Dab tsi yog nitrous oxide

 

Nitrous oxide, ib yam khoom tsis muaj zog nrog cov tshuaj formula N2O, yog ib qho tshuaj lom neeg uas zoo li tsis muaj xim thiab qab zib. Nws yog ib qho oxidant uas tuaj yeem txhawb kev sib tsoo hauv qee yam mob, tab sis ruaj khov ntawm chav tsev kub, muaj cov tshuaj loog me me, thiab tuaj yeem ua rau luag. Nws cov tshuaj loog tau pom los ntawm British chemist Humphrey David hauv 1799.

Kev siv cov nitrous oxide

 

Automotive kev lag luam

Kev pab cuam combustion: Hloov tsheb siv lub tshuab pa oxygen acceleration pub nitrous oxide rau hauv lub cav, uas decomposes rau hauv nitrogen thiab oxygen thaum rhuab, ua rau lub cav combustion tus nqi thiab ceev. Oxygen muaj cov nyhuv combustion, ua kom cov roj combustion nrawm.

 

National Defense Technology Kev Lag Luam

Rocket oxidizer: Nitrous oxide tuaj yeem siv los ua lub foob pob hluav taws oxidizer. Qhov zoo ntawm qhov no tshaj lwm cov oxidants yog tias nws tsis muaj tshuaj lom, ruaj khov ntawm chav tsev kub, yooj yim khaws cia, thiab muaj kev nyab xeeb rau lub davhlau. Qhov txiaj ntsig thib ob yog tias nws tuaj yeem yooj yim decompose rau hauv cov pa ua pa.

 

Tshuaj kho mob

Tshuaj loog: Nitrous oxide, nitrous oxide, feem ntau siv ua ke nrog halothane, methoxyflurane, ether, los yog intravenous general anesthesia vim tsis zoo cov tshuaj loog. Nws yog tam sim no underused. N2O yog siv rau tshuaj loog, tsis muaj kev ua xua rau lub ntsws, thiab tsis muaj kev puas tsuaj rau lub cev tseem ceeb xws li lub plawv, lub ntsws, lub siab, thiab lub raum. Tsis muaj kev hloov pauv lom lossis kev puas tsuaj hauv lub cev, feem ntau ntawm cov tshuaj tseem raug tshem tawm ntawm lub cev los ntawm exhalation, tsuas yog ib qho me me evaporated ntawm daim tawv nqaij thiab tsis muaj kev cuam tshuam. Kev nqus tau rau hauv lub cev tsuas yog siv sijhawm 30 mus rau 40 vib nas this los tsim cov teebmeem analgesic. Cov nyhuv analgesic muaj zog tab sis cov nyhuv tshuaj loog tsis muaj zog, thiab tus neeg mob nyob hauv lub xeev tsis nco qab (tsis yog lub xeev tshuaj loog), zam cov teeb meem ntawm cov tshuaj loog thiab rov zoo sai tom qab kev phais.

 

Kev lag luam zaub mov

Khoom noj khoom haus pab: Siv nyob rau hauv kev lag luam khoom noj khoom haus raws li foaming agents thiab sealants, lawv yog cov tseem ceeb Cheebtsam ntawm cream chargers thiab ua lub luag hauj lwm tseem ceeb nyob rau hauv ua kom qab ntxiag whipped cream. Cov khoom ntawm nitrous oxide txhim khu kev ntxhib los mos, ruaj khov, thiab saj ntawm whipped cream, ua rau nws yuav tsum muaj rau cov ncuav pastries lossis cov kws ua zaub mov hauv tsev.

Kev pheej hmoo ntawm Nitrous Oxide

 

Kev siv cov nitrous oxide kuj muaj qee qhov kev pheej hmoo thiab muaj feem cuam tshuam. Ib qho kev pheej hmoo tseem ceeb ntawm kev siv nitrous oxide yog hypoxia. Kev nqus pa ntawm nitrous oxide thiab huab cua, thaum cov pa oxygen concentration tsawg heev, nitrous oxide tuaj yeem hloov cov pa oxygen hauv lub ntsws thiab cov ntshav, ua rau hypoxia thiab muaj feem cuam tshuam rau lub neej xws li kev puas hlwb, qaug dab peg, thiab tuag taus. Kev haus luam yeeb ntev ntev tuaj yeem ua rau kub siab, syncope, thiab txawm tias lub plawv nres. Tsis tas li ntawd, qhov ntev ntev ntawm cov roj no tuaj yeem ua rau cov ntshav tsis txaus thiab ua rau lub hauv nruab nrab lub paj hlwb puas.

Ntxiv nrog rau kev pheej hmoo ntawm kev noj qab haus huv, kev tsim txom ntawm nitrous oxide kuj tuaj yeem ua rau muaj xwm txheej thiab lwm yam tsis zoo. Hom roj no feem ntau yog siv rau kev lom zem, thiab tib neeg yuav nqus tau cov pa roj ntau hauv lub sijhawm luv luv, ua rau muaj kev txiav txim siab tsis zoo thiab kev sib koom ua ke ntawm lub cev muaj zog, ua rau muaj xwm txheej thiab raug mob. Kev siv tsis zoo ntawm nitrous oxide kuj tuaj yeem ua rau kub hnyiab thiab frostbite, vim tias cov roj tau khaws cia rau hauv siab thiab tso tawm, ua rau kub poob sai.
