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 samachita ndi zinthu zambiri. Katunduyu amapangitsa kuti ikhale yoyenera kusunga ndi kunyamula zinthu zosakhazikika, chifukwa zimachepetsa kuopsa kwa kuyaka kapena kuphulika. Kuphatikiza apo, chikhalidwe chake cha inert chimalola kuti chigwiritsidwe ntchito m'njira zosiyanasiyana zama labotale komanso ngati choziziritsa kuzinthu zofunikira pamagetsi.

3. Kukula pa Kutuluka kwa Nthunzi:

Akakumana ndi kutentha kwa chipinda, nayitrogeni wamadzimadzi amasanduka nthunzi msangamsanga ndipo amakula pafupifupi nthawi 700. Kukula uku kungapangitse mphamvu yamphamvu, kupanga madzi nayitrogeni yothandiza pamagwiritsidwe ntchito ngati rocket propulsion komanso ngati choziziritsa m'mafakitale.

Kagwiritsidwe Ntchito ka Liquid Nayitrogeni M'mafakitale Osiyanasiyana:

1. Makampani a Chakudya:

Nayitrogeni wamadzimadzi wasintha makampani azakudya popangitsa kuti pakhale zopanga zapadera zophikira. Nthawi zambiri amagwiritsidwa ntchito kuziziritsa zakudya mwachangu, kuteteza kutsitsimuka komanso kapangidwe kake. Njira imeneyi nthawi zambiri 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. Kuphatikiza apo, nayitrogeni wamadzimadzi amagwiritsidwa ntchito muzitsulo zopangira kutentha kwazitsulo kuti apititse patsogolo zinthu monga kuuma ndi kulimba. Kutentha kwake kotsika kumathandizanso kufota kwa zigawo ndikuthandizira 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 kuzizira mankhwala a rabara mofulumira panthawi ya vulcanization, zomwe zimapangitsa kuti tayala likhale lolimba komanso kuti likhale lolimba. Nayitrogeni wamadzimadzi amagwiritsidwanso ntchito m'malo oyesera injini kuti ayesere kuzizira kwambiri ndikuwunika momwe injini ikuyendera mumikhalidwe yotere.

Makhalidwe apadera a nayitrogeni wamadzimadzi amachititsa 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.
