What are the common cutting methods for dust removal filter cloth? There are three cutting methods for common dust removal cloth. Sffiltech will tell you

1. No edge sealing (cold cutting): it is mainly cut directly by electric scissors. This cutting method is simple to produce wool chips, and cleaning treatment is not allowed after cutting. There will be a lot of cloth chips on the edge in the scrubbing process, which has no cleanliness, so it is generally not recommended to use.

2. Laser cutting: through the instantaneous high-temperature melting of the laser, the edge sealing is better and there will be no hair scraps. After cutting, it can be cleaned by net spraying and cleaning, so as to make the product reach a high dust-free standard. The defect is that the edge will be slightly hard because it is melted. Pay attention to the scrubbing process. 75% of shopping malls use this edge sealing method.

3. Ultrasonic edge banding: through the vibration generated by the ultrasonic vibration unit (vibrator) (converting electric energy into mechanical energy), heat is transferred through horn (welding head), and then the fabric is extruded and broken by the cutter. This edge banding is a perfect method of cutting clean cloth at present. The edge banding effect is good and the edge will not be hard, but the cost of this cutting method is too high, The market share is about 15%.

Influence factors of dust removal bag selection on flue gas emission: influence of dust removal bag selection on flue gas emission: different types of filter materials have different filtration accuracy. Generally speaking, the filtration accuracy of glass fiber filter material is as follows: flat width < needle felt filter material < expanded yarn filter material < membrane filter material; Impact of ash removal method on flue gas emission: under the same conditions, the higher the ash removal pressure, the greater the impact on dust emission; Impact of dust content in flue gas on flue gas emission: under the same conditions, the higher the ash removal pressure, the greater the impact on dust emission; Influence of dust removal equipment manufacturing process on flue gas emission: the manufacturing level, sealing performance, welding level and pipeline sealing of dust removal equipment directly affect the flue gas emission concentration.
