style="text-indent:25px">長管式防毒面具氣密性測試方法可以進行負壓密合性測試，也可以進行正壓密合性測試。負壓氣密性測試的操作方法為：將手掌蓋住防毒面具濾毒盒表面輕輕吸氣，面具應(yīng)有輕微的塌陷，并向臉部靠攏。如您感覺氣體從面部和防毒面具間漏進，請重新調(diào)整防毒面具位置和頭帶的松緊度，以達到密合良好。正壓氣密性測試的操作方法為：將手掌蓋住防毒面具呼氣閥并慢慢呼氣，面具應(yīng)向外輕輕膨脹，如氣體從您的面部和防毒面具間泄漏，重新調(diào)整防毒面具位置和頭帶的松緊度，達到密合良好。佩戴長管式防毒面具時不要讓頭帶和頭發(fā)壓在面罩密合框內(nèi)，也不能讓面罩的頭帶彎向面罩內(nèi)。另外，男性使用者在佩戴長管式防毒面具之前應(yīng)當(dāng)將自己的胡須剃刮干凈，以免影響接下來防毒面具密閉性檢測。遼寧防毒面具標(biāo)準防毒面具將各部件構(gòu)成一整體的主要部件是面具罩體。</p><div

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的纖維網(wǎng)格組成，氣溶膠微粒通過時，總會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，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，它取決于重力對氣流中粒子的吸引力，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，就會碰撞到纖維表面上被捕獲。擴散效應(yīng)較小粒子的運動受到和它相碰撞的空氣分子的影響，然后在空氣流做無規(guī)則的運動，通過時和纖維發(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)，特別是截留和擴散效應(yīng)。</p><p style="text-indent:25px">防毒面具中隔絕式防毒面具由面具自身供給氧氣，分貯氣式、貯氧式和化學(xué)生氧式3種。隔絕式面具首要在高濃度染毒空氣中，或在缺氧的高空、水下或密閉艙室等特別場合下運用,運用范圍具有一定的局限性。由于活性炭自身就具有必定的吸附有些毒氣的作用，首要是一些窒息性毒氣。如果是觸摸肌膚就會中毒的沾染性毒氣，通常防毒面具很難做到安全防護的程度，更不用說一些生物性或細菌性的環(huán)境，那有必要還需要全罩式防護服等來全副武裝進行防護。研究人員為了使濾毒罐對某些化學(xué)成分具有更強的選擇性與針對性，將活性炭與化學(xué)試劑徹底融合后，一些化學(xué)成分就會與活性炭上的試劑發(fā)作反應(yīng)，這類吸附表象即是吸附表象?；瘜W(xué)吸附力是化學(xué)結(jié)合，在運用過程中只需留意不發(fā)生穿透現(xiàn)象，而且做到要及時替換濾毒罐，通常不會呈現(xiàn)太大的安全隱患。所謂穿透即是活性炭的吸附作用現(xiàn)已飽滿，再繼續(xù)運用，現(xiàn)已不能再作用與它的過濾效果；所以，如果不及時替換濾毒罐，有毒有害氣體就會直接被工作人員所吸入，防毒面具也就失去了自身的價值。防毒面具主要用來阻斷經(jīng)呼吸道產(chǎn)生毒性的毒氣，對于生物毒劑的防護，也有一定的作用。</p><div

style="text-indent:25px">防毒面具過濾層的防毒性能。氣溶膠和蒸氣是2種不同的物態(tài)，其物理和運動特性也不盡相同，所以，過濾層過濾氣溶膠和吸附劑層吸著毒劑蒸氣，具有完全不同的特點。吸附劑層吸著毒劑時，一開始在吸附劑層的尾氣流中沒有毒劑分子透過，一段時間以后，尾氣中開始有毒劑分子出現(xiàn)，毒劑濃度由小變大，逐漸增加，較終達到防護的閾值而穿透面具過濾罐。而氣溶膠通過過濾層時，一開始就有煙霧透過，發(fā)生瞬時穿透，并且在通常情況下穿透濃度基本不變，不隨時間的延長而增大。在使用防毒面具時，應(yīng)根據(jù)生產(chǎn)環(huán)境中不同種類和性質(zhì)的有毒蒸氣、氣體、有害氣溶膠選擇合適的濾毒罐GB2890-1995中規(guī)定了8種類型的濾毒罐，其中帶過濾層的在罐上加注字母“L”。防毒面具是個人勞動保護用品，也是單兵防護用品。防霧霾防毒面具多少錢一副</p><p
