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，對光氣的防護(hù)能力會有所提高。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)，河北正壓式防毒面具，過濾罐失效以后還可以再生。防毒面具普遍應(yīng)用于石油、化工，河北正壓式防毒面具、礦山、冶金、***、消防、搶險(xiǎn)救災(zāi)，河北正壓式防毒面具、衛(wèi)生防疫和科技環(huán)保、機(jī)械制造等領(lǐng)域。河北正壓式防毒面具</p><div

style="text-indent:25px">防毒面具主要用來阻斷經(jīng)呼吸道產(chǎn)生毒性的毒氣，如氯化氰（CK）、氯化苦（PS）等；對于生物毒劑的防護(hù)，也有一定的作用。在《禁止化學(xué)武器公約》生效后，防毒面具的需求曾一度降低；但隨著全球反恐行動(dòng)的加強(qiáng)，潛在的化學(xué)襲擊的威脅依舊存在，防毒面具依舊是化學(xué)防護(hù)的重要器材，在各國的**中都有相當(dāng)?shù)难b備量。此外，在有毒有害氣體環(huán)境下工作的人群也在使用防毒面具作為防護(hù)；但一般民用防毒面具的結(jié)構(gòu)沒有***的復(fù)雜，各項(xiàng)指標(biāo)也不如***的嚴(yán)格。針對民用的化學(xué)防護(hù)，設(shè)計(jì)出更多的外觀，來適應(yīng)不同人群的需要。廣州防毒面具哪個(gè)牌子好防毒面具可以說是模仿豬嘴的一件杰作。</p><div

style="text-indent:25px">防毒面具作為個(gè)人防護(hù)器材，用于對人員的呼吸***，眼睛及面部皮膚提供有效防護(hù)。面具由面罩，導(dǎo)氣管和濾毒罐組成，面罩可直接與濾毒罐或?yàn)V毒盒連接使用，稱為直連式；或者用導(dǎo)氣管與濾毒罐和濾毒盒連接使用，稱為導(dǎo)管式。防毒面罩可以根據(jù)防護(hù)要求分別選用各種型號的濾毒罐，應(yīng)用在化工、倉庫、科研、各種有毒、有害的作業(yè)環(huán)境。防毒面具主要是由過濾元件、罩體、眼窗、呼氣通話裝置以及頭帶等部件組成，它們各有各的職責(zé)，同時(shí)又能默契配合。</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。這種活性炭通常稱為浸漬活性炭或浸漬炭，或稱為防毒炭或催化炭。浸漬活性炭的催化作用是指某些難被物理吸附和化學(xué)吸附的有毒蒸氣，采用催化劑使之發(fā)生催化反應(yīng)，可以卓著提高化學(xué)反應(yīng)速度，例如銅和鉻的氧化物與難以吸附的氯化氰、**等起水解反應(yīng)。浸漬炭上發(fā)生的催化反應(yīng)，主要是空氣中的氧和水，在催化劑的作用下，與毒劑發(fā)生反應(yīng)。應(yīng)當(dāng)指出，催化劑在反應(yīng)中只是提高了化學(xué)反應(yīng)的速度，本身并未發(fā)生化學(xué)變化，且會逐漸被反應(yīng)生成物所覆蓋，而失去催化作用。防毒面具上的濾毒罐上面出現(xiàn)了小孔，那么可以用你的手或者是其它的材料來將其堵住并及時(shí)撤離。</p><div

style="text-indent:25px">防毒面具過濾層的防毒性能。氣溶膠和蒸氣是2種不同的物態(tài)，其物理和運(yùn)動(dòng)特性也不盡相同，所以，過濾層過濾氣溶膠和吸附劑層吸著毒劑蒸氣，具有完全不同的特點(diǎn)。吸附劑層吸著毒劑時(shí)，一開始在吸附劑層的尾氣流中沒有毒劑分子透過，一段時(shí)間以后，尾氣中開始有毒劑分子出現(xiàn)，毒劑濃度由小變大，逐漸增加，較終達(dá)到防護(hù)的閾值而穿透面具過濾罐。而氣溶膠通過過濾層時(shí)，一開始就有煙霧透過，發(fā)生瞬時(shí)穿透，并且在通常情況下穿透濃度基本不變，不隨時(shí)間的延長而增大。在使用防毒面具時(shí)，應(yīng)根據(jù)生產(chǎn)環(huán)境中不同種類和性質(zhì)的有毒蒸氣、氣體、有害氣溶膠選擇合適的濾毒罐GB2890-1995中規(guī)定了8種類型的濾毒罐，其中帶過濾層的在罐上加注字母“L”。河北正壓式防毒面具</p><p
