熔噴布過濾效率加載測試報(bào)告

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，國標(biāo)GB2626-2019中對具體的檢測方法，檢測條件及檢測設(shè)備作了詳細(xì)的要求。今年年初的新冠疫情，導(dǎo)致國內(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試，并會(huì)在文章中附著加載的測試結(jié)果，供大家進(jìn)一步了解和認(rèn)識熔噴布的性能。

什么是熔噴布的加載測試？
熔噴布的加載測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，并記錄剛開始測試和最終結(jié)束時(shí)口罩所對應(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。測試設(shè)備：天氏庫力TSKL-8130 pro顆粒物過濾效率測試儀（雙光度計(jì)），本次測試選用的是油性顆粒，最終加載質(zhì)量為120mg。
