Of course, the use of high noise insulation board in Hefei may also be limited by various reasons. Only when the new residential area pays attention to the noise risk near the traffic trunk road and the airport in the land acquisition stage, establishes the noise prevention consciousness at the beginning of the design, implements the principle of noise prevention layout, prevents the traffic noise from entering and invading from the outside, and handles all kinds of noise sources inside, so as to control the noise pollution. Building layout because the building has the reflection function to the sound wave, the good building layout will reflect most of the noise, creating a quiet environment for the community; on the contrary, the bad building layout will make the noise repeatedly reflect and superimpose in the community, and aggravate the noise pollution. At the same time, the lighting performance is more important in winter. Sealed windows can reduce the loss of heat in the house. However, industry insiders remind that many buyers have misunderstandings, that a good window insulation performance is a good window, in fact, windows have another very important function - sound insulation. According to a buyer, his family is of the type of Bashan house, because there are many windows, the sound of cars outside the window, the noise of children in the next door, and even the voice of people downstairs. It's really noisy. Floor insulation board product introduction: the product uses graphite polyphenylene board and protective film for composite, which not only has good sound insulation and heat insulation effect of polystyrene board, but also greatly increases the overall tensile strength of the material through the composite protective film. The product plays an important role in sound insulation and heat preservation in the floating building system. The industrialization of the material will play an important role in energy conservation and emission reduction in China. It has a very broad application prospect in acoustics, energy-saving building and other fields. It is a green environmental protection material with extremely low sound propagation speed and certain compressive strength. It does not decompose at high temperature and has no harmful gas emission. The structure can effectively prevent heat transfer. It is a solid material with low thermal conductivity at present. It is foamed by nanotechnology and has completely closed porous Network structure materials.
Hefei Shenghao thermal insulation material Co., Ltd. is an enterprise specialized in building acoustic technology, thermal insulation technology, clean technology and material research and development, production and sales. Main products: sound insulation board, building floor insulation board, floating floor insulation board, thermal insulation damping board, thermal insulation damping board, BGL insulation board, insulation board, EPS insulation board, polystyrene board, foam board, sound insulation cushion, etc. I want to inquire, Hefei Shenghao thermal insulation materials Co., Ltd. large manufacturers, direct delivery, large quantity, price is superior, compared with peers, the price is reduced by 30%. As long as the material of the ground sound insulation and shock absorption pad is polyethylene, and then with a high nano technology, its high density is synthesized, and the general thickness is no millimeter. The material not only has no other harmful substances similar to benzene, but also has excellent quality and good ductility. It has the advantages of anti-aging, waterproof, moisture-proof and heat preservation. Generally, it can be used for about 30 years without accident. Because the material is mainly polyethylene, the general Dao can be cut and the installation process is very simple. However, the ground should be cleaned before installation. If the ground is not smooth, it should be leveled first. Wushan composite heat insulation board floor insulation board product advantages: 1. Fire resistance reaches the level B1 of fire-resistant type, with strong fire-proof performance, stable and reliable; 2. Thermal conductivity ≤ 0.035w / (m · K), excellent thermal insulation performance; 3. Convenient and fast installation and laying of products; 4. Service life of products can reach 30-50 years.
Anhui composite insulation board Hefei Shenghao thermal insulation material Co., Ltd. process flow 3. Clear the obstacles on the working face, ensure the smooth moving space and safety of spraying hands, and maintain a good spraying distance. 4. Spray the spray nozzle in the right direction and keep the pressure in the right direction. 5. Master the spraying sequence to prevent voids or looseness at corners and back of purlins. 6. Adjust the working air pressure and feeding device to make the output rate and speed of thermal insulation fiber surface suitable. When using centrifugal glass wool as floating floor, several problems should be paid attention to. One is that the apparent density of glass wool should not be too low, otherwise the glass wool will be compacted and lose its resilience, which will not have the effect of vibration reduction. Second, the overall rigid floating construction surface should have enough strength (concrete must be reinforced) and necessary joints to prevent the ground from breaking, and the steel bars of φ 6 can be arranged with a spacing of 20cm; when reinforcing, the waterproof layer must be punctured to prevent water seepage of glass wool during concrete pouring. In recent years, the floating floor is a better solution to the problem. First, the laid elastic cushion separates the floor structure into two parts, which can effectively prevent the continuous transmission of noise in the solid, greatly alleviating the solid sound transmission. Second, the elastic cushion can reduce the floor resonance caused by impact sound and absorb sound energy efficiently. According to the test results of the building physics laboratory of Tsinghua University, the impact sound insulation loss of the floor with elastic sound insulation pad can be improved by 15-35 dB (related to the material of the sound insulation pad). Product standard of thermal insulation board on floor: Code for acceptance of construction quality of energy saving engineering of residential buildings (dgj08-113-2005, j10598-2005), code for green design of civil buildings (JGJ / t229-2010), code for design of sound insulation of civil buildings (GB 50118-2010), unified standard for acceptance of construction quality of building Engineering (GB 50300-2016) code for acceptance of construction quality of building ground engineering 》(GB 50209-2002) code for acceptance of construction quality of building energy conservation engineering (GB 50411-2014) code for measurement of sound and sound insulation of residential buildings "floor insulation board application scope: widely applicable to residential buildings, schools, exhibition halls, hotels, KTV, etc.
According to the quality law of sound insulation, the greater the surface density of the ceiling, the higher the sound insulation loss; conversely, the smaller the surface density, the lower the sound insulation loss. 2. The distance between the ceiling and the floor should not be too small, and it should be 1020cm in general. If filled with porous sound-absorbing materials, such as glass wool and fiber sound-absorbing cotton, the sound insulation loss can be further improved. 3. The suspender between ceiling and floor should avoid rigid connection. Generally, spring shock absorber is used to increase sound insulation effect. It is worth noting that the ceiling can only reduce the direct downward radiation of the floor, but not the lateral transmission of sound energy through the wall. Therefore, it is difficult to play its sound insulation role in building structure with large lateral sound transmission. (2) Along the side of the street set balcony, connected balcony is better. There are many veranda in high-rise buildings, which is conducive to noise prevention. (3) Closed balcony is equivalent to adding a layer of window, noise reduction about 10 dB. Floating floor is adopted in this paper. The sound insulation structure of floating floor is that the cushion composed of flaky, strip or block loose elastic materials is laid between the floor and the structural plate, and the protective layer is poured on the cushion to form the floating floor. This structure can reduce the solid sound energy transmitted from the floor through a certain thickness of elastic organization.
