Sub-high efficiency air filter plays an important role in the field of air purification. Optimizing its filter material structure and fiber arrangement is the key to improving performance.
In terms of filter material structure, a multi-layer composite design can be adopted. Fiber layers of different thicknesses and materials are combined to form a gradient filtration structure. The coarser fiber layer first intercepts larger particles, reducing the burden of the subsequent fine fiber layer; the fine fiber layer is responsible for capturing smaller particles, thereby improving the overall filtration efficiency.
For fiber arrangement, the use of a disordered staggered method can increase the probability of collision between particles and fibers and improve the interception effect. By adjusting the density distribution of fibers, the airflow resistance can be reduced while ensuring the filtration efficiency.
Selecting fiber materials with good electrostatic adsorption properties is also an optimization method. Electrostatic action can enhance the adsorption capacity of tiny particles, improve filtration efficiency, and reduce dependence on fiber density, thereby reducing resistance.
It is also important to optimize the diameter and length of the fiber. Finer fibers can capture tiny particles more effectively, but too fine may lead to increased resistance. Therefore, it is necessary to find a suitable balance point that can improve the filtration efficiency without excessively increasing the resistance.
In the manufacturing process of the filter material, controlling the fiber molding process to make it have a more uniform distribution and better consistency can help improve the overall performance of the filter. In addition, surface treatment of the filter material to increase its surface roughness or hydrophilicity can enhance the adsorption and retention capacity of particulate matter and further improve the filtration efficiency.
To extend the service life, antibacterial and anti-corrosion components can be added to the filter material to reduce the growth of microorganisms and the damage of chemicals to the filter material. At the same time, combined with advanced simulation technologies such as computational fluid dynamics (CFD), numerical simulation and optimization of the filter material structure and fiber arrangement can predict and improve the design before actual production.
In short, by comprehensively considering the multi-layer composite design of the filter material structure, the disordered staggered arrangement of the fibers, the electrostatic adsorption performance, the optimization of the diameter and length, the surface treatment, and the addition of protective components, and with the help of simulation technology, the filter material structure and fiber arrangement of the sub-high efficiency air filter can be effectively optimized to achieve the goals of improving filtration efficiency, reducing resistance and extending service life, providing a strong guarantee for providing a cleaner air environment.
