防護(hù)口罩的重要性。在霧靄天出去時(shí)，我們zui好把口罩戴上，口罩防止吸入空氣中的污染物。下面我們來(lái)看一下如何正確選擇口罩應(yīng)對(duì)空氣污染?？谡值恼Q生和發(fā)展當(dāng)然，發(fā)明口罩的初衷絕非是作為面具使用。1861年，巴斯德發(fā)現(xiàn)空氣中有病菌存在，繼而可能造成手術(shù)傷口感ran。于是在十九世紀(jì)末，醫(yī)生和護(hù)士們開(kāi)始用紗布來(lái)遮掩口鼻。此后，這種口罩的雛形經(jīng)過(guò)了多次改良，逐漸變成現(xiàn)在這副模樣。1918年，西班牙大流感肆虐，口罩才從醫(yī)院走出來(lái)，成為大眾的常備品。起初，人們使用的是用多層脫脂紗布制成的口罩。紗布口罩厚實(shí)而吸汗，可重復(fù)使用，易于洗滌，價(jià)錢(qián)便宜。實(shí)驗(yàn)證明，具備足夠?qū)訑?shù)的紗布口罩能夠?yàn)V除相當(dāng)一部分粉塵和細(xì)菌，長(zhǎng)期以來(lái)一直是人們使用zui多的口罩類(lèi)型。不過(guò)，隨著人們防塵要求的提高，紗布口罩已逐漸難以滿(mǎn)足要求。城市空氣中可吸入顆粒物和細(xì)粒子的危害已越來(lái)越引起大眾的重視，而紗布口罩對(duì)于顆粒物的過(guò)濾率還不到30%。在環(huán)境改良難以一朝一夕完成的背景下，找一副靠得住的口罩來(lái)濾過(guò)糟糕的空氣也就成了zui實(shí)用zui簡(jiǎn)便的個(gè)人防護(hù)方式。 </p><p> 防護(hù)口罩的防護(hù)原理。防護(hù)口罩主要是用于過(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。1.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；2.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)；3.攔截作用：顆粒在氣流中處于極靠近濾料的流線(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)；4.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)；5.靜電作用：如果濾料纖維帶有微弱的靜電，無(wú)論氣流中的顆粒物本身是否帶靜電，當(dāng)它們靠近濾料纖維時(shí)就容易受靜電吸引而被過(guò)濾下來(lái)，靜電作用可以幫助過(guò)濾材料在不增加氣流阻力的前提下提高過(guò)濾效率。防護(hù)口罩使用過(guò)程中的注意事項(xiàng)。</p><div
