Nrog rau kev nce qib thiab kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no, kev siv tshuaj kho mob tseem niaj hnub hloov zuj zus, thiab tshuaj yog qhov tseem ceeb rau peb lub neej. Txawm li cas los xij, cov txheej txheem kev tsim tshuaj muaj cov tshuaj synthesis, bio fermentation, thiab extraction, uas yuav tsum tau siv ntau yam tshuaj lom neeg, nrog rau cov tshuaj lom neeg. Txhawm rau kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm, kev siv cov khoom siv roj hauv cov chaw tsim tshuaj yog qhov tseem ceeb, thiab tsim kom muaj kev nyab xeeb ntawm cov pa roj thiab kev tswj xyuas kev nyab xeeb yog qhov tseem ceeb.
Cov txheej txheem kev tsim tshuaj siv aliphatic thiab aromatic hydrocarbons, cawv ntau, ketones, thiab esters. Cov pa roj muaj xws li methane, ethane, ethanol, ethyl acetate, benzene, toluene, thiab xylene. Cov pa roj no tau siv ntau thiab muaj kev phom sij heev, nrog rau ntau yam khoom siv hluav taws xob thiab tawg.
Cov khoom fermentation lom tau muaj kev loj hlob sai nyob rau hauv lub xyoo pua 21st, tab sis fermentation metabolites raug tso tawm hauv cov pa pa, nrog rau cov ntxhiab tsw phem. Qhov concentration ntawm cov khoom xyaw tshuaj los yog derivatives hauv huab cua tseem nce ntxiv, uas ua rau muaj kev hem thawj rau tib neeg thiab ib puag ncig.
Cov pa phem thiab phem- cov pa roj tsw qab xws li ammonia thiab hydrogen sulfide kuj raug tsim thaum lub sijhawm ua tshuaj.
Lub "GB 37823-2019 Pharmaceutical Industry Air Pollutant Emission Standard" qhia txog huab cua pa phem emission txwv rau kev lag luam kws tshuaj, feem ntau saib xyuas cov teeb meem, NMHC, TVOC, benzene series, phosgene, hydrogen cyanide, benzene, formaldehyde, hydrogen chlorideine, chloride thiab hydrogen chloride.
Nyob rau hauv luv luv, ntau yam gases koom nyob rau hauv kev tsim tshuaj thiab kev ua, txawm nyob rau hauv kev sim, ntau lawm, lub neej txhua hnub, kev tswj, los yog kom tsis muaj menyuam. Qee qhov ntawm cov roj no muaj cov khoom tawg thiab tawg. Thaum cov dej xau tawm mus txog qhov kev txwv qis qis, lawv muaj feem ntau yuav tawg thiab tawg thaum raug hluav taws kub thiab qhov chaw kub. Qee qhov teeb meem rau tib neeg lub cev. Thaum nqus tau, lawv tuaj yeem ua rau khaus ntawm daim tawv nqaij thiab cov mucous membranes, lossis txawm tias lub cev puas tsuaj lossis tuag taus. Kev siv cov cuab yeej ntsuas roj hauv cov chaw tsim tshuaj tuaj yeem muab qee theem ntawm kev ceeb toom ntxov ntawm cov pa xau thiab txo qhov tshwm sim ntawm cov xwm txheej txaus ntshai.
Huafan Technology's Gas Detectors tuaj yeem ntes tau ntau yam roj av, tso cai rau koj xaiv cov pa roj uas tsim nyog tshaj plaws raws li hom roj, ntau yam, thiab qhov tseeb. Cov cuab yeej muaj xws li portable gas detectors, pump-hom gas detectors, fixed gas detectors, and gas alarm control panels. Cov cuab yeej muaj kev ua haujlwm siab -kev ua tau zoo, siab precision, thiab cov lus teb ceev ceev, ua rau nws tsim nyog siv rau hauv qhov chaw ua haujlwm nyuaj. Cov neeg siv khoom tuaj yeem xaiv lub ntsuas roj kom tsim nyog raws li qhov chaw sim.
