以下的呼吸性粉塵的阻塵效率為標(biāo)準(zhǔn)的。一般的紗布防塵面具，其阻塵原理是機(jī)械式過(guò)濾，也就是當(dāng)粉塵沖撞到紗布時(shí)，經(jīng)過(guò)一層層的阻隔，將一些大顆粒粉塵阻隔在紗布中。但是，微細(xì)粉塵尤其是小于5 μm 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)。市場(chǎng)上有一些防塵面具出售，其濾料由充上長(zhǎng)久靜電的纖維組成，那些小于5 μm 的呼吸性粉塵在穿過(guò)這種濾料的過(guò)程中，就會(huì)被靜電吸引而吸附在濾料上，真正起到阻塵作用。第二：防塵面具與臉形的密合程度要好。當(dāng)防塵面具與人臉不密合時(shí)，空氣中的粉塵就會(huì)從防塵面具四周的縫隙處進(jìn)入呼吸道。所以，人們應(yīng)選用適合自己臉形的防塵面具并正確佩帶防塵面具。第三：佩戴要舒適，包括呼吸阻力要小，重量要輕，佩戴衛(wèi)生，保養(yǎng)方便，如佩戴拱形防塵面具。PM2.5防塵面具可以是掛耳式、綁帶式、頭戴式，其中掛耳式從使用上更為方便舒適。普通防塵面具</p><p

1.防護(hù)口罩不僅能及時(shí)隔離細(xì)菌，空氣中的灰塵，霧霾，而且能更好的保護(hù)呼吸道，和面部皮膚。 2.可以保護(hù)面部皮膚，愛(ài)美的女生可以帶個(gè)大點(diǎn)的防護(hù)口罩把脖子一塊保護(hù)起來(lái)，更年輕。 3.有口腔疾病的人戴上防護(hù)口罩可以更好地保護(hù)呼吸道，有鼻炎的的人盡量少帶防護(hù)口罩。 4.戴上防護(hù)口罩能及時(shí)隔離空氣中的病菌，能更好保護(hù)自身免疫系統(tǒng)，較好帶PM2.5的防護(hù)口罩。 5.噴漆的人要選擇的防護(hù)口罩是3M防護(hù)口罩，內(nèi)置活性炭，可以有效隔離甲醛和金屬元素。學(xué)生防塵面具怎么戴</p><p
