class="box"><p><p style="text-indent:25px">防毒面具過(guò)濾層如何過(guò)濾氣溶膠目前常用玻璃纖維過(guò)濾層，它由許多層縱橫交錯(cuò)的纖維網(wǎng)格組成，廣東防毒面具制作，氣溶膠微粒通過(guò)時(shí)，總會(huì)接觸到纖維上而被阻留。發(fā)生這種接觸的效應(yīng)有截留效應(yīng)、慣性效應(yīng)、擴(kuò)散效應(yīng)和靜電效應(yīng)等四種，其中起主要作用的是**種效應(yīng)。截留效應(yīng)當(dāng)空氣流通過(guò)垂直于氣流方向的纖維時(shí)，氣流被分散和壓縮試圖繞過(guò)纖維，在通過(guò)后再重新匯合。如果空氣流中的粒子中心在小于粒子半徑的距離通過(guò)纖維表面，會(huì)和纖維表面碰撞被捕獲。粒子尺寸增大，廣東防毒面具制作，截留捕獲的可能性也增大。沉降效應(yīng)只有大于2微米的粒子可以通過(guò)沉降捕獲，它取決于重力對(duì)氣流中粒子的吸引力，因此通過(guò)濾煙層的流速必須很低。慣性效應(yīng)當(dāng)具有足夠慣性的粒子不能充分改變方向而避開纖維，廣東防毒面具制作，就會(huì)碰撞到纖維表面上被捕獲。擴(kuò)散效應(yīng)較小粒子的運(yùn)動(dòng)受到和它相碰撞的空氣分子的影響，然后在空氣流做無(wú)規(guī)則的運(yùn)動(dòng)，通過(guò)時(shí)和纖維發(fā)生碰撞被捕獲。取決于粒子的尺寸和空氣溫度。靜電效應(yīng)在靜電效應(yīng)中，目標(biāo)粒子具有自然的電荷，使過(guò)濾纖維帶有相反的電荷。因此粒子被吸引到纖維上。靜電效應(yīng)有助于其它捕獲效應(yīng)，特別是截留和擴(kuò)散效應(yīng)。防毒面具的防毒時(shí)間同選定濾毒罐的性能。廣東防毒面具制作</p><div
