Easy to clean gray polyester needle felt felt filter bag
Our company insists that the company adheres to the entrepreneurial tenet of “ruling the factory strictly, winning by quality, and winning by new ones”, and has established the spirit of “integrity, cooperation, and service” to require employees. The dust removal bag produced by employees in this spirit is a product. It uses 1-2.5D polyester fine denier yarns and weaves a reinforced base fabric with high-strength low-stretch yarn. The dust-removing cloth bag has the characteristics of high permeability, good air permeability, moderate acid resistance and alkalinity characteristic of ordinary felt filter cloth, and it has very good abrasion resistance, so it is one of the most widely used felt filter materials. Variety. The weight is from 350g / ㎡-800g / ㎡ and the thickness is from 1mm-4mm. Post-treatment methods for dust-removing bags include calendering, scorching, heat setting, dipping and drying, coating, etc. It has the characteristics of stable size, easy cleaning and long service life.
The smoothness of the surface of the filter material has a great influence on the dynamic running resistance of the filter bag of the dust collector. The initial resistance of the filter material is determined by the air permeability of the filter material, and the resistance in operation is many times greater than the initial resistance. The running resistance depends on the smoothness of the surface of the filter material and the dust removal effect. Generally, it is hoped that when the filtering material guarantees the same filtering efficiency, the larger the air permeability, the better, that is, the lower the resistance, the better, because this can save a lot of energy. In bag dust collectors that use airflow to blow back the dust, when using the same pressure and the same air volume for air cleaning, the dust removal effect of the fabric with a large air permeability is better than that with a small air permeability. Weaving. Therefore, under the condition of ensuring that the filter material has a high filtering accuracy, how to improve the permeability of the filter material and the surface smoothness, reduce the dust adhesion, and reduce the running resistance are the first research topics for filter material manufacturers. The surface resinized smooth finishing needled filter felt developed by our factory has a permeability of more than 50% higher than that of ordinary calendering finishing filter, and the surface smoothness is smoother and smoother than calendering finishing. Dust removal bags are widely used in industries such as cement, building materials, mining, metallurgy, grain, and flour.
