style="text-indent:25px">佩戴防毒面具時(shí)，使用者首先要根據(jù)自己的頭型大小選擇合適的面具。佩戴防毒面罩時(shí)，將中、上頭帶調(diào)整到適當(dāng)位置，并松開(kāi)下頭帶，用兩手分別抓住面罩兩側(cè)，屏住呼吸，閉上雙眼，將面罩下位罩住下巴，雙手同時(shí)向后上方用力撐開(kāi)頭帶，由下而上戴上面罩，并拉緊頭帶，使面罩與臉部確實(shí)貼合，然后深呼一口氣，睜開(kāi)眼睛。檢查面罩佩戴氣密性的方法是:用雙手掌心堵住呼吸閥體進(jìn)出氣口，然后猛吸一口氣，如果面罩緊貼面部，無(wú)漏氣即可，否則應(yīng)查找原因，調(diào)整佩戴位置直至氣密。</p><p style="text-indent:25px">防毒面具的吸附劑層，采用的是載有催化劑或化學(xué)吸著劑的活性炭。這種活性炭通常稱(chēng)為浸漬活性炭或浸漬炭，或稱(chēng)為防毒炭或催化炭?；钚蕴渴墙n炭的基礎(chǔ)，浸漬炭的防毒性能在很大程度上取決于活性炭的性能與質(zhì)量。在活性炭的過(guò)渡孔和大孔表面上，載有銅、銀、鉻或鉬、鋅等金屬氧化物，這就是浸漬活性炭。這些金屬氧化物的加入數(shù)量，對(duì)防毒性能影響較大。除添加這些金屬氧化物外，為進(jìn)一步提高防毒性能和穩(wěn)定性，有的浸漬炭上還加有少量的堿（氫氧化鈉）、氮苯、葡萄糖、三乙二胺之類(lèi)的化學(xué)藥劑。防毒面具普遍應(yīng)用于石油、化工、礦山、冶金、***、消防、搶險(xiǎn)救災(zāi)、衛(wèi)生防疫和科技環(huán)保、機(jī)械制造等領(lǐng)域。</p><div

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(chǎng)合下運(yùn)用,運(yùn)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(huì)中毒的沾染性毒氣，通常防毒面具很難做到安全防護(hù)的程度，更不用說(shuō)一些生物性或細(xì)菌性的環(huán)境，那有必要還需要全罩式防護(hù)服等來(lái)全副武裝進(jìn)行防護(hù)。研究人員為了使濾毒罐對(duì)某些化學(xué)成分具有更強(qiáng)的選擇性與針對(duì)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(huì)與活性炭上的試劑發(fā)作反應(yīng)，這類(lèi)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(yùn)用過(guò)程中只需留意不發(fā)生穿透現(xiàn)象，而且做到要及時(shí)替換濾毒罐，通常不會(huì)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(yùn)用，現(xiàn)已不能再作用與它的過(guò)濾效果；所以，如果不及時(shí)替換濾毒罐，有毒有害氣體就會(huì)直接被工作人員所吸入，防毒面具也就失去了自身的價(jià)值。防毒面具的重要組成部分是面罩。防毒面具批發(fā)制造</p><p

style="text-indent:25px">根據(jù)防毒面具的固定形式，可以分為頭帶式防毒面具，就是用具有彈性的頭帶將面具本體與使用者面部緊密的貼合，從而有效的隔絕外部有毒氣體與人體呼吸道，頭帶式防毒面具優(yōu)點(diǎn)在于面具尺寸規(guī)格比較齊全，一般分為大中小三個(gè)型號(hào)，面具的密封性好，且聽(tīng)力不受任何影響，缺點(diǎn)在于佩戴步驟復(fù)雜，不太方便；頭罩式防毒面具，它是面罩主體直接將整個(gè)頭部罩起來(lái)，較大的優(yōu)勢(shì)在于佩戴方便，且佩戴后面罩的穩(wěn)定性和氣密性相對(duì)頭帶式防毒面具更好，劣勢(shì)在于佩戴后，頭部的壓力較大，聽(tīng)力相對(duì)減弱，靈活性稍微差一些。重型防毒面具定制</p><p
