Which sound absorbing material to install lime walls is easier and more economical

Shanghai Houyi Energy Saving Technology Co., Ltd. is the pioneer of China's sound-absorbing spraying coating technology and construction, the company has introduced and learned from foreign advanced equipment and technology, and has cultivated and created a professional talent team who is proficient in HY4 sound-absorbing coating spraying technology and construction. It has developed a series of spraying products: sound-absorbing coatings, HY5 ultra-fine mineral fiber spraying, HY6 hard mineral fiber spraying, HY7 curtain wall insulation and waterproof special spraying, etc.; It can be used in basement ceilings, exterior walls, elevator shafts, equipment rooms, libraries, churches, waiting halls, office buildings and other fields.

It is recommended to damping soundproof felt, which adopts the most advanced production technology in Europe and is a kind of soundproof material for wall produced in China. It is a green, economical and durable product with a service life of 50 years.

The base material of the sound insulation material product is a high-density EPDM or PVC polymer material. Due to the particularity of the polymer structure of EPDM and PVC, the acoustic impedance of the material is particularly high. At the same time, the sound insulation material is filled with high-density minerals in the production process, which increases the areal density of the sound insulation material, so that the sound insulation material shows excellent performance in isolating air sound and impact sound.

The internal damping of the sound insulation material is high, and it has an incomparable effect on the isolation of medium and low frequency noise. The unique flexibility of the sound insulation material makes it easy to suppress the generation of resonance. At the same time, the sound insulation material is compounded with other lightweight materials to avoid the occurrence of anastomosis effect.

EPDM or PVC and other polymer materials have the characteristics of unchangeable physical properties, which should not be broken and softened under high and low temperature conditions, so that the product always maintains the same sound insulation performance, and at the same time can target different frequencies of noise. If the sound insulation felt is used in combination with other sound-absorbing materials, such as cotton felt, foam or rock wool, its sound insulation performance will be better.

Landlord, according to what you mean, I guess you want to use polyester fiber acoustic panels, right? Of course, if you use flame retardant, it is conducive to fire fighting. Whether it is for household or commercial use, flammable ones are not good and more dangerous.

In the audio-visual room, what is needed is an efficient acoustic panel, but also a safe, decorative acoustic panel. As far as I know, there is a Korean decorative sound-absorbing panel with a thickness of 9mm and a density. It is widely used in the field of decorative materials and acoustic engineering.

From the perspective of material, which is the sound absorption of polyester fiber acoustic panels? : 100% polyester fibers are hot-pressed at high temperatures and made in the shape of cocooned cotton, using high-tech heat treatment methods to achieve material porosity, so that the highest sound absorption coefficient in the noise range of 125-4000Hz is above.

The decoration of polyester fiber sound-absorbing panels: the suppleness of traditional soft bags, the rich texture experience of natural materials, a variety of modern colors to choose from, and the simple combination of decorative shapes to achieve modern sound-absorbing decorative arts, can create a comfortable, quiet, modern, warm and elegant indoor environment.

Thermal insulation of polyester acoustic panels: The special material structure creates excellent thermal insulation properties and thus creates a very comfortable indoor climate space.

I'll give you an example, a good brand recognized in the industry, that sound-absorbing decorative art board is an environmentally friendly product, the material is non-toxic, will not produce and volatilize harmful substances, and has no harm to the human body. 2 kg per square meter, light and delicate, wide board width, suitable for cutting and cutting. And it needs to be stable, and it will not expand and shrink due to changes in temperature and humidity.

There is a sound-absorbing film that can be applied directly to glass or walls.

Sound-absorbing cotton is a porous light-density material, including sponge, mineral wool, organic and inorganic.

Sound-absorbing cotton is divided into A-level fireproof, B-class fireproof, B1-level fireproof, and non-fireproof according to fireproof. According to the shape and material, there are egg cotton, mineral wool, glass fiber, etc.

There is no such statement that the sound absorption effect is the best, all kinds of sound-absorbing cotton have their own characteristics, some places are to absorb treble, then the best sound-absorbing cotton effect is the best to absorb treble, some places to absorb the intermediate frequency, then the sound-absorbing cotton effect of the intermediate frequency is the best, and some places should be average, then the average effect of sound absorption is the best.

The cheapest is egg cotton, which is not fireproof, and light, in fact, it is a sponge thing, it should be the cheapest, but it should be cheaper, that is, the sponge with a non-concave and convex surface. You get what you pay for, and it's the same thing when used in **.

The effect is good and cheap, then it depends on the use of the occasion, according to the situation of site 1, the sound absorbing cotton with good effect and cheap effect may be mineral wool, and according to the situation of scene 2, the sound absorbing cotton with good effect and cheap may become glass fiber, which is to change according to the situation, not the absolute of the same.

Color: Pink, Blue, Yellow, Black and White.

The best feature is that the pyramid shape also provides a diffusion effect, which will make your sound more vibrant.

1.Opening: The opening structure is to optimize the process of increasing its internal porosity in order to increase its sound-absorbing ability, so as to ensure the sound-absorbing coefficient of the pyramid sound-absorbing sponge;

Therefore, using a small amount of pyramid sound-absorbing sponge in the room can get the expected reverberation time.

2.Density: The higher the density, the greater the ability to absorb low frequencies. The high-density structure of the pyramid sound-absorbing sponge makes it have a very wide absorption frequency band, and the absorption frequency of the pyramid sound-absorbing sponge can reach more than 500Hz, which ensures that there is a flat absorption curve in the indoor acoustic treatment; Even if you use it more, you'll hear a dry sound, not a muffled sound with the tweeter off.

Application principle: adjust the sound field and reverberation inside the room to make the sound pleasing to the ear.

Uses:1Home decoration walls, roof sound insulation and heat insulation, reduce road and subway noise;

2.entertainment venues KTV, recording studios, audio-visual rooms, theaters, television stations, radio stations;

3.laboratory, piano room, sound insulation and sound absorption treatment;

4.Cabin, engine room sound absorption and heat insulation, generator room, pump room noise reduction, cold storage constant temperature.

5.Different industries such as automobiles, home appliances, office electronic equipment, ships, etc.

Installation method: evenly coat the glue on the back of the sound-absorbing cotton, wait for the glue to dry 8, spread the sponge on it, and flatten it with a small force.

There is no need to do it away from the water. The walls that do sound absorption are generally very simple walls, such as the sound insulation effect made of lime board is not good, and the lime board is afraid of water, so it should be waterproof.

The most commonly used is mineral wool ceiling sound-absorbing cotton.

The decorative effect and sound absorption effect of polyester fiber acoustic panels are very good.

The sound-absorbing materials of the general conference room walls and ceilings should consider both the sound-absorbing effect and the decorative effect. The more commonly used ones are sound-absorbing soft bags, wooden sound-absorbing panels, polyester fiber art sound-absorbing panels, wood wool sound-absorbing panels, etc.

If the wall decoration effect is made of fabric acoustic panels, and the ceiling is made of perforated acoustic panels, thank you! ~

Nowadays, there are many sound-absorbing materials, including foam and fiber1

Generally, porous sound-absorbing materials are commonly used, such as: sound-absorbing soft packaging, wooden sound-absorbing panels, wood wool boards, polyester fiber-absorbing panels, etc.

In general, the lecture hall is a more serious place, so it is generally not suitable for sound-absorbing materials: wave peak sound-absorbing cotton, egg cotton, polyester fiber sound-absorbing board, wooden sound-absorbing board in the grooved wood sound-absorbing board, hole wood sound-absorbing board are more suitable for the lecture hall, if with sound-absorbing materials are more suitable!

Wooden sound-absorbing board, or use gypsum board to add rock wool in the middle, and then use a part of the soft package!

Wooden sound-absorbing panels (can be divided into: slotted sound-absorbing panels and perforated sound-absorbing panels), polyester fiber-absorbing sound-absorbing panels, sound-absorbing soft bags, Great Wall sound-absorbing panels, small Great Wall sound-absorbing panels, aluminum sound-absorbing panels, etc.

Use fiberglass fabric upholstery, beautiful, good sound absorption, and flame retardant.

These indoor sound-absorbing materials are sometimes determined by location, and the sound-absorbing materials are divided into internal and external sound-absorbing materials. The internal sound-absorbing materials are: polyester fiber sound-absorbing cotton, centrifugal glass sound-absorbing cotton.

Exterior decorative sound-absorbing materials are: polyester fiber sound-absorbing panels, wooden sound-absorbing panels: (wooden sound-absorbing panels are divided into:

Grooved wood acoustic panels, wood wool acoustic panels, perforated wooden acoustic panels). Perforated calcium silicate acoustic panels. These materials are more suitable, and you can choose both external and internal sound-absorbing materials according to your needs.

Cement partition panels, cement aerated blocks.
