Dab tsi yog Daim Ntawv Thov Kev Ua Haujlwm ntawm Kev Lag Luam Portable Gas Detectors?
Tej zaum yuav muaj qee cov pa phem thiab cov pa phem hauv huab cua, thiab txhawm rau ntsuas lawv cov concentration, cov khoom siv roj tuaj yeem siv los kuaj xyuas. Vim muaj ntau hom twj paj nruag, lawv daim ntawv thov teb kuj yuav txawv. Hauv qab no, peb yuav ua kom paub cov teb uas portable gas detectors tuaj yeem siv rau hauv.
Daim ntawv thov teb ntawm portable gas detectors
1. Roj thiab roj:
Portable gas detectors tuaj yeem siv rau hauv thaj chaw xws li roj thiab roj, vim tias cov pa xau tuaj yeem tshwm sim thaum lub sijhawm rho tawm, kev thauj mus los, kev cia, thiab cov txheej txheem smelting ntawm cov roj lossis roj. Yog li nws tuaj yeem siv los ua cov cuab yeej ceeb toom.
2. Chemical site:
Nyob rau hauv thaj chaw ntawm cov nroj tsuag tshuaj, ib tug loj npaum li cas ntawm cov tshuaj lom gases feem ntau yog generated, yog li ntawd yuav tsum tau siv cov cuab yeej siv tshuaj nyob rau hauv tshuaj. Lawv feem ntau pom cov pa roj carbon monoxide dav dav thiab ntau yam pa phem, xws li hydrogen sulfide, ammonia, thiab lwm yam.
3. Tsev Kho Mob:
Cov roj pov tseg kho mob tsim tawm hauv cov chaw kuaj mob feem ntau muaj ntau cov pa phem. Txhawm rau kom cov neeg ua haujlwm muaj kev nyab xeeb, cov khoom siv hluav taws xob tuaj yeem siv tau.
4. Underground tunnels thiab chaw nres tsheb:
Hauv qee qhov chaw kaw thiab chaw nres tsheb, nws yog ib qho tsim nyog los saib xyuas cov pa pa tawm hauv huab cua. Thaum cov roj concentration ua rau muaj kev hem thawj rau tib neeg kev nyab xeeb, kev ntsuas raws sijhawm tuaj yeem ua.
5. Kev tsim khoom semiconductor:
Nyob rau hauv cov txheej txheem ntawm semiconductor ntau lawm, phosphorus, arsenic, boron, gallium, thiab lwm yam additives feem ntau yog siv, thiab hydrogen gas kuj siv raws li ib tug reactant kom txo tau ib co ntawm lawv, uas yuav ua rau muaj ntau flammable thiab lom gases nyob rau hauv lub tam sim no ib puag ncig. Nyob rau hauv rooj plaub no, portable gas detectors yog xav tau rau kev kuaj xyuas.
6. Chaw nres tsheb fais fab:
Feem ntau, thee lossis roj yog siv los ua cov khoom siv raw hauv kev lag luam cog hluav taws xob, yog li lub luag haujlwm ntawm cov khoom siv hluav taws xob portable hauv cov ntawv thov cog hluav taws xob feem ntau yog txhawm rau txheeb xyuas cov roj hluav taws xob xws li cov nkev, hydrogen, thiab cov pa phem xws li CO thiab SO.
