Tsis tshua muaj roj

Tsis tshua muaj gases, tseem hu ua noble gases thiab noble gases, yog ib pawg ntawm cov ntsiab lus uas muaj nyob rau hauv tsawg concentrations nyob rau hauv cov huab cua thiab muaj kev ruaj ntseg heev.Tsis tshua muaj gases nyob rau hauv Pawg Zero ntawm Lub Sij Hawm Lub Sijhawm thiab suav nrog helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), uas nyuam qhuav tau ntxiv rau. Periodic Table tsev neeg ntawm cov ntsiab lus.
Tsis tshua muaj gases suav txog li 0.94% ntawm cov huab cua, feem ntau yog argon, thiab tsis muaj xim, tsis muaj ntxhiab, tsis qab, me ntsis soluble hauv dej, nyob rau hauv daim ntawv ntawm monatomic gas molecules muaj nyob rau hauv cov huab cua, uas helium, neon, argon. , krypton, vim tias tsis muaj xov tooj cua thiab nyuaj heev rau kev hnov ​​​​mob ntawm chav tsev kub thiab siab, tuaj yeem siv los ua cov roj tiv thaiv hauv metallurgy, semiconductors thiab lwm yam.
Nrog rau kev zam ntawm germanium, uas tsuas yog tuaj yeem tau txais cov khoom siv hluav taws xob, yog cov xov tooj cua heev thiab tsis ruaj khov, lwm cov pa roj tsawg tau pom cov ntawv tshwj xeeb hauv ntau qhov chaw uas tsis yog cov roj tiv thaiv.Atomic huab hwm coj tsuas yog siab dua hydrogen, qhov xwm txheej ntawm helium ruaj khov tuaj yeem hloov tau hydrogen raws li lub zais pa ruaj ntseg ntim roj, tab sis kuj tuaj yeem hloov nitrogen raws li kev sib sib zog nqus dhia nrog compressed roj lub tog raj kheej filling gas, kom tsis txhob qaug zog nitrogen cov tshuaj tiv thaiv thiab oxygen. toxicity;argon los ntawm high-zog cosmic rays yuav ionized tom qab irradiation, yuav tsum tau teem nyob rau hauv dag satellites nrog argon counters los txiav txim qhov chaw ntawm lub cosmic radiation txoj siv thiab qhov siv ntawm lub cosmic chaw;xenon tuaj yeem yaj hauv cellular lipids, ua rau cellular anesthesia.Xenon tuaj yeem yaj hauv cov lipids ntawm cov hlwb, ua rau tuag tes tuag taw thiab o ntawm cov hlwb, thiab ua rau cov paj hlwb tsis ua haujlwm ib ntus.Nws tuaj yeem tov nrog oxygen ntawm qhov sib piv ntawm 4: 1 raws li cov tshuaj loog tsis muaj kev phiv;radon, raws li cov roj hluav taws xob nkaus xwb hauv qhov xwm txheej, tuaj yeem cuam tshuam los ntawm kev lwj ntawm thorium hauv cov khoom siv hauv tsev tsis zoo, thiab ua rau mob qog noj ntshav, tab sis nws tuaj yeem sib xyaw thiab kaw nrog cov hmoov beryllium thiab siv los ua cov khoom siv neutron hauv cov chaw sim.
Tsis tshua muaj gases emit lub teeb ci thiab vibrant thaum muaj zog.Los ntawm kev sau cov teeb nrog kev sib xyaw ntawm ntau hom thiab qhov sib npaug ntawm helium, neon, argon, krypton, mercury vapor, thiab halogen compounds, ntau hom teeb pom kev zoo xws li neon, fluorescent, fluorescent, thiab tsheb headlamps tuaj yeem tau txais ntau yam. xim.
Lub melting point thiab boiling point ntawm tsawg gases yog tsawg heev, thiab cov tsoos txoj kev yog liquefy huab cua los ntawm lub zog-siv pressurization thiab txias thiab ces fractionate nws kom tau neon, argon, krypton thiab xenon;helium feem ntau yog muab rho tawm los ntawm cov pa roj;thiab radon feem ntau yog sib cais los ntawm radium tebchaw tom qab radioactive decay.
Shanghai Jiuzhou zeolite molecular sieve, tsis tshua muaj roj sib cais nyhuv yog qhov zoo, siab purity, ceev ceev, tsis muaj zog noj, raws li kev sib txawv ua hauj lwm tej yam kev mob los muab koj nrog kev customized kev pab cuam.Peb tos ntsoov yuav koom tes nrog koj los tsim lub neej yav tom ntej zoo dua.
