class="box"><p><p style="text-indent:25px">防毒面具過(guò)濾式由面罩和濾毒罐（或過(guò)濾元件）組成。面罩包括罩體、眼窗、通話器、呼吸活門和頭帶（或頭盔）等部件。濾毒罐用以凈化有毒氣體，內(nèi)裝濾毒層和吸附劑，也可將這 2 種材料混合制成過(guò)濾板，裝配成過(guò)濾元件。較輕的（200克左右）濾毒罐或過(guò)濾元件可直接連在面罩上，較重的濾毒罐通過(guò)導(dǎo)氣管與面罩連接。隔絕式由面具本身提供氧氣，分貯氣式、貯氧式和化學(xué)生氧式 3 種。隔絕式面具主要在高濃度染毒空氣（體積濃度大于 1 %時(shí)）中，湖南學(xué)生防毒面具，或在缺氧的高空，湖南學(xué)生防毒面具、水下或密閉艙室等特殊場(chǎng)合下使用。除上述2 種防毒面具以外，許多國(guó)家還裝備有各類防毒面具。它是在過(guò)濾式防毒面具的基礎(chǔ)上更換濾毒罐內(nèi)的吸著劑或改進(jìn)局部結(jié)構(gòu)而成?，F(xiàn)代防毒面具能有效地防御戰(zhàn)場(chǎng)上可能出現(xiàn)的毒劑、生物戰(zhàn)劑和放射性灰塵。它的重量有的已減至0.6千克左右，可持續(xù)佩戴8小時(shí)以上，佩戴防毒面具后還可較方便地使用光學(xué)，湖南學(xué)生防毒面具、通信器材和武器裝備。防毒面具的防毒時(shí)間同選定濾毒罐的性能。湖南學(xué)生防毒面具</p><div

style="text-indent:25px">除了正確佩戴防毒面具，關(guān)于噴漆防護(hù)方案也是你必須要了解的。面具品牌不同種類噴漆防毒面具，其防護(hù)效果不同，市面上常見(jiàn)的噴漆防毒面具品牌有3M防毒面具、霍尼韋爾(巴固)、代爾塔等等。防毒面具價(jià)格與面罩品牌、面罩材質(zhì)、面罩類型及佩戴舒適性相關(guān)。油漆中的有毒有害物均屬于有機(jī)氣體及顆粒物，所以噴漆防毒面具濾毒盒的選擇一定要具備防有機(jī)蒸氣的特性。面具類型噴漆防毒面具類型基本分為兩種：自吸過(guò)濾式防毒面具和隔絕式防毒面具。自吸過(guò)濾式噴漆防毒面具大多用于汽車4S店、五金店等作業(yè)場(chǎng)合空曠通風(fēng)、氧氣濃度高的環(huán)境中；而隔絕式噴漆防毒面具，大多為長(zhǎng)管呼吸器（或空氣呼吸器），用于缺氧、漆霧濃度高及密閉空間，如密閉的油罐、鍋爐等。吉林防霧霾防毒面具防毒面具的外形和豬嘴極為相似。</p><div

style="text-indent:25px">防毒面具主要用來(lái)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(duì)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(guó)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(méi)有***的復(fù)雜，各項(xiàng)指標(biāo)也不如***的嚴(yán)格。針對(duì)民用的化學(xué)防護(hù)，設(shè)計(jì)出更多的外觀，來(lái)適應(yīng)不同人群的需要。防毒口罩一般由濾毒盒或?yàn)V毒罐和面罩主體組成。</p><div

style="text-indent:25px">面罩是防毒面具的重要組成部分，是使人員面部與外界染毒空氣隔離的部件。面罩一般由罩體、阻水罩(導(dǎo)流罩)、眼窗、通話器、呼(吸)氣活門及頭帶組成，有的還根據(jù)需要設(shè)置有****鏡片面罩的分類面罩根據(jù)固定系統(tǒng)的不同，可分為頭盔式、頭帶式和網(wǎng)罩式3種;根據(jù)眼窗的數(shù)量和大小，可分為雙目式、單目式和全臉式3種。頭盔式面罩的主體與頭頂部分連在一起，具有佩戴方便，佩戴后穩(wěn)定性和氣密性好等特點(diǎn)，但缺點(diǎn)是對(duì)頭面部的壓痛較大，影響聽(tīng)力，且對(duì)人員面型的尺寸變異范圍適應(yīng)性差，滿足全體人員面型所需要的面罩規(guī)格較多。頭帶式面罩是用頭帶或頭罩將面罩固定在人員的面部，優(yōu)點(diǎn)是對(duì)人員頭型和尺寸的適應(yīng)性強(qiáng)，面罩規(guī)格少，不影響聽(tīng)力，缺點(diǎn)是佩戴相對(duì)較復(fù)雜，增加了對(duì)密合框的壓力。網(wǎng)罩式則綜合了上述2種固定系統(tǒng)的優(yōu)點(diǎn)。防毒面具從造型上可以分為各個(gè)方面具和半面具，各個(gè)方面具又分為正壓式和負(fù)壓式。甘肅69式防毒面具</p><p
