Nitrous oxide, yomwe imadziwika kuti kuseka gasi kapena nitrous, ndi mankhwala, oxide wa nayitrogeni wokhala ndi formula N2O.

Chiyambi cha Zamalonda

Nitrous oxide, yomwe imadziwika kuti kuseka gasi kapena nitrous, ndi mankhwala, oxide wa nayitrogeni wokhala ndi formula N2O. Kutentha kwapakati, ndi gasi wopanda mtundu wosayaka, wokhala ndi fungo lachitsulo pang'ono ndi kukoma. Pakutentha kokwera, nitrous oxide ndi oxidizer yamphamvu yofanana ndi mpweya wa mamolekyulu.

Nitrous oxide imakhala ndi ntchito zambiri zamankhwala, makamaka popanga opaleshoni ndi mano, chifukwa chamankhwala ake komanso zochepetsera ululu. Dzina lake "gasi oseketsa", lopangidwa ndi Humphry Davy, ndi chifukwa cha zotsatira za euphoric pakuzikoka, katundu womwe wapangitsa kuti azigwiritsa ntchito mosangalala ngati mankhwala ophatikizira dissociative. Ili pa World Health Organisation's List of Essential Medicines, mankhwala othandiza kwambiri komanso otetezeka omwe amafunikira pazaumoyo.[2] Imagwiritsidwanso ntchito ngati oxidizer mu ma rocket propellants, komanso pa liwiro lamagalimoto kuti muwonjezere mphamvu zama injini.

Kufotokozera

Kugwiritsa ntchito

Zachipatala
Nitrous oxide yakhala ikugwiritsidwa ntchito popanga mano ndi opaleshoni, monga mankhwala ogonetsa komanso ochepetsa ululu, kuyambira 1844.

Zamagetsi
Amagwiritsidwa ntchito limodzi ndi silane poyika mpweya wa nthunzi wa zigawo za silicon nitride; amagwiritsidwanso ntchito mofulumira matenthedwe processing kukula apamwamba chipata oxides.

Kupaka & Kutumiza

Njira zothandizira zoyamba

KUPWETSA NTCHITO: Ngati zotsatira zoyipa zichitika, chotsani kumalo osakhudzidwa. Perekani mpweya wochita kupanga ngati ayi

kupuma. Ngati kupuma kuli kovuta, mpweya uyenera kuperekedwa ndi anthu oyenerera. Pezani nthawi yomweyo

chithandizo chamankhwala.

KUGWIRITSA NTCHITO KOPANDA: Ngati chisanu kapena kuzizira kwachitika, nthawi yomweyo tsukani ndi madzi ofunda ambiri (105-115 F; 41-46 C). MUSAGWIRITSE NTCHITO MADZI OTSATIRA. Ngati palibe madzi ofunda, kulungani bwinobwino mbali zomwe zakhudzidwa

mabulangete. Pezani chithandizo chamankhwala msanga.

KUGWIRITSA NTCHITO M'MASO: Tsukani maso ndi madzi ambiri.

KUGWIRITSA NTCHITO: Ngati munthu wameza kwambiri, pitani kuchipatala.

ZINDIKIRANI KWA NGWANA: Pokoka mpweya, ganizirani mpweya.

Ntchito

1.Magalimoto a rocket

Nitrous oxide imatha kugwiritsidwa ntchito ngati oxidizer mu mota ya rocket. Izi ndi zopindulitsa pa ma oxidiser ena chifukwa siwopanda poizoni, koma chifukwa cha kukhazikika kwake kutentha kwa firiji ndi kosavuta kusunga komanso otetezeka kunyamula ndege. Monga phindu lachiwiri, likhoza kuwonongeka mosavuta kupanga mpweya wopuma. Kuchulukira kwake kwakukulu ndi kusungirako kochepa (pamene kumasungidwa kutentha kochepa) kumapangitsa kuti ikhale yopikisana kwambiri ndi machitidwe osungidwa a mpweya wothamanga kwambiri.

2.Internal kuyaka injini - (Nitrous oxide injini)

Pa mpikisano wamagalimoto, nitrous oxide (yomwe nthawi zambiri imatchedwa "nitrous") imalola injini kuwotcha mafuta ambiri popereka mpweya wochulukirapo kuposa mpweya wokha, zomwe zimapangitsa kuyaka kwamphamvu kwambiri.

Nitrous oxide yamadzi agalimoto amasiyana pang'ono ndi nitrous oxide yamankhwala. Kachulukidwe kakang'ono ka sulfure dioxide (SO2) amawonjezeredwa kuti apewe kugwiritsa ntchito mankhwala osokoneza bongo. Kutsuka kangapo kudzera m'munsi (monga sodium hydroxide) kumatha kuchotsa izi, kumachepetsa zomwe zimawononga zomwe zimawonedwa pamene SO2 imatenthedwanso ndi kuyaka kukhala sulfuric acid, kupangitsa kuti utsi ukhale woyera.

3.Aerosol propellant

Mpweyawu umavomerezedwa kuti ugwiritsidwe ntchito ngati chowonjezera cha chakudya (wotchedwanso E942), makamaka ngati chopopera cha aerosol. Zomwe zimagwiritsidwa ntchito kwambiri m'nkhaniyi ndi m'zitini zokwapulidwa za aerosol, zopopera zophikira, komanso ngati mpweya wotulutsa mpweya womwe umagwiritsidwa ntchito pochotsa mpweya kuti aletse kukula kwa bakiteriya podzaza mapaketi a tchipisi ta mbatata ndi zakudya zina zokhwasula-khwasula.

Momwemonso, kuphika kutsitsi, komwe kumapangidwa kuchokera kumitundu yosiyanasiyana yamafuta ophatikizidwa ndi lecithin (emulsifier), kutha kugwiritsa ntchito nitrous oxide ngati propellant. Zopangira zina zomwe zimagwiritsidwa ntchito pophika kupopera ndi monga mowa wapachakudya ndi propane.

4.Medicine——–Nitrous oxide (mankhwala)

Nitrous oxide yakhala ikugwiritsidwa ntchito m'mano ndi opaleshoni, monga mankhwala oletsa ululu komanso ochepetsa ululu, kuyambira 1844.

Nitrous oxide ndi mankhwala ogonetsa ofooka wamba, motero nthawi zambiri sagwiritsidwa ntchito payekhapayekha, koma amagwiritsidwa ntchito ngati mpweya wonyamulira (wosakanizidwa ndi okosijeni) pamankhwala amphamvu kwambiri oletsa ululu monga sevoflurane kapena desflurane. Ili ndi ndende yocheperako ya alveolar ya 105% ndi gawo la magazi / gasi la 0.46. Kugwiritsa ntchito nitrous oxide mu anesthesia, komabe, kungapangitse chiopsezo cha postoperative nseru ndi kusanza.

Ku Britain ndi Canada, Entonox ndi Nitronox amagwiritsidwa ntchito kawirikawiri ndi ogwira ntchito ku ambulansi (kuphatikizapo osalembetsa) monga mpweya wofulumira komanso wothandiza kwambiri.

50% nitrous oxide ikhoza kuganiziridwa kuti igwiritsidwe ntchito ndi ophunzitsidwa omwe sali akatswiri oyankha chithandizo choyamba m'makonzedwe a prehospital, chifukwa cha kumasuka komanso chitetezo choperekera 50% nitrous oxide ngati mankhwala ochepetsa ululu. Kusinthika kofulumira kwa zotsatira zake kungalepheretsenso kuzindikiritsa matenda.

5.Kugwiritsa ntchito zosangalatsa

Kukoka kosangalatsa kwa nitrous oxide, ndi cholinga choyambitsa chisangalalo ndi/kapena kuyerekezera pang'ono, kudayamba ngati chodabwitsa kwa anthu apamwamba aku Britain mu 1799, omwe amadziwika kuti "maphwando amafuta akuseka".

Ku United Kingdom, pofika m’chaka cha 2014, akuti nitrous oxide ankagwiritsidwa ntchito ndi achinyamata pafupifupi theka la miliyoni m’malo ausiku, maphwando, ndi mapwando. Kuloledwa kwa kugwiritsira ntchito kumeneko kumasiyana kwambiri m’maiko, ndipo ngakhale mzinda ndi mzinda m’maiko ena.
