Helium (zeeg)

Technical Parameters

Helium yog ib qho tsis tshua muaj roj, lub teeb heev, tsis muaj xim thiab tsw ntxhiab inert gas. Nws yog chemically inactive, thiab nws yog ib qho nyuaj rau react nrog lwm yam tshuaj nyob rau hauv ib txwm tej yam kev mob. Nws muaj cov tshuaj lom neeg ruaj khov thiab muaj xim daj tsaus nti thaum ua haujlwm qis-voltage paug. Helium tuaj yeem siv los ua tus neeg sawv cev thiab supercharger rau lub foob pob hluav taws ua kua roj, thiab siv ntau hauv cov foob pob hluav taws, lub dav hlau thiab lub dav hlau supersonic; raws li ib tug shielding roj thaum smelting thiab welding, nws yog siv nyob rau hauv shipbuilding, aircraft, spacecraft, foob pob ua ntxaij, thiab kev tsim riam phom yog ib qho tseem ceeb heev; helium muaj permeability zoo heev thiab yog siv los ua kom txias nuclear reactors, thiab txhawm rau txheeb xyuas cov xau hauv cov foob pob hluav taws thiab nuclear reactors ' pipelines thiab cov khoom siv hluav taws xob thiab hluav taws xob; Helium muaj tsawg txhiab qhov ntom ntom thiab yuag ntom, thiab nws tsis yog nplaim thiab tuaj yeem siv los ua qhov muag teeb thiab neon hlab ntsha. Nws kuj yog ib qho zoo tagnrho roj rau balloons thiab airships; kua helium tuaj yeem tau txais qhov ntsuas kub tsawg ze rau qhov kub thiab txias (-273 ° C) thiab siv los ua cov khoom siv superconducting; helium yog ib hom roj inert, lub solubility nyob rau hauv cov ntshav yog qis dua nitrogen, yog li nws cov tshuaj loog yog qis dua li nitrogen. Yog li ntawd, helium thiab oxygen feem ntau sib xyaw ua pa ua pa rau cov neeg dhia dej. Helium yuav tsum tau muab khaws cia rau hauv qhov chaw zoo, muaj kev nyab xeeb thiab tsis muaj huab cua, thiab qhov kub cia yuav tsum tsis txhob siab tshaj 52 ° C. Yuav tsum tsis txhob muaj cov khoom siv hluav taws kub hauv qhov chaw khaws cia thiab kom deb ntawm qhov chaw nkag mus thiab tawm thiab tawm thaum muaj xwm txheej ceev, thiab tsis muaj ntsev lossis lwm yam khoom siv corrosive. Rau lub tog raj kheej tsis siv roj, lub hau valve thiab cov khoom tso tawm valve yuav tsum raug kaw kom zoo, thiab lub tog raj kheej khoob yuav tsum tau muab cais tawm ntawm tag nrho lub tog raj kheej. Tsis txhob cia ntau dhau thiab khaws cia ntev, thiab khaws cov ntaub ntawv khaws cia zoo.

Daim ntawv thov:

1.Cryogenic Cooling Siv:

Helium roj dav siv hauv tsheb ciav hlau maglev thiab kev kho mob Nuclear magnetic resonance (NMR) cov khoom siv duab.

2. Kev siv Balloon:

Inflat rau ballon rau hnub yug tog lossis kev ua koob tsheej lossis inflat rau airship.

3.Kuaj Analyse:

Helium gas dav siv hauv vaccum to detection xws li helium mass spectrometer leak detector.

4.Shielding Gas:

Helium feem ntau siv los ua magnesium, zirconium thiab txhuas, titanium thiab lwm yam hlau vuam tiv thaiv roj.

Pob Loj:

Qhov zoo:

1. Peb lub Hoobkas tsim Helium los ntawm cov khoom zoo raw khoom, nrog rau tus nqi pheej yig.
2. Lub Helium yog tsim tom qab ntau lub sij hawm cov txheej txheem ntawm purification thiab rectification nyob rau hauv peb lub Hoobkas.Qhov kev tswj xyuas hauv internet tau lees paub cov roj purity txhua theem.Cov khoom tiav yuav tsum ua raws li tus qauv.
3. Thaum lub sij hawm txhaws, lub tog raj kheej yuav tsum tau ua ntej qhuav rau ib lub sij hawm ntev (tsawg kawg 16 teev), ces peb nqus lub tog raj kheej, thaum kawg peb tshem nws nrog cov roj qub.Tag nrho cov txheej txheem no xyuas kom meej tias cov roj ntshiab hauv lub tog raj kheej.
4. Peb muaj nyob rau hauv Gas teb rau ntau xyoo, nplua nuj kev nyob rau hauv ntau lawm thiab export cia peb yeej cov neeg muas zaub' ntseeg, lawv txaus siab rau peb cov kev pabcuam thiab muab lus zoo rau peb.
