It is also an ideal acoustic delay or high-temperature sound-proofing material due to the low sound velocity properties of silica aerogel. The variable range of acoustic impedance of this material (103-107 kg / m2 · s) is an ideal acoustic impedance coupling material of ultrasonic detector. For example, the commonly used acoustic impedance Zp = 1.5 × l07 kg / m2 · s Of the piezoelectric ceramic as the ultrasonic generator and detector, and the air resistance is only 400 kg / m2 · s. Silica aerogel with a thickness of 1/4 wavelength is used as the acoustic resistance coupling material between the piezoelectric ceramic and the air. Can improve the transmission efficiency of sound wave, reduce the signal to noise ratio in the device application. The experimental results show that silica aerogels with a density of about 30 kg / m3 can increase the sound intensity by 30 dB as a coupling material. If a silica aerogel with a density gradient is used, a higher gain of sound intensity is expected.
1, High-tech, new aerogel material, good sound absorption, stable acoustic performance, pollution-free, light weight, beautiful, fireproof, thermal insulation, not afraid of water, physical properties, easy processing, The form of sound absorber, muffler, sound insulation structure, sound barrier, muffler room, sound insulation cover, can directly face the noise source, does not require any protective panels and other sound-absorbing filler.
2, With excellent acoustic performance: the average sound absorption coefficient ≥ 0.80 (125-4000Hz frequency range); at the same time with the board after spraying water and sound-absorbing performance does not change the excellent acoustic performance.
3, Aerogel sound-absorbing material, is a high-purity silicon dioxide material, is the closest natural material, is currently the only non-environmental pollution caused by the new green high-tech products.
4, Aerogel sound-absorbing material is currently the Chinese Ministry of Public Security, Ministry of Housing and Urban recommended the best building materials.
5, Aerogel sound-absorbing material is non-flammable fire retardant, weather resistance, corrosion resistance, anti-aging, stand the wind, rain, sun, is a non-combustible products.
6, With good electromagnetic shielding performance.
7, Aerogel sound-absorbing material can be sawed, can be any bonding, riveting, plug, easy to install.
8, Aerogel sound-absorbing material can be made into various forms of sound-absorbing material, but also combined into various forms of sound absorption, sound insulation body.
