Polyester fiber sound-absorbing board
Polyester fiber sound-absorbing board is called polyester fiber sound-absorbing board. It is a noise reduction material with sound-absorbing function made of polyester fiber as raw material by hot pressing. Can create a quiet working living space. Simple construction, through the woodworking machine, transform a variety of shapes.
polyester fiber sound-absorbing board can meet the requirements of different sound-absorbing and silencing effects. It is widely used in the field of sound insulation materials and acoustic engineering in China. It has been affirmed and praised by many famous domestic acousticians, and is deeply trusted and selected by mechanical designers and acoustic designers from all walks of life, become the choice of architectural acoustics, industrial noise reduction, product noise reduction and other engineering materials in most cities in China
polyester fiber is made of high-tech hot pressing and cocoon cotton shape to realize density diversity and ensure ventilation. It has become an excellent product in sound absorption and heat insulation materials. The highest sound absorption coefficient in the noise range of 125~4000HZ is above 0.9. According to different needs, the reverberation time is shortened, sound impurities are removed, and sound effect is improved, improve the clarity of the language. The product has the characteristics of heat preservation, flame retardant, light body, easy processing, stability, impact resistance, easy maintenance, etc.
sound absorption performance
polyester fiber sound-absorbing board and other porous materials have similar sound absorption characteristics. The sound absorption coefficient increases with the increase of frequency, and the sound absorption coefficient of high frequency is very large, the back cavity and the space sound-absorbing body formed by it can greatly improve the sound-absorbing performance of the material. The noise reduction coefficient is about 0.8 to 1.10, and it becomes a high-efficiency sound absorbing body with a wide frequency band.
Physical and mechanical properties
polyester fiber sound-absorbing board has sound-absorbing, heat-insulating and heat-insulating properties, and the material of the board is uniform and solid, full of elasticity, toughness, wear resistance, impact resistance, tear resistance, not easy to scratch, and large board width (9 × 1220 × 2440 ㎜).
polyester fiber sound-absorbing board has more than 40 colors, can be combined into a variety of patterns. Surface shapes are flat, square (mosaic), wide and thin. The sheet can be bent into a curved shape. Can make the indoor shape design more flexible, rich effect. You can even copy art paintings on polyester sound-absorbing panels by computer.
polyester fiber sound-absorbing board by the national fire testing center of the fire parameters of the test, the results show that it has good fire performance, in line with the national standard GB8624B1 level requirements.
The safety of polyester fiber sound-absorbing board is shown in two aspects. On the one hand, the material has excellent mechanical properties, is light in weight, and will not fall like some brittle materials such as perforated gypsum board and cement fiber pressure plate, etc. after being damaged by impact. On the other hand is the release of harmful substances, the relevant departments of the state testing, the formaldehyde emission standard requirements ≤ 1.5 mg/1, the test result is 0.05 mg/1. Meet the national standard level GB18580-2001E1 requirements, in line with the direct use of personnel operation area.
Easy dust removal and simple maintenance. Dust and impurities, with a vacuum cleaner and duster flick. Dirty places can also be wiped with water and detergent towel
