How much of the installation of the sun board installation of a square meter
This assembly system is mainly used for small facilities such as garage, station canopy, rain eaves, greenhouses and many other alternative glass occasions. When using the wet assembly method, as shown in Figure 2, the basic requirement is that the sealing system is able to withstand a certain amount of movement of the plate, allowing thermal expansion without reducing its adhesion to the frame and the plate. It is generally recommended to use a neutral silicone adhesive and a wet sunboard assembly, but it is important to note that the chemical properties of the sealant used must be checked before use, and acid and alkaline silicone adhesives must not be used because these curing agents Plate cracking, especially when there is internal stress, the choice of sealant, in addition to considering chemical adaptability, but also focus on testing, elongation and weather resistance.
An effective space must be provided in the connection profile or in the mounting groove of the frame so that the plate is subject to expansion and load displacement. The linear thermal expansion coefficient of the hollow sun plate is 7 × 10m / mk, that is, the temperature of each 1 ℃, 1m × 1m board along the length of the expansion of 0.075mm, the user should be based on the location of the four quarters of the temperature difference between the calculation of the installation gap data: Such as the northern region, the maximum temperature of 40 ℃, the minimum temperature of -30 ℃, 1m × 1m of the plate to install the gap is 0.07 × 70 = 4.9mm
The sun panels are mainly made of PC / PET / PMMA / PP. English is sunlight, referred to as hollow board, pc sun panels to polycarbonate as the main raw material manufacturing. Sunshine board in the mid-80s into the building materials quickly.
