Ua kua Nitrogen Vs. Dry Ice: Yam twg zoo dua rau cov khoom noj khov?

Thaum nws los txog rau qhov txias txias txias, kua nitrogen thiab dej khov qhuav yog ob qho kev xaiv nrov. Tab sis qhov twg yog qhov zoo dua rau cov khoom noj uas tsis muaj flash? Cov kua nitrogen yog txias dua thiab zoo dua rau kev khov, thaum cov dej khov qhuav yog yooj yim dua rau kev khaws cia khov thiab kev thauj mus los.

Nrog rau qhov kub ntawm -320 degree F (-196 degree), kua nitrogen freezes zaub mov yuav luag instantaneously. Qhov khov sai sai no txo ​​qis kev puas tsuaj rau cov khoom noj khoom haus thiab kev ntxhib los mos. Nws kuj inhibits ice crystal tsim, khaws cia zoo. Cov kua nitrogen tuaj yeem khov cov khoom noj sai sai rau qhov ntsuas kub zoo rau kev khaws cia ntev.

Txawm li cas los xij, kua nitrogen yuav tsum tau siv cov cuab yeej tshwj xeeb xws li blast freezers. Nws yuav tsum tau muab khaws cia thiab tswj kom zoo kom tsis txhob muaj kev phom sij xws li frostbite thiab ua tsis taus pa. Rau cov laj thawj no, cov kua nitrogen yog qhov zoo dua rau kev ceev ceev, ntim khov khov ntau dua li kev tswj xyuas kom khov rau lub sijhawm ntev.

Ntawm no, cov dej khov qhuav muaj qhov zoo. Ntawm -109.3 degree F (-78.5 degree), dej khov qhuav khaws cov khoom noj khov rau kev thauj mus los thiab khaws cia. Cov dej khov qhuav tso tawm cov pa cua txias CO2, pab tswj qhov kub thiab txias hauv cov thawv ntim khoom. Nws yog tus pheej yig thiab yooj yim siv. Cov dej khov qhuav tuaj yeem ntxiv ncaj qha rau cov pob khoom lossis cov thawv ntim kom cov khoom khov.

Thaum cov dej khov qhuav tsis khov sai npaum li cov kua nitrogen, nws ua tau zoo ntawm kev khaws cia khov rau lub sijhawm. Kev sib xyaw ua ke ob txoj hauv kev siv lawv lub zog tshwj xeeb. Cov kua nitrogen flash khov khaws cia zoo, thaum cov dej khov qhuav qhuav tswj kev ruaj khov.

Rau cov txiaj ntsig zoo tshaj plaws, tiv tauj peb cov kws tshaj lij txog kev sib xyaw ua kua nitrogen khov rau hauv koj cov txheej txheem. Peb tuaj yeem pom zoo cov cuab yeej ua kom khov cryogenic thiab cov txheej txheem kom khov cov zaub mov sai sai thaum ua kom lawv tshiab. Nrog rau txoj kev daws teeb meem khov, koj tuaj yeem xa cov khoom noj khov zoo rau koj cov neeg siv khoom.
