Kev Taw Qhia rauCov Kav Dej Nqus Tsev rau cov kua nitrogen

Cov kav dej nqus tsev(VIPs) yog qhov tseem ceeb rau kev thauj mus los ntawm cov kua nitrogen zoo thiab muaj kev nyab xeeb, uas yog ib yam khoom siv dav dav thoob plaws ntau yam lag luam vim nws qhov kub qis heev ntawm -196 ° C (-320 ° F). Kev tswj cov kua nitrogen hauv nws lub xeev cryogenic xav tau cov thev naus laus zis rwb thaiv tsev siab heev, ua raucov kav dej nqus tsevqhov kev xaiv zoo tshaj plaws rau nws qhov chaw khaws cia thiab kev thauj mus los. Cov blog no tshawb nrhiav lub luag haujlwm tseem ceeb ntawm VIPs hauv kev siv cov kua nitrogen thiab lawv qhov tseem ceeb hauv cov txheej txheem kev lag luam.

Qhov Tseem Ceeb ntawm Kev Rwb Thaiv Tsev Hauv Kev Thauj Khoom Nitrogen Ua Kua

Cov kua nitrogen siv rau ntau yam kev siv, txij li kev khaws cia zaub mov mus rau kev khov cryogenic thiab kev tshawb fawb txog kev tshawb fawb. Yuav kom nws nyob hauv nws lub xeev kua, nws yuav tsum tau khaws cia thiab thauj mus rau qhov kub qis heev. Kev raug rau qhov kub siab dua tuaj yeem ua rau nws vaporize, ua rau cov khoom poob thiab muaj kev pheej hmoo ntawm kev nyab xeeb.Cov kav dej nqus tsevtau tsim los kom txo qhov kev hloov pauv thermal los ntawm kev tsim kom muaj qhov thaiv qhov nqus ntawm cov yeeb nkab sab hauv, uas nqa cov kua nitrogen, thiab cov yeeb nkab sab nraud. Qhov kev rwb thaiv tsev no yog qhov tseem ceeb hauv kev ua kom cov kua nitrogen nyob twj ywm ntawm qhov kub qis uas xav tau thaum lub sijhawm thauj mus los, khaws nws qhov kev ua haujlwm zoo thiab kev ua haujlwm zoo.

Cov ntawv thov ntawmCov Kav Dej Nqus Tsev nyob rau hauv Kev Kho Mob

Hauv kev kho mob, cov kua nitrogen feem ntau siv rau cryopreservation, uas cuam tshuam nrog kev khaws cov qauv tshuaj lom neeg xws li cov hlwb, cov ntaub so ntswg, thiab txawm tias cov kabmob ntawm qhov kub qis heev.Cov kav dej nqus tsevua lub luag haujlwm tseem ceeb hauv kev thauj cov kua nitrogen los ntawm cov thoob dej cia mus rau cov tub yees cryogenic, kom ntseeg tau tias qhov kub thiab txias tseem ruaj khov thiab sib xws. Qhov no yog qhov tseem ceeb rau kev tswj hwm qhov muaj sia nyob ntawm cov qauv tshuaj lom neeg, uas yuav raug cuam tshuam yog tias qhov kub hloov pauv. Qhov kev ntseeg siab ntawmcov kav dej nqus tsevhauv kev tswj cov qhov kub qis no yog qhov tseem ceeb rau kev vam meej ntawm cryopreservation hauv kev kho mob thiab kev tshawb fawb.

Kev Siv Cov Kua Nitrogen Hauv Kev Lag Luam Thiab Kev Ua Zaub Mov

Cov kev lag luam kuj tseem siv cov kua nitrogen rau cov ntawv thov xws li kev kho hlau, kev sib txuas, thiab cov txheej txheem inerting. Hauv kev ua zaub mov, cov kua nitrogen siv rau kev khov sai, uas khaws cov qauv, saj, thiab cov txiaj ntsig ntawm cov khoom noj.Cov kav dej nqus tsevyog qhov tseem ceeb rau cov txheej txheem no, kom ntseeg tau tias cov kua nitrogen raug xa mus zoo thiab ntawm qhov kub thiab txias. Qhov no txo ​​qhov kev pheej hmoo ntawm nitrogen vaporization, uas tuaj yeem ua rau qhov zoo thiab kev nyab xeeb ntawm kev lag luam thiab kev ua zaub mov ua haujlwm.

Kev nce qib hauv Kev Siv Tshuab Nqus Tsev Insulated Pipe

Cov kev nce qib uas txuas ntxiv mus hauvcov kav dej nqus tsevcov thev naus laus zis no ua rau lawv ua haujlwm tau zoo dua thiab ntseeg tau hauv kev siv cov kua nitrogen. Cov kev tsim kho tshiab suav nrog kev txhim kho cov txheej txheem tu lub tshuab nqus tsev, kev siv cov khoom siv ua haujlwm siab, thiab kev tsim cov kev daws teeb meem kav dej kom yooj yim dua los ua kom tau raws li cov kev xav tau ntawm ntau yam lag luam. Cov kev nce qib no tsis yog tsuas yog txhim kho kev ua haujlwm rwb thaiv tsev ntawm VIPs xwb tab sis kuj txo cov nqi ua haujlwm thiab kev siv hluav taws xob, ua rau lawv yog qhov kev daws teeb meem zoo dua rau cov lag luam uas vam khom cov kua nitrogen.
