What is a sunshine board and how much is it?

I don't know if you have seen this kind of material. In real life, solar panels are also used in many places, such as some greenhouses for planting flowers or for scientific research, all of which are made of solar panels. The light transmission performance of sun visor is very good, almost comparable to that of glass. Because it has some characteristics that glass does not have, it often has materials with good light transmittance in some buildings, so it will be widely used in some buildings. Just what are the specific characteristics of yangguan board? How is its price calculated? Let's have a look.

We should have seen the rain-proof buildings of the stadium, and we must have seen some parks or public places with some blue sheds for parking or resting. Yes, the material used is solar panels.

Sun panels are divided into hollow panels, sun panels, hollow sun panels, honeycomb sun panels, hollow sun panels, U-shaped locking sun panels, and single and double hook locking sun panels. And the above are all PC/PET/PMMA/PP materials. Because of its good light transmittance and thermal insulation, it has been applied in modern agricultural greenhouse construction, such as production greenhouse construction, trade greenhouse construction based on flower trading, greenhouse construction based on scientific research and so on. It is also often used in the construction of shade sheds and awnings.

Sunlight board is characterized by light transmission, the light transmission rate can reach 89%, and the light transmission loss rate is smaller than that of glass. It also has good impact resistance, which is 250-300 times that of ordinary glass, and can withstand high-strength impact without worrying about fragments and other problems. Some solar panels have certain ultraviolet resistance, heat insulation and fog drop prevention, and can be used in some facilities that limit ultraviolet rays.

Compared with glass, it is light in weight, which greatly facilitates transportation and installation. As mentioned above, the solar panel has heat insulation performance, because its ignition point is relatively high, and it can achieve flame retardant effect to a certain extent. In addition, it has certain flexibility and sound insulation effect, and is used on expressways to prevent noise.

As for the price of sunshine board, we need to refer to a series of problems such as its thickness, brand, quality and quantity. For your reference. For example, 10 mm Pute solar panel needs about 85 yuan per square meter, while Beijing Tongshun Fucheng Trading Co., Ltd. needs about 100 yuan per square meter, and the quotations given by some manufacturers range from 20-30 yuan per square meter. It seems that you need to consult the detailed price after choosing the right manufacturer. The price of yangguan board here in the market ranges from 30 to 300 yuan.

Use of sunshine board

Strange decoration of pavilions in gardens, amusement places and rest places; Interior and exterior decoration of commercial buildings, curtain walls of modern urban buildings; Aviation transparent container, motorcycle windshield, airplane, train, ship, car, motorboat, submarine and glass military police shield; Layout of telephone booths, advertising signs, light box advertisements and exhibitions; Instruments, meters, high and low voltage switchgear and military industry; High-grade interior decoration materials such as walls, roofs and screens; Sound barriers of expressways and urban elevated roads;

Product features (1) transmittance: p? The maximum light transmittance of C solar panels can reach 89%, which is equivalent to that of glass. UV coated panels exposed to sunlight will not turn yellow, fog and have poor light transmittance. After ten years, the optical transmission loss is only 10%, the PVC loss is as high as 15%-20%, and the glass fiber loss is as high as 12%-20%. (2) Impact resistance: the impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic board with the same thickness and 2-20 times that of tempered glass. Even if it is hit less than two meters by a 3 kg hammer, it has the reputation of "unbreakable glass" and "ringing steel". (3) Anti-ultraviolet: One side of PC board is co-extruded with anti-ultraviolet (UV) coating, and the other side is treated with anti-condensation, which integrates anti-ultraviolet, heat insulation and anti-fog. It can block the passage of ultraviolet rays and is suitable for protecting valuable works of art and exhibits from ultraviolet rays. (4) Light weight: the specific gravity is only half that of glass, which saves the cost of transportation, unloading, installation and support of the frame. (5) Flame retardancy: confirmed by national standard GB8624—2006, P? C solar panels are flame-retardant, Class B, and the ignition point of PC panels is 580℃. After leaving the fire source, they will go out by themselves, and will not produce toxic gas when burning, which will not encourage the fire to spread. (6) Flexibility: Cold bending can be adopted on site according to the design drawings, and it can be installed into arched and semi-circular roofs and windows. The minimum bending radius is 175 times of the thickness of the adopted plate, and it can also be hot bent. (7) Sound insulation: P? C the sound insulation effect of solar panels is obvious, which is better than that of glass and secondary stiffeners with the same thickness. At the same thickness,

method of erection

Strong edge condition

No matter dry assembly method or wet assembly method, no matter horizontal, vertical or inclined installation. In the installation project of hollow sun panel, the fastening of the edge is very important, and the following two points must be paid attention to: effective space must be reserved in the connecting profile or the mosaic groove of the mosaic frame, so that the panel can expand and shift due to load. The coefficient of linear thermal expansion of hollow solar panels is 7× 10m/m.k, that is, the panels of 1m× 1m will expand by 0.075mm along the length direction with the increase of temperature. Users must calculate the data of installation gap according to the temperature difference between the four seasons where the project is located: for example, the highest temperature is 40℃ and the lowest temperature is in the northern region.

Installation step

Transporting the board to the installation position;

Tear off the first bottom protective film;

Positioning with a cover;

Remove that protective film at the bottom of the second plate;

Positioning with a cover;

Stick waterproof tape on the joint of the two boards;

Press the layering right above the waterproof tape;

Screw installation method

(1) The screw spacing can be properly configured according to the thickness of the plate, and it is not good if the spacing is too small or too large. If the spacing is too small, it will sometimes cause stress and damage because it is too tight; If the spacing is too large, it will make the PC board unstable. Therefore, a lower spacing is recommended: Note: If the PC board is directly fixed with self-tapping screws, the greater the screw spacing, the less likely the board will be damaged by force. (2) The size of screw holes should take into account the difference of PC board expanding with heat and contracting with cold in Xia Dong season and book night. Generally speaking, the aperture of the screw should be 2~4mm larger than the minimum diameter of the screw to reserve expansion space.

In fact, when selecting goods, we should choose different standards of yangguan board according to the purpose, and we need to pay special attention to quality and price.
