Puas yog Nitrogen ua hluav taws xob?
Txheem
Nitrogen tsis yog hlau thiab tuaj yeem ua ntau hom. Ntau tus neeg xav paub seb puas muaj nitrogen yog qhov ua rau cov dej ntws ntawm hluav taws xob. Nws yog ib lo lus nug ncaj ncees, pom tias nitrogen muaj txiaj ntsig hauv kev ua haujlwm ntawm lub teeb.
Nitrogen yog ib qho khoom siv insulating thiab tsis tuaj yeem ua hluav taws xob. Nws siv nyob rau hauv lub teeb ntau lawm lov down voltage thiab tiv thaiv arcing. Qee lub sij hawm tsis tshua muaj, cov tshuaj no yuav dhau los ua tus neeg xyuas pib.
Kuv yuav piav ntxiv.
thawj kauj ruam
Kuv yuav tsum pib nrog qee cov ntaub ntawv hais txog nitrogen.
Nitrogen yog ib qho tseem ceeb tshaj plaws rau cov kab mob muaj sia. Nyob rau hauv qhov xwm txheej, nws muaj nyob rau hauv cov pa roj, kua, thiab khoom siv. Nws tsim cov tshuaj sib xyaw nrog hydrogen, oxygen, thiab hlau.
Lub valence electron naj npawb ntawm nitrogen yog tsib. Tus lej ntawd ua rau nws nyuaj rau lub caij ua hluav taws xob vim tias lub atom lub hauv paus nruj nreem khi cov electrons ntawm nws. Yog li, nws cov ntawv gaseous, kua thiab khoom tsis tuaj yeem ua hluav taws xob.
Cov kws tshawb fawb tau pom cov nitrogen tebchaw xws li nitric oxide thiab nitrogen dioxide hnov mob nrog hluav taws xob. Qhov ntawd tsis tau txhais hais tias cov tebchaw tau nce conductivity.
Tshwj xeeb tshaj yog, nitric oxide tuaj yeem tsim los ntawm xob laim. Ob peb nitrogen dioxide tebchaw kuj yuav raug tsim ib txhij thaum lub sijhawm ua haujlwm. Txawm li cas los xij, ob qho tib si molecules tsis ua hluav taws xob.
Qhov tseeb, muaj peb lub sijhawm uas nitrogen tuaj yeem xa cov hluav taws xob tam sim no, uas kuv yuav piav qhia hauv qab no hauv tsab xov xwm.
Kev siv Nitrogen hauv Kev Lag Luam Hluav Taws Xob
Nitrogen yog siv nyob rau hauv tungsten filament teeb.
Hom teeb pom kev zoo li no yog tsim los ntawm cov hlau nyias (filament) thiab cov khoom sib xyaw ua ke ntawm cov pa roj uas muaj nyob rau hauv lub iav sab nrauv. Cov hlau, thaum hluav taws xob ntws los ntawm, ci ntsa iab. Cov roj muab tub lim accentuate lub ci ntsa iab txaus kom teeb ib chav.
Nitrogen tau ua ke nrog argon (ib qho roj zoo) hauv cov qij no.
Vim li cas Nitrogen siv nyob rau hauv lub teeb?
Txij li thaum lub caij yog ib qho insulator, nws yuav zoo li khib siv nws hauv lub teeb. Txawm li cas los xij, muaj ib qho laj thawj yooj yim.
Nitrogen muaj peb yam zoo:
- Nws dismantle qhov voltage ntws.
- Nws tsis pub arcing rau ntawm filament.
- Nws tsis suav nrog oxygen.
Los ntawm dismantling lub voltage, nitrogen tiv thaiv overheating.
Tsis tas li ntawd, vim nws cov arcing-tiv thaiv cov khoom, ntau qhov ntau ntawm nitrogen yog suav nrog hauv kev sib xyaw rau cov teeb uas tsim kom muaj hluav taws xob ntau dua.
Oxygen tuaj yeem yooj yim cuam tshuam nrog cov nqi hluav taws xob thiab cuam tshuam qhov ntws ntawm cov hluav taws xob tam sim no, ua rau nitrogen ntxiv rau qhov teeb pom kev zoo no.
Cov rooj plaub uas Nitrogen tuaj yeem ua hluav taws xob
Raws li txoj cai dav dav, ionization tsub kom cov conductivity ntawm cov khoom.
Yog li, yog tias peb dhau lub peev xwm ionization ntawm nitrogen lossis nitrogen compound, nws yuav ua hluav taws xob.
Ntawm tib daim ntawv, peb tuaj yeem tsim thermal ionization. Lub valence electrons tej zaum yuav raug tso tawm los ntawm lub nucleus lub hwj chim thiab tig mus rau hauv ib tug tam sim no. Qhov ntawd tuaj yeem tshwm sim los ntawm kev siv qhov kub thiab txias.
Nyob rau hauv nitrogen cov pa roj, nws muaj peev xwm hloov cov electrons dawb rau hauv ib qho me me tam sim no. Yog tias peb siv qhov hluav taws xob hnyav heev, muaj lub caij nyoog peb yuav tsim kom muaj hluav taws xob.
Qhov kawg lub caij nyoog rau nitrogen los ua conductive yog nyob rau hauv nws plaub lub xeev ntawm teeb meem: plasma. Txhua yam yog conductive nyob rau hauv nws daim ntawv plasma. Nws ua haujlwm zoo ib yam rau nitrogen.
Summing txog
Feem ntau, nitrogen tsis yog hluav taws xob conductor.
Nws yog siv los rhuav tshem qhov voltage hauv tungsten filament teeb. Hauv ib qho ntawm nws lub xeev, nws tsis tuaj yeem siv los ua hluav taws xob xa hluav taws xob tshwj tsis yog nws yog ionized. Qhov kev zam rau txoj cai yog nws daim ntawv plasma.
Qee qhov ntawm nws cov khoom yog tsim los ntawm hluav taws xob, tab sis qhov ntawd tsis tau txhais hais tias lawv tuaj yeem ua tau ib yam.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Isopropyl cawv ua hluav taws xob
- Puas yog WD40 ua hluav taws xob?
- Yuav ua li cas kuaj lub teeb fluorescent nrog lub multimeter
