China board trading network news:
Noise pollution is also a type of pollution. As modern households live very close together, sometimes some noise can cause problems between neighbours. How can we prevent these problems? The use of soundproofed home improvement materials is a good way. What are the sound insulation materials in the room? Which is better?
The acoustic blanket is made of odorless EPDM rubber and dozens of organic minerals according to a certain ratio. The product is black, environmental protection is no odor, and it is quite soundproof material for low frequency and high frequency sound, which can effectively inhibit various Vibration transmission, the thickness of the material is 1mm, 2mm, 3mm range, the National Building Materials Agency detected, weighted noise reduction Rw were 23dB, 27dB, 30dB, the flexibility of the material is also very good, you can easily bend, arbitrary ribbon cutting, Construction is very convenient and fireproof soundproof material.
1, soundproof felt has the following advantages:
(1) The material is light and thin;
(2) soft, high tensile strength;
(3) Environmental protection, does not cause pollution to the environment;
(4) To suppress the propagation of sound waves at low frequencies;
2, polyester fiber acoustic board
It is an ideal indoor sound insulation material. Its raw material 100% polyester fiber has sound-absorbing, environmental protection, flame-retardant, heat insulation, heat preservation, moisture-proof, mold-proof, dust-proof, easy to cut, can be decorated, easy construction, good stability, good impact resistance, and independence. The advantages of good and cost-effective, rich variety of colors to choose from, can meet the needs of different styles and levels of sound-absorbing decoration.
3, crest sound-absorbing sponge
The noise-absorbing material of the wave-absorbing sponge is a kind of sponge formed by a special treatment of the equipment to form a concave-convex wavy shape. The interior of the sponge is filled with small voids and half-opening structures, which can absorb a large amount of incident acoustic energy and attenuate the sound waves. , to reduce the interference and reverberation of indoor sound reflections and improve the purity of the sound. The main performance characteristics are:
(1) high sound absorption rate;
(2) good heat insulation;
(3) Flame retardant grade B1;
(4) Close structure and stable shape;
(5) The weight is light and the construction is safe and convenient;
(6) Harmless to the human body, no pollution to the environment, no odor;
(7) Water resistance, strong drainage after flooding, no degradation of sound absorption performance, no change in shape, secondary use, easy destruction, no secondary pollution to the environment.
