style="text-indent:25px">防毒面具的密閉性取決于面罩各個(gè)接口的密合性，比如視線窗口、過(guò)濾盒以及頸部貼合部位等，所以在選擇防毒面具時(shí)，要注意一下幾點(diǎn)：面具的大小，盡量選用面具型號(hào)尺寸稍大于自己的頭型；確認(rèn)視窗位置是否與眼部平行、嘴部的呼吸位置與面罩內(nèi)部是否有干涉；較重要的一項(xiàng)，家用防毒面具一般有使用有效防護(hù)時(shí)間，通常按救援時(shí)間，較佳的防護(hù)時(shí)間選用40分鐘左右規(guī)格。火災(zāi)一旦發(fā)生，要一時(shí)間佩戴好防毒面具，平穩(wěn)不要驚慌，因?yàn)闈鉄熋芏群苄腋≡诳罩?，所以一定要彎腰或者匍匐前行，避免高溫濃煙灼傷呼?**等傷害。只有掌握好防毒面具的使用，才能在危險(xiǎn)發(fā)生時(shí)做到更有效的逃生。深圳防毒面具供應(yīng)廠家防毒面具按防護(hù)原理，可分為過(guò)濾式防毒面具和隔絕式防毒面具。</p><div

style="text-indent:25px">防毒面具中的浸漬活性炭通過(guò)如下3種作用來(lái)達(dá)到防毒目的物理吸附作用。所謂吸附，是指流體分子在固體表面增稠或凝聚的現(xiàn)象。物理吸附是由吸附質(zhì)與吸附劑分子間的力相互吸引發(fā)生的，被吸附分子保持著原來(lái)的化學(xué)性質(zhì)，吸附熱較低，無(wú)選擇性，吸附和脫附速度較快，例如，活性炭對(duì)沙林、芥子氣、氯等毒劑蒸氣就是物理吸附作用?；瘜W(xué)吸附作用。化學(xué)吸附是由吸附質(zhì)與吸附劑分子之間以類(lèi)似化學(xué)鏈的力相吸發(fā)生的，吸附質(zhì)與吸附劑形成表面化合物，吸附熱較高，有選擇性，通常不可逆。浸漬炭借助于添加金屬氧化物來(lái)提高對(duì)難吸附毒劑的防毒能力。在浸漬炭吸附光氣時(shí)炭上的水分能與之發(fā)生水解反應(yīng)。所以，當(dāng)濾毒罐受潮后，對(duì)光氣的防護(hù)能力會(huì)有所提高。由于化學(xué)吸著作用是在炭上發(fā)生化學(xué)變化，所以過(guò)濾罐吸收**氫之類(lèi)的毒劑失效以后，是不能用普通辦法使之再生的。而借助物理吸附作用進(jìn)行防護(hù)時(shí)，過(guò)濾罐失效以后還可以再生。</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，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，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(kāi)纖維，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)。山東防毒面具廠</p><p
