Overview

Introduction of cement wood wool board

Along with the innovation of building energy-saving wall materials and the development of waste-recycling and environmentally-friendly building panels, a new type of sound insulation, sound absorption, heat preservation, heat insulation, fire prevention, moisture resistance, moth resistance, nailable, sawable, and excellent decorative processing A new building functional material with high performance and light weight and high construction performance - cement wood wool sound-absorbing board is favored by the construction, decoration and design departments. , Paving and pressing boards, which belong to cement wood products, have properties that wood and cement products cannot match.

The function of cement wood wool sound-absorbing board

The reason why the cement wood wool sound-absorbing board is favored by the society is that it has good physical and mechanical properties and excellent architectural functions. Its related properties and uses are as follows:

1. The strength of cement wood wool sound-absorbing panels, the application strength of cement wood wool sound-absorbing panels in engineering, mainly manifested in bending failure load and bending strength, and its strength value depends on the bulk density, composition, arrangement of wood wool and curing time temperature and humidity conditions, etc.

2. Thermal conductivity, one of the constituent materials of cement wood wool sound-absorbing panels—wood wool is a poor conductor of heat. In terms of structural composition, it has non-penetrating holes, which constitute the heat capacity and thermal resistance of air, so cement wood wool absorbs sound. The thermal conductivity of the plate is very small, and its thermal conductivity is generally 0.08-0.13kcal/m·h·℃ due to the different bulk density.

3. Sound absorption and sound insulation. The bulk density of the sound-absorbing board is 350-45kg/m3, which is larger than that of the thermal insulation board. The sound absorption of the panels increases with thickness. But the method of use has a great influence on the sound absorption effect. For example, keeping the distance between the wood wool board and the building structure can significantly improve the sound absorption effect. It has been verified by experiments that nailing the 25mm thick sound-absorbing cement wood wool sound-absorbing board to the skeleton 25mm away from the wall has the same effect as nailing the 250mm thick board directly to the wall.

4. Fire resistance, cement wood wool sound-absorbing board is a refractory material, the greater the bulk density, the better the fire resistance. Burning with a torch, after the torch is removed, the board has a flame resistance time of 30.

5. Stability. The stability of cement wood wool sound-absorbing panels is mainly manifested in mildew resistance, insect resistance and weather resistance. Because the surface of wood wool is protected by cement and treated with mineralizer, it is not afraid of mold.

Specifications and applications of cement wood wool sound-absorbing panels

The specifications of cement wood wool sound-absorbing panels are: 1220*2440*15mm, 1220*2440*20mm, 1220*2440*25mm, and can also be cut according to the specifications required by customers.

Applications: Gymnasium, swimming pool, meeting room, exhibition hall, multi-function hall, dance room, museum, trading center, computer room, computer room, subway, ticket office, home theater, theater, studio, recording studio, etc.
