Liquid nitrogen: Nitrogen gasi iri mumvura. Inert, isina ruvara, isinganhuhwi, isingaore, isingabatike, yakanyanya cryogenic tembiricha. Nitrogen inoumba huwandu hwemhepo (78.03% nehuwandu uye 75.5% nehuremu). Nitrogen haishande uye haitsigire kupisa. Frostbite inokonzerwa nekunyanyisa endothermic kubata panguva yekupisa.
Liquid nitrogen inzvimbo inotonhora inotonhora. Nekuda kwehunhu hwayo hwakasiyana, nitrogen yemvura yakabhadharwa zvishoma nezvishoma uye ichizivikanwa nevanhu. Yave ichinyanya kushandiswa zvakanyanya mukupfuya mhuka, indasitiri yezvokurapa, indasitiri yechikafu, uye cryogenic research fields. Mune zvemagetsi, simbi, aerospace, kugadzira michina uye zvimwe zvinhu zvekushandisa zvave kuwedzera nekusimudzira.
Kushandiswa kwenitrogen yemvura muchikafu chinokurumidza kutonhora
Liquid nitrogen yakaomeswa seimwe yenzira dzakaomeswa dzekuunganidza yakagamuchirwa nebhizinesi rekugadzira chikafu, nekuti inogona kuona yakaderera-tembiricha cryogenic super inokurumidza chando, asi zvakare kuona chikamu chekuchinja kwegirazi kwechikafu chakaoma nechando, kuita kuti chikafu chinyunguduke. dzokera kumamiriro ayo ekutanga echikatyamadzo uye chepakutanga chikafu chekudya, yakanyanyisa kufambira mberi hunhu hwechikafu chakaomeswa nechando, Naizvozvo, inoratidza hutano hwakasiyana muindasitiri inokurumidza kutonhora. Kuenzaniswa nedzimwe nzira dzekuomesa nechando, mvura nitrogen inokurumidza kuomesa ine zvinotevera zviri pachena zvakanakira:
(1) Chiyero chekukurumidza kutonhora (chiyero chechando chinenge 30-40 nguva nekukurumidza kupfuura yakajairika nzira yechando): kugamuchirwa kwemvura nitrogen nekukurumidza kutonhora, kunogona kuita chikafu nekukurumidza kuburikidza ne0 ℃ ~ 5 ℃ yakakura ice crystal yekukura zone, chikafu chekutsvaga vashandi vakaita zviyedzo zvinobatsira panyaya iyi.
(2) Kubatanidza hunhu hwechikafu: nekuda kwenguva pfupi yechando yenitrogen yemvura, chikafu chakaomeswa nenitrogen yemvura chinogona kubatanidzwa neruvara, kunhuhwirira, kuravira uye kudya kunovaka muviri kusati kwagadziriswa kusvika pamwero mukuru. Mhedzisiro yacho yakaratidza kuti areca catechu yakarapwa nenitrogen yemvura yaive yakakwira chlorophyll yemukati uye yakanaka runako.
(3) diki yakaoma kushandiswa kwezvinhu: kazhinji yakaoma nechando kushandiswa kurasikirwa mwero ndeye 3 ~ 6%, uye mvura nitrogen yechando inogona kubviswa kusvika 0.25 ~ 0.5%.
(4) Seta kutumirwa kwemidziyo uye mashandisiro emagetsi akadzikira, zviri nyore kuona muchina uye mutsara wegungano unoshanda, kuvandudza chibereko.
Parizvino, kune nzira nhatu dzekukurumidza kuomeswa kwe nitrogen yemvura, dzinoti kupfapfaidza kutonhora, dip kutonhora uye kutonhora kwemhepo, pakati peiyo pfapfaidzo yechando inoshandiswa zvakanyanya.
Kushandiswa kwenitrogen yemvura mukugadzira chinwiwa
Iye zvino, vazhinji vanogadzira zvinwiwa vakagamuchira nitrogen kana nitrogen uye C02 mix-up panzvimbo yeC02 yechinyakare, kubata inflatable package drinks. Zvinwiwa zvakakwirira-carbonated zvakazadzwa nenitrogen zvakakonzera matambudziko mashoma pane izvo zvakazadzwa necarbon dioxide chete. Nitrogen inodiwawo pazvinwiwa zvichiri zvemumagaba zvakaita sewaini nemichero yemichero. Kubatsira kwekuzadza magaba echinwiwa asina-inflatable nenitrogen yemvura ndeyekuti iyo shoma shoma yenitrogen yemvura yakabayiwa inobvisa okisijeni kubva kumusoro kwegaba rega rega uye inopa inert yegasi munzvimbo yepamusoro yetangi rekuchengetedza, nekudaro kuwedzera hupenyu hwekuchengetedza. zvinoparara.
Kushandiswa kwenitrogen yemvura mukuchengetedza uye kuchengetedza michero nemiriwo
Liquid nitrogen kuchengetedza michero nemiriwo ine mukana wekudzora mhepo, inogona kugadzirisa zvekurima ne-zvigadzirwa mumwaka wepamusoro uye kunze kwemwaka wekupa uye kudiwa kupokana, kubvisa kurasikirwa kwekuchengetedza. Mhedzisiro yemhepo inogadzirisa ndeyekuvandudza kusanganiswa kwe nitrogen, kudzora chikamu che nitrogen, okisijeni uye C02 gasi, uye kuita kuti ibatanidzwe mune yakagadzikana mamiriro, yakaderera michero nemiriwo kufema simba, kunonoka kosi yekuibva, kuitira kuti. michero nemiriwo zvakabatana nemamiriro ekunze ekunhonga uye mari yekudya kwekutanga, inowedzera hutsva hwemichero nemiriwo.
Kushandiswa kwenitrogen yemvura mukugadzira nyama
Liquid nitrogen inogona kushandiswa kuvandudza huwandu hwezvigadzirwa mukuita skewering, kucheka kana kusanganisa nyama. Semuenzaniso, mukugadzirisa salami-mhando soseji, kushandiswa kwemvura nitrogen kunogona kuvandudza kuchengetwa kwemvura kwenyama, kudzivirira mafuta oxidation, kunatsiridza kucheka uye kunaka kwepamusoro. Inoshandiswa mukugadzirisa nyama yakadzokororwa senge nyama yekudya uye nyama yakachengetedzwa, haigoni kukurumidza kuparara kwezai jena uye kusimbisa kuchengetwa kwemvura kana nyama yavhiringidzika, asiwo inonyanya kubatsira pakubatanidza chimiro chakasiyana chechigadzirwa. Imwe nyama yenyama neyemvura nitrogen inokurumidza kutonhora, kwete chete mukubatana kwechigarire pakati pemhando inopisa nyama, gasi uye ive nechokwadi chehutano hwenyama uye runyararo. Mukugadzira tekinoroji, hapana chikonzero chekunetseka nezvekukanganisa kwekupisa kwemhando yenyama, uye kugadzirisa hakukanganiswe nekupisa kwezvinhu, nguva yekugadzira, mwaka zvinhu, asi zvakare inogona kuita iyo nzira yekugadzirisa pane yakaderera okisijeni chikamu chekumanikidza, mune imwe nzvimbo yekuwedzera hupenyu hwesherufu yezvigadzirwa.
Kushandiswa kwenitrogen yemvura mukugadzirisa chikafu pane cryogenic tembiricha
Cryogenic tembiricha kupwanya inzira yekupwanya kuita upfu pasi pekuita kwesimba rekunze, iro rakatonhodzwa kusvika kune tembiricha ye embrittlement point. Cryogenic tembiricha kupwanya chikafu hunyanzvi hwekugadzira chikafu hwakakura mumakore achangopfuura. Unyanzvi uhwu hwakakodzera kugadzira chikafu chine zvinhu zvakawanda zvinonhuhwirira, mafuta akawanda, shuga yakawanda uye gelatinous zvinhu zvakawanda. Cryogenic tembiricha yekupwanya neyemvura nitrogen kuraswa kurangwa, inogona kunyange zvinhu zvebhonzo, ganda, nyama, goko uye imwe-nguva imwe chete kupwanya, kuitira kuti iyo yakapedzwa idiki uye yakabatana nekudya kwayo kunobatsira. Kana Japan ichange yakaomeswa nechando nemvura yenitrogen yegungwa, chitin, muriwo, zvinonhuwirira, nezvimwewo muguyo, inogona kugadzira chigadzirwa chakapedzwa saizi yakanaka kusvika 100μm pazasi, uye yakakosha link kune yekutanga kudya kunovaka. Pamusoro pezvo, cryogenic tembiricha kupwanya nenitrogen yemvura inogona zvakare kupwanya zvinhu zvinonetsa kupwanya pane tembiricha yekamuri, zvinhu zvinonzwa kupisa uye zviri nyore kushata kana zvichipisa uye zviri nyore kuongorora. Pamusoro pezvo, mvura inonzi nitrogen inogona kushandiswa kupwanya nyama ine mafuta, miriwo yakanyorova uye zvimwe zvikafu zvinonetsa kupwanywa patembiricha yekamuri, uye zvinogona kushandiswa kugadzira chikafu chitsva chakabikwa.
Kushandiswa kwenitrogen yemvura mukurongedza chikafu
Imwe kambani yeLondon yakagadzira nzira iri nyore uye inoshanda yekuchengeta chikafu chiri chitsva nekuwedzera madonhwe mashoma emvura nitrogen pakurongedza. Kana nitrogen yemvura ichinyunguduka kuita gasi, huwandu hwayo hunowedzera nekukurumidza, nekuchimbidza kutsiva yakawanda yegasi rekutanga mubhegi rekurongedza, kubvisa kuparara kwechikafu kunokonzerwa neoxidation, nekudaro ichiwedzera zvakanyanya kutsva kwechikafu.
Kushandiswa kwenitrogen yemvura mukufambisa kwechikafu mufiriji
Kutakura kwefiriji chikamu chakakosha cheindasitiri yezvekudya. Kuvandudza hunyanzvi hwekuita nitrogen firiji, kukura zvitima zve nitrogen firiji, mota dzefiriji uye midziyo ine firiji ndiyo yakajairika kukura pari zvino. Kushandiswa kweiyo liquid nitrogen refrigeration system munyika dzakabudirira kwemakore akawanda kunoratidza kuti liquid nitrogen refrigeration system hunyanzvi hwekuchengetedza mufiriji hunogona kukwikwidza nemuchina wefiriji system mukutengeserana uye zvakare ndiko kukura kwekufambisa kwechikafu mufiriji.
Zvimwe zvinoshandiswa zve nitrogen yemvura muindasitiri yechikafu
Nekuda kwekuita kwefiriji yenitrogen yemvura, muto wezai, mvura inonhuhwirira, uye soy muto inogona kugadzirwa kuita yakasununguka uye kudirwa chikafu chakaomeswa nechando chinowanikwa nyore uye kugadzirwa zviri nyore. Pakukuya zvinonhuwira uye mvura inowedzerwa nezvokudya, zvakadai seshuga nelecithin, liquid nitrogen inobayiwa muguyo kuvhara mutengo uye kuwedzera goho rekukuya. Mhedzisiro yacho inoratidza kuti kuputsika kwemudhuri wemukume nekudzima nitrogen yakasanganiswa nekunyungudika kwekushisa kwakanyanya kune hunhu hwemichero yakanaka, kukwirira kwekupwanya kwemadziro, kukurumidza kukurumidza, kugadzikana kwemaitiro ehume uye kusasvibiswa.
