The PC solar panel is commonly used in a hollow two-layer structure. Compared with the three layer and four layer honeycomb rice shaped structure, the material performance is not much different. The only difference is that the four layer honeycomb structure is more solid in thickness and the thermal insulation performance is better when the weight per square meter is increased. Of course, the solid structure is also naturally higher than the two layer structure in the middle air. It is generally used in gymnasiums, natatoriums and other places with more requirements for lighting, thermal insulation.
The second layer of sunlight board is 0.8 times of that of the first layer, and the thermal insulation is 0.2 times; The third layer is one time of the first layer, and the thermal insulation is 0.5 times; The fourth layer is 1.1 times of the first layer, and the thermal insulation is 0.62 times; Generally, the insulation effect is good, including four layers of sunlight board, honeycomb sunlight board, three layers of herringbone type and well type. The more layers of sunlight board, the stronger impact resistance, and the better thermal insulation.
What is the difference between the reinforced multilayer sunlight board and the ordinary double-layer sunlight board?
1、 Advantages of multi-layer solar panels: more layers, good sound insulation, good heat insulation, and stronger impact resistance than double layers; However, it is difficult to bend the multi-layer structure sunlight plate for the vehicle shed with arch radian, and the effect is not very ideal.
2、 The cost of the multilayer structure sunlight board is higher than that of the double-layer sunlight board. The service life of the sunlight board depends on the upper layer, not the number of layers. Therefore, the service life of the multilayer board has not been extended.
3、 When constructing the daylighting roof, the keel density is too large, the distance between sandalwood strips is too large, or when it is necessary to increase the hardness of the plane and isolate noise for indoor partition, the use of multi-layer sunlight panels can play a good role.
