Kev tsim cov txheej txheem ntawm kev hloov ua ntej - txias kua nitrogen ceev - lub tshuab khov

1. Cov qauv siv hluav taws xob cuam tshuam nrog kev ua haujlwm ntawm cov khoom siv ceev ceev, tshwj xeeb tshaj yog rau lub tshuab ua kua nitrogen ceev khov uas tuaj yeem hloov ua ntej-txias.

Cov txheej txheem hauv qab:

2. Cov kua nitrogen yog inert, tsis muaj xim, tsis muaj ntxhiab, tsis yog -corrosive, tsis yog -flammable, thiab tsis tshua muaj heev -kub kua nitrogen. Nyob rau hauv ib txwm siab, qhov kub ntawm cov kua nitrogen yog

196 degree, 1m3 ntawm cov kua nitrogen tuaj yeem nthuav mus rau 696m

3 Ntshiab gaseous nitrogen ntawm 21 degree. Cov kua nitrogen (feem ntau sau ua ln2) yog cov kua nitrogen tsim ntawm qhov kub thiab txias. Lub boiling point ntawm nitrogen yog

Thaum 196 degree, kua nitrogen yuav tsim yog tias qhov kub thiab txias qis dua qhov no nyob rau hauv ib txwm atmospheric siab. Yog tias nws yog pressurized, kua nitrogen tuaj yeem tau ntawm qhov kub siab dua. Cov kua nitrogen sai- lub freezer tuaj yeem khov qhov nruab nrab kub ntawm ceev - cov khoom khov mus txog

18 degree, sai dhau ntawm cov dej khov siv lead ua thaj tsam hauv 30min (0

5 degree ib ntus) txhawm rau txo qhov poob ntawm cov as-ham thiab ua tiav qhov qub saj.

3. Tam sim no, lub txee - hom kua nitrogen ceev - lub freezer yog siv. Cov kua nitrogen nkag mus rau hauv lub freezer compartment thiab vaporized rau khov zaub mov. Tom qab qee lub sijhawm, nws raug tso tawm ncaj qha rau hauv huab cua. Kev siv tus nqi ntawm lub peev xwm txias ntawm vaporized kua nitrogen yog tsawg. Cov nyhuv ntawm khov tsis tuaj yeem lav.
