With the advancement of technology, the dust cleaning technology and bag filter technology of bag dust collectors have been rapidly developed and improved. Therefore, the filtration efficiency, service life, and requirements for PTFE filter membranes are becoming higher and higher, which leads to the Advances in filtration technology of high-efficiency filter paper.
When filtering polydispersed phase particles, both theoretical analysis and actual measurement results show that as the diameter of the particles increases from small to large, the overall filtration efficiency changes firstly and then increases.
The reason is that various capture mechanisms have different effects on particles of different particle sizes.
Smaller particles are deposited due to diffusion, while larger particles are captured under the action of interception and inertia. When the particle size increases from small to large, the diffusion efficiency gradually weakens, and the inertia and interception efficiency gradually increase. This This leads to a weakening of the overall collection efficiency in the small particle size range.
PTFE high-efficiency filter paper refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and processed by calendering, extrusion, and biaxial stretching.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, there are up to hundreds of millions of micropores per square centimeter, and the filtration level can reach H13 -U16, can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
