Foam air filter material
Foams generally have three-dimensional connected pore structure, large thickness, low volume density and other structural characteristics, and have excellent resilience and machinability. They have been used in various air filtration situations such as air purifiers, automobile exhaust treatment, industrial dust removal, Ceramic Foam Filtration Slice, etc. Typical foam air filtration materials include polyurethane foam, metal foam and ceramic foam. In addition to their basic filtration properties, these materials have a variety of specialized applications such as flame retardation, sound absorption, elevated temperature resistance, and corrosion resistance. However, the internal pore size of such materials is normally large, which makes it difficult to achieve superior filtration accuracy and does not effectively trap fine particles. Foam air filter materials are commonly used as skeleton materials for air filters, or to cut large particles in the coarse filtration process to extend the service life of fine filter materials.
Air filter material type 1
Particulate air filtration material
According to the principle of air filtration, any medium accumulated to a certain density can cut off the particles in the air flow, so as to achieve gas-solid separation. Therefore, the filter cake formed during the dense packing process can be used as an air filtration material even if the filter medium is granular. Granular filter material mainly includes activated carbon, diatomite, quartz sand, slag, etc., with wide sources and low cost. However, these materials need to be tightly packed to achieve effective filtration of fine particles. This method will bring great pressure resistance, which makes it impossible to achieve elevated throughput filtration of dusty airflow. The particle filter material is mainly used in combination with other filter materials, which can not only improve the filtration performance of the matrix material, but also achieve multifunctional filtration.
