PTFE liquid filtration membrane is made of PTFE as raw material. It is biaxially stretched through a special process and utilizes the unique node fibrillarity of polytetrafluoroethylene film, smooth surface, chemical resistance, air permeability and water impermeability, large air permeability, and flame retardant. , high temperature resistance, resistance to strong acid and alkali, non-toxic and other characteristics, the products made have high filtration efficiency, up to 99.99%, close to zero emissions; low operating resistance, fast filtration speed; long service life and can be reused.
The main structure of PTFE liquid filtration membrane: 1. The surface morphology of the filtration membrane is a 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.
It is an asymmetric membrane, and the micropore sizes are different on the front and back sides of the membrane.
?2. The cross-sectional micropore size of the filter 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 there may be one micropore. Connected to multiple channels.
