style="text-indent:25px">防護(hù)口罩防護(hù)原理：用于過(guò)濾顆粒物的材料有礦物性纖維、天然纖維或合成纖維，濾料纖維對(duì)空氣中的顆粒物進(jìn)行過(guò)濾的機(jī)理分為五種，它們可以綜合起作用。沉降作用：大顆粒物質(zhì)在氣流中受重力影響沉降到濾料上，從氣流中分離；慣性撞擊作用：當(dāng)氣流中的顆粒物繞過(guò)阻擋在氣流前方的濾料纖維時(shí)，較高質(zhì)量的顆粒物受慣性影響會(huì)偏離氣流方向，撞到濾料纖維上被過(guò)濾下來(lái)；攔截作用：顆粒在氣流中處于較靠近濾料的流線(xiàn)上，因顆粒的半徑大于流線(xiàn)與濾料之間的距離而被濾料“刮蹭”而攔截下來(lái)；擴(kuò)散作用：受空氣分子熱運(yùn)動(dòng)影響，極其微小的顆粒受到空氣分子的撞擊，不斷改變運(yùn)動(dòng)方向，呈現(xiàn)布朗運(yùn)動(dòng)，隨機(jī)性地接觸到濾料纖維被過(guò)濾下來(lái)。防護(hù)口罩哪個(gè)牌子好？</p><div

5微米以下的呼吸性粉塵的阻隔效率為標(biāo)準(zhǔn)。因?yàn)檫@一粒徑的粉塵能直接入肺泡，對(duì)人體健康造成的影響比較大。一般的紗布口罩，其阻塵原理是機(jī)械式過(guò)濾，就是當(dāng)粉塵沖撞到紗布時(shí)，經(jīng)過(guò)—層層的阻隔,將一些大顆粒粉塵阻隔在沙布中。但是，對(duì)一些微細(xì)粉塵，尤其是小于 5微米的粉塵，就會(huì)從紗布的網(wǎng)眼中穿過(guò)去，進(jìn)入呼吸系統(tǒng)。現(xiàn)國(guó)外有一些防塵口罩，其濾料由充上長(zhǎng)久靜電的纖維組成，那些小于 5微米的呼吸性粉塵在穿過(guò)此種濾料的過(guò)程中，被靜電吸引而吸附在濾料捕獲到微細(xì)粉塵，真正起到阻塵作用。醫(yī)用防護(hù)口罩適用范圍：有毒化學(xué)、礦山工作人員，花粉過(guò)敏人員。中山兒童防護(hù)口罩</p><p style="text-indent:25px">防護(hù)口罩的種類(lèi)及特點(diǎn)。中山兒童防護(hù)口罩</p><p> 防護(hù)口罩分為兩類(lèi)：工業(yè)用顆粒物防護(hù)口罩（比如N95）和醫(yī)用防護(hù)口罩。對(duì)于普通人來(lái)說(shuō)，兩種口罩都可以使用。1.工業(yè)用顆粒物防護(hù)口罩。通常執(zhí)行美國(guó)N95、中國(guó)KN95、歐洲FFP2、日本DS2等標(biāo)準(zhǔn)；這些標(biāo)準(zhǔn)是指阻隔直徑大小約為微米的顆粒物。而飛沫指直徑大于5微米的氣溶膠（顆粒物），因此普通人也可以使用工業(yè)用顆粒物防護(hù)口罩。測(cè)試標(biāo)準(zhǔn)稍有不同，測(cè)試的顆粒不同，F(xiàn)FP2是油性與非油性都可過(guò)濾，美國(guó)有油性的R和P標(biāo)準(zhǔn)，中國(guó)有油性的KP的效率達(dá)到95%(FFP2為94%)。數(shù)字越大，dai表過(guò)濾能力越強(qiáng)，如N99、N100、FFP3標(biāo)準(zhǔn)的口罩，也有阻隔效率差一點(diǎn)的，比如KN90和FFP1口罩。大家可以推薦N95、KN95等口罩，KN90次之。2.醫(yī)用防護(hù)口罩不僅滿(mǎn)足對(duì)非油性顆粒物至少95%過(guò)濾效率要求（但不一定都獲得了N95認(rèn)證），還具有阻隔血液或傳染性體液噴濺的能力，更適合醫(yī)務(wù)人員臨床使用。例如3M1860/1860s、9132等。中山兒童防護(hù)口罩</p></p><br
