What need to be paid attention to in the installation of acoustic panel ceilings

The ceiling must be leveled well,

Whether acoustic panel ceilings really work.

Zhao Gong is responsible for the technical guidance of the sound-absorbing panel ceiling, the number of 156, the front 156, the middle is 3268, and the back four is 9388. It is best for you to understand the working principle of sound absorption panel sound absorption in advance, 1. Scattering attenuation:

When the sound wave propagates in the medium, it encounters an interface with different acoustic impedances and produces scattered reflections, which will cause energy attenuation.

When a sound wave propagates from one medium to another, the greater the difference in the acoustic impedance between the two, the higher the reflectivity of the sound wave at the interface between the two mediums, and the difference in the acoustic impedance between air and solids (walls, acoustic panels, etc.) is very large, almost 100% reflectivity.

Indoors, some of the sounds we hear are echoes of walls or other solid objects, and the scattered reflection of sound waves can cause a large echo to reach our ears.

2. Absorption attenuation:

When the sound wave propagates in the medium, the friction and heat conduction in the particle will cause attenuation, so the sound-absorbing panel mainly uses the principle of scattering attenuation.

At present, the sound absorption of indoor sound-absorbing board ceiling is mainly through the principle of absorption and attenuation, and there are many kinds of materials of sound-absorbing board ceiling on the market today, and generally different kinds of sound-absorbing board ceiling material, the effect of absorption and attenuation is not the same.

The ceiling is now a design that will be done in the family, and now people have economic conditions, so there will be requirements in all aspects, such as the ceiling sound-absorbing panel is also used by people now, so that the direct sound insulation effect between the building is good, thenCeiling acoustic panelsWhat are the methods of installing the hall? What are the characteristics of ceiling acoustic panels? Let's introduce it to you.

First, the ceiling sound-absorbing panel installation method

1.Installation of open keel acoustic panels.

The market often chooses light steel keel and aluminum alloy keel as the keel frame for sound-absorbing panel installation, first install the keel hall dust bracket according to the pre-calculated specifications, and then install the mineral wool board on the bracket, which is the installation method of non-slotting and falling pole plate, the main one is relatively simple, and it is also very convenient to maintain and replace it in the future, and the effect after installation is more three-dimensional.

2.Installation of dark keel acoustic panels.

The installation of the dark keel is generally inserted into the skeleton with a side groove or a falling plate, and the specifications of the sound-absorbing board should be prepared according to the size on the design drawing. In the installation process, attention should be paid to ensure that the shape of the light steel keel is maintained in the H shape, which is done in order not to let the keel be easily divided, the gap between the plates is reduced, and the decorative effect is more beautiful. However, the repair of the dark keel in the future will be more troublesome.

3.Flat mounting panels.

The installation method of flat paste is the simplest, as long as the plasterboard and thin plate are nailed with screws, but the flatness of the surface must be ensured. Then glue on one side of the board, then install the sound-absorbing board, and finally cover the sound-absorbing board with a layer of sound-absorbing glass wool, the thickness of which is generally about 40 mm, the density is maintained at 32 kg per square meter, and the length can be cut according to your own needs.

Second, the characteristics of the ceiling sound-absorbing panel

1.On the one hand, it can reduce the cost, reduce the unnecessary loss caused by the insufficient processing accuracy of the mold or the error of the mold in place at the press station, and improve the reliability and stability of the production line equipment; At the same time, it is also accompanied by a new defect, because there is no restriction on the surrounding aspects during the pressing process, it is possible that the position of the surface part of the sound-absorbing board is not completely compacted, and the perlite particles on the surface are easy to fall off after drying, which affects the aesthetics of the sound-absorbing board; In serious cases, the corners of the finished product may be loose and easily damaged after drying, reducing the yield of the production line.

2.In the production process of sound-absorbing panels, two raw materials of black material and white material are cleverly used, and the top with embossing is made of fine white material, and the bottom of the non-working surface is made of black material. The production process of the sound-absorbing board draws on the production method of ceramic tiles, that is, first presses the large piece and then cuts it according to the required size to obtain the finished product, which means that the final product is cut by the large sound-absorbing board and dressed up as slag, which is affected by the sharpness of the cutter and the nature of the cutting itself, resulting in a small amount of burr residue on the edge of the finished sound-absorbing board.

Ceiling sound-absorbing panel is now used by people when decorating the house, and it is also commonly used, so what are the installation methods and characteristics of ceiling sound-absorbing panels, I think you have also understood these problems through the above introduction.

Materials such as concrete, glass, marble and metal are widely used in modern buildings because they have smooth surfaces and high sound reflectivity, which reduces the sound absorption rate of the room. And the acoustic panel ceiling just happens to play the same role as them, which can play the role of sound absorption. At present, the ceiling materials of sound-absorbing panels are mainly divided into four categories: light steel keel gypsum board, gypsum board, plywood, and aluminum honeycomb perforated sound-absorbing board.

Let's take a look at these sound-absorbing panel ceiling materials in detail!

1. Light steel keel gypsum board of sound-absorbing board ceiling material.

The use of cover panels and binders to combine gypsum board with light steel keel to form light steel keel gypsum board.

2. Gypsum board of sound-absorbing board ceiling material.

The main raw material of gypsum board is building gypsum. Its advantages are light weight, high strength, thin thickness, easy processing, sound insulation, heat insulation and fire prevention, and it is one of the new lightweight boards that are currently focusing on development.

3. Guess the plywood of the ceiling material of the sound-absorbing panel.

Splint is also called plywood, and industry insiders call it fine spike core board. It is made of three or more layers of one-millimeter-thick veneer or sheet glue heat pressed, which is currently a commonly used material for handmade furniture.

4. Aluminum honeycomb perforated sound-absorbing panel of sound-absorbing panel ceiling material.

The aluminum honeycomb perforated sound-absorbing panel uses high-quality adhesive and aluminum honeycomb core to directly bond the perforated panel and the perforated backplate into an aluminum honeycomb sandwich structure, and a layer of sound-absorbing cloth is pasted between the honeycomb core and the panel and the backplate. Due to the unique honeycomb core structure in the honeycomb aluminum plate, the internal space is divided into many enclosed small spaces, which prevents the air flow, hinders the sound waves, and improves the sound absorption coefficient (which can be achieved).

Abstract: For the decoration of buildings, we should not only pay attention to the appearance, but also pay attention to its interior. So for the suspended ceiling, many people are very concerned.

Just like decorating the ceiling of the house can not only be good-looking, but also have a certain function, otherwise why install the ceiling, today, I want to introduce you to a ceiling material - mineral wool sound-absorbing panel. What are the advantages of sound-absorbing panel ceilings?

Acoustic panel ceiling is a new type of ceiling formed by finishing treatment with sound-absorbing panels or as the main material. The sound-absorbing panel ceiling has the characteristics of light weight, sound absorption, fire prevention, heat insulation, heat preservation, beautiful and generous, convenient construction, etc., and is suitable for the ceiling decoration of various public buildings.

Common sound-absorbing panel ceilings mainly include grooved wood sound-absorbing panel ceilings, perforated wood sound-absorbing ceilings, fabric sound-absorbing panel ceilings, wooden sound-absorbing panel ceilings, polyester fiber sound-absorbing panel ceilings, mineral wool sound-absorbing panel ceilings, etc. Today, I would like to introduce you to a ceiling material - mineral wool sound-absorbing panel.

First, the mineral wool sound-absorbing panels.

Mineral wool acoustic panels have a good decorative effect, because the surface treatment forms of this kind of panels are very rich. Common treatment methods are: knurling, punching, etc.

In addition, there is a very beautiful relief type mineral wool board. This kind of plate is stamped into shape, rich in patterns, and very beautiful. Therefore, many people like to choose this material for suspended ceilings.

2. Mineral wool sound-absorbing panel ceiling.

It is still very good to use this kind of plate ceiling. There are many mineral wool acoustic panel ceiling structures, and there are various ceiling forms. For example, the keel hoisting.

This form of ceiling is easy to replace the panels and install. A lot of people choose this way. In addition, there is also a way to suspend the ceiling, the composite paste method of the ceiling.

This form of suspended ceiling is very innovative, it is a flexible combination of multiple patterns on the same plane and space. Of course, there are also a little differences in different ways of suspended ceilings.

3. Advantages of mineral wool sound-absorbing panels.

The advantages of mineral wool sound-absorbing panels are just like the word "sound absorption" in its name, and the sound absorption effect is particularly good. In addition to this, it also has low fire resistance. This type of board is lightweight and is an energy-efficient building material.

It doesn't feel heavy to use, which is pretty good. It is worth mentioning that the flame retardancy of mineral wool sound-absorbing board is particularly good, because the main raw material of mineral wool board is mineral wool, which has a high melting point of 1300 degrees Celsius. Therefore, this kind of board has very good fire performance.

Fourth, the shortcomings of mineral wool sound-absorbing panels.

The surface of the mineral wool board is white, and it is easy to turn yellow if it is affected by other volatile solvents after using its suspended ceiling. That's not good. Another problem is that the strength of the mineral wool board is not very good, and it is easy to be damaged if it is accidentally extracted during hoisting.

I would also like to remind everyone that the mineral wool board is uneven due to the spraying process, so you must compare the color when buying it and buy an authentic mineral wool board.

Nowadays, people's requirements for the selection of Zhuangxi materials are getting higher and higher, and many families in order to make the living room environment quieter, even the selection of ceiling materials will choose sound-absorbing materials, but do you know what are the ceiling sound-absorbing materials, and are the ceiling sound-absorbing materials useful? For this reason, today I will deliberately introduce in detail the types of sound-absorbing materials for the ceiling and whether it has a sound-absorbing effect, let's take a look.

1. What are the sound-absorbing materials for ceilings?

1. Mineral wool board.

Mineral wool board is made of mineral fiber wool as raw material, which is characterized by good sound absorption and heat insulation effect, so it is usually used in ceiling decoration with high temperature and sound insulation. The surface of the mineral wool board can be painted and carved with patterns, so there are many options in terms of style. Because the production process of mineral wool board is thrown out by high-speed centrifugation, it is an environmentally friendly material!

It is a good soundproof ceiling material veneer.

2. Calcium silicate board.

Calcium silicate board, also known as gypsum composite board, is a multi-material that is generally composed of natural gypsum powder, white cement, glue and glass fiber. It has the characteristics of fireproof, moisture-proof and sound insulation, which can absorb excess water molecules in the room, but when the air is dry, it can release the preserved water molecules, so it is often used in the decoration of soundproof ceiling materials to increase the comfort of the room.

3. PVC board.

PVC board is a hollow synthetic plastic sheet with a light and strong texture. It is used for surface packaging of all types of panels. PVC board is also one of the commonly used materials in soundproof ceilings.

Of course, this material is also a very good one among the soundproof ceiling materials, and it is widely used.

4. Aluminum honeycomb perforated sound-absorbing panel.

It uses high-quality adhesive and aluminum honeycomb core to directly bond the perforated panel and the perforated hole back plate into an aluminum honeycomb sandwich structure, and pastes a layer of sound-absorbing cloth between the honeycomb core and the panel and the back panel. Due to the unique honeycomb core knot in the honeycomb aluminum plate, the internal space is divided into many enclosed small spaces, which prevents the air flow, hinders the sound waves, and improves the sound absorption coefficient (which can be achieved).

Second, is the ceiling sound-absorbing material useful?

Is ceiling soundproofing useful? Generally speaking, sound-absorbing ceilings are made of sound-absorbing materials, which can reduce noise by absorbing sound. Ceiling sound insulation does not mean that it is completely silent, it can only be said that it has reduced a lot of noise.

For example, if the old house is soundproofed by the ceiling, it itself has poor sound insulation, and there are many pipes in the wall, which is easy to transmit sound; Even if the ceiling is soundproofed, there will be a certain sound due to the floating of such pipes on the wall, etc., so the effect will be much worse. Therefore, the sound insulation of the ceiling is not completely useful, and the owners should choose according to the actual situation.

When installing the acoustic panel, you need to pay attention to all aspects to avoid the situation that the installation is not in place. What should I pay attention to when installing acoustic panels? PChouse will take you to find out.

1. Before construction, pay attention to the selection of boards, pay attention to the slight color difference of the boards, find out the center point of the pasted surface, draw a cross line, adopt the way of bricklaying, and start from the center point to arrange the board (it is best to wear gloves to avoid pollution).

Second, the cutting board surface with a steel ruler and a sharp utility knife for corresponding cutting or modification, to reduce the seam, the blade can be tilted inward when cutting, convenient for the board edge butting, reduce the gap.

3. Paste. 1. Cement or wood substrate: benzene-free universal rubber or white latex with neoprene as raw material can be selected.

2. The base surface of gypsum board on the paper surface: under the premise that it is not easy to get wet, you can choose white latex or wallpaper glue with cellulose as raw material (it should be fixed with nails immediately after brushing and pasting, so as to avoid the glue not drying and the board surface moving). Under the premise that it is easy or likely to get wet, you can choose all-purpose glue.

3. Polyester fiberboard is a porous material, which is easy to absorb glue, block holes, and affect the sound absorption function of the rear cavity. It is recommended that during construction, the glue can be brushed on one side (only on the substrate or keel, and the amount of glue brushing is slightly heavier than normal). At the same time, it can also be reinforced with studs.

Fourth, the yin and yang angle treatment can be done Yin and Yang angle treatment, and the method is the same as the construction method of aluminum-plastic panel.
