Application Scenarios

　　Dustproof network has a wide range of applications. It is not only suitable for coal storage plants in coal mines, coking plants, power plants and other enterprises, but also for wind and dust prevention, but also for coal storage plants in ports and terminals and various material yards.In addition, the open-air materials yards for enterprises such as steel, building materials, and cement are also the stage for them to show their strengths.In harsh environments, such as crop windproofing, sandy weather dustproofing, etc., dustproof nets can also play their role.At the same time, it is also widely used in railways, highway coal storage yards, construction sites, road dust and both sides of highways.The dust suppression effect of a single-layer wind and dust suppression wall can reach 60 to 75%, while the effect of a double-layer wind and dust suppression wall can reach more than 80%.

 

　　Sources and Classification of Dust in Material Yards

 

　　Dust recovery from material piles can be divided into two categories: one is static dust recovery on the surface of the material yard, and the other is dynamic dust recovery during the material pile collection process.Static dust ignition is mainly affected by the surface moisture content of the material and the ambient wind speed, while dynamic dust ignition is closely related to the operation drop and loading and unloading strength.

 

　　Dust Prevention Mechanism and Effects

 

When wind speed reaches a certain threshold—known as the starting wind speed—particles on the surface of bulk materials begin to lift and disperse into the air. This process must overcome gravitational pull, inter-particle friction, and other resistive forces.

According to experimental research on dust diffusion from open-air material piles, the relationship between wind speed and dust generation follows the formula:
Q = a(V − V₀)ⁿ

Where:

• Q = dust emission rate

• V = actual wind speed

• V₀ = critical (starting) wind speed

• a = coefficient related to particle size distribution

• n = an index greater than 1.2

This equation shows that dust emissions increase exponentially with wind speed. Therefore, reducing on-site wind speed is the most effective way to control dust. This can be achieved through:

• Installing windproof and dustproof networks

• Applying wetting methods to increase material surface moisture

Both approaches are proven to be effective, especially in open-air material yards.

 

　　Key Features of Dustproof Networks

　　1. Aging Resistance and UV Protection

The product’s powder-coated surface effectively absorbs UV rays, slowing material degradation and extending service life. Its low UV transmittance also helps protect internal structures from sunlight damage.

　　2. Flame Retardancy and Impact Resistance

Made from metallic materials, the panels meet fire safety standards and withstand high-impact conditions. In testing, a 1kg steel ball dropped from 1.5 meters caused no damage—proving excellent structural integrity even under hail or high wind.

　　3. Anti-Static and Self-Cleaning Surface

The electrostatic powder coating not only prevents dust buildup but also breaks down organic matter under sunlight. The surface is designed for easy rainwater washing, maintaining cleanliness with minimal maintenance.
