Ua tib zoo saib xyuas kev siv ammonia gas detector
Cov yam ntxwv ntawm cov pa roj ammonia: cov roj ammonia yog cov roj tsis muaj xim, muaj tshuaj lom, muaj kev phom sij ntawm 2.2. Nws muaj ib tug pungent tsw. cov tub yees siv. Cov mis mos molecular NH3. Molecular hnyav 17.03. Tus txheeb ze ntom ntom yog 0.7714g/l. Melting point -77.7 degree . Kub taw tes -33.35 degree . Lub qhov hluav taws xob tshwm sim yog 651.11 degree. Vapor ceev 0.6. Lub vapor siab yog 1013.08kPa (25.7 degree). Qhov kev txwv tawg ntawm vapor thiab huab cua sib xyaw yog 16-25 feem pua (qhov feem ntau cov nplaim taws yog 17 feem pua).
Raws li lub teb chaws tus qauv "Occupational Exposure Limits of Hazardous Factors in the Workplace GBZ2-2002", qhov siab tshaj plaws tso cai ntawm ammonia nyob rau hauv lub rooj cob qhia yog 30mg / M3, uas yog hais txog 39.5ppm. Hauv kev sim tiag tiag, cov txiaj ntsig hauv qab no feem ntau raug xa mus rau:
Qhov nruab nrab qhov nruab nrab (TLV-TWA): 25 (feem ntau teem raws li lub tswb ceeb thawj)
Instantaneous threshold (TLV-STEL): 35 (feem ntau teem ua lub tswb thib ob)
Dangerous concentration (IDLH): 100ppm-500ppm
