Gas kho mob yog hais txog cov roj siv hauv kev kho mob.Qee qhov yog siv ncaj qha rau kev kho mob;qee qhov yog siv rau tshuaj loog;qee qhov yog siv los tsav cov cuab yeej kho mob thiab cov cuab yeej siv;qee qhov yog siv rau kev sim kho mob thiab kab mob thiab kab mob embryo.Feem ntau siv yog oxygen, nitrous oxide, carbon dioxide, argon, helium, nitrogen thiab compressed cua.
Qhov xwm thiab siv cov pa tshuaj kho mob:
1. Oxygen (Oxygen) Cov mis molecular ntawm oxygen yog O2.Nws yog ib qho muaj zog oxidizer thiab combustion enhancer.Thaum lub siab concentration oxygen ntsib cov roj, nws yuav muaj cov tshuaj tiv thaiv oxidation muaj zog, ua rau kub kub, thiab kub kub thiab tawg.Yog li ntawd, nws tau teev tseg raws li cov khoom siv phom sij rau Class B hauv "Code for Fire Protection Design of Buildings".
Txawm li cas los xij, oxygen kuj yog cov khoom siv tseem ceeb tshaj plaws los txhawb txoj sia, thiab nws yog siv los kho mob ntxiv oxygen rau cov neeg mob hypoxic.Kev nqus pa ncaj qha ntawm high-purity oxygen yog teeb meem rau tib neeg lub cev, thiab cov pa oxygen rau kev siv mus ntev feem ntau tsis tshaj 30-40%.Cov neeg mob ib txwm nqus pa oxygen los ntawm cov fwj humidifying;Cov neeg mob hnyav tau nqus pa oxygen los ntawm lub tshuab ua pa.Cov pa oxygen kuj tseem siv rau hauv cov chav ua haujlwm siab los kho cov kab mob dhia dej, ua pa lom, thiab ua kom cov tshuaj atomize.
Cov mis mos molecular ntawm nitrous oxide yog N2O.Nws yog xim tsis muaj xim, tsw ntxhiab tsw zoo, thiab tsw ntxhiab tsw ntxhiab.Tom qab ib qho me me ntawm kev nqus pa, cov leeg ntawm lub ntsej muag yuav spasm thiab kev hais lus ntawm kev luag yuav tshwm sim, yog li nws feem ntau hu ua luag nyav (laugh-gas).
Nitrous oxide yog inactive thiab tsis-corrosive ntawm chav tsev kub;Txawm li cas los xij, nws yuav oxidize aluminium, steel, tooj liab alloy thiab lwm yam hlau thaum rhuab;Nws yuav corrode polypropylene saum 60 ° C.
Nitrous oxide yuav decompose rau hauv nitrogen thiab oxygen thaum kub tshaj 650 ℃, yog li nws muaj ib tug combustion-txhawb nyhuv.Thaum kub siab, siab tshaj 15 cua yuav ua rau roj hlawv.
Laughing gas yog me ntsis soluble nyob rau hauv dej, yooj yim soluble nyob rau hauv acetone, methanol thiab ethanol, thiab yuav neutralized thiab absorbed los ntawm alkaline daws xws li high-chlorine bleaching hmoov thiab soda tshauv.
Tom qab ib qho me me ntawm nitrous oxide nqus tau pa, nws muaj cov tshuaj loog thiab cov nyhuv analgesic, tab sis ntau qhov nqus tau tuaj yeem ua rau tuag taus.Kev kho mob, kev sib xyaw ntawm nitrous oxide thiab oxygen (sib piv: 65% N2O + 35% O2) yog siv los ua tshuaj loog, thiab nws nqus tau rau tus neeg mob los ntawm txoj kev kaw lossis lub tshuab ua pa.Thaum siv tshuaj loog, siv cov pa oxygen thiab nitrous oxide flow meter los saib xyuas qhov sib xyaw ntawm ob los tiv thaiv tus neeg mob los ntawm asphyxiating.Thaum nres ua pa, tus neeg mob yuav tsum tau muab cov pa oxygen ntau dua 10 feeb los tiv thaiv hypoxia.
Siv nitrous oxide ua ib qho tshuaj loog muaj qhov zoo ntawm lub sijhawm luv luv induction, cov nyhuv analgesic zoo, rov qab sai, thiab tsis muaj teebmeem rau kev ua pa, lub siab thiab lub raum ua haujlwm.Tab sis nws muaj kev cuam tshuam me ntsis ntawm myocardium, cov leeg nqaij so tsis ua tiav, thiab kev siv tshuaj loog tsis muaj zog.Nitrous oxide ib leeg ua tshuaj loog tsuas yog tsim nyog rau kev ua haujlwm me me xws li kev tshem tawm cov hniav, kho pob txha, kev phais mob, kev phais phais, kev rho menyuam tawm, thiab tsis muaj mob.Hauv kev ua haujlwm loj, nws feem ntau siv ua ke nrog barbiturates, succinylcholine, opiates, cyclopropane, ether, thiab lwm yam los txhim kho cov nyhuv.
Laughing gas kuj tseem siv los ua cov tub yees, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv tiv thaiv khoom noj, cov khoom siv hluav taws xob, thiab lwm yam.
3. Cov pa roj carbon dioxide
Cov mis molecular ntawm carbon dioxide yog CO2, feem ntau hu ua carbon dioxide.Nws yog xim tsis muaj xim, qaub, thiab cov pa roj tsawg.Nws yog inactive nyob rau hauv chav tsev kub, soluble nyob rau hauv dej, thiab nws solubility yog 0.144g / 100g dej (25 ℃).Ntawm 20 ° C, carbon dioxide tuaj yeem dhau los ua kua tsis muaj xim los ntawm kev nias nws mus rau 5.73 × 106 Pa, uas feem ntau compressed thiab khaws cia rau hauv lub tog raj kheej.Cov pa roj carbon dioxide tuaj yeem ua rau cov dej khov qhuav los ntawm kev kub siab (5.27 × 105Pa) thiab txias (hauv qab -56.6 ℃).Cov dej khov qhuav tuaj yeem raug sublimated ncaj qha rau hauv cov pa roj ntawm 1.013 × 105 Pa (qhov siab ntawm huab cua) thiab -78.5 ° C.Thaum cov kua carbon dioxide tau evaporated sai heev nyob rau hauv lub siab txo, ib feem ntawm cov gasification tshav kub absorbed ua rau lwm yam quenched mus rau hauv ib tug snow-zoo li cov khoom, uas compresses lub snow-zoo li cov khoom rau hauv ib tug dej khov-zoo li cov khoom (cov dej khov qhuav).
Qhov kev nyab xeeb txwv ntawm cov ntsiab lus carbon dioxide hauv huab cua yog 0.5%.Yog tias nws tshaj 3%, nws yuav cuam tshuam rau lub cev.Yog tias nws siab tshaj 7%, nws yuav ua rau coma.Yog tias nws tshaj 20%, nws yuav ua rau tuag taus.
Kev kho mob, carbon dioxide yog siv los ua kom lub plab kab noj hniav thiab txoj hnyuv loj rau laparoscopy thiab fiber colonoscopy.Tsis tas li ntawd, nws kuj yog siv los cog cov kab mob (cov kab mob anaerobic) hauv chav kuaj.Cov pa roj carbon dioxide siab kuj tuaj yeem siv rau hauv cryotherapy los kho cov kab mob cataracts thiab vascular kab mob.
Cov pa roj carbon dioxide yog cov tsis-combustible, tsis-combustible, thiab hnyav dua huab cua (density 1.977g/L nyob rau hauv tus qauv tej yam kev mob, uas yog hais txog 1.5 npaug ntawm cov huab cua), uas yuav npog lub nto ntawm cov khoom thiab cais cov huab cua, yog li nws feem ntau yog siv hluav taws tua hluav taws, siv rau cov pa roj carbon dioxide shielded vuam (siv los cais cov pa oxygen), thiab lwm yam. Cov dej khov qhuav tuaj yeem siv ua cov tub yees, sib tov kom tsis muaj menyuam, thiab siv rau cov dej nag.
4. Argon
Cov mis mos molecular ntawm argon yog Ar.Nws yog xim tsis muaj xim, tsis muaj ntxhiab thiab tsis muaj tshuaj lom inert gas.Nws yog non-flammable, non-combustible, thiab tsis chemically react nrog lwm yam tshuaj, yog li nws yuav siv tau los tiv thaiv hlau los ntawm oxidation.
Cov roj argon yog ionized rau hauv argon roj ions nyob rau hauv qhov kev txiav txim ntawm lub siab zaus thiab siab.Qhov no argon roj ion muaj cov conductivity zoo heev thiab tuaj yeem xa mus tsis tu ncua.Cov roj argon nws tus kheej tuaj yeem txo qhov kub ntawm lub qhov txhab thaum lub sijhawm ua haujlwm, thiab txo cov oxidation thiab carbonization (pas luam yeeb, eschar) ntawm cov ntaub so ntswg puas.Yog li ntawd, nws yog feem ntau siv rau kev siv ntau zaus hauv kev kho mob.
Cov cuab yeej phais xws li argon riam.
Argon kuj tseem siv rau hauv argon shielded vuam, fluorescent teeb, integrated circuit manufacturing, thiab lwm yam.
