Ua kua nitrogen: nitrogen roj hauv lub xeev ua kua. Inert, tsis muaj xim, tsw ntxhiab, tsis yog-corrosive, tsis-flamming, tsis tshua muaj neeg cryogenic kub. Cov ntaub ntawv nitrogen feem ntau ntawm cov cua (78.03% los ntawm ntim thiab 75.5% los ntawm qhov hnyav). Nitrogen tsis muaj zog thiab tsis txhawb kev sib txuas. Frostbite tshwm sim los ntawm ntau dhau endothermic tiv tauj thaum vaporization.
Ua kua nitrogen yog qhov chaw txias yooj yim. Vim nws cov khoom muaj txiaj ntsig, ua kua nitrogen tau yooj yim tau them ntau dua thiab ntau dua kev saib xyuas thiab paub los ntawm cov neeg. Nws tau muaj ntau dua thiab ntau dua dav siv hauv tsiaj tus txiv, kev lag luam kev kho mob, kev lag luam khoom noj, kev lag luam kev lag luam, thiab cryogenic tshawb fawb teb. Hauv cov khoom siv hluav taws xob, metallurgy, aerospace, machinery manufacturing thiab lwm yam ntawm daim ntawv thov tau nthuav dav thiab txhim kho.
Daim ntawv thov ntawm cov kua nitrogen nyob rau hauv cov zaub mov nrawm nrawm
Ua kua nitrogen khov raws li ib qho ntawm cov khoom noj kom khov khov kho, vim tias nws tuaj yeem paub cov khoom noj kom zoo nkauj Rov qab mus rau nws thawj lub xeev ntawm kev coj txawv txawv thiab kev ua noj ua haus thawj coj ua tus cwj pwm khov, yog li ntawd, nws qhia cov kev lag luam khov, nws qhia cov kev lag luam loj hauv kev lag luam sai. Piv nrog lwm txoj kev khov, ua kua nitrogen sai khov yog cov txiaj ntsig zoo hauv qab no:
(1) Kooj khov rau tus nqi (khov khov yog li 30-40 zaug sai dua li ib txwm khov kho): tuaj yeem ua cov zaub mov kom sai li cas los ntawm 0 ℃ ~ 5 ℃ Cov chaw tshawb nrhiav dej khov loj, kev tshawb fawb Cov neeg ua haujlwm tau ua tiav cov kev sim tseem ceeb hauv txoj kev hwm no.
(2) Txuas cov zaub mov ua rau lub cim ua kua ntawm cov kua nitrogen, aroma, saj thiab khoom noj khoom haus ua ntej ua tiav. Cov txiaj ntsig tau pom tias Areca catchu kho nrog kua nitrogen tau ntau dua chlorophyll cov ntsiab lus thiab ntxim nyiam ntxim nyiam.
(3) Cov Khoom Siv Qhuav Me: Feem ntau khov kev noj haus poob qis yog 3 ~ 6%, thiab ua kua nitrogen khov yuav raug tshem tawm mus rau 0.25 ~ 0.5%.
(4) Teeb cov cuab yeej xa khoom thiab siv hluav taws xob tsawg, yooj yim kom paub lub tshuab thiab lub rooj sib txoos sib dhos, txhim kho kev tsim khoom.
Tam sim no, muaj peb txoj kev ua kom khov ua kua ntawm cov pa nitrogen, uas yog khov thiab txias txias khov kho yog siv dav.
Kev thov cov kua nitrogen hauv dej haus ua
Tam sim no, ntau cov khoom lag luam hauv nitrogen lossis nitrogen thiab c02 sib xyaw ua ke hloov cov dej qab zib tsoos. Cov dej qab zib muaj pa roj carbonated uas muaj cov pa roj nitrogen tshwm sim tsawg dua cov muaj pa roj carbon dioxide ib leeg. Nitrogen tseem tsim nyog rau cov kaus poom tseem muaj dej haus xws li kua txiv thiab kua txiv. Qhov txiaj ntsig ntawm kev sau cov dej haus tsis muaj dej tsis sib xws nrog cov kua roj ua kua ntawm txhua qhov tuaj yeem thiab cov pa roj hauv lub zog cia ntawm lub neej lwj tau.
Daim ntawv thov ntawm cov kua nitrogen hauv kev khaws cia thiab khaws cov txiv hmab txiv ntoo thiab zaub
