style="text-indent:25px">防毒面具過濾層如何過濾氣溶膠目前常用玻璃纖維過濾層，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)空氣流通過垂直于氣流方向的纖維時(shí)，氣流被分散和壓縮試圖繞過纖維，在通過后再重新匯合。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沉降捕獲，它取決于重力對(duì)氣流中粒子的吸引力，四川火災(zāi)防毒面具，因此通過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，就會(huì)碰撞到纖維表面上被捕獲，四川火災(zāi)防毒面具。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，四川火災(zāi)防毒面具，然后在空氣流做無規(guī)則的運(yùn)動(dòng)，通過時(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)。防毒面具過濾層是專門用來過濾有害氣溶膠的。四川火災(zāi)防毒面具</p><div

style="text-indent:25px">除了正確佩戴防毒面具，關(guān)于噴漆防護(hù)方案也是你必須要了解的。面具品牌不同種類噴漆防毒面具，其防護(hù)效果不同，市面上常見的噴漆防毒面具品牌有3M防毒面具、霍尼韋爾(巴固)、代爾塔等等。防毒面具價(jià)格與面罩品牌、面罩材質(zhì)、面罩類型及佩戴舒適性相關(guān)。油漆中的有毒有害物均屬于有機(jī)氣體及顆粒物，所以噴漆防毒面具濾毒盒的選擇一定要具備防有機(jī)蒸氣的特性。面具類型噴漆防毒面具類型基本分為兩種：自吸過濾式防毒面具和隔絕式防毒面具。自吸過濾式噴漆防毒面具大多用于汽車4S店、五金店等作業(yè)場合空曠通風(fēng)、氧氣濃度高的環(huán)境中；而隔絕式噴漆防毒面具，大多為長管呼吸器（或空氣呼吸器），用于缺氧、漆霧濃度高及密閉空間，如密閉的油罐、鍋爐等。河南防毒面具品牌防毒面具的材質(zhì)已由普通橡膠,改為硅橡膠。</p><div

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?；馂?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。</p><p style="text-indent:25px">防毒面具主要依靠濾毒罐防毒，其中的裝填物由吸附劑層和過濾層構(gòu)成，其中吸附劑層濾除有毒氣體和蒸汽，過濾層則過濾有害氣溶膠。因?yàn)閷?duì)蒸汽狀毒劑的吸著和對(duì)有害氣溶膠的過濾過程不同，防毒原理也不同。吸附劑層的防毒原理吸附劑層中，用的是載有催化劑的活性炭，即浸漬活性炭，這種經(jīng)過活化處理的無定形炭是多孔吸附劑，主要成分是碳，含量約為80%～98%，另有少量灰分。活性炭的孔隙一般分為微孔、過渡孔、大孔3類，有時(shí)過渡孔也稱為中孔。微孔較小，有效半徑0.5～1納米，上限為1.5納米，所占的全部容積約為0.15～0.5厘米3/克。由于這類孔小而數(shù)量多，所形成的比表面積約占活性炭比表面積總數(shù)的90%以上，活性炭對(duì)毒劑蒸氣的吸附主要靠它。因此微孔的多少和分布在很大程度上決定某種特定活性炭的吸附能力。在吸附過程中，這三種孔隙互相連通，微孔在內(nèi)，過渡孔和大孔在吸附過程中起通道作用。過渡孔和大孔表面載有銅、銀、鉻或鉬、鋅等金屬氧化物，它們的加入數(shù)量對(duì)防毒性能影響較大。防毒面具，依照其防護(hù)原理來區(qū)別，可分為過濾式防毒面具和阻隔式防毒面具。</p><div

style="text-indent:25px">防毒面具可以有效的過濾掉噴漆車間中的甲醛等有毒氣體，那么噴油漆用什么防毒面具好呢？選擇一款較好的防毒面具，首先是要看這款防毒面具的材質(zhì)，特別是防毒面具的中樞—口鼻罩的材質(zhì)，目前而言，口鼻罩材質(zhì)有醫(yī)用橡膠和醫(yī)用硅膠，相比來說，橡膠材質(zhì)無論從柔軟性、舒適性而言都要遜于硅膠，而硅膠又分為醫(yī)用硅膠和食品級(jí)硅膠，對(duì)化學(xué)材料過敏的人員需要注意，醫(yī)用硅膠很有可能導(dǎo)致敏感人群的過敏癥狀，而食品級(jí)硅膠過敏的概率則要小很多。選擇防毒面具還要注意濾毒罐是否搭配，噴漆車間一般都是有機(jī)毒氣較多，這樣要選擇A型3號(hào)綜合有機(jī)氣體**濾毒罐，起到較好的防護(hù)效果。在使用防毒面具之前，應(yīng)該對(duì)其進(jìn)行認(rèn)真的檢查。江西醫(yī)用防毒面具</p><p
