What is the principle of wind and dust suppression net?

Presumably, those of you who are engaged in construction have a certain understanding of windproof and dust suppression nets. Windproof and dust suppression nets are a very effective technology for controlling dust pollution in open air environments. To produce this product, we need to understand this technology. Therefore, at the beginning, our factory specially consulted professionals to understand the principle of this technology.
Let me explain this technology to you, and if you have anything you want to communicate with us, please feel free to contact us.

The windproof and dust suppression net utilizes the principle of aerodynamics to process windshields with a certain geometric shape according to the results of field environmental wind tunnel experiments. ) when passing through the wall from the outside, the upper and lower interference airflows are formed on the inside of the wall to achieve the effect of strong wind on the outside and weak wind on the wind side; small wind on the outside and no wind on the inside, thereby preventing dust from flying.

In the design of this technology, wind tunnel effect testing was carried out on a variety of windshield and dust suppression panels with different shapes and opening ratios. The results show that the butterfly windshield can significantly reduce the wind speed and wind force under a certain opening ratio. 

Design of the wind and dust suppression wall When the air flow passes through each wind and dust suppression board, the air flow will pass through the openings of the wind protection board. There are two phenomena of separation and attachment behind the windshield. Simultaneously, there are up and down disturbing air flow, which reduces the wind speed of the incoming flow and loses the kinetic energy of the incoming air. At the same time, it avoids the vortex of the air flow in front of the windshield and reduces the turbulence of the incoming air; this reduces the shear stress and pressure on the surface of the material pile, thereby reducing the dust of the material.
The incoming wind passing through the windshield will form turbulent and vortex airflow, but at this time, the wind speed and wind pressure attenuation are relatively large, which is proportional to the wind speed n times. Therefore, the greater the wind speed, the higher the suppression and dust suppression efficiency of the windproof and dust suppression net in the material yard, and the better the effect of controlling dust.

So what are the characteristics of windproof and dust suppression net products?

1. Anti-ultraviolet (aging resistance) - the surface of the product is sprayed, which can absorb the ultraviolet rays in the sun, reduce the oxidation speed of the material itself, make the product have better anti-aging performance, and increase the service life. At the same time, the ultraviolet transmittance is low, which avoids the damage of the windproof and dust suppression net itself in sunlight.

2. Flame retardancy - Windproof and dust suppression nets are generally made of low-carbon steel plates, galvanized sheets and other metal plates, so they have good flame retardancy and can meet the requirements of fire protection and safety production.

3. Impact resistance - the product has high strength and can withstand the impact of hail (strong wind). Under normal circumstances, the windproof and dust suppression nets are set up outdoors, and the outdoor environment is changeable, and there may even be extremely bad weather, so it is necessary to perform an impact strength test. A 1kg steel ball fell freely from a height of 1.5 meters from the top of the wave crest. The results showed that the product had no breaks or through holes.

4. Anti-static - the surface of the product has been treated by electrostatic spraying. After being irradiated by sunlight, it can oxidize and decompose the organic dirt attached to the surface of the product. In addition, its hydrophilicity makes the dust easy to be washed by rain, no need to ask a professional Maintenance by professionals can play a self-cleaning effect.
