HANGZHOU NUZHUO TECHNOLOGY GROUP CO., LTD.

Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv hauv Karnataka nyuam qhuav rov lees paub dua qhov kev txwv tsis pub siv cov kua nitrogen hauv cov khoom noj xws li cov ncuav qab zib haus luam yeeb thiab ice cream, uas tau pib thaum ntxov lub Tsib Hlis. Qhov kev txiav txim siab tau ua tom qab ib tug ntxhais hnub nyoog 12 xyoos los ntawm Bengaluru tau muaj lub qhov hauv nws lub plab tom qab nws noj mov ci uas muaj kua nitrogen.
Kev siv cov kua nitrogen hauv cov khoom noj uas tau npaj tiav lawm tau nce ntxiv nyob rau xyoo tas los no, nrog rau cov tshuaj siv los ua kom muaj pa luam yeeb rau qee cov khoom noj, khoom qab zib thiab dej qab zib.
Cov kua nitrogen hauv cov khoom noj yuav tsum tau ua tib zoo saib xyuas. Qhov no yog vim tias nitrogen yuav tsum tau txias kom txog qhov kub ntawm -195.8°C kom nws thiaj li ua kua. Piv txwv li, qhov kub hauv lub tub yees hauv tsev poob qis txog li -18°C lossis -20°C.
Cov pa roj uas tau muab tso rau hauv lub tub yees tuaj yeem ua rau mob frostbite yog tias nws kov cov tawv nqaij thiab cov kabmob. Cov pa roj nitrogen ua rau cov nqaij khov sai heev, yog li nws tuaj yeem siv rau hauv cov txheej txheem kho mob kom rhuav tshem thiab tshem tawm cov pob khaus lossis cov nqaij mob qog noj ntshav. Thaum nitrogen nkag mus rau hauv lub cev, nws sai sai hloov mus ua roj thaum qhov kub nce siab. Qhov piv ntawm kev nthuav dav ntawm cov pa roj nitrogen ntawm 20 degrees Celsius yog 1: 694, uas txhais tau tias 1 liv ntawm cov pa roj nitrogen tuaj yeem nthuav dav mus rau 694 liv ntawm nitrogen ntawm 20 degrees Celsius. Qhov kev nthuav dav sai no tuaj yeem ua rau lub plab zom mov tawg.
"Vim tias nws tsis muaj xim thiab tsis muaj ntxhiab, tib neeg yuav raug nws yam tsis paub. Raws li ntau lub tsev noj mov siv cov kua nitrogen, tib neeg yuav tsum paub txog cov xwm txheej tsis tshua muaj no thiab ua raws li cov lus qhia. Txawm hais tias tsis tshua muaj, qee zaum nws tuaj yeem ua rau muaj kev phom sij loj heev." Dr. Atul Gogia, tus kws pab tswv yim laus, chav kho mob sab hauv, Sir Gangaram Tsev Kho Mob hais.
Cov kua nitrogen yuav tsum tau ua tib zoo saib xyuas, thiab cov neeg ua haujlwm yuav tsum siv cov khoom siv tiv thaiv kom tsis txhob raug mob thaum lub sijhawm ua zaub mov. Cov neeg uas noj zaub mov thiab dej haus uas muaj kua nitrogen yuav tsum xyuas kom meej tias cov nitrogen tau ploj mus tag ua ntej noj. "Kua nitrogen ... yog tias tsis ua haujlwm lossis noj tsis raug, tuaj yeem ua rau puas tsuaj rau daim tawv nqaij thiab cov kabmob sab hauv vim qhov kub qis heev uas kua nitrogen tuaj yeem tswj tau. Yog li ntawd, kua nitrogen thiab dej khov qhuav yuav tsum tsis txhob noj ncaj qha lossis kov ncaj qha rau daim tawv nqaij uas raug tshav ntuj. ", US Food and Drug Administration tau hais hauv ib daim ntawv tshaj tawm. Nws kuj tau hais kom cov khw muag khoom noj tsis txhob siv nws ua ntej muab zaub mov.
Cov roj tsuas yog siv rau kev ua noj ua haus hauv qhov chaw uas muaj cua nkag tau zoo xwb. Qhov no yog vim tias cov pa nitrogen tuaj yeem ua rau cov pa oxygen hauv huab cua hloov chaw, ua rau hypoxia thiab asphyxiation. Thiab vim tias nws tsis muaj xim thiab tsis muaj ntxhiab, kev nrhiav cov pa roj yuav tsis yooj yim.
Nitrogen yog ib qho roj inert, txhais tau tias nws tsis ua rau muaj ntau yam tshuaj, thiab nws siv los tswj cov khoom noj uas tau ntim rau hauv lub hnab kom tshiab. Piv txwv li, thaum lub hnab qos yaj ywm muaj nitrogen, nws yuav tshem cov pa oxygen uas nws muaj. Cov khoom noj feem ntau ua rau muaj pa oxygen thiab lwj. Qhov no ua rau cov khoom siv khaws cia ntev dua.
Qhov thib ob, nws yog siv rau hauv daim ntawv kua kom khov cov khoom noj tshiab xws li nqaij, nqaij qaib thiab cov khoom noj mis nyuj sai sai. Kev khov cov khoom noj uas muaj nitrogen pheej yig heev piv rau kev khov ib txwm vim tias cov khoom noj ntau tuaj yeem khov tau hauv ob peb feeb xwb. Kev siv nitrogen tiv thaiv kev tsim cov dej khov, uas tuaj yeem ua rau cov hlwb puas tsuaj thiab ua rau cov khoom noj qhuav.
Ob qho kev siv txuj ci no raug tso cai raws li txoj cai kev nyab xeeb zaub mov ntawm lub tebchaws, uas tso cai rau kev siv nitrogen hauv ntau yam khoom noj, suav nrog cov khoom noj mis nyuj fermented, kas fes thiab tshuaj yej uas npaj txhij haus, kua txiv hmab txiv ntoo, thiab txiv hmab txiv ntoo tev thiab txiav. Daim nqi tsis tau hais meej txog kev siv cov kua nitrogen hauv cov khoom tiav.
Anonna Dutt yog tus thawj coj xov xwm kev noj qab haus huv rau The Indian Express. Nws tau hais txog ntau yam, txij li qhov kev nce ntxiv ntawm cov kab mob tsis sib kis xws li ntshav qab zib thiab ntshav siab mus rau qhov teeb meem ntawm cov kab mob sib kis.
