Title
(EN) Filtering (ventilating) system of breathing mask and/or clothing
(ZH) 口罩及/或衣服过滤(透气)系统
Abstract
(EN) The invention discloses a mouthpiece and/or cloth filtering (poromeric) system in the nanometer mouthpiece and cloth and filtering technical domain, which is characterized by the following: using raw material with dog, activated char, non-fabric and so on; killing SARS virus and other minor bacteria; obtaining nanometer filter material with grain size at 1-5000nm; simplifying the structure of filter system; displaying good permeability to air and good filtering effect.

本发明涉及一种口罩及/或衣服过滤(透气)系统,属于纳米口罩及衣服和过滤技术领域。目前口罩及/或衣服过滤系统种类很多,使用材料包含布头,活性炭,不织布等等,但是现在口罩存在制造困难,效果不好,无法满足部分要求如SARS病毒及其他较小细菌,随着纳米技术的进步研究人员获得纳米过滤材料(片,膜片,卷),纳米孔的大小1-5000纳米可以进行调整。为解决现有口罩制造困难,过滤速度慢,制造难的缺点,本发明在口罩及/或衣服安装多孔径纳米过滤材料(片,膜片,卷),本发明具有过滤系统结构简单,过滤颗粒小(细菌,病毒都可以使用),透气好,过滤效果好的优点。
