Cov yam ntxwv ntawm cov kua nitrogen:

1. Tsawg kub:

Ib qho ntawm cov khoom lag luam tshaj plaws ntawm cov kua nitrogen yog nws qhov tsawg tshaj plaws kub. Ntawm -195.8 degrees Celsius, nws muaj peev xwm sai heev txeej thaum muaj kev sib cuag. Cov cuab yeej no ua rau nws zoo tagnrho rau cov ntawv thov cryogenic, xws li khaws cov khoom siv roj ntsha, kom khov cov khoom noj khoom haus, thiab tsim cov zaub mov superconductors.

2. Inertness:

Ua kua nitrogen yog tshuaj inert, lub ntsiab lus nws tsis hnov ​​qab hau nrog cov tshuaj feem ntau. Cov cuab yeej no ua rau nws tsim nyog rau khaws cia thiab thauj cov khoom volatile, raws li nws txo qhov kev pheej hmoo ntawm kev sib txuas lossis tawg. Tsis tas li ntawd, nws cov inert speert tso cai rau nws siv rau hauv kev kuaj ntau yam thiab ua kom txias rau cov hluav taws xob hluav taws xob.

3. Kev nthuav dav thaum Evaporation:

Thaum raug rau chav sov, ua kua nitrogen sai evaporates thiab nthuav los ntawm ib qho kev sib xws li ntawm kwv yees li 700 zaug. Qhov kev nthuav dav no tuaj yeem tsim lub zog muaj zog, ua Ua kua nitrogen Pab tau rau cov ntawv thov xws li cov pob zeb ntxaij thiab ua kom txias hauv cov txheej txheem kev lag luam.

Siv cov kua nitrogen hauv ntau yam lag luam:

1. Kev lag luam khoom noj:

Ua kua Nitrogen tau hloov kho cov khoom noj khoom noj los ntawm kev ua kom cov khoom tsim tshwj xeeb. Nws yog ib qho siv tau siv cov khoom noj kom khov cov zaub mov sai, khaws cia lawv cov freshness thiab kev ntxhib los mos. Cov txheej txheem no feem ntau yog cov ua haujlwm hauv kev tsim cov khoom lag luam, cov khoom qab zib khov, thiab cov zaub mov khov-qhuav. Ib qho ntxiv, ua kua nitrogen yog siv rau zaub mov cia thiab tsheb thauj mus los txo cov khoom lwj thiab ua kom cov khoom lag luam zoo.

2. Kev lag luam kho mob thiab kev lag luam kws tshuaj):

Hauv thaj chaw kho mob, ua kua nitrogen pom dav hauv cov txheej txheem cryotheritapy, qhov uas tau siv rau khov thiab rhuav tshem cov ntaub so ntswg tsis zoo, xws li cov kab mob hlwb lossis cov hlwb. Nws tseem siv rau cov qauv cryopreserveservation ntawm kev kuaj cov phev, suav nrog cov phev, qe, thiab embryos rau kev kho fertility. Ntxiv mus, cov tuam txhab ua lag luam nitrogen thaum cov txheej txheem tshuaj yeeb tshuaj los tuav cov txheej txheem kub tsawg rau qee cov kev tawm tsam thiab khaws cov ntaub ntawv rhiab.

3. Kev tsim thiab engineering:

Ua kua nitrogen ua si lub luag haujlwm tseem ceeb hauv kev tsim khoom thiab Engineering Industries vim nws cov khoom cua txias. Nws yog siv raws li lub txias txias hauv ntau yam kev sib tsoo, xws li sib tsoo, txiav, thiab kev sib tsoo, kom tiv thaiv kev kub ntxhov thiab txuas ntxiv rau lub neej. Ib qho ntxiv, Ua kom cov neeg nitrogen yog ua haujlwm hauv cov txheej txheem cua sov hlau kom txhim kho cov khoom siv zoo li Hardness thiab kav ntev. Nws qhov kub thiab txias ntxiv kuj tau yooj yim ntawm cov ntsws-haum ntawm cov khoom thiab cov pa taus hauv kev tsim cov khoom ntsuas.

4. Tshawb nrhiav thiab kev txhim kho:

Hauv kev tshawb fawb lub chaw soj ntsuam, ua kua nitrogen pab ntau lub hom phiaj. Nws tau siv raws li lub txias rau superconducts hauv nucondle resonance (nmr) spectroscopy thiab sib nqus resonance tsom (MRI) tshuab. Tsis tas li ntawd, nws ua rau kev kawm ntawm tsawg-kub phenomena hauv physics thiab cov kev sim ua haujlwm. Nws qhov qis qis point kuj ua rau nws ua kom zoo tshaj plaws rau cryostats siv nyob rau hauv ntau yam kev thov tshawb fawb.

5. Kev lag luam Automotive:

Ua kua nitrogen pom cov ntawv thov hauv kev lag luam tsheb, tshwj xeeb hauv kev tsim cov log tsheb. Nws yog siv los khov cov roj hmab sib txuas sai sai thaum cov txheej txheem vulcanization, uas txhim kho lub log tsheb kom ruaj khov thiab ua haujlwm tau zoo. Cov kua nitrogen kuj tseem ua haujlwm hauv cov chaw kuaj cav kom simulate huab cua txias thiab ntsuas lub cav ua haujlwm nyob rau hauv cov xwm txheej zoo li no.

Cov kua nitrogen cov yam ntxwv tshwj xeeb ua rau nws muaj txiaj ntsig zoo nyob hauv ntau qhov kev lag luam. Nws qhov kub thiab txias, inertness, thiab nthuav dav thaum evaporation ua rau ntau yam kev siv, los ntawm kev tsim khoom noj rau cov txheej txheem kho mob thiab kev tshawb fawb tshawb fawb. Raws li kev siv thev naus laus zis, kev siv cov kua nitrogen zoo li yuav nthuav dav ntxiv, pab txhawb kev tsim kho tshiab thiab kev vam meej hauv ntau qhov chaw.
