With the gradual popularity of green energy-saving buildings, the environmental performance and insulation noise reduction effects of buildings are also improving. As an important channel for air delivery inside buildings, whether the air ducts used in ventilation and air conditioning systems meet the needs of green buildings and can significantly improve indoor air quality under conditions of low energy consumption has become a primary focus in modern construction.

　　Traditional air ducts generally have characteristics such as high mechanical strength and low material costs. These ducts typically use traditional mechanical joints, with an outer layer covered with insulation material and a moisture-proof layer, and require the installation of silencers, making the construction process relatively complex. Compared to traditional air ducts, formaldehyde-free environmentally friendly soundproof air ducts have seen significant improvements, featuring no formaldehyde, high strength, heat insulation, thermal insulation, moisture resistance, and quick installation.

　　Formaldehyde-free environmentally friendly soundproof air ducts innovate traditional air ducts, upgrading in material quality, production processes, and more. They have advantages in green environmental protection, insulation noise reduction, mold prevention, and antibacterial properties, as well as fire and moisture resistance.

　　Green Environmental Protection Advantages

　　The lining layer of the formaldehyde-free environmentally friendly soundproof air duct is made of high-density formaldehyde-free glass wool fiber board, which does not contain toxic and harmful substances such as formaldehyde and ammonia, ensuring fresh and pollution-free air, improving the working environment, reducing environmental pollution, and providing ideal ecological and health benefits.

　　Insulation and Noise Reduction Advantages

　　As the insulation material for formaldehyde-free environmentally friendly soundproof air ducts, the fiber diameter of the formaldehyde-free glass wool board is particularly fine, less than 3 microns, thus providing better insulation and sound absorption effects compared to ordinary glass wool.

　　This glass wool board also has good soundproofing and noise reduction effects, with small holes formed by evenly distributed cotton fibers that can effectively reduce sound wave rebound, giving this air duct excellent noise reduction and energy-saving functions, greatly improving the quality and comfort of the indoor environment.

　　Mold Prevention and Antibacterial Advantages

　　The special inner surface layer of the lining board of the formaldehyde-free environmentally friendly soundproof air duct can protect the inner wall of the duct from erosion caused by dust and dirt due to improper maintenance of the filtration system, exhibiting excellent mold prevention, antibacterial, and moisture resistance properties, and can also reduce the growth of microorganisms on the inner wall of the duct, meeting the high standard requirements for air ducts in modern construction ventilation systems.

　　Formaldehyde-free environmentally friendly soundproof air ducts are a sealed, low-leakage duct system. In addition to their advantages in green environmental protection, insulation noise reduction, and mold prevention and antibacterial properties, they also play a significant role in fire insulation. This product has undergone fire performance testing by professional institutions and is classified as A-grade non-combustible fire material, with its fire resistance limit time meeting various time requirements.

　　As a star product of Beijing Hanjing New Materials, formaldehyde-free environmentally friendly soundproof air ducts have a very wide range of applications, such as in various ventilation, air conditioning, and heating systems, effectively reducing noise pollution and improving indoor air quality, playing an important role in maintaining a good indoor environment and the normal operation of industrial production.
