Nrog rau kev nce qib ntawm kev lag luam tas mus li, cov tuam txhab petrochemical tau tsim muaj zog, uas tau txhawb nqa Tuam Tshoj txoj kev lag luam kom ua tiav, cov saw hlau muaj ntau dua, tag nrho lub zog thiab kev ua haujlwm zoo ntawm kev lag luam tau txuas ntxiv txhim kho, thiab kev tsim kho tshiab, kev sib tw, thiab muaj peev xwm tiv thaiv kev pheej hmoo tau zoo dua. Tshiab Lub pace ntawm industrialization tau nrawm heev. Tunnels thiab underground engineering tau nce siv hauv kev thauj mus los, cov chaw hauv nroog, kev txuag dej thiab kev siv hluav taws xob, kev cia khoom, kev tsim kho pob zeb thiab lwm yam.
Cov pa phem thiab cov pa phem yog hais txog cov pa roj uas muaj tshuaj lom thiab tsim kev puas tsuaj rau lub cev, xws li cov pa roj carbon monoxide, methane, thiab lwm yam. Cov pa roj carbon monoxide thiab phom sij muaj cov khoom sib txawv thiab tuaj yeem muab faib ua:
1. Irritating gas. Irritant gases hais txog cov pa roj uas ua rau lub qhov muag thiab ua pa mucosa. Lawv yog cov pa phem uas nquag ntsib hauv kev lag luam tshuaj. Muaj ntau hom roj cua uas ua rau khaus, feem ntau yog cov tshuaj chlorine, ammonia, sulfur dioxide, nitrogen oxides, hydrogen fluoride, thiab lwm yam.
2. Asphyxiating gas. Asphyxiating gases xa mus rau cov pa roj carbon monoxide uas tuaj yeem ua rau hypoxia hauv lub cev thiab tuaj yeem muab faib ua cov pa roj asphyxiating yooj yim, cov roj asphyxiating ntshav thiab cell asphyxiating gases. Xws li methane, nitrogen, ethane, carbon monoxide, ethylene, hydrogen cyanide, hydrogen sulfide, thiab lwm yam.
Irritating gases muaj nyob rau hauv ntau qhov kev tsim kho thiab cov txheej txheem tsim khoom, xws li hauv kev tsim cov ntxhia thiab lwm yam lag luam. Feem ntau ntawm cov pa roj no yog corrosive thiab tuaj yeem ua rau mob hnyav yog tias lawv nkag mus rau tib neeg lub cev los ntawm kev ua pa. Cov yam ntxwv ntawm cov tshuaj lom los ntawm cov roj gases ntawm lub cev yog qhov ua rau khaus qhov muag, ua pa mucosa thiab daim tawv nqaij mus rau qhov sib txawv. Feem ntau, kev puas tsuaj hauv zos yog qhov laj thawj tseem ceeb, tab sis nws kuj tuaj yeem ua rau muaj kev cuam tshuam hauv lub cev.
Cov pa phem thiab teeb meem electrochemical gas sensors, ua ke nrog kev txhim kho cov txheej txheem, tuaj yeem paub qhov txawv thiab saib xyuas cov pa roj carbon monoxide hauv ib puag ncig, yog li kuaj pom cov pa phem thiab cov pa phem, kev soj ntsuam raws sij hawm thiab ceeb toom ntxov ntawm cov pa ib puag ncig hauv lub qhov, uas tuaj yeem tshem tawm qhov av. kev tsim kho kev nyab xeeb kev nyab xeeb thiab muab kev tsim kho qhov av nrog kev ruaj ntseg muab kev ruaj ntseg.
Rau kev tshawb nrhiav cov pa phem thiab cov pa phem hauv ib puag ncig ntawm kev tsim kho qhov av, Huafan Technology pom zoo cov pa roj carbon monoxide thiab teeb meem hauv qab no rau kev tshawb nrhiav cov pa phem thiab cov pa phem.
1. carbon monoxide sensor
Cov pa roj carbon monoxide sensor sensor hom yog ib qho sensor raws li txoj cai electrochemical. Lub tshuab hluav taws xob hluav taws xob muaj qhov zoo ntawm qhov siab rhiab heev, kev xaiv zoo, lim daim nyias nyias, cov pa roj carbon monoxide, thiab cov txiaj ntsig zoo ntawm cov zis linearity. Nws yog tsuas yog siv hauv kev lag luam petrochemical, kev tiv thaiv ib puag ncig, thee mines, tsheb, thiab lwm yam.
2.Sulfur dioxide sensor
Cov sulfur dioxide sensor yog electrochemical sensor nrog siab rhiab heev, zoo xaiv, muaj peev xwm lim plua plav thiab dej me me, zoo low-concentration output linearity, thiab zoo stability. Nws yog tsuas yog siv nyob rau hauv sulfur dioxide gas transmitters thiab sulfur dioxide nrhiav sij hawm, roj av, thiab tshuaj industries. thiab lwm yam kev lag luam.
3.Nitrogen dioxide sensor
Nitrogen dioxide sensor yog electrochemical sensor nrog siab rhiab heev, zoo xaiv, muaj peev xwm lim plua plav thiab dej me me, zoo low-concentration output linearity, zoo stability, thiab tsis kam mus cuam tshuam los ntawm CO, CO2, thiab H2. Nws yog tsuas yog siv hauv NO2 roj. Tswb, ntes nitrogen dioxide gas concentration nyob rau hauv cov huab cua, siv nyob rau hauv roj av, tshuaj thiab lwm yam kev lag luam teb.
