Description

Technical Field

[0001] The utility model relates to the technical field of light steel keel gypsum board partition walls, in particular to a light steel keel gypsum board partition wall structure. Background Art

[0002] Working and studying require a good quiet environment. The secondary renovation of office buildings generally uses light steel keel gypsum board partition walls. Due to the light and thin material, the sound insulation effect is not ideal. The board seams have not been specially treated, which greatly reduces the sound insulation of the partition walls. The board seams form sound bridges. For example, if the sound insulation of the partition wall itself is 50dB, if a 0.01% gap is formed between the boards, the sound insulation will drop to 40dB.

[0003] The propagation of sound waves in the air conforms to the Huygens principle. The vibration of the sound source induces ultrasonic vibration. Due to the interaction between particles in the medium, when the sound wave propagates in a continuous medium, the vibration of any point will directly cause the vibration of the adjacent points in the medium. The interior of the porous sound-absorbing material has countless tiny pores, which are interconnected and communicate with the outside world through the surface. When the sound wave is incident on the surface of the material, the air inside the micropores vibrates, and the kinetic energy of the vibrating air is continuously converted into heat, causing the sound energy to be attenuated. In addition, heat exchange will continue to occur between the air and the pore wall, which also converts the sound energy into heat energy, thereby attenuating the sound energy.

[0004] Sound-absorbing materials are divided into porous sound-absorbing materials and resonant structure sound-absorbing materials. Traditional porous sound-absorbing materials such as glass wool, mineral wool, rock wool, etc. have low sound absorption efficiency and unstable performance;

[0005] The low sound velocity characteristic of aerogel makes it an ideal acoustic delay or high-efficiency sound insulation material. All sound-absorbing materials should be filled with pores, and the pores are interconnected and connected to the surface. Therefore, when the sound wave hits the surface of the material, part of it is reflected on the surface of the material, and the other part penetrates into the material and propagates forward. During the propagation of the sound wave, the vibration generated by it causes the air in the small holes or gaps to move, causing friction with the pore walls. The air close to the pore walls and the fiber surface is not easy to flow due to the influence of the pore walls. Due to the action of friction and viscosity, a considerable part of the sound energy is converted into heat energy. The interior of the aerogel is full of nanopores with both ends open and connected to the surface. Its specific surface area of up to 1000m2 / g shows that it contains a large number of pores. Therefore, when sound propagates in it, the sound energy will be greatly consumed by the large number of pore walls. This makes aerogel have a sound absorption effect dozens of times higher than that of ordinary porous materials. In addition, aerogel has very good thermal stability and corrosion resistance, and the surface-treated aerogel is hydrophobic, which makes it still have good sound absorption performance under high temperature and harsh corrosive environments.

[0006] Expanded perlite is a white granular material with a honeycomb structure inside, made by preheating perlite ore and then instantaneously calcining it at high temperature to expand it. Due to the production process, the particles have a large number of pores, forming open-pore perlite, which is an excellent sound-absorbing material. Utility Model Content
