PTFE ultrafiltration membrane is an environmentally friendly material. It is made of polytetrafluoroethylene (PTFE) material through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.
This material has excellent high temperature resistance, high temperature resistance, low temperature resistance, alkali resistance, anti-aging, anti-oxidation, electrically insulated wire, hydrophobicity, non-toxicity, high lubrication, non-adhesion, weather resistance, and chemical resistance quality and many other features.
Therefore, it is widely used in air filtration, aviation, electronics, electrical appliances, chemicals, machinery, construction, textiles, medicine and many other fields.
The main structure of ptfe ultrafiltration membrane: 1. The surface morphology of ptfe ultrafiltration 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 ptfe ultrafiltration 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.
