Dust bag
Details
The polyester dust bag is the main filter material in the bag filter. It adopts a non-woven needle punching process. The polyester staple fiber is carded and laid on a fine fiber cloth with staggered fibers and uniform gap distribution, and then needle punched into a felt. This filter material has high strength, strong elastic recovery, stable fabric size, good performance, large porosity, good air permeability, long service life, good dust removal effect, and has mechanical properties and properties at room temperature (below 130°C). Because polyester is cheap, polyester needle felt dust bag is a cost-effective filter medium at low temperatures.
According to the characteristics of the dust of different manufacturers, the polyester dust bag bag often has treatment methods such as mixing fiber, singeing, calendering, dipping, etc. The polyester needle felt made of polyester has added easy cleaning (fast dust peeling), (Anti-condensation) and performance, forming a series of products.
The polyester dust bag is made of fine-denier and large chemical fiber yarns of good quality. The polyester dust bag is produced by equipment, which can evenly and quantitatively mix a variety of fibers, and then use multiple mixing cotton units to facilitate the layering and compounding of different fibers between the fiber webs. Gradient transformation.
In addition to the advantages of high porosity, good air permeability, dust collection, and long service life, the polyester dust bag has a moderate temperature resistance level, which can reach 150 ℃ in an instant. Besides the characteristics of moderate acid and alkali resistance, it also has very good characteristics. Therefore, it is one of the most used varieties of felt filter materials.
The polyester dust bag can be taken out and cleaned repeatedly, so it is more economical. Each filament is made by twisting many thin filaments of the same diameter together, and then woven and formed into a mesh according to the warp and weft density. When filtering particles with a diameter larger than the mesh number, the filter cloth can trap them on the surface, and the particles with a diameter smaller than the mesh number pass through the mesh and enter the downstream. Therefore, the screen filter bag achieves surface filtration, and the smooth surface is also easy to clean.
