创造一个洁净的工作环境是保护工艺设备和操作人员的重要措施,也是现代工业技术生产高质量产品的要求。采用纤维作为空气过滤器的过滤滤料,在世界发达的工业国家早已广泛采用。近几年来,我国有关单位试制用我国生产的无纺布滤料的空气过滤器,特别是在粗效空气过滤器的研究和生产方面已取得了可喜的进展。对中效空气过滤器也进行了试制,但还没有形成系列的定型产品。鉴于 Creating a clean working environment is an important measure to protect process equipment and operators, and it is also a requirement for modern industrial technology to produce high quality products. The use of fibers as filter media for air filters has long been widely adopted in developed industrial countries around the world. In recent years, China’s relevant units have made encouraging progress in the use of non-woven filter air filters produced in China, especially in the research and production of coarse air filters. The intermediate efficiency air filter has also been trial-produced, but a series of stereotyped products have not yet been formed. Given
