In recent years, as the purification engineering industry has begun to focus on two-way acceptance standards for product quality and stability, clean room high-efficiency filtration membranes have made outstanding contributions to some high-level purification environments.
For large particle dust based on inertia mechanism, according to traditional theory, when the wind speed is reduced, the probability of dust and fiber collision will be reduced, and the filtration efficiency will be reduced accordingly.
But in practice, this effect is not obvious, because the wind speed is smaller, the fiber’s rebound force against dust is also smaller, and dust is easier to stick.
The higher the wind speed, the greater the resistance.
If the service life of the filter is based on the final resistance and the wind speed is high, the service life of the filter will be short.
It is difficult for ordinary users to actually observe the impact of wind speed on filtration efficiency, but it is much easier to observe the impact of wind speed on resistance.
The porosity of the clean room high-efficiency filtration membrane can reach more than 88% or even higher, and this membrane has 1.4 billion micropores per square centimeter, with a pore size range of 0.1um-0.5um, and has high and low temperature resistance ( -200℃-260℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
It can ensure complete retention of bacteria and other impurities while having a large flux.
