防護口罩的過濾機制：1.擴散沉積：粒子布朗運動擴散位移到過濾纖維，受分子引力作用而被吸附。很容易捕捉小尺度粒子、細纖維和低速運動的粒子。2.截留沉積：隨氣流運動的較大粒子被過濾材料的機械篩濾作用截留。粒子直徑與濾膜纖維的直徑的比率影響攔截效率。3.慣性沉積：粒子通過過濾材料彎曲的網(wǎng)狀通道時，粒子由于慣性作用脫離氣流撞擊過濾纖維，并受分子引力作用被截留。大粒子、高密度、速度快時截留效果好。4.靜電吸引沉積：粒子被過濾纖維的靜電作用產(chǎn)生的沉積。顆粒越小時，安全防護口罩廠家批發(fā)，1、4沉積效應(yīng)越強，顆粒越大時，2、3效果越好，所以并非越小的顆粒越難被過濾，安全防護口罩廠家批發(fā)。綜合4種過濾機制的協(xié)同作用，安全防護口罩廠家批發(fā)，普通機械性濾料極易穿透粒徑的范圍是μm～μm。沒有防毒面具或特殊型的防護口罩，也可采用容易得到的材料制造簡便的呼吸道防護用具。安全防護口罩廠家批發(fā)</p><div
