What is the performance comparison between PPS filter bag and polyester filter bag?

PPS filter bag and polyester filter bag are two common industrial filter materials, and they have some differences in performance. Next, I will compare the two kinds of filter bags in terms of material properties, heat resistance, chemical resistance, filtration efficiency, service life and price.
First of all, from the perspective of material properties, PPS filter bag is made of polyphenylene sulfide material, which has good rigidity and wear resistance. The polyester filter bag is made of polyester fiber, which has good softness and applicability. Therefore, PPS filter bag is superior to polyester filter bag in terms of wear resistance, while polyester filter bag is more soft and easy to fold, convenient for replacement and cleaning.
Secondly, from the perspective of heat resistance, PPS filter bag has good high temperature resistance and can maintain good performance stability in high temperature environment. In general, the heat-resistant temperature of PPS filter bag can reach about 190 ° C. The heat resistance of polyester filter bag is poor, which can only be used in low temperature environment, and its heat resistance temperature is about 130 ° C. Therefore, in the high temperature environment, the selection of PPS filter bag can better ensure the filtering effect and service life.

Thirdly, from the perspective of chemical resistance, PPS filter bag has good performance in acid, alkali and corrosion resistance, and can maintain good filtering effect in acid and alkali environment. However, polyester filter bags have relatively poor acid, alkali and corrosion resistance, and can not be used in strong acid and alkali environment. Therefore, for the acid-base and corrosive substances that may exist in some chemical processes, the selection of PPS filter bag can better ensure the filtering quality and filter bag life.
Thirdly, from the perspective of filtration efficiency, PPS filter bag and polyester filter bag have good filtration efficiency, which can effectively capture fine particles and particles. In general, their filtering accuracy can reach the level of several microns. Moreover, the filtration efficiency of both can be further improved by adjusting the fiber density and surface treatment process.
Finally, from the perspective of service life and price, PPS filter bag has a longer service life and higher price, while polyester filter bag has a shorter service life and lower price. Therefore, when economic conditions permit, the selection of PPS filter bag can better ensure the filtering quality and service life.
To sum up, there are some differences in performance between PPS filter bag and polyester filter bag. PPS filter bag has good rigidity, heat resistance, chemical resistance and long service life, which is suitable for high temperature and corrosive environment; The polyester filter bag has the characteristics of softness, easy replacement and low cost, which is suitable for filtering requirements under some general process conditions. The selection of filter bag should be based on the specific use environment and filtering requirements.
