熔喷聚丙烯驻极体过滤材料由于具有特殊的静电过滤机理,而显现出低流阻、高效率等优点,尤其是所具有的除尘、灭茵多功能的特点,使其成为了。医用防护口罩的最佳用材。在特殊环境下的驻极体电荷稳定性是需要深入了解的关键问题。本文在前期工作的基础上,采用浸泡方法研究了材料在医用消毒剂作用下的过滤效率稳定性。结果表明:经双氧水、苯酚、戊二醛、含氯消毒剂、硼酸、甲醛、过氧乙酸和消毒酒精等医用消毒剂浸泡后,其过滤效率几乎不会衰减。但材料用洗洁精和洗衣粉清洗时,其过滤性能下降较大。因此,熔喷聚丙烯驻极体过滤材料在医用环境中使用具备良好的稳定性,可作为医用防护口罩的首选材料。但建议作为一次性呼吸防护用品使用。
鎔噴聚丙烯駐極體過濾材料由于具有特殊的靜電過濾機理,而顯現齣低流阻、高效率等優點,尤其是所具有的除塵、滅茵多功能的特點,使其成為瞭。醫用防護口罩的最佳用材。在特殊環境下的駐極體電荷穩定性是需要深入瞭解的關鍵問題。本文在前期工作的基礎上,採用浸泡方法研究瞭材料在醫用消毒劑作用下的過濾效率穩定性。結果錶明:經雙氧水、苯酚、戊二醛、含氯消毒劑、硼痠、甲醛、過氧乙痠和消毒酒精等醫用消毒劑浸泡後,其過濾效率幾乎不會衰減。但材料用洗潔精和洗衣粉清洗時,其過濾性能下降較大。因此,鎔噴聚丙烯駐極體過濾材料在醫用環境中使用具備良好的穩定性,可作為醫用防護口罩的首選材料。但建議作為一次性呼吸防護用品使用。

It was known that melt-blown polypmpylene electret nonwoven was the best materials used as facepiece respirators. It had advantages of higher filtration effcieney, lower pressure drop and germicidal function because of its special electrostatic faltering mechanism. The charge stability of electret under special environment is the key problem needed to study. In this paper, the stability of fdtration efficiency was investigated when the melt-blown polypropylene electret nonwoven was soaked in disinfector solution. The results showed that the filtration effciency declined little after soaked for 24 hours in hydrogen peroxide, phenol, glutaraldehyde, chlorine-containing disinfectant, boracic acid, formaldehyde, pemxyacetic acid and rubbing alcohol. However, the filtration efficiency displayed a marked decay when it was soaked in washing-up liquid and detergent powder. It could be come to a conclusion that melt-blown polypmpylene electret nonwoven was a kind of favorable facepiece respirator materials when used in medicine environment, however, it was proposed as a disposable respiratory protection production.
