Ruwa nitrogen da zazzabi

Liquid nitrogen ne m abu wanda takamaiman yawa ne 0,808 g / cm³. Wannan - daya daga cikin tari yanayin a cikin abin da na iya zama nitrogen, tafasar zafin jiki na -195,75 C. Liquid nitrogen ne ba mai guba da ke fashewa-hujja.

A siffa daga cikin aiki da kuma ajiya na ruwa nitrogen ne cewa a lokacin da mai tsanani, shi yana faɗaɗa ƙwarai, misali, da yawan zafin jiki ne tãyar kawai zuwa 20 C, daya lita na kayan da aka kafa game da lita 700 gas. Saboda haka, ajiya da kuma harkokin sufuri na musamman kwantena suna amfani, da ake kira Dewar tasoshin wanda samar da injin kadaici.

Liquid nitrogen da aka iske quite yadu amfani a fannoni daban daban na mutum aiki, a mutunta mutane da yawa, wannan kamu na amfani saboda wannan dukiya, da yawan zafin jiki na ruwa nitrogen. Ana amfani da a masana'antu inda shi wajibi ne cikin yin amfani da fasahar cryogenic na yankan karafa. A sosai low zafin jiki na ruwa nitrogen damar ta yin amfani da zurfin-daskararre, da kuma a cikin wannan filin da shi ne ya dace duka biyu inorganic kayan da kwayoyin, ciki har da rayayyun kwayoyin halitta.

Akwai wasu aikace-aikace sun hada da: wuta fada da sanyaya daban-daban raka'a da fasaha na'urorin, cryopreservation na sel overclocking.

A yanayi matsa lamba, ruwa nitrogen da zazzabi kasa da sandaro zafin jiki na oxygen a 10 digiri, duk da haka, kamar yadda mai mulkin, a kan jirgin ruwa ganuwar za a iya lura condensate abu precipitate.

By nagarta da cewa tafasar batu na nitrogen da yake a cikin ruwa a jihar - 195,8 C, wanda shi ne m fiye da na ruwa oxygen a cikin abin da shi ne - 183 C, da sakamakon da hulda ruwa iska wadãtar da oxygen sosai da sauri. Wannan kuma bayyana bambanci a cikin yanayin zafi da kuma mafi tsanani da danshin ruwa nitrogen, idan aka kwatanta da ruwa oxygen.

Kusan duk wani zazzabi da ya wuce nuna alama ga ruwa nitrogen, za a iya lura a lokacin da gudanar da wadannan gwaji. Da muhimmanci ga wannan aluminum block aka sanyaya, idan ta hankali drip ruwa iska.

A zamani da fasaha da yawan zafin jiki na ruwa nitrogen a matsayin asali dukiya na kayan sa tartsatsi amfani a lantarki da kuma lantarki masana'antu na semiconductors, wanda game da shi samu abin dogara sanyaya.

A wannan manufa, da kuma aikace-aikace tushen abu kamar wani bangaren na daban-daban wuta garwayayye. A kan aiwatar da extinguishing nitrogen evaporates sosai da sauri kuma, ta haka ne, displaces da oxygen, sakamakon ƙarshe na samun da oxygen zuwa ga wuta wuta wuta da aka sarrafa da kuma tsaya a nan gaba daya. Saboda wannan sakamako yau nitrogen wuta-yãƙi zaton mafi tasiri fiye da carbon-dioxide. Lokacin amfani da wannan fasahar, a babban mataki na adana dũkiya.

A general, da sakamako daga cikin ruwa nitrogen yana da ikon saka idanu kusan kowane, idan kun jũya ta da hankali ga miƙa movie-kamar, amfani a yin fim na zamani da fina-finai. Alal misali, a cikin fim din 'The Terminator' yadu used effects samu ta hanyar yin amfani da ruwa nitrogen (Frames, wanda ya nuna nan take daskarewa wuraren). Amma wannan sakamako zai iya zama fiye da yawan zama cikin jiki. Alal misali, low zazzabi nitrogen damar ta yin amfani ga m sanyi analgesic hali. Wannan za mu iya sau da yawa kalla a lokacin wani wasa taron, a lokacin da wani dan wasa da aka ji rauni, da kuma taimakon farko ta cikin gida aerosol maganin sa barci.

More m, idan ba dama, yanzu tsaye da yin amfani da abu a matsayin wajen daskarewa halittu masu rai, tare da view ga m defrosting, da kuma kiyaye nazarin halittu Properties.

A lokaci guda, duka a cikin Amurka da kuma a Rasha, akwai riga kamfanonin da suke kudi shiga a cikin cryogenic daskarewa na mutane da dabbobi.
