Coated filter media is a microporous membrane made of dispersed polytetrafluoroethylene resin and various substrates.
The main feature of this filter material is surface filtration, which can improve filtration efficiency and improve the problems of increasing filtration pressure and high concentration of fine dust emissions that often occur in traditional filtration methods.
The PTFE membrane has a three-dimensional mesh structure with no through holes.
The porosity and pore size distribution are important indicators for measuring PTFE membranes.
The porosity of PTFE membrane is generally between 80% and 95%.
High porosity will increase ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
With special production technology, different pore sizes can be controlled for different materials to achieve high-efficiency filtration.
Usually, membrane thickness is not an indicator for evaluating PTFE membranes. If the thickness of the membrane is too thick, it will easily cause problems such as low air permeability and high operating pressure.
According to years of research and observation, film thickness basically does not affect the service life. The key is the composite strength, which is an important factor affecting the service life.
