style="text-indent:25px">過(guò)濾式防毒面具和長(zhǎng)管式防毒面具分別屬于不同類型的產(chǎn)品，過(guò)濾式防毒面具屬于過(guò)濾式呼吸防護(hù)用品設(shè)備，長(zhǎng)管式防毒面具屬于隔絕式呼吸防護(hù)用品設(shè)備，從外觀上看，可以看的出，過(guò)濾式防毒面具由防毒面罩和濾毒罐連接組成，長(zhǎng)管式防毒面具由防毒面罩和通氣長(zhǎng)管組成，這是二者明顯的區(qū)別，也就是說(shuō)，當(dāng)人使用過(guò)濾式防毒面具的時(shí)候，防毒面具使用者呼吸的是所處環(huán)境中的經(jīng)過(guò)濾毒罐吸附過(guò)濾掉毒氣后的空氣，而長(zhǎng)管式防毒面具的進(jìn)氣端安置在被污染環(huán)境之外的安全空氣中，使用者呼吸的是安全環(huán)境中的空氣，這也是過(guò)濾式呼吸防護(hù)用品和隔絕式呼吸防護(hù)用品的主要區(qū)別。</p><p style="text-indent:25px">化工防毒面具中進(jìn)階型一：自吸式長(zhǎng)管呼吸器防護(hù)級(jí)別高于自吸式防毒面具，它的原理很簡(jiǎn)單，就是防毒面具面罩的本體上接上一根長(zhǎng)管，長(zhǎng)管的另一端放置在干凈的氣源處。憑借自身的肺力吸進(jìn)新鮮空氣，從而保護(hù)人體呼吸。自吸式長(zhǎng)管空氣呼吸器是一種比較廉價(jià)的化工防毒面具，人體作業(yè)的環(huán)境相對(duì)比較密封，比如對(duì)容器罐的清理，這款就是不錯(cuò)的選擇。進(jìn)階型二：送風(fēng)式長(zhǎng)管呼吸器相對(duì)系列比較廣，較為常見(jiàn)的數(shù)電動(dòng)送風(fēng)長(zhǎng)管呼吸器，它的優(yōu)勢(shì)相對(duì)前兩者更加明顯，呼吸器不收環(huán)境限制、不受作業(yè)時(shí)間限制，更為重要的是，可以同時(shí)多人作業(yè)，提升效率。送風(fēng)式長(zhǎng)管呼吸器利用送風(fēng)機(jī)不斷地給面罩提供充足空氣，即使臉部與面罩之間出現(xiàn)輕微縫隙，也并不影響正常工作，更加不必?fù)?dān)心有害氣體無(wú)法進(jìn)入面罩內(nèi)。防毒面具是保護(hù)人員呼吸系統(tǒng)、眼睛及面部免受毒劑和放射性灰塵等有害物質(zhì)傷害的個(gè)人防護(hù)器材。</p><div

style="text-indent:25px">防毒面具中的浸漬活性炭通過(guò)如下3種作用來(lái)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(lái)的化學(xué)性質(zhì)，吸附熱較低，無(wú)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(lái)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(guò)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(guò)濾罐失效以后還可以再生。防毒面具上的頭罩被破壞，可以考慮將濾毒罐直接的放在嘴里，然后再捏住鼻子，用濾毒罐來(lái)呼吸就好了。小型防毒面具多少錢(qián)</p><p
