Learn About Common Filter Bag Finishes Such as Calendering (Glazing), Singeing, Napping, and Coating.
There are a few different finishes and treatments that can help lengthen the life of your filter bag, improve its stability, and make cleaning an easier process. Filter performance is directly related to how well filters can tolerate the work environment it’s in. So applying a specific finish or treatment is one way to achieve better performance.
Fabrics for filters are usually made of woven felts, non-woven felts, natural fibers, synthetics, or polyphenylene sulfide. Natural fabrics, such as wool and cotton, are usually preshrunk to eliminate bag shrinkage during operations. Certain fabrics can be treated with silicone to give them better cake release proprieties. When it comes to both synthetic and natural fabrics, processes such as calendering (glazing), napping, singeing, or coating are typically applied.
How to choose the filter bag ?
The filter bag plays a key role in the dust-cleaning process, so it is very important to do the filter selection, which should be based on its performance and the nature of the smoke, so as to have a rational and optimized scheme.
The Factors that affecting the selection of the filter medium
The Select Indication of the Filter medium
A. Temperature
B. Chemical Property
C. Concentration of the dust content
D. Filter Gas Speed
