole like ʻole o ka hoʻomaʻemaʻe waina a me ka uhi ʻana, etc.

ʻOihana lāʻau lapaʻau: ʻO ka lāʻau lapaʻau Kina (ginseng) ka hoʻopiha piha ʻana i ka mālama ʻana a me ka mālama ʻana, ka hoʻopiha ʻana i ka lāʻau lapaʻau komohana i ka nitrogen hoʻopiha, ka pahu mālama a me ka pahu nitrogen e hoʻopiha ana i ka oxygen, ka lawe ʻana i ka lāʻau pneumatic o ke kumu ea, etc.

ʻOihana kemika: hoʻololi, hoʻomaʻemaʻe, hoʻopaʻa ʻana, ʻike leak a me ka pale ʻana i ke kinoea, hoʻomaloʻo maloʻo, catalyst regeneration, petroleum fractionation, chemical fiber production, etc.

ʻOihana Fertilizer: mea maka o ka mea hoʻomomona nitrogen.Kope palekana Catalyst, holoi kinoea, etc.

ʻOihana Pākīpika: ka hoʻoili pneumatic o nā ʻāpana plastik, ka hana ʻana i ka plastic a me ka pale ʻana i ka oxidation.

ʻO ka ʻoihana Rubber: ka pahu pahu a me ka mālama ʻana, ka hana ʻana o nā kaila, etc.

ʻOihana aniani: Ke kinoea pale no ke kaʻina hana aniani lana.

ʻO ka ʻoihana Petroleum: ka hoʻopiha piha ʻana a me ka hoʻomaʻemaʻe ʻana i ka mālama ʻana, nā ipu, nā hale kiaʻi catalytic a me nā pipeline, ka ʻike ʻana i ka leak o nā ʻōnaehana hoʻokele, etc.

Ka hoʻomohala ʻana i ka aila waho: uhi kinoea o nā kahua ʻaila o waho, ʻo ka nitrogen injection no ka hoʻihoʻi ʻana i ka aila, pahu a me ka pahu inerting, etc.

ʻO ka waiho ʻana o ka puʻupuʻu: e pale aku i ka cellar, ka hale kūʻai a me nā hale kūʻai ʻē aʻe i hoʻopau ʻia i ka lepo a me ka pahū, etc.

Hoʻouna: ʻaila tanker hoʻomaʻemaʻe kinoea, etc.

ʻenehana Aerospace: hoʻoulu wahie rocket, hoʻokuʻu i ke kinoea pani pani a me ke kinoea palekana palekana, ke kinoea hoʻokele astronaut, ke keʻena simulation space, ke kinoea hoʻomaʻemaʻe pipeline mokulele, etc.

ʻO nā mea ʻē aʻe: pena a me ka uhi ʻana i ka oxygenation nitrogen e pale ai i ka polymerization o ka maloʻo ʻana o ka aila, ka aila a me nā pahu mālama kinoea kūlohelohe a me nā ipu nitrogen oxygenation, etc.

Ke hoʻohana nei i ka nitrogen wai cryogenic

ʻO ka lāʻau lapaʻau Hypothermia: ʻokiʻoki i ka hypothermia, cryotherapy, hoʻoheheʻe koko, hoʻoheheʻe lāʻau a me cryopatter, etc.

Biomedicine: cryopreservation a me ka lawe ʻana i nā mea kanu makamae, nā mea kanu kanu, genetic germplasm, etc.
