Nitrogen (N2)

Technical parameters

Nitrogen (N2) inoumba chikamu chikuru chemhepo yepasi, inoverengera 78.08% yehuwandu. Igasi risina ruvara, risinganhuhwi, risingarakidze, risiri muchetura uye rinenge rakazara inert gasi. Nitrogen haibatike uye inoonekwa segasi rinodzipa (kureva kuti, kufema nitrogen yakachena kunotadzisa muviri wemunhu oxygen). Nitrogen haishande mumakemikari. Inogona kuita nehydrogen kuumba ammonia pasi pekushisa kwepamusoro, kudzvinyirira kwakanyanya uye mamiriro ezvinhu anokonzera; inogona kusanganiswa neokisijeni kuumba nitric oxide pasi pemamiriro ekubuda. Nitrogen inowanzonzi gasi inert. Inoshandiswa mune dzimwe inert mhepo yekurapa simbi uye muma bulbs kudzivirira arcing, asi haisi kemikari inert. Chinhu chakakosha muhupenyu hwezvirimwa nemhuka, uye chikamu chemisanganiswa yakawanda inobatsira. Nitrogen inosanganiswa nesimbi dzakawanda kugadzira nitrides yakaoma, inogona kushandiswa sesimbi isingapfeki. Nhamba shoma ye nitrogen musimbi inodzivisa kukura kwezviyo pakupisa kwakanyanya uye ichawedzerawo simba remamwe masimbi. Inogonawo kushandiswa kugadzira nzvimbo dzakaoma pasimbi. Nitrogen inogona kushandiswa kugadzira ammonia, nitric acid, nitrate, cyanide, nezvimwewo; mukugadzira zvinoputika; kuzadza ma thermometers akakwirira-kupisa, incandescent bulbs; kugadzira zvinhu zvine inert kuchengetedza zvinhu, zvinoshandiswa mumabhokisi ekuomesa kana mabhegi egirovhosi. Liquid nitrogen panguva yechando chekudya; inoshandiswa sechinhu chinotonhodza murabhoritari. Nitrogen inofanira kuchengetwa yakatwasuka munzvimbo inofefetera, yakachengetedzeka uye isina mamiriro ekunze, uye tembiricha yekuchengetera haifanirwe kudarika 52°C. Panofanira kunge pasina zvinhu zvinobvira moto munzvimbo yekuchengetera uye gara kure nenzvimbo dzinowanzopinda nekubuda uye dzekubuda nechimbichimbi, uye hapana munyu kana zvimwe zvinokuvadza zviripo. Pamasilinda egasi asina kushandiswa, chivharo chevhavha uye chivharo chinobuda chinofanira kuvharwa zvakanaka, uye zvivharo zvisina chinhu zvinofanira kuchengetwa zvakasiyana kubva kumagetsi akazara. Dzivisa kuchengetedza zvakanyanya uye nguva yakareba yekuchengetedza, uye chengetedza marekodhi akanaka ekuchengetedza.

Application:

①Mumashandisirwo akasiyana-siyana ekuongorora chiridzwa:

Inotakura gasi yegesi chromatography, gasi rekutsigira reElectron Capture Detectors, Liquid Chromatography Mass Spectrometry, bvisa gasi reInductive Couple Plasma.

②Zvinhu:

1. Kuzadza magirobhu emwenje.
2. Mumhepo inorwisa mabhakitiriya uye musanganiswa wezviridzwa zvebiological applications.
3. Sechikamu mu Controlled Atmosphere Packaging uye Modified Atmosphere Packaging applications, 4. Calibration gasi musanganiswa wezvakatipoteredza monitoring systems, laser gasi musanganiswa.
5. Kupinza maitiro akawanda emakemikari anoomesa zvigadzirwa zvakasiyana-siyana kana zvinhu.

③Liquid nitrogen:

Kufanana nechando chakaoma, kushandiswa kukuru kwenitrogen yemvura yakaita sefiriji.
