Dab tsi gases tuaj yeem kuaj xyuas VOC?
Suav lub npe ntawm VOC yog: volatile organic tebchaw. Muaj ntau pua hom organic volatile gases. Feem ntau hauv lub neej muaj xws li formaldehyde, cawv, toluene, thiab xylene, uas yog tag nrho cov organic volatiles. Txhawm rau txheeb xyuas cov organic volatiles, koj yuav tsum siv lub ntsuas VOC. VOC detectors yog siv los ntsuas cov pa roj carbon monoxide lom nyob rau hauv ib puag ncig txaus ntshai. Lawv feem ntau yog siv rau hauv kev luam ntawv, rooj tog tsim, shoemaking, petrochemicals, roj refining thiab lwm yam lag luam. Yog li dab tsi gases tuaj yeem ntes VOC detectors?
Lub VOC detector siv lub photoionization gas sensor (PID) los kuaj cov organic tebchaw (VOC). Lub photoionization gas sensor (PID) feem ntau yog siv rau kev tshawb nrhiav cov organic tebchaw (VOC). Cov volatiles no muaj xws li:
Aromatics: benzene, xylene, naphthalene, thiab lwm yam.;
Saturated hydrocarbons thiab unsaturated hydrocarbons: octane, ethylene, cyclohexane, thiab lwm yam.;
Ketones, aldehydes, ethers: acetone, propionaldehyde, propyl methyl ether, thiab lwm yam;
Halogenated hydrocarbons, sulfur hydrocarbons, cawv, esters, hydrazines, thiab lwm yam.
Tsis tas li ntawd, cov tshuaj uas tsis muaj tshuaj lom muaj xws li arsenic thiab ammonia.
Cov pa roj tau hais los saum toj no uas VOC ntes tau tuaj yeem sib koom ntawm no. VOC detectors muaj qhov zoo ntawm cov teeb liab ruaj khov, siab precision thiab zoo repeatability. Lawv tau siv dav hauv cov roj refining thiab petrochemicals, tshuaj lom neeg ntau lawm, hluavtaws fiber ntau, thiab txheej txheej. , luam ntawv rooj tog, khoom siv hluav taws xob thiab textile printing thiab dyeing thiab lwm yam lag luam.
