Shandong easy cleaning dust bag

Our factory's polyester needle-punched filter felt is made of high-quality polyester fine denier yarn, reinforced base fabric is woven with high-strength and low-elongation yarn, and is made through acupuncture reinforcement and post-processing. In addition to the characteristics of ordinary felt filter cloth, such as high porosity, good air permeability, and moderate acid and alkali resistance, this product also has very good wear resistance, so it is the most commonly used variety among felt filter materials. The weight ranges from /㎡/㎡ and the thickness can be manufactured and processed by our factory. Post-processing methods include calendering, singeing, heat setting, dipping, drying, coating, etc. It has the characteristics of stable size, easy cleaning and long service life.
The surface smoothness of the filter material has a great influence on the dynamic running resistance of the filter material. The initial resistance of the filter material depends on the air permeability of the filter material itself, while the resistance during operation is many times greater than the initial resistance. The running resistance depends on the smoothness of the filter material surface, dust cleaning effect, etc. It is generally hoped that when the filter material has the same filtration efficiency, the greater the air permeability, the better, that is, the lower the resistance, the better, because this can save a lot of energy. In dust collectors that use airflow back-blowing to clean dust, when using airflow with the same pressure and air volume for dust cleaning, the dust cleaning effect is better when using fabrics with large air permeability as the filter bag than using fabrics with small air permeability. Therefore, while ensuring that the filter material reaches a high filtration accuracy, how to improve the air permeability of the filter material, improve the surface smoothness, reduce dust adhesion, and reduce operating resistance are the first topics that filter material manufacturing and processing plants should study. The needle-punched filter felt with resinized surface and smooth finish developed by our factory has a higher air permeability than ordinary calendered filter media, and the surface smoothness is smoother and smoother than that of calendered finish
