First, its stainless steel surface is often specially treated. Through a fine micro-etching process, an extremely small and evenly distributed microporous structure is formed on the surface of the stainless steel. The pore size of these micropores is precisely controlled to effectively block dust particles in the air, and its filtration accuracy can reach the micron level or even smaller. For example, for common fine pollutants such as PM2.5, these micropores are like fine sieves, intercepting them outside the purification panel to prevent them from entering the purification space, thereby ensuring the cleanliness of indoor air.
Secondly, inside the interlayer, the purification panel is usually equipped with high-efficiency filter materials. Like high-quality glass fiber filter paper or melt-blown non-woven fabrics, these materials have a large specific surface area and rich fiber structure. When the air passes through the interlayer, the tiny particles will be adsorbed and captured by the fibers, greatly improving the filtration efficiency of suspended particles in the air. Moreover, these filter materials also have a certain electrostatic adsorption capacity, which can further enhance the adsorption effect of microorganisms such as bacteria and viruses and some harmful gas molecules, and improve the quality of air purification from many aspects.
Furthermore, the edge sealing design of the purification panel is also a key link in its air filtration. A special sealing strip or sealing process is used to ensure that the purification panel is tightly closed around to prevent unfiltered air from penetrating from the edge gap. This tight edge sealing cooperates with the surface micropores and sandwich filter materials to form a complete air filtration system, allowing the purification panel to maintain efficient filtration performance throughout the use process.
In addition, some handmade stainless steel sandwich purification panels will also add functional substances such as photocatalyst coatings on the surface. Under light conditions, photocatalysts can decompose harmful organic gases in the air, such as formaldehyde and benzene, and convert them into harmless water and carbon dioxide. This not only improves the purification ability of the purification panel for gaseous pollutants, but also enables the purification panel to have the functions of self-cleaning and long-term purification, further optimizing the indoor air environment. In short, the handmade stainless steel sandwich purification panel provides a comprehensive, efficient and lasting solution for air filtration through its unique design of surface micropores, sandwich filter materials, edge sealing and functional coating, meeting the needs of many places with high requirements for air purification.
