Nayitrogeni Wamadzimadzi: Katundu ndi Ntchito M'mafakitale Osiyanasiyana
Nayitrogeni wamadzimadzindi madzi opanda mtundu, osanunkhiza, komanso osayaka omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana. Amapangidwa ndi liquefying atmospheric nitrogen, yomwe ndi mpweya wochuluka kwambiri padziko lapansi. Nayitrojeni wamadzimadzi amakhala ndi kuwira kwa -195.8 degrees Celsius, kapena -320.4 degrees Fahrenheit. Izi zimapangitsa kukhala chinthu chozizira kwambiri chomwe chimapezeka nthawi zambiri.
Makhalidwe a Liquid Nayitrojeni:
1. Kutentha kochepa:
Chimodzi mwazinthu zodziwika bwino za nayitrogeni wamadzimadzi ndi kutentha kwake kotsika kwambiri. Pa -195.8 digiri Celsius, imatha kuzizira kwambiri zinthu zikakhudza. Katunduyu amapangitsa kuti ikhale yabwino kugwiritsa ntchito cryogenic, monga kusunga zitsanzo zachilengedwe, kuzizira kwazakudya, ndikupanga ma superconductors.
2. Kusalankhula:
Nayitrogeni wamadzimadzi ndi wolowera mumankhwala, kutanthauza kuti samakhudzidwa ndi zinthu zambiri. Katunduyu amapangitsa kuti ikhale yoyenera kusungirako ndikunyamula zinthu zosakhazikika, chifukwa zimachepetsa chiopsezo cha kuyaka kapena kuphulika. Kuphatikiza apo, chikhalidwe chake cha inert chimalola kuti chigwiritsidwe ntchito m'njira zosiyanasiyana zama labotale komanso ngati choziziritsa kuzinthu zodziwika bwino zamagetsi.
3. Kukula pa Kutuluka kwa Evaporation:
Akakumana ndi kutentha kwa chipinda, nayitrogeni wamadzimadzi amasanduka nthunzi msangamsanga ndipo amakula pafupifupi nthawi 700. Kukulaku kumatha kupanga mphamvu yamphamvu, kupangitsa kuti nayitrogeni wamadzimadzi akhale wofunikira pakugwiritsa ntchito ngati rocket propulsion komanso ngati choziziritsa m'mafakitale.
Kugwiritsa Ntchito Liquid Nayitrogeni M'mafakitale Osiyanasiyana:
1. Makampani a Chakudya:
Nayitrogeni wamadzimadzi wasintha makampani azakudya pothandizira kupanga zopanga zapadera zazakudya. Nthawi zambiri amagwiritsidwa ntchito kuziziritsa zakudya mwachangu, kuteteza kutsitsimuka komanso kapangidwe kake. Njira imeneyi imagwiritsidwa ntchito popanga ayisikilimu, maswiti oundana, komanso zakudya zowuma. Kuphatikiza apo, nayitrogeni wamadzimadzi amagwiritsidwa ntchito posungira chakudya komanso kunyamula kuti achepetse kuwonongeka ndikusunga zinthu zabwino.
2. Makampani a Zamankhwala ndi Mankhwala:
M'zachipatala, nayitrogeni wamadzimadzi amagwiritsidwa ntchito kwambiri m'machitidwe a cryotherapy, pomwe amagwiritsidwa ntchito poundana ndikuwononga minyewa yachilendo, monga njerewere kapena ma cell a precancerous. Amagwiritsidwanso ntchito ngati cryopreservation of biological samples, kuphatikiza umuna, mazira, ndi miluza pochizira kubereka. Kuphatikiza apo, makampani opanga mankhwala amagwiritsa ntchito nayitrogeni wamadzimadzi panthawi yopanga mankhwala kuti asunge kutentha komwe kumafunikira kuti achitepo kanthu ndikusunga zinthu zofunikira.
3. Kupanga ndi Uinjiniya:
Nayitrogeni wamadzimadzi amagwira ntchito yofunika kwambiri m'mafakitale opangira ndi uinjiniya chifukwa cha kuzizira kwake. Amagwiritsidwa ntchito ngati choziziritsa munjira zosiyanasiyana zamakina, monga kugaya, kudula, ndi kubowola, kupewa kutenthedwa ndi kukulitsa moyo wa zida. Kuonjezera apo, nayitrogeni wamadzimadzi amagwiritsidwa ntchito pochiritsa kutentha kwazitsulo kuti apititse patsogolo zinthu monga kuuma ndi kulimba. Kutentha kwake kotsika kumathandizanso kuti zidulidwe zing'onozing'ono zitheke komanso zimathandizira kupanga magawo olondola.
4. Kafukufuku ndi Chitukuko:
M'ma laboratories ofufuza, nayitrogeni wamadzimadzi amagwira ntchito zingapo. Amagwiritsidwa ntchito ngati choziziritsa kukhosi kwa maginito apamwamba kwambiri pamakina a nyukiliya maginito resonance (NMR) ndi makina oyerekeza a maginito (MRI). Kuphatikiza apo, imathandizira kuphunzira za zochitika zotsika kutentha muzoyeserera za physics ndi chemistry. Kutentha kwake kocheperako kumapangitsanso kukhala koziziritsa bwino kwa ma cryostats omwe amagwiritsidwa ntchito pazinthu zosiyanasiyana zasayansi.
5. Makampani Oyendetsa Magalimoto:
Nayitrogeni wamadzimadzi amapeza ntchito m'makampani opanga magalimoto, makamaka popanga matayala. Amagwiritsidwa ntchito kuziziritsa mphira mwachangu panthawi yavulcanization, zomwe zimapangitsa kuti tayala likhale lolimba komanso kuti lizigwira ntchito. Nayitrogeni wamadzimadzi amagwiritsidwanso ntchito m'malo oyesera injini kuti ayesere kuzizira kwambiri ndikuwunika momwe injini ikuyendera mumikhalidwe yotere.
Makhalidwe apadera a nayitrogeni wamadzimadzi amapangitsa kuti ikhale yothandiza kwambiri m'mafakitale osiyanasiyana. Kutentha kwake kocheperako, kusakhazikika kwake, komanso kufutukuka kwake kumapangitsa kuti pakhale ntchito zosiyanasiyana, kuyambira kupanga chakudya kupita ku njira zamankhwala ndi kafukufuku wasayansi. Pamene ukadaulo ukupita patsogolo, kugwiritsa ntchito nayitrogeni wamadzimadzi kukuyembekezeka kukulirakulira, zomwe zikuthandizira kukulitsa luso komanso kupita patsogolo m'magawo ambiri.
