In accordance with China's relevant environmental protection regulations, dust emission surcharge fees will be imposed. Additionally, the dust pollution from coal yards will have a certain impact on the residents' living, studying, working, and production in the surrounding areas. The construction of the covering net will significantly reduce dust pollution, beautify the landscape of the surrounding region, meet the requirements of environmental protection departments, and transform the previously heavily polluted material yard into a very aesthetically pleasing green eco-friendly yard, thereby achieving the goal of dust pollution control.

With the rapid economic development of our country, the volume of bulk goods such as coal, mineral powder, and sand灰 is increasing, and the resulting dust is increasingly drawing public attention. As national energy conservation and environmental protection laws and regulations become more stringent, dust pollution from coal yards and energy consumption issues have become a management focus in various regions. Implementing a full封锁 project at coal factories is not only costly but also limited by factors such as the span of the roof, requirements of the bucket wheel machine, ventilation, insulation, dust prevention, lighting, and the narrowness of the site, making it difficult to promote and implement currently. Meanwhile, the soil covering net technology, which is widely used overseas, is increasingly favored by enterprises due to its low investment and effective dust suppression.

Gaitu Net uses high-density polyethylene as raw material, woven into a mesh through special technology, serving as coal yard fencing. It effectively prevents dust, wind, and reduces the spread of dust. Additionally, it can be directly laid on coal piles to address dust pollution at its source. The flexible coal yard flame-retardant mesh is enhanced with V-agent, anti-aging agent, flame-retardant, and cross-linking reinforcing agents; boasting a high fire safety coefficient with a flame-retardant time exceeding 4 seconds. It is sturdy and durable, with a tensile strength coefficient of 220 KN/MM and an impact resistance coefficient compliant with GB16909-1997. It can also effectively absorb strong ultraviolet light from the sun, and the use of dual-color mesh contributes to urban beautification.

The Gaitu Net can be divided into two-needle and three-needle types.

The 2-needle geotextile is made from high-density polyethylene, woven into a mesh using special technology. It is used as a coal yard fence, providing dust control and windbreak to suppress dust飞扬. Additionally, it can be directly laid over coal piles to address dust pollution at its source. The flexible coal yard flame-retardant mesh is enhanced with V-agent, anti-aging agent, flame-retardant, and cross-linking reinforcing agents; boasting a high fire safety coefficient with a flame-retardant time exceeding 4 seconds. It is sturdy and durable, with a tensile strength of 220 KN/MM and impact resistance in compliance with GB16909-1997 standards. It can also effectively absorb strong ultraviolet sunlight, and the use of dual-color mesh is more conducive to urban beautification.

The 3-strand soil cover mesh is made from high-density polyethylene, woven into a mesh with special technology. It is used as coal yard fencing, serving to prevent dust, block wind, and suppress dust飞扬. Additionally, it can be directly placed over coal piles to address dust pollution at its source. The flexible flame-retardant coal yard mesh is enhanced with V-agent, anti-aging agent, flame-retardant, and cross-linking reinforcement agents; it boasts a high fire safety coefficient with a flame-retardant time exceeding 4 seconds. It is robust and durable, with a tensile strength of 220 KN/MM and an impact resistance coefficient that meets GB16909-1997 standards. It can also effectively absorb strong ultraviolet light from the sun, and the use of dual-color mesh contributes to urban beautification.
