兒童佩戴防護(hù)口罩。兒童戴口罩必須留意下列四點(diǎn)：一是口罩的選擇，需選擇尺寸合適少年兒童的口罩。一般1歲以下小孩不宜戴口罩，有室息的風(fēng)險(xiǎn)性；市面上口罩有1歲和4歲左右不一樣種類，父母可依據(jù)孩子的年紀(jì)選擇。不能用成人口罩替代孩子的口罩，成人口罩過大，少年兒童戴上密合關(guān)不緊，起不上安全防范的功效。二是看中口罩的種類，孩子一般可選擇醫(yī)用外科口罩或N95醫(yī)用安全防護(hù)口罩，針對非**多發(fā)地域的孩子，用一次性醫(yī)用口罩就可以。棉布口罩、紗布口罩、海綿口罩均不能提供合理安全防護(hù)。三是父母要協(xié)助或是教會(huì)孩子恰當(dāng)佩戴口罩：操作前洗手，正確認(rèn)識口罩的正反兩面，淺灰色要正對面部，深棕色靠外；為孩子佩戴口罩時(shí)，口罩綁帶要緊松適當(dāng)；將口罩佩戴結(jié)束后，必須用兩手卡緊鼻梁骨兩邊的金屬材料條，使口罩上方緊靠鼻梁骨，隨后往下拉伸口罩，使口罩兩邊沒留有皺褶，遮住鼻頭、嘴唇及下頜；保證貼合肌膚，不漏氣。四是留意口罩內(nèi)外不可以更替應(yīng)用；應(yīng)用中防止觸碰口罩的外側(cè)邊；假如觸碰了外側(cè)邊，要立即冼手；較好不要多次重復(fù)使用一次性口罩。佛山鴨嘴型防護(hù)口罩標(biāo)準(zhǔn)不要用手去擠壓防護(hù)口罩。</p><div

防護(hù)口罩的防護(hù)原理。防護(hù)口罩主要是用于過濾顆粒物的材料有礦物性纖維、天然纖維或合成纖維，濾料纖維對空氣中的顆粒物進(jìn)行過濾的機(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濾下來；3.攔截作用：顆粒在氣流中處于極靠近濾料的流線上，因顆粒的半徑大于流線與濾料之間的距離而被濾料“刮蹭”而攔截下來；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濾下來；5.靜電作用：如果濾料纖維帶有微弱的靜電，無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濾下來，靜電作用可以幫助過濾材料在不增加氣流阻力的前提下提高過濾效率。一次性無紡布防護(hù)口罩可以在一定程度上預(yù)防流感。佛山鴨嘴型防護(hù)口罩標(biāo)準(zhǔn)</p><p
