Introduction of sound-absorbing ceiling materials and process flow

Materials such as concrete, glass, marble and metal are widely used in modern buildings. Because of their smooth surface and high sound reflectivity, the sound absorption rate of the room is reduced. Excessive indoor sound intensity will harm people's health. In addition to the influence of indoor sound sources, external noise also plays a role. In order to protect people's health, sound-absorbing ceiling products have also been put on the market. Now let's take a look at the introduction of sound-absorbing ceiling materials and process flow.

Introduction of sound-absorbing ceiling materials

At present, the sound-absorbing ceiling materials are mainly divided into four categories: light steel keel gypsum board, gypsum board, plywood and aluminum honeycomb perforated sound-absorbing board.

Lightweight steel keel gypsum board: Lightweight steel keel gypsum board is a combination of gypsum board and light steel keel with cover board and adhesive.

Gypsum board: The main raw material is building gypsum. Its advantages are light weight, high strength, thin thickness, convenient processing, sound insulation and fire prevention, and it is one of the new light-weight plates that are currently being developed.

Plywood: People also call it plywood, and people in the industry call it thin core board.

It is made of three or more layers of veneer or thin plate with a thickness of one millimeter by hot pressing. It is the most commonly used material for handmade furniture at present. Aluminum honeycomb perforated sound-absorbing board: using high-quality adhesive and aluminum honeycomb core, the perforated panel and perforated back plate are directly bonded into aluminum honeycomb sandwich structure, and a layer of sound-absorbing cloth is bonded between the honeycomb core, panel and back plate. Because of the unique honeycomb core structure in honeycomb aluminum plate, the internal space is divided into many closed small spaces, which prevents the flow of air, hinders sound waves and improves the sound absorption coefficient (up to more than 0.9).

Introduction to the technological process of sound-absorbing ceiling

1. Shelf: The operating shelf should be a whole house shelf, firm and safe, and the height should be easy to operate.

2. Spring line: according to the axis on the wall and the horizontal line of 1m, use a ruler and other methods to lead the axis to the ceiling, and try to find a way according to the axis, first pop up the position of the light strip or light hole, and then pop up the position line of the main keel. When the elastic thread is divided into blocks. Pay attention to the symmetry of room ceiling layout. Lead the horizontal line to the ceiling elevation, and pop up two elevation lines around the wall, one is the surface horizontal line and the other is the derrick horizontal line.

3. Welding derrick: According to the position line of the main keel and the horizontal line of the derrick, pull the horizontal line with a small line, and weld the derrick and the large keel hanger according to the line. If that position of the embed boom is wrong,

Need to pick holes in the roof, according to the position of hanging steel. Then use cement mortar to plug the hole, and the boom should be painted with two anti-rust paints. 4. Making curtain boxes: According to the design requirements, curtain boxes or hardwood decorative boards are arranged around the ceiling to increase lines and enhance the three-dimensional sense. The curtain box should be flat, straight and square, which is the key to ensure the ceiling. Firstly, the iron parts of the curtain box are fixed on the surrounding walls with a nail gun, and then the wooden decorative board and the iron parts are connected with screws, so that the curtain box and the wooden decorative board form a closed frame.

5. Installation: One method is to install from the center line of the room to both sides, and then press the walls, lamp holes, manholes and other special parts after the overall installation in a large area is completed. Another method is to insert the side grooves of the sound-absorbing plate into the flanges of the main keel and the secondary keel, and then insert this block and another sound-absorbing plate. After the sound absorbing plates on the adjacent secondary keels are installed, the secondary keels can be pressed.

And proceed in sequence. 6. Topcoat: The topcoat can be used after the processes of power supply and ventilation are completed in the ceiling. When installing the panel, determine the pattern direction and install it in sequence. In order to keep the surface clean, the operator must wear gloves. After the surface layer is finished, pull the thread again and make the final adjustment.

I hope that the above introduction of sound-absorbing ceiling materials and process flow will be helpful to everyone.

The sound-absorbing suspended ceiling has the characteristics of light weight, sound absorption, fire prevention, heat insulation, thermal insulation, elegant appearance and convenient construction. It is suitable for ceiling decoration of various public buildings. If you need to know more, you can follow us.
