A beautiful TV background wall adds color to the living room space. The material of the TV background wall is also diverse. While paying attention to the aesthetics of the decoration, health and environmental protection can not be ignored. Let's take a look at the living room TV background wall to see what material is good. The use of materials is very flexible in the TV background wall. The commonly used materials are glass, stone, wood, wallpaper, wall paint, plasterboard, ceramic tiles, etc. Different from the usual style of each material that people usually think of, almost any material can be used as a TV background wall, and each material can also display a completely different style. Taking glass as an example, glass is divided into back paint glass, art glass and semi-matte glass. Frosted glass is a semi-transparent material that generally gives a feeling of sorrow. Because of the visible light behind it, if you put old newspaper, kraft paper or dyed cloth with Chinese characteristics on it, you can create a modern feeling; if you put an abstract pattern on the back of it, it will create avant-garde Style; if you use a classic paper-cut, etc., it is a Chinese style. The same is true for wood, wallpaper, and wall paint. Due to the different materials used, the combination of combinations and colors are different, and various materials can create a variety of styles. In general, stone is mostly used in European styles, and the cost is relatively expensive, about 500-1000 yuan per piece. The back paint glass is about 100-500 yuan per square meter, the good art glass can reach more than 1000 yuan/square meter, and the gypsum board is about 100 yuan per square meter. Tiles are mostly laid on the ground, but as a TV background wall and other local decoration will have a tough alternative style, but its cost is high, but also need to consider the owner's acceptance of this style. In view of the variety of materials that can be created in a variety of styles, the selection of materials should try to choose products that are relatively inexpensive. Since each material can create different styles and the cost of each material is different, in addition to considering how to behave, it should be combined with the cost.
Pipe fan selection control parameters for the air volume, total pressure, efficiency, noise, motor power and so on. Depending on the physical and chemical properties of the gas being transported, fans of different uses are selected.
Features
1. Pipe fan selection control parameters for the air volume, total pressure, efficiency, noise, motor power and so on.
2. According to the physical and chemical properties of the gas being transported, select the fan for different purposes. Such as the delivery of clean air, should choose a general fan; transport flammable and explosive gases, explosion-proof fan should be selected; corrosive gas transmission, corrosion-resistant fan should be used.
3. Ventilator selection, should consider the leakage of piping system losses, calculation errors, and the actual fan fan, the negative pressure deviation, the general use of air flow 1.05 ~ 1.1, wind pressure of 1.10 to 1.15 safety factor. However, it is neither too large nor too large to prevent the fan from operating in an area of low efficiency for a long time.
4. Pay attention to the matching characteristics of the pipe network resistance characteristics and fan characteristics. In order for the ventilator to operate stably, the ventilator should be operated near its maximum efficiency point. The operating point of the ventilator is located on the right side of the full pressure peak point in the performance curve (ie, on the gales side and generally at 80% of the full pressure peak) ).
5. For ventilation systems with muffler requirements, fans with high efficiency and low impeller circumferential speed should be selected first and operate near the highest efficiency point. Should also be based on the ventilation system noise and vibration propagation, take the appropriate noise reduction and damping measures.
6. Pipe fan is through the blade shape changes, the air flow into the fan, the existing part of the axial flow, but also produce part of the centrifugal effect, so its performance is between the axial flow fan and Centrifugal Fan.
7. Piping ventilator can provide medium pressure and moderate air flow, ventilation system used in high-rise civil buildings are more appropriate.
Installation points
1) The natural frequency of the basic device shall not be greater than 1/3 of the motor and fan speed;
2) The difference between the vibration speed when the ventilator is running and the vibration speed when the ventilator is stationary should be more than 3 times.
2. Ventilator inlet and outlet connections between the duct should be set flexible joints. Into the air duct, air duct and other devices should be a separate support, and by the foundation or other components of the firm support firm, the chassis should not bear the weight of other parts.
3. Fan installed in the building components, should take measures to isolate vibration.
4. Fan installation can refer to the following national building standard design atlas.
5. Pipe fan can be installed in the straight pipe, with easy to take over, taking up the advantages of smaller space.
