The material selection of the bag filter bag is mainly determined by factors such as the usage environment, filtering medium, and filtering requirements of the bag filter. The following are some common bag filter bag materials and their characteristics:
Polypropylene (PP): Polypropylene filter bags have good acid and alkali resistance, corrosion resistance, and high temperature resistance (generally suitable for occasions with temperatures below 90 ° C). It is suitable for filtration applications in general industrial fields and can filter out larger particles.
Polyester (PE): Polyester filter bags have good tensile strength and wear resistance, and can withstand certain mechanical stresses and impacts. It is suitable for liquid filtration and dust removal applications, and can filter out smaller particles.
Nylon (PA): Nylon filter bags have good wear resistance, oil resistance, and acid and alkaline resistance, suitable for liquid filtration applications with high requirements, and can filter out small particles and microorganisms.
Polytetrafluoroethylene (PTFE): PTFE filter bags have excellent temperature resistance, chemical corrosion resistance, and low friction coefficient. It is suitable for applications that require high temperature, corrosive media, or extremely high filtration accuracy.
Stainless steel wire mesh (316L grade): Stainless steel wire mesh filter bags have corrosion resistance, high temperature resistance, and good mechanical strength. It is suitable for filtration applications with special requirements, such as in the food, pharmaceutical, and chemical industries.
When selecting the material of the bag filter bag, it is necessary to comprehensively consider factors such as the nature of the filter medium, temperature, pH value, as well as filtration requirements, process requirements, and budget. It is recommended to consult a professional filter equipment supplier or engineer to select the appropriate filter bag material according to specific needs.
