Wai naikokene

Wai naikokene mea inert, colorless a me ka odorless kinoea. He mea 'ole-corrosive, ole-flammable. He kinoea kūpono ai ka nui loa o ka lewa (78.03% o ka huina). ʻOiai wai naikokene a e ole kākoʻo'ā, naʻe ia mea inert, koe wale no ka poe hihia ma kahi e mea wela i ka kiʻekiʻe loa mahana, a ua pili i kekahi o ka K'lauea ke hooheheeia e like me likiuma, makanekiuma. Nolaila, i ka hui nitrides i hana. Ua hiki no hoi pane koke me ka o oxygen, kūpono ma ka ho okumu o ka naikokene oxides a me ka naikokene hui me hydrogen ma ke alo o catalysts - ammonia.

Makaukau o ka wai a naikokene ma ka hanalima ana
Naikokene wai a me ke kinoea hoomakaukau i ke ala hookahi - mai ka Ambient ea. Ma keʻena hoʻokolohua ka mea, ua loaa i ka decomposition naoh o'amoniuma nitrite. Kēia naoh He exothermic. A no ke aha la e hele me ke kala o ka 80 kcal (335 kJ) o ka ikehu. Ua pono anuanu moku ana paio hahana maoli nō ua koi 'ia e hoʻomaka i ka naoh e paka wai naikokene. Nō hoʻi, hakakino naikokene ma ka hana i loaa mai ma ka fractional distillation o ka wai a ea lewa. Ua hiki ke loaa ma keia hana e like me "ka lewa naikokene." All epekema ma a e imi wai a naikokene kuhikuhi ma ka palekana a me ka maʻemaʻe huahana no ka hanalima, 'inikua a me ko ka hale ona me nā huahana
Hopena ma luna o kanaka ola
ʻOiai wai naikokene mea inert a me ka mea oleʻawahia, ka mea hiki ke hoʻonāukiuki he kanaka suffocation, e like me ka mea hiki ke pau ka i ka oxygen ma loko o ka lewa ma lalo o ka 'ilikai pono e hānai iā ola. Inhalation o ka naikokene ma excessive dala hiki i pōniuniu, nausea, ka luaʻi, poho o ka ike paka i a me ka make. Make paha ia i ka hopena o ka poho o ke kohoʻia a me ka ike paka i, i hiki ole ai pakiko-hoʻopakele mai ua hoʻohaumiaʻia wahi. At haʻahaʻa o oxygen lehulehu, poho o ka ike paka i a me ka make e hana ana i loko o kekahi mea o nā kekona. Nā limahana, a me hoʻopakele poe hana, e ole e komo i ka pā me ka pakiko-i kakauiaʻi maluna hanu i hoʻomākaukauʻia ai respirator, ina o ka oxygen ma lehulehu ma lalo 19,5%.
Inā wai naikokene, a laila ka mea, ua hūnāʻia i loko o kūikawā pahu. He mea pono i ka mea'ē aʻe e mālama mai i ka hopena o ka AaOIeIOUIeXAOAaIN me ka hehee ai. Wai naikokene ua waiho waho ma lalo o ka puʻe no i hiki i 350 MPa i loko o ka ipu buke o mai 80 a hiki i 450 nā lika.

Wai naikokene - pūnaewele a me ka hoʻohana '
Kūʻai, a hoʻohana i kēia huahana oe pono wale i loko o na keena me ka maikai hoʻokomo ea. Ua loa hiki ole ke waiho i loko o ka puni iho la ka makahiki. Makaukau o ka wai a naikokene i loko o ke keʻena hoʻokolohua, a koi kūikawā epekema no kona waiho waho pūnaewele i loko o pahu. Cryogenic ipu i hoʻolako pono me ka kūikawā manaʻo no ka puʻe kokua a me ka hooponopono ana o na puʻe. Ma lalo o maʻamau keia, ua pakele no lakou. I ole Ina e komo, e kāpae i a komo i loko o kekahi 'ē aʻe AaOIeIOUIeXAOAaIN me ka manaʻo koikoi ke ola noonoo. He mea hiki ole i ke kinowai naikokene ka hana 'ia ma luna o unprotected māhele o ke kino.
Ipu i loko o ka a waiho waho wai naikokene E e ia, a waiho ia ma ka pololei kūlana. Mai hoolilo i na ipu, a me ka hoahu ia ma luna o ko lākou mauʻaoʻao. Oe i hiki ole kū kaʻawale hoolilo aku i ehiku huewai i loaʻa ka waiwai. Inā 'oe i kekahi pilikia ma ka hoʻohanaʻana i ka ipu a me ka nohona kiwikā, laila pani i ka hoʻohana' ia koke.

Personal aiiay lako a (PPE)
Oe E maopopo leʻa heluhelu no ka maluhia a me ka waiwai o ka wai a naikokene mua ana. He pono, e hoomalu aku i nā maka, a me ka loa ikepili koʻikoʻi hapa o ke kino, mai na ohu o ka cryogenic wai. Makaukau o ka wai a naikokene ma lūmaua a me kona hoʻohana presupposes PPE. Pono e: he maka i ka pale kaua a me goggles, e wehe ai i-pono ili Loan, lōʻihi lole Awaits a me ka lole wāwae me ka cuffs, no hoi e pono ai ka maluhia kāmaʻa, oiaio hoi i ka poe i paka ipu pēpēʻana.
