Detailed Product Description: | What are the principles of acoustic noise absorbing aluminum perforated ceiling is? (B) "sound absorption" refers to absorption of most of the sound of aluminum ceiling market, to reduce the reflection of sound waves. Use a very thin sound-absorbing material can achieve very good sound insulation. Perforated aluminum ceiling aluminum ceiling, depending on a variety of patterns constitute punching arrangement, composition novel Shanghai aluminum ceiling, with excellent muffler noise reduction. On the basis of non-woven fabric affixed stickers plus 40mm thick glass fiber is more very good muffler noise reduction. Possible to the acoustic impedance of the sound absorbing nonwoven punching aluminum ceilings phase impedance is reduced to the same level with the air. Forcing the sound waves pass through the nonwoven fabric structure, friction, this friction causes loss of kinetic energy, thereby reducing acoustic values. Shanghai Building Materials Co., Ltd. specializes Blue also answer for you! Aluminum ceiling basic inspection methods have? No ceiling concrete base: 1. Press the sequence of operations required construction. 2. Clean the grassroots level, and combined with a solid foundation gray aluminum ceiling company, without hollowing. 3. smooth surface, see the iron trowel marks, but no blistering, fading and cracking. The surface paint brush, you can check the quality requirements reference cylindrical wall emulsion paint quality inspection requirements. Ceiling aluminum ceiling, aluminum ceiling, Shanghai Blue is also provided by the Shanghai Building Materials Building Materials Co., blue also. Shanghai Building Materials Co., Ltd. also blue (shsongjiang076218.11467.com/) strong, credible, and so cut off and the ceiling industry in Shanghai's Songjiang District, accumulated a large number of loyal customers.
