As the filtration process proceeds, filter cake filtration begins, the thickness of the mud cake gradually increases, and the filtration resistance increases. The longer the filtration time, the higher the separation efficiency. The specially designed polytetrafluoroethylene plate and frame filter membrane filter cloth can intercept particles with a particle size less than 1 μm. In addition to the excellent separation effect and high solid content of the mud cake, the filter press can also provide a further separation process: during the filtration process, the filter mud cake can be washed well at the same time, so that valuable substances can be obtained Recover and obtain high purity filter mud cake.
PTFE frame filter membraneThe surface morphology is Spider web-like microporous structure. Pores are formed between the microfibers, and the arrangement direction of the microfibers is basically parallel to the stretching direction; the junction of the fiber bundles is the node, which is formed by the entanglement of many microfibers. PTFE membrane is an asymmetric membrane, and the micropore size is different on the front and back sides of the membrane. The cross-sectional micropore size of the membrane is larger than the micropore size on its surface, and the vertical and horizontal micropore sizes are also different, with the longitudinal micropores being larger than the transverse ones. The cross-section of the membrane is a network structure. The three-dimensional structure of the pores has very complex changes such as network connectivity, pore nesting, and channel bending. There may be multiple micropores forming a channel, or one micropore may be connected to multiple Channels are connected.
The currently independently developed polytetrafluoroethylene plate and frame filter membrane is the core filter material of the air filter and is highly hydrophobic. With the characteristics of chemical resistance, hydrophobicity and low wind resistance, air filters produced using our ptfe plate and frame filter membrane can achieve high dust removal efficiency. For some extremely small particles with a diameter of 0.1um-0.3um, the filtration level is Can reach H13-U16. If you are interested, please enter the store for consultation.
