How to distinguish the filtration accuracy of filter cloth from the flow of liquid through bag filter cloth? The filtered particles are trapped in the bag, and the working principle of bag filter is pressure filtration. Black single and double fiber filter cloth selects different materials of filter cloth according to the pH value of the sludge. Generally, in order to extend the service life of the filter cloth, polypropylene series filter cloth should be used in an environment with a pH value of 4-8, and nylon series filter cloth should be used in an environment with a pH value of 5-8.5. The selection of filter cloth by industrial filter cloth manufacturers is very important and plays a crucial role in the filtration process. Whether the filter cloth selection is reasonable directly affects the filtration effect and speed. When selecting a specific filter cloth, it should be considered from the basic properties of the filtration slurry and filtration requirements, combined with the permeability (permeability or air permeability), filtration level (maximum and minimum pore size and porosity of the filter cloth), service life (tensile strength and elongation), filter cloth structure and weaving method, chemical properties and cost. The bag filter system mainly consists of three parts: filter container, support basket, and filter cloth. Typically, PE/PP filter cloth filter units are represented in multi precision micrometers (μ m), while the mesh size of nylon mesh and stainless steel mesh filters is based on the accuracy of the unit. The number of holes per square inch (25.4 millimeters per inch) refers to the number of holes, 50 mesh refers to the number of holes per square inch of 50500 mesh is 500, and the higher grid number refers to multiple holes; Except for the hole of the external sieve, it can be used to represent the particle size that decreases with the increase of the mesh size represented by two sieve sizes. As defined above, the diameter related to the yarn is considered to be closely related to the aperture size of the filter cloth woven by monofilament, multifilament, and weaving methods in practical use. At the same time, the performance of the centrifuge speed (centrifugal force), filter material, temperature, etc. are also closely related, making the appropriate selection of the fabric under its operating conditions a complex selection process.
