Five star hotel clubhouse project: when entering a hotel clubhouse, the first thing to notice is the overall feeling of the hotel, so the hotel design must pay attention to the decoration design of the wall and floor, especially the wall design must conform to the overall design style of the hotel. Not only in the aspect of design, but also in the aspect of acoustics, it should be designed well. It is almost perfect to use both aesthetics and acoustics.

According to the overall design style of the hotel, the decoration of the guest rooms should be different. Before decoration, it is necessary to pave for acoustics and apply it to absorbent materials. First, inorganic fiber spraying. The product has class a fire prevention, heat preservation, heat insulation, sound absorption and sound insulation at the same time. It is non-toxic, tasteless, non radioactive, antibacterial and not moldy. It can provide the hotel with good qualification in fire protection inspection and will cause unnecessary troubles.

1. Thermal insulation: A-18 series of products is a kind of high-grade thermal insulation material with high heat insulation value. Through testing the thermal conductivity, the value of in = O 035W / m · K ensures that the spraying layer has good thermal insulation performance. After spraying, the thermal insulation layer forms a sealed and seamless whole, effectively blocking the thermal bridge. It fundamentally solves the problem that the traditional thermal insulation profile has many joints, is easy to fall off and deform, and is pasted with the substrate The problems such as unfitness greatly improve the thermal insulation effect of building envelope.

2. Sound absorption and noise reduction: after the special spraying process of A-18 product, the internal fibers are interwoven to form a three-dimensional network structure with certain strength and toughness, which greatly prolongs the propagation path and time of the sound wave in the interior of the product, and further increases the conversion time of sound energy to mechanical energy caused by the vibration of the fiber caused by the sound wave, which makes the sound energy in the fiber spraying layer sharply attenuate Therefore, inorganic fiber spray sound-absorbing products have good sound-absorbing performance.

3. Fire resistance: A-18 series of inorganic fiber spraying products are natural inorganic materials. After testing, they are class a non combustible materials, which are non combustible, non fuming and non combustion supporting. It is in accordance with the testing requirements of gb8524-1997 "classification method for burning of building materials". This remarkable characteristic fills in the deficiency of other materials.

4. Safety and environmental protection: A-18 series of inorganic fiber spraying products belong to class a non combustible materials. They melt into liquid state at high temperature. They do not decompose. They are free of toxic gases and substances. They are non-toxic and tasteless. In line with the national "interior decoration materials adhesive limit of harmful substances" gbl8583-2001 standard test. Anti bacteria, no mildew, environmental protection and health.

5. Damping and sound insulation; A-18 product is sprayed on the surface of the steel plate to form an overall sealed sound absorption layer structure, which has a good sealing effect on the structural gap, can play a good role in sound damping, improves the vibration mode of the steel plate itself, greatly improves the sound insulation performance of the steel plate in the low frequency, thus improving the overall sound insulation ability. The experiment shows that the noise reduction effect is very significant.

6. Adaptability of complex structure; A-8 series inorganic fiber spraying products can be directly sprayed on any medium such as steel structure and concrete, with high-efficiency mechanical automation construction operation, and can be applied in any complex (special-shaped) structure or pipeline, hanging parts, dense area. Even in the space hard to reach by construction personnel, it can be easily sprayed. It fully demonstrates the plasticity and integrity of the product, and greatly improves the heat insulation effect and sound absorption effect of fiber spraying.

7. Decorative: A-18 series of inorganic fiber spraying products can be directly exposed outside after spraying. In order to ensure good acoustic effect, the surface of spraying layer does not need to attach other materials, but the surface can be treated with different colors to increase its beauty and decorative effect.

General hotel wall decoration design should conform to the overall design style. In the four or three walls of the waitai, you can change all or part of one wall to a color, such as bright orange, implicit dark blue with appropriate amount of purple, or elegant light blue, and then match different styles of decorative paintings or decorative components on the wall.
