熔噴布過濾效率加載測(cè)試報(bào)告

返回列表來源：天氏庫力 發(fā)布日期 2020-12-31 瀏覽：

熔噴布的過濾效率指的是熔噴布在特定的面積上，特定的氣流量下，能夠過濾細(xì)小顆粒的能力，國(guó)標(biāo)GB2626-2019中對(duì)具體的檢測(cè)方法，檢測(cè)條件及檢測(cè)設(shè)備作了詳細(xì)的要求。今年年初的新冠疫情，導(dǎo)致國(guó)內(nèi)口罩緊缺，同樣緊缺的是口罩的核心心臟-熔噴布。作為口罩過濾性能的關(guān)鍵部位，必須質(zhì)量嚴(yán)格達(dá)到標(biāo)準(zhǔn)才能被用到口罩上，否則會(huì)嚴(yán)重威脅大家的生命安全。

我們都知道口罩分：一次性醫(yī)用口罩，醫(yī)用防護(hù)口罩，一次性民用口罩，N95口罩以及一些防塵防霾口罩，除了用途和材料結(jié)構(gòu)上的區(qū)別，他們最根本的區(qū)別在于過濾效率和氣流阻力上，而一只口罩的過濾效率與氣流阻力的大小幾乎取決于熔噴布，本文我們主要給大家展示一下熔噴布的加載測(cè)試，并會(huì)在文章中附著加載的測(cè)試結(jié)果，供大家進(jìn)一步了解和認(rèn)識(shí)熔噴布的性能。

什么是熔噴布的加載測(cè)試？
熔噴布的加載測(cè)試一般是指在特定溫度和特定的上游顆粒物濃度范圍內(nèi)，持續(xù)對(duì)口罩的外表面釋放顆粒物，直至口罩外表面的顆粒物重量達(dá)到一定的克重，并記錄剛開始測(cè)試和最終結(jié)束時(shí)口罩所對(duì)應(yīng)的過濾效率和氣流阻力。詳細(xì)的可以參考如下的視頻和數(shù)據(jù)結(jié)果，結(jié)果僅供參考。測(cè)試設(shè)備：天氏庫力TSKL-8130 pro顆粒物過濾效率測(cè)試儀（雙光度計(jì)），本次測(cè)試選用的是油性顆粒，最終加載質(zhì)量為120mg。
