摘要
文章系统介绍并对比了国内外医用防护口罩和颗粒物防护口罩标准及其技术指标,分析了过滤效率、密合性、呼吸阻力等核心指标技术要求的特点和差异,以及不同技术指标对口罩防护效果和适用场景的影响。在此基础上,对不同类型的口罩进行防护等级分类,并提出合理的选用建议,为促进防护口罩的规范化研发、生产和销售提供理论指导。
In order to make a comprehensive and clear understanding of the various types of respirators protective effect and its standards,strictly follow the relevant national standards for product development,the national standards and technical indicators of domestic and foreign medical protective masks and particulate protective masks were introduced and compared.The characteristics and differences of core technical requirements such as filtration efficiency,tightness and respiratory resistance,as well as the impact of different technical indicators on the protective effect and application environment of masks were analyzed.On this basis,different types of masks were classified in terms of protection levels,and reasonable selection suggestions were put forward,which provides theoretical guidance for promoting standardized research and development,production and sales of protective masks.
