¿Cuál es la estructura y selección de materiales de los filtros de aire de alta eficiencia?

Estructura: El marco exterior delfiltro de aire de alta eficienciaUtiliza principalmente perfiles de aleación de aluminio, marcos de placas multicapa, marcos de placas de aluminio y marcos de placas de acero galvanizado. Los marcos de perfiles de aleación de aluminio más utilizados se fabrican principalmente en estructuras de forma cuadrada.

Material filtrante: el material filtrante defiltro de aire de alta eficienciaEs principalmente fibra de vidrio y gradualmente se utiliza fibra química. Algunos fabricantes extranjeros utilizan fibra estática de politetrafluoroetileno (Electret) para fabricar filtros de alta eficiencia, comúnmente conocida como PTFE.

La estructura defiltros de aire de alta eficiencia can be divided into two types: without partitions and with partitions. The non partition mainly uses hot melt adhesive as the separator for the filter element, which is convenient for mechanized production. In addition, it has the advantages of small size, light weight, easy installation, stable efficiency, and uniform wind speed. The large batch of filters required for clean factories mostly adopt a non partition structure. There is a partition board for high efficiency. Aluminum foil and paper are mostly used as folded filter separators to form an air passage. High quality Kraft paper, hot roll forming or offset paper is used as the separator. The Coated paper with double-sided adhesive is often used as the partition board, which is mainly aimed to prevent the partition board from shrinking due to the influence of cold, hot, dry and wet, thus emitting particles. However, when there is a change in temperature and humidity, this type of partition paper may have larger particles emitting, resulting in unqualified cleanliness testing in the clean workshop. Therefore, for places with high cleanliness requirements, customers should be recommended to use non partition high-efficiency air filters. The price of filters with partitions abroad is higher than that without partitions, so there are fewer places in foreign countries where partitions are used. In addition, compared to rectangular channels with partition filters, V-shaped channels without partition filters further improve the uniformity of dust collection and extend their service life. Non partition filters for ventilation can avoid the use of metal components and are easy to dispose of, meeting increasingly strict environmental requirements. Except for certain special occasions with high temperature resistance and high safety requirements, filters without partitions can replace filters with partitions.
