style="text-indent:25px">防毒面具面罩的防護(hù)效果取決于面罩各個(gè)接口的氣密性，如眼窗、通話器、過濾罐等部位接口的氣密性，即平常所說的面罩裝配氣密性。另外，我們可以將面罩密合框與人員頭面部的密合部位也看作一個(gè)接口，這就是面罩較大接口的氣密性問題，也是面罩在使用時(shí)較重要的佩戴氣密性問題。?在面罩罩體的內(nèi)側(cè)周邊有密合框，它是面罩與佩戴者面部貼合的部分或部件，由橡膠材料制成。在雙目式和單目式面罩結(jié)構(gòu)中，密合框與罩體主體是一個(gè)整體部件;在全臉式面罩結(jié)構(gòu)中，密合框是一個(gè)**的部件。密合框的功能是將面罩內(nèi)部空間與外部空間隔絕，防止有毒、有害氣體漏入面罩內(nèi)部空間，保障防毒面具的呼吸系統(tǒng)正常工作，確保防毒面具的防護(hù)性能。在使用防毒面具之前，應(yīng)該對(duì)其進(jìn)行認(rèn)真的檢查。</p><div

style="text-indent:25px">防毒面具中的浸漬活性炭通過如下3種作用來達(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的化學(xué)性質(zhì)，吸附熱較低，無選擇性，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?；瘜W(xué)吸附是由吸附質(zhì)與吸附劑分子之間以類似化學(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，所以過濾罐吸收**氫之類的毒劑失效以后，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)，過濾罐失效以后還可以再生。防毒面具主要用來阻斷經(jīng)呼吸道產(chǎn)生毒性的毒氣，對(duì)于生物毒劑的防護(hù)，也有一定的作用。普通防毒面具多少錢</p><p
