Ten inspection methods for dust removal bags

1、 Thickness: Thickness is one of the important physical properties of dust removal bags, and high-temperature filter bags have a significant impact on the permeability, wear resistance, and other properties of the filter material.

2、 Density: The density of a dust removal bag is expressed in terms of the number of yarns per unit distance, that is, the number of warp and weft yarns between Lin (2.54cm) or 5cm. The density of the dust removal bag manufacturer and the non-woven fabric is calculated based on the volume density, which is the weight drop per unit area of the filter material in thickness (in grams per square meter).

3、 Quality: Quality is generally referred to as cloth weight, which refers to the weight of the dust removal filter material per square meter. As the material and structure of the dust removal bag are most intuitively reflected in its quality, quality becomes the most basic and important indicator determining the performance of the dust removal bag, and also an important factor determining the price of the dust removal bag.

4、 Moisture absorption: The moisture absorption of dust removal bags is one of the indicators for evaluating their performance. Especially when in dusty gases

This performance becomes even more important when it contains a certain amount of moisture. Because when the moisture content of the dust containing gas is high and the hygroscopicity of the dust removal bag is high, it can cause dust adhesion, block the dust removal bag, increase resistance, and ultimately lead to a deterioration of the dust removal performance. At present, Jiuzheng Tongming already has non hygroscopic filter materials that are not afraid of condensation and have good performance.

5、 Flame resistance: The flame resistance of dust removal bags is an important safety indicator in their actual use. The combustion of dust removal bags includes several processes, including melting oxidation and cracking of polymers. Polymers are often classified into four categories based on their own characteristics and their ease of combustion, namely flammable, combustible, refractory, and non combustible. Refractory and non combustible filter materials can improve the safety of dust collector operation.

6、 Temperature resistance and heat resistance: Moisture resistance and heat resistance refer to the degree to which the dust removal bag can withstand temperature and heat, which is an important factor in selecting the dust removal bag filter material. When selecting dust removal bag filter materials, not only should the temperature resistance of the dust removal bag filter material be considered, that is, the long-term working temperature and short-term possible high temperature and humidity of the dust removal bag, but also the heat resistance of the dust removal bag should be considered. The ability of the filter material to withstand dry heat and damp heat. After treatment, the temperature resistance of the dust removal bag will be improved.
