Excuse me: Do you know what FFU dust-free workshop purification membrane is? Let’s learn more about it together.
We all know that clean rooms (CLEANROOM) need to use many filtration equipment when constructing pollution projects, and the core of these filtration equipment are almost all made of FFU dust-free workshop purification membranes , because the filtration precision of this type of PTFE pollution membrane can reach above U15 level (99.9995%), and even reach U17 level (99.999995%), which can fully meet the pollution requirements of high-precision electronic product processing workshops such as semiconductors and chips.
Clean room is also called dust-free workshop, dust-free room or clean room.
It refers to a well-sealed space where air cleanliness, temperature, humidity, pressure, noise and other parameters are controlled according to needs.
The development of clean rooms is closely related to modern industry and cutting-edge technology, because the precision machinery industry (such as gyroscopes, micro bearings, etc. processing), the semiconductor industry (such as large-scale integrated circuit production), etc. must reach a very high dust-free level In order to meet the production requirements, this greatly promotes the development of clean room technology.
Clean rooms are currently widely used in industries such as precision machinery, semiconductors, aerospace, and atomic energy.
FFU dust-free workshop purification membrane is a microporous film produced using polytetrafluoroethylene dispersion resin through special processes such as premixing, extrusion, calendering, and biaxial stretching.
The surface morphology of the microporous film 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.
