The sound-absorbing plate of the elevator shaft is made of sound-absorbing glass wool and sound-absorbing particles, and has a unique waveform structure.The sound absorption coefficient is high and the noise reduction effect is significant.Installed in a specific structure, it can achieve good sound insulation effect and is very suitable for sound absorption and noise reduction treatment of elevator shafts, elevator computer rooms, air-conditioned computer rooms, etc.
The internal fibers of sound-absorbing glass wool are interlaced and fluffy, and are a typical porous sound-absorbing material. The principle of sound-absorbing is that there are a large number of small pores connected internally and externally. When sound waves are shot into sound-absorbing glass wool, the sound wave energy enters the inside of the material along the pores, causing the vibration of air molecules in the pores, which are converted from sound energy to heat energy and consumed, achieving a good sound-absorbing effect. At the same time, spraying a layer of sound-absorbing particles (porous sound-absorbing material) on the surface of the glass wool corrugated plate is equivalent to adding an interface between materials of different capacities, which is conducive to the reflection of sound waves. Therefore, the special sound-absorbing plate for elevator shafts is unique in the field of sound-absorbing and noise reduction, regardless of material selection to structural design.
When used inside the elevator shaft, the special sound-absorbing plate can be directly fixed with special nails, which is easy to install and very high construction efficiency. At the same time, this product can also be composed of other wall materials, sound insulation walls or sound insulation ceilings.If the Anj-19T sound absorbing board is bonded to a 12mm thick paper gypsum board, its weighted sound insulation is 31dB.75×The Anj-19T sound absorption board is installed in the middle of the 50 keel double-sided double-layer gypsum board. Its weighted sound insulation is 54dB to meet the national first-level sound insulation standard.
1. It is the average sound absorption coefficient of 100-5000HZ.
2. NRC is the noise reduction coefficient, which is the arithmetic average of the sound absorption coefficients of 4 octave bands 250, 500, 1000, and 2000HZ.
Product specifications: Regular size: 600mm×600mm×50mm (can be customized according to customer requirements)
Product purpose: It is suitable for sound absorption and noise reduction treatment in various specific structures such as elevator shafts, elevator machine rooms, air-conditioned machine rooms, etc.
Product features: good sound absorption effect of the waveform structure, Class A non-combustible, environmentally friendly materials, easy installation and high construction efficiency.
