什么是粉塵？粉塵：可燃性粉塵在極限范圍內(nèi)，遇到熱源（明火或高溫），火焰瞬間傳播于整個(gè)混合粉塵空間，化學(xué)反應(yīng)速度極快，同時(shí)釋放大量的熱，形成很高的溫度和很大的壓力，系統(tǒng)的能量轉(zhuǎn)化為機(jī)械能以及光和熱的輻射，具有很強(qiáng)的破壞力。粉塵多在伴有鋁粉、鋅粉、鋁材加工研磨粉、各種塑料粉末、有機(jī)合成藥品的中間體、小麥粉、糖、木屑、染料、膠木灰、奶粉、茶葉粉末、粉塵粉末、煤塵、植物纖維塵等產(chǎn)生的生產(chǎn)加工場(chǎng)所。粉塵性試驗(yàn)?zāi)睦锟梢宰觯空椅⒆V！黑龍江粉塵測(cè)試檢測(cè)服務(wù)價(jià)格</p><p
