A fog trap is a device that uses special materials and structural design to capture and remove fog droplets in the air. Its principle is mainly based on the following two aspects:
Through a specially designed mesh structure, the passing air forms a thin film on the mesh surface, which can effectively prevent the passage of fog droplets. At the same time, this layer of film also has an adsorption effect, which can adsorb the passing droplets on the mesh surface, so as to achieve the effect of trapping the droplets.
Secondly, the special materials used in fog trapping nets usually have good hygroscopicity and hydrophilicity, which can quickly absorb and fix the fog droplets on the mesh surface. The choice of this material is crucial for the fog capture effect, as it can effectively increase the contact area and adsorption force of the fog droplets with the mesh, thereby improving the capture efficiency.
When a certain amount of fog droplets are captured by the fog trap net, the droplets attached to the mesh surface can be removed by regular cleaning or replacement of the mesh surface, so as to restore the performance of the fog trap net. This cleaning or replacement operation can effectively extend the service life and effect of the fog trap net. In short, the principle of fog trapping net is mainly to effectively capture and remove fog droplets in the air through the specially designed network structure and the hygroscopicity and hydrophilicity of the material. The emergence of this technology is of great significance for improving air quality, reducing the impact of haze and improving people's quality of life.
