Traditional HEPA high-efficiency filter paper mainly relies on the adsorption of fibers to “stick” particles. The diameter of the fiber is about the same as that of the particles, and the “mesh” gaps between each fiber are larger. The “wide” space between the fibers allows airflow to pass smoothly. However, due to the layer-by-layer arrangement, small particles will inevitably hit one of the messy and intertwined fibers and be adsorbed. At this microscopic scale, the intermolecular force between fibers and dust particles is enough to overcome the influence of airflow and “adhere” the two together to achieve the purpose of intercepting particulate matter.
So over time, the gaps between the fibers of HEPA high-efficiency filter paper will become larger and larger. It gets smaller and smaller, and some gaps will disappear. Although the filtration efficiency of the filter will not decrease, the wind resistance of the filter will increase. As a result, the air volume will decrease, and the noise will increase, causing the HEPA filter to need to be replaced regularly.
HEPA high-efficiency filter paper As the mainstream filter material on the market, the material has good temperature resistance and corrosion resistance, and has a wide range of chemical applications sex. The composite method adopts two methods: glue composite and thermal composite. It has strong moisture resistance and hydrophobicity, and can be washed or pulsed backflushed to remove surface dust for repeated use.
