qauv ntawm kev ruaj ntseg

Khoom. Poov tshuaj nitrate - yog ib tug muaj zog oxidant. Nws reacts nrog txo thiab combustible cov ntaub ntawv. Nws ceev yog 2,109 g / cm³, boiling kub - 400 ° C, 334 ° C - lub melting point. Kev poov tshuaj nitrate yog sufficiently tshuaj lom thiab nws siab tshaj plaws permissible concentration nyob rau hauv cov huab cua nyob rau hauv cov chav yuav tsum tsis txhob ntau tshaj 5 mg / m. Nqus tau pa poov tshuaj nitrate vapor rau lub qhov ntswg mucosa thiab lub rwj peev xwm yuav tsim o, thiab los ntawm heev hu rau ntawm daim tawv nqaij yuav tshwm sim thickenings xib teg thiab qab xib taws.
