style="text-indent:25px">防毒面具應(yīng)用越來越普遍，而防毒面具的設(shè)計研發(fā)就非常重要，特別是防毒面具的密合性。為什么這樣說呢？使用到防毒面具的場合必定是含有毒物質(zhì)的，如果被人直接吸到肺部，后果不堪設(shè)想。防毒面具雖然能夠有效過濾有毒物質(zhì)，但防毒面具本體與人體面部的密閉性好壞，將直接決定防護性能。根據(jù)物理學中氣流力體學原***流優(yōu)先流向阻力較小的方向，如果防毒面具與人體面部產(chǎn)生微小的縫隙，因為面具內(nèi)部壓力原因，吸進人體的氣體并非是經(jīng)過濾毒盒過濾后的氣體，而是穿過縫隙的外界有毒氣體，所以說防毒面具的沒有實際的防護效果。另外當防毒面具本體與臉型不相吻合，也會造成佩戴者的不舒適感，影響用戶的體驗。</p><p style="text-indent:25px">防毒面具連接后的氣密性檢查。在檢查完各部件以后，對整體防毒面具氣密性的檢查很重要。簡易檢查方法是：打開橡膠底塞吸氣，此時如沒有空氣進入，則證明連接正確，如有漏氣，則應(yīng)檢查各部位連接正確與否。應(yīng)根據(jù)勞動強度和作業(yè)環(huán)境空氣中有害物濃度選用不同類型的防毒面具。如低濃度的作業(yè)環(huán)境可選用小型濾毒罐的防毒面具。應(yīng)嚴格遵守濾毒罐的有效時間。在使用過程必須記錄濾毒罐使用過的時間、毒物性質(zhì)、濃度等。若記錄卡片上累計使用時間達到濾毒罐規(guī)定的時間，應(yīng)立即停止使用。在使用過程中嚴禁隨意擰開濾毒罐(盒)的蓋子，并防止水或其它液體進入罐(盒)中。該產(chǎn)品不得在65。C以上環(huán)境中使用及高溫環(huán)境中存放。濾毒罐吸濕后會降低防毒能力，平時應(yīng)擰緊罐蓋，扣好底塞，以防進水。防毒呼吸面具的眼窗鏡片，應(yīng)防劃痕磨擦，保持視物清晰。防毒呼吸用品應(yīng)專人使用和保管，使用后應(yīng)清洗，消毒。在清洗和消毒時，應(yīng)注意溫度，不可使橡膠等部件因受溫度影響而發(fā)生質(zhì)變受損。防毒面具的吸附劑層，采用的是載有催化劑或化學吸著劑的活性炭。</p><div

style="text-indent:25px">防毒面具過濾層是專門用來過濾有害氣溶膠的。生產(chǎn)過程中產(chǎn)生的毒煙(固體微粒)、毒霧(液體微粒)、放射性灰塵和含細菌、病毒的微粒等，稱為有害氣溶膠。過濾層對有害氣溶膠的過濾過程與氣溶膠微粒的化學性質(zhì)關(guān)系不大，主要與其物理性質(zhì)、運動特性有關(guān)。過濾層過濾氣溶膠的過程。目前常用的玻璃纖維過濾層是由許多層縱橫交錯的纖維網(wǎng)格組成，氣溶膠微粒通過時，總有機會接觸到纖維而被阻留。發(fā)生這種接觸的諸多效應(yīng)中，主要是截留效應(yīng)、慣性效應(yīng)、擴散效應(yīng)和靜電效應(yīng)等4種，其中起主要作用的又是**種效應(yīng)。濾煙層有2種:完全的與非完全的。完全的濾煙層采用過濾材料除去空氣中的粒子，也就是說，過濾材料將大于孔隙的粒子擋在外面。然而，大部分面具的濾煙層是非完全濾煙層，這意味著它們含有比要除去的粒子直徑大的孔隙，利用截留、沉降、慣性、擴散和靜電效應(yīng)的組合來去除粒子。真正發(fā)揮作用的組合過濾機理取決于粒子通過濾煙層的速率和粒子的尺寸，起主要作用的又是截留效應(yīng)、慣性效應(yīng)和擴散效應(yīng)。防毒面具對于生物毒劑的防護，也有一定的作用。山西防毒面具廠家批發(fā)</p><p

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)。江蘇防毒面具</p><p
