PPS filter bag is a high-energy filter material, which is widely used in various industrial fields, such as chemical, petroleum, metallurgy, electric power, etc. PPS filter bag has excellent high temperature resistance, corrosion resistance, wear resistance, high strength and other properties, so it can still maintain a good filtration effect in high temperature, high pressure and high corrosion environment.
The resistance coefficient of PPS filter bag is one of the important parameters to measure its filtration energy. The drag coefficient is the ratio of the resistance experienced by the gas as it passes through the filter bag to the gas flow velocity. The lower the resistance coefficient, the better the air permeability of the filter bag and the better the filtration effect. The resistance coefficient of PPS filter bags is usually 10-2.0, the specific value depends on the material, thickness, structure and other factors of the filter bag.
The specification table of PPS filter bag mainly includes the following aspects:
Size: The size of the PPS filter bag is usually expressed in diameter and length, such as 130 2450mm, 160 3500mm, etc. Different sizes of filter bags are suitable for different filtration equipment and working conditions.
2.Thickness: The thickness of the PPS filter bag is usually measured in millimeters, such as 10mm、1.5mm、2.0mm, etc. The greater the thickness, the stronger the filter bag will be, but the breathability may be reduced. When selecting filter bags, it is necessary to consider comprehensively according to the actual working conditions and equipment requirements.
3.Material: The main material of PPS filter bag is polyphenylene sulfide (PPS), which has good high temperature resistance, corrosion resistance, wear resistance and other properties. In addition, PPS filter bags can also be compounded with other materials such as glass fiber, stainless steel wire, etc., to improve the energy and application range of the filter bags.
4.Structure: The structure of PPS filter bag mainly includes plain weave, twill, satin pattern, etc. Filter bags with different structures have differences in air permeability and filtration accuracy, so it is necessary to select the appropriate structure according to the actual working conditions and equipment requirements.
5.Surface treatment: In order to improve the filtration effect and service life of PPS filter bags, surface treatment can be carried out on the filter bags, such as coating, laminating, etc. The surface treated filter bag has better performance in terms of corrosion resistance, wear resistance, and improvement of filtration accuracy.
6.Other parameters: Other parameters of PPS filter bags also include air permeability, breaking strength, elongation, etc. These parameters can help users to have a more comprehensive understanding of the capacity and scope of application of the filter bag.
PPS filter bags have excellent performance and a wide range of application prospects. When selecting and using PPS filter bags, it is necessary to comprehensively consider the size, thickness, material, structure and other parameters of the filter bags according to the actual working conditions and equipment requirements to ensure the use effect and service life of the filter bags.
