Since the human body is the largest source of pollution in a clean room, clean room staff should wear clean work clothes to shield the dust or bacteria they carry to ensure that the room is clean and free from …

For clean rooms in pharmaceutical factories, microorganisms and suspended particles are the main objects of air purification. The most commonly used and most convenient to manage is the use of H14 high-efficien…

Humidity in the semiconductor industry requires semiconductor production plants to maintain a stable environment under year-round climate conditions, especially for temperature, humidity, air cleanliness, air f…

H13 grade high-efficiency filter material is made of glass fiber as the main raw material and adopts wet molding process. It has the characteristics of uniform fiber distribution, large dust holding capacity, l…

The mechanism of surface filtration is the same as that of dust layer filtration, mainly relying on micropore screening. Because the pore size of the membrane is very small, most of the dust particles can be re…

In the 1960s, DuPont first used uniaxial stretching to produce PTFE stretched membranes. Although its micropore size, porosity, and membrane strength were not suitable for use in microfilters, it was widely use…

The development of clean rooms is closely related to modern industry and cutting-edge technology. Since the precision machinery industry (such as gyroscopes, micro bearings, etc. processing), the semiconductor …

When the stretching ratio is small, the length of the microfibers is smaller and the orientation is lower. When the stretching ratio is larger, micropores with a more uniform size distribution can be obtained. …
