How do you install the soundproof blankets?
The appearance of sound insulation felt instead of the traditional sound insulation materials, fundamentally broke through the vacancy of domestic banks, to a certain extent, to solve the noise treatment needs of special acoustic places. Sound insulation felt can be used in the wall, ceiling, ground, pipe and other positions, is called "universal sound insulation material" by the industry, although some exaggerated. In recent years, the improvement of sound insulation technology makes sound insulation felt gradually popular, the cost of sound insulation felt is greatly reduced, and the function of fire protection, moisture proof, good toughness, environmental protection and so on is favored by the owner. The insulation volume of the soundproof felt reaches 27dB. So how to install sound insulation felt, and the matters that should be paid attention to during construction.
Installation method of sound insulation felt:
1, according to the needs of the construction position with wallpaper knife or scissors to cut the appropriate size and shape;
2. When pasting on the wall, the material joint should be overlapped (that is, overlapped) more than 50mm;
3, no self-adhesive products and other materials when the surface of the material should be uniformly coated with adhesive;
4, sound insulation felt alone when the need for auxiliary frame fixed, and ensure that the joint paste tight;
5, sandwiched between the two layers of plate when used, the joint needs to be aligned with strict;
6, in the keel and wall, floor, ground connection, plate and keel connection pad sound insulation felt can reduce the sound bridge effect, to avoid the decline in the volume;
Precautions for the construction of soundproof felt:
1. Attention should be paid to the direct rigid link between the plate, keel and wall, and the contact point of the wall should be used as a spacer to generate a "sound bridge" and reduce the amount of sound insulation.
2, the sound insulation felt material should be covered, and pay attention to the treatment of such as thin joints and other weak links, can not appear Shen leakage sound gap holes, so as to avoid sound short circuit, reduce sound insulation volume.
3, reserve all kinds of strong and weak electrical wiring, do a good job of sound leakage processing, so as not to cause sound leakage phenomenon.
4, often in the top of the lighting, exhaust fan, smoke sensor or air conditioning duct and other facilities, in this case, need to do sound insulation treatment above each component, at the same time, exhaust fan pipe, air conditioning pipe, pipe sound insulation treatment, special circumstances in the pipe inlet and outlet of the air should also be done.
5, for places with high requirements for sound insulation, the sound insulation treatment scheme must be used in the room.
