What is the production process of ptfe flat membrane manufacturers?

The production process of the ptfe flat membrane manufacturer is to fully mix the dry PTFE fine powder with additives and then enter the extruder. The powder is pushed and extruded into strips of PTFE, as shown in Figure 1, and then rolled It is rolled into a film sheet under the machine. After heating to evaporate the additives, it can be stretched longitudinally and transversely, and then through heat treatment, shaping, cutting and winding to obtain a biaxially stretched microfiltration membrane. The biaxial stretching process makes the film have good void characteristics. After the film in different directions is stretched, the structure of the film’s micropores and agglomerates changes, and at the same time, the mechanical properties of the film have anisotropic characteristics.

The company has a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
