class="box"><p><p style="text-indent:25px">現(xiàn)在市場(chǎng)上家用防毒面具有很多種類(lèi)型，其中根據(jù)防毒面具的固定形式，可以分為頭帶式和頭罩式兩種：頭帶式防毒面具，遼寧負(fù)壓式防毒面具，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。兩種家庭防毒面具相對(duì)而言，小編更建議選用頭罩式防毒面具，因?yàn)橐坏┌l(fā)生火災(zāi)，佩戴時(shí)間越短，遼寧負(fù)壓式防毒面具，求生的機(jī)率相對(duì)更大些。那么我們?cè)谶x購(gòu)家用防毒面具時(shí)，遼寧負(fù)壓式防毒面具，需要注意什么呢？網(wǎng)上有很多種說(shuō)法，比如防毒面具舒適性、面具的材質(zhì)、面具做工細(xì)節(jié)以及面具的密合性，這里我們較重要的，是要注重防毒面具的密閉性能，如果在火災(zāi)中佩戴，面具與面部發(fā)生縫隙，那么煙霧有毒氣體滲透進(jìn)去，也會(huì)造成嚴(yán)重的后果。工業(yè)防毒面具是否真正起到防護(hù)作用。遼寧負(fù)壓式防毒面具</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="遼寧負(fù)壓式防毒面具,防毒面具"

style="text-indent:25px">防毒面具主要依靠濾毒罐防毒，其中的裝填物由吸附劑層和過(guò)濾層構(gòu)成，其中吸附劑層濾除有毒氣體和蒸汽，過(guò)濾層則過(guò)濾有害氣溶膠。因?yàn)閷?duì)蒸汽狀毒劑的吸著和對(duì)有害氣溶膠的過(guò)濾過(guò)程不同，防毒原理也不同。吸附劑層的防毒原理吸附劑層中，用的是載有催化劑的活性炭，即浸漬活性炭，這種經(jīng)過(guò)活化處理的無(wú)定形炭是多孔吸附劑，主要成分是碳，含量約為80%～98%，另有少量灰分?；钚蕴康目紫兑话惴譃槲⒖?、過(guò)渡孔、大孔3類(lèi)，有時(shí)過(guò)渡孔也稱(chēng)為中孔。微孔較小，有效半徑0.5～1納米，上限為1.5納米，所占的全部容積約為0.15～0.5厘米3/克。由于這類(lèi)孔小而數(shù)量多，所形成的比表面積約占活性炭比表面積總數(shù)的90%以上，活性炭對(duì)毒劑蒸氣的吸附主要靠它。因此微孔的多少和分布在很大程度上決定某種特定活性炭的吸附能力。在吸附過(guò)程中，這三種孔隙互相連通，微孔在內(nèi)，過(guò)渡孔和大孔在吸附過(guò)程中起通道作用。過(guò)渡孔和大孔表面載有銅、銀、鉻或鉬、鋅等金屬氧化物，它們的加入數(shù)量對(duì)防毒性能影響較大。遼寧負(fù)壓式防毒面具防毒面具主要是由過(guò)濾元件、罩體、眼窗、呼氣通話裝置以及頭帶等部件組成。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="遼寧負(fù)壓式防毒面具,防毒面具"

style="text-indent:25px">工業(yè)防毒面具是否真正起到防護(hù)作用，除了選擇防護(hù)功能外，另一個(gè)重要選擇因素是適合性。沒(méi)有一個(gè)多功能的設(shè)計(jì)能適合所有人的臉型。工業(yè)防毒面具的認(rèn)證檢測(cè)并不保證防毒面具適合每個(gè)具體的使用者，如果存在泄漏，空氣中的污染物就會(huì)從泄漏處進(jìn)入呼吸區(qū)。其中開(kāi)發(fā)的兩款防毒面具，N90防毒面具能夠有效過(guò)濾PM2.5二十分之一大小的微粒粉塵，并且專(zhuān)門(mén)針對(duì)亞洲人臉型進(jìn)行設(shè)計(jì)，面部貼合相對(duì)其他品牌做的要好一些。選擇適合的防毒面具的方法是使用適合性檢驗(yàn)，它利用人的味覺(jué)，用**工具發(fā)生苦味或甜味的顆粒物，如果戴防毒面具后仍然能夠感覺(jué)到味道，說(shuō)明防毒面具存在泄漏。防毒面具使用后請(qǐng)盡量平放保存于清潔干燥處，避免折疊，以免造成鼻梁條損壞。防毒面具受污染如染有血漬或飛沫等異物、使用者感到呼吸阻力變大、防毒面具損毀等情況要立即更換。</p><p 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。防毒面具在個(gè)人防護(hù)用品中屬于一等級(jí)，高于耳罩和防護(hù)眼鏡等。</p><div

style="text-indent:25px">半面罩只能防護(hù)口鼻部位，而罩是針對(duì)整個(gè)面部的防護(hù)。如果使用的環(huán)境有噴濺的液體或是毒氣對(duì)皮膚有刺激性，那么佩戴具更加安全。如果是一般的毒氣防護(hù)，且沒(méi)有液體噴濺，可以使用半面罩，因?yàn)榘朊嬲值囊曇跋鄬?duì)罩更寬廣。一個(gè)合格的防護(hù)產(chǎn)品，必須要有**機(jī)構(gòu)的認(rèn)證，才是對(duì)使用者真正安全的保障。比如國(guó)產(chǎn)的防毒面具需要通過(guò)中國(guó)LA認(rèn)證；而國(guó)外的，一般防毒面具認(rèn)證**機(jī)構(gòu)有美國(guó)職業(yè)安全健康研究所（NIOSH）、歐洲的CE認(rèn)證、日本的MHLW認(rèn)證、韓國(guó)的KMOL認(rèn)證等。防毒面罩可以根據(jù)防護(hù)要求分別選用各種型號(hào)的濾毒罐。遼寧負(fù)壓式防毒面具</p><p

style="text-indent:25px">防毒面具：過(guò)濾元件是防毒面具上忠誠(chéng)的把關(guān)衛(wèi)士，它只允許人體的清潔空氣通過(guò)。世界各國(guó)的面具五花八門(mén)，面具上的過(guò)濾元件也是形狀各異，但它們內(nèi)部結(jié)構(gòu)的設(shè)計(jì)思路卻大同小異。其內(nèi)部裝有對(duì)付懸浮在空氣中的微小顆粒的過(guò)濾層，又叫濾煙層，實(shí)際上是一層特制過(guò)濾紙。它既要高效率地濾除有害物氣溶膠粒子，又要對(duì)人體的呼吸不產(chǎn)生明顯的阻力。過(guò)濾元件內(nèi)還裝有專(zhuān)門(mén)對(duì)付毒氣蒸氣的防毒炭。它跟普通民用活性炭不同，防毒炭不僅要有非常發(fā)達(dá)的微孔結(jié)構(gòu)，使其有足夠大的“肚子”，能盡量多“吃”毒劑，而且要有充分發(fā)達(dá)的中孔、大孔，以使具有吸附作用的道路暢通，滿足吸附速率的要求。防毒炭除要求孔隙結(jié)構(gòu)合理外，還須經(jīng)特殊的化學(xué)藥劑處理，因?yàn)?，?duì)付各種毒魔單靠物理吸附作用是遠(yuǎn)遠(yuǎn)不夠的，必須借助催化劑，進(jìn)行物化反應(yīng)，使其大量“吸毒”，成為身手不凡的“癮君子”。遼寧負(fù)壓式防毒面具</p><p
