預(yù)約設(shè)計(jì)

一“罩”難求，這些你都知道嗎？

2020-02-23 19957

2020年春節(jié)，一個(gè)不平常的春節(jié)。

一夜之間，“干咳、37.3℃、新型肺炎”讓人聞之色變，“四川加油、武漢加油、中國加油”成了你我心里共同的聲音；而“外科醫(yī)用口罩、N95口罩”成了全民囤積的緊缺物資。大家在社區(qū)藥店、各大藥房、京東天貓、朋友圈各個(gè)渠道，都在積極囤貨。

一周時(shí)間，一罩難求，可關(guān)于“罩”的這些你都知道嗎？

1.口罩的分類識(shí)別

N系列：防護(hù)非油性懸浮顆粒無時(shí)限

R系列：防護(hù)非油性懸浮顆粒及汗油性懸浮顆粒時(shí)限八小時(shí)

P系列：防護(hù)非油性懸浮顆粒及汗油性懸浮顆粒無時(shí)限

以上每系列又劃分出了3個(gè)水平：95%，99%，99.97%(即簡稱為95，99，100)，所以共有9小類濾料。

那么你現(xiàn)在買到的是什么防護(hù)級(jí)別的口罩呢？

2.如果買不到N95或者醫(yī)用外科口罩怎么辦？

如果買不到N95或外科醫(yī)用口罩也不必過于著急，把你的口罩反過來，如果口罩能兜住水，這樣的口罩對(duì)于飛沫也是有一定防護(hù)作用的。

還切記一點(diǎn)，少出門或不出門，好好宅家。

3.網(wǎng)傳口罩的消毒方法效果如何？

噴酒精?

醫(yī)用外科口罩和醫(yī)用N95口罩外表面都經(jīng)過“拒水處理”，在表面噴酒精很難起到對(duì)內(nèi)部的消毒左右。酒精還會(huì)破壞口罩外層的防水結(jié)構(gòu)，加速口罩過濾層的失效。

消毒劑浸泡？

如果用消毒劑浸泡，可能會(huì)有消毒成分殘留的問題，對(duì)于人體健康還是有一定的潛在危險(xiǎn)。

微波爐、蒸鍋、沸水加熱？

水的進(jìn)入會(huì)是口罩中過濾層的電荷迅速消失，過濾效果大幅下降。同時(shí)，聚丙烯熔噴材料不耐高溫，溫度大于80℃會(huì)收縮變形。

4.口罩應(yīng)該如何存放？

非常時(shí)期，在外注意口罩防護(hù)，在家也要注意每天必要的開窗通風(fēng)；

如果你還擔(dān)心家里的空氣不干凈，可以把空清打開，且注意空清濾網(wǎng)的清洗和更換。
