Nitrous oxide, inozivikanwa segasi rinoseka kana kuti nitrous, ikemikari inosanganiswa, oxide yenitrogen ine fomura N2O

Nhanganyaya yeChigadzirwa

Nitrous oxide, inozivikanwa segasi rekuseka kana kuti nitrous, ikemikari, oxide yenitrogen ine fomura N2O. Patembiricha yemumba, igesi risingatsve risina ruvara, rine hwema hwesimbi uye kuravira zvishoma. Patembiricha yakakwira, nitrous oxide isimba guru re oxidizer rakafanana neokisijeni yemamorekuru.

Nitrous oxide inoshandiswa zvakanyanya mukurapa, kunyanya mukuvhiya nekurapa mazino, nekuda kwemhedzisiro yayo yekunyaradza marwadzo uye kuderedza marwadzo. Zita rayo rekuti "gasi rinoseka", rakagadzirwa naHumphry Davy, rinokonzerwa nemhedzisiro inofadza painofema, chinhu chakaita kuti ishandiswe mukuvaraidza semushonga wekunyaradza marwadzo. Iri paWorld Health Organization's List of Essential Medicines, mishonga inoshanda uye yakachengeteka inodiwa muhutano.[2] Inoshandiswawo semushonga wekuoxidizer muzvifambiso zveroketi, uye mumitambo yemotokari kuwedzera simba remagetsi einjini.

Tsanangudzo

Kushandiswa

Zvekurapa
Nitrous oxide yave ichishandiswa mukurapa mazino nekuvhiya, semushonga wekurwadziwa uye wekurwadziwa kwemusoro, kubvira muna 1844.

Zvemagetsi
Inoshandiswa pamwe chete ne silane pakuburitsa makemikari e silicon nitride layers; inoshandiswawo mukupisa nekukurumidza kuti ikure ma gate oxides emhando yepamusoro.

Kurongedza & Kutumira

Mashandisirwo

1.Mota dzeroketi

Nitrous oxide inogona kushandiswa se oxidizer mu rocket motor. Izvi zvinobatsira kupfuura mamwe ma oxidiser nekuti haisi chete isina chepfu, asi nekuda kwekugadzikana kwayo patembiricha yemumba, iri nyorewo kuichengeta uye yakachengeteka kutakura kana yabhururuka. Seimwe yekubatsira kwayo, inogona kuora nyore nyore kuti igadzire mhepo inofema. Kuwanda kwayo kwakanyanya uye kumanikidzwa kwayo kushoma (kana yakachengetedzwa patembiricha yakaderera) zvinoita kuti ikwanise kukwikwidzana zvakanyanya nemasisitimu emagasi ane pressure yakawanda akachengetwa.

2. Injini yekupisa mukati —(Injini yeNitrous oxide)

Mukufambisa mota, nitrous oxide (inowanzonzi "nitrous") inobvumira injini kupisa mafuta akawanda nekupa okisijeni yakawanda kupfuura mhepo chete, zvichikonzera kupisa kwakasimba.

Nitrous oxide yemhando yemotokari yakasiyana zvishoma nenitrous oxide yemhando yekurapa. Hushoma hwesulfur dioxide (SO2) hunowedzerwa kudzivirira kushandiswa zvisina kunaka kwezvinodhaka. Kushambidzwa kakawanda kuburikidza nebase (senge sodium hydroxide) kunogona kubvisa izvi, zvichideredza hunhu hwekuora hunoonekwa kana SO2 ikawedzerwa oxidised panguva yekupiswa kuita sulfuric acid, zvichiita kuti utsi huve hwakachena.

3. Chinopfuta mhepo

Gasi iri rinotenderwa kushandiswa sechikafu chinowedzera (chinozivikanwawo seE942), kunyanya semushonga wekufema unopisa. Mashandisirwo aro anonyanya kuitwa muzvinhu izvi ndeemumagaba emushonga wekufema unopisa, maspray ekubika, uye segasi risingashande rinoshandiswa kubvisa okisijeni kuitira kudzivirira kukura kwemabhakitiriya pakuzadza mapakeji emachipisi embatatisi nezvimwe zvekudya zvakafanana.

Saizvozvowo, cooking spray, iyo inogadzirwa nemafuta akasiyana-siyana akasanganiswa ne lecithin (emulsifier), inogona kushandisa nitrous oxide se propellant. Mamwe ma propellant anoshandiswa mu cooking spray anosanganisira food-grade alcohol ne propane.

4. Mushonga——–Nitrous oxide (mushonga)

Nitrous oxide yave ichishandiswa mukurapa mazino nekuvhiya, semushonga wekurwadziwa uye wekurwadziwa kwemusoro, kubvira muna 1844.

Nitrous oxide mushonga unonyaradza marwadzo usina simba, saka hauwanzo shandiswa wega mukurapa marwadzo, asi unoshandiswa segasi rinotakura marwadzo (rakasanganiswa neokisijeni) pamishonga ine simba yakaita sesevoflurane kana desflurane. Ine huwandu hushoma hwe alveolar concentration hwe105% uye chiyero cheropa/gas partition che0.46. Zvisinei, kushandiswa kwe nitrous oxide mukurapa marwadzo kunogona kuwedzera njodzi yekusvotwa nekurutsa mushure mekuvhiyiwa.

MuBritain neCanada, Entonox neNitronox zvinowanzo shandiswa nevashandi veamburenzi (kusanganisira vanachiremba vasina kunyoreswa) segasi rinonyaradza marwadzo nekukurumidza uye rinoshanda zvikuru.

50% nitrous oxide inogona kufungwa kuti ishandiswe nevanopa rubatsiro rwekutanga vasina hunyanzvi munzvimbo dzisati dzaenda kuchipatara, tichifunga kuti zviri nyore uye zvakachengeteka kupa 50% nitrous oxide semushonga unonyaradza marwadzo. Kukurumidza kudzoka kwemhedzisiro yayo kunogonawo kudzivirira kuti isaonekwe.

5. Kushandiswa kwevaraidzo

Kufema nitrous oxide nekunakidzwa, nechinangwa chekukonzera kufara uye/kana kuona zvinhu zvisipo, kwakatanga sechiitiko chevanhu vepamusoro vekuBritain muna 1799, chinozivikanwa se "mapati egasi ekuseka".

MuUnited Kingdom, kubva muna 2014, nitrous oxide yaifungidzirwa kuti yaishandiswa nevechidiki vanosvika hafu yemiriyoni pamitambo yemanheru, mitambo, nemapati. Mitemo yekushandisa iyoyo inosiyana zvikuru kubva munyika nenyika, uye kunyange kubva muguta neguta mune dzimwe nyika.
