Sound insulation cotton is a common building insulation material, with good sound absorption properties. It can be made into wall panels, ceilings, and space absorbers, which can absorb sound energy in the room to reduce noise. Therefore, the installation of soundproofing cotton is very important. Then, Xiaobian will introduce how to install soundproof cotton and the role of sound insulation cotton.
How to install noise insulation cotton
The concrete step is to build a layer of light steel keel frame, fill the soundproof cotton in the frame, and put the sound insulation board on both sides of the frame. There are several kinds of sound barriers for the Australian Flying Chiff, which can be based on the requirements of the sound insulation effect of ktv, and install different sound insulation. If you want to have better sound insulation, it is best to paste sound-absorbing felt between the board and the frame. This kind of sound insulation will be even better.
In the acoustic damping of ktv floors, noise blankets and cushions are needed. The specific steps are to make the floor relatively flat, place a layer of cushion on the flat floor, and lay a layer of soundproof felt on the cushion so that the sound insulation will be better. Finally, cement or lime is poured on the floor. .
In the acoustic treatment of ktv suspended ceilings, vibration-reducing hooks, sound insulation panels, acoustic blankets, and sound insulation cottons are needed. The specific step is to build a light steel keel frame, and install a shock-absorbing hook between the frames of the floor. The sound-absorbing cotton is filled in the frame, preferably a layer of sound-insulating felt.
The role of sound insulation cotton
1, waterproof
Nowadays, the waterproof performance of most family cars is not very high. In particular, when it rains on a rainy day or after a car wash, we will see traces of water droplets in the door, and will quit for a long time. This way, it is very easy to make the car door metal rust. When the car door is soundproofed, the soundproof cotton will stick to the door iron, so that the soundproof cotton can play a role in waterproofing and prevent the door from rusting in contact with water. .
2, insulation
Soundproofing cotton has a good heat insulation effect, precisely because of this, the soundproofing cotton can not only reduce the raindrops on the roof when it rains, but also have a certain resistance to the hot sunshine in summer, and in the cold winter, soundproof cotton can also slow down. The heat in the car is emitted and the temperature inside the car is maintained.
3, extend the life of components
What I fear most about driving is the bumpy road. On this road, the car is always in a state of jitter, which makes people feel that the cars are almost scattered. If it is a long time, the consumption and wear of the internal parts of the car is great. In this case, if the doors are insulated, the integrity of the doors and the ability to absorb shocks will be increased, and the vibration energy of the car's sound can be absorbed by the sound insulation cotton. This will not only improve the comfort of the car, but also prolong the car. The service life of the component.
4, protect car paint
With the insulation effect of sound-insulated cotton, we can paste sound insulation cotton into the hood of the car, which can effectively prevent the high temperature of the engine from directly transmitting to the engine cover, not only protecting the paint on the surface of the engine cover, but also avoiding the effects of fog on the engine cover during rainy weather. Sight.
The characteristics of soundproof cotton
1. The sound insulation is large: it has high-performance sound insulation effect, and it can reach 50 decibels or more.
2. High sound absorption coefficient: The average sound absorption coefficient is 0.84.
3, weather durability: water resistance, heat resistance, anti-ultraviolet radiation, will not be caused by changes in rainwater temperature caused by performance or quality anomalies. The noise barriers of products are made of endurance plates, galvanized endurance plates, glass wool, and galvanized surfaces of H-steel columns. The antisepsis period is more than 15 years.
4. Sound insulation panel economy: Improve work efficiency, shorten construction time, and save construction and labor costs.
5, sound insulation board is convenient: install in parallel with other products, easy maintenance, easy to update.
6. Acoustic panel is light: The sound-absorbing panel series products have the characteristics of light weight and light weight, about 50 kilograms per square meter, which can reduce the load bearing load of overhead light rails and elevated roads, and can reduce the structural cost.
7, sound insulation board fire: The raw materials themselves are inorganic, fully meet the requirements of environmental protection and fire protection standards, fire prevention and so on up to A level.
8. High-intensity: In combination with different climatic conditions in various regions of China, wind loads are fully taken into account in structural design. Using 1.0-1.6mm galvanized sheet, through the numerical control equipment, suppress the groove to increase the strength, so that the product is resistant to typhoon 10-12 class, pressure 300kg/m2.
9, waterproof, dustproof: design fully consider the waterproof, dustproof, its angle is set to 450 degrees, in the dust or rain environment, its sound absorption is not affected, the structure has been set dust drainage measures, to avoid the internal components Water.
Editor's summary: The method of how to install noise-insulating cotton and the role of noise-insulating cotton are introduced here. I hope to help everyone. If you want to know more about yourself, you can follow the information on this site.
