Features Sunshine board is a transparent reinforced hollow board or solid board made of engineering plastic-polycarbonate plastic resin by heating and extrusion process. It has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, non-combustion and aging resistance. It is a high-tech solar panel with excellent technology, strong comprehensiveness, energy saving and environmental protection.
● Light transmittance: Good light transmittance (up to 88%).
Exposure to the sun will not cause yellowing, fogging and poor light transmittance.
● Weather resistance: The surface is covered with an ultraviolet-proof extrusion layer, which can prevent the resin from fatigue and yellowing due to sunlight and ultraviolet rays.
The surface extrusion layer has chemical bonds to absorb ultraviolet rays and convert them into visible light.
It has a good stabilizing effect on plant photosynthesis (very suitable for protecting valuable works of art and exhibits from ultraviolet rays).
Impact resistance: PC has the best impact resistance among thermoplastics. Even at high temperature, its potential deterioration and stress relaxation are small.
The solar panels made of PC have excellent impact resistance and can be kept for a long time in a fairly wide temperature range (-40℃~+ 120℃).
PC durable board is 200 times stronger than traditional glass and acrylic board is 30 times stronger, so it has the reputation of "unbreakable glass".
● Flame retardancy: according to the national GB8624-97 test, it belongs to the flame retardant grade B 1, with no fire drop and toxic gas.
● Temperature resistance: the low-temperature brittleness temperature is-100℃, the high-temperature softening temperature is 146℃, the allowable temperature under long-term bearing conditions is -40℃~+ 120℃, and the short-term bearing temperature is-100℃ ~+/kloc-.
● Sound insulation: It has good sound insulation effect and is the first choice for the sound insulation barrier of expressways in the world.
The sound insulation characteristics of materials are determined by hardness, weight and physical structure.
● Thermal insulation:
PC solar panel is one of the resins with small linear expansion coefficient.
The linear expansion coefficient of the plate in different directions is slightly different, with an average of 0.065 mm/m℃.
The thermal conductivity of PC solar panels is quite different from that of ordinary resin, which is 1/4 for glass, 1/300 for iron,11000 for aluminum,112000 for copper.
Good performance: it can be cut by hand and cold-bent without heating at room temperature.
Light weight, easy to carry and drill.
It is not easy to break when cutting and installing, and the construction is simple and good.
● Pollution-free and environment-friendly: Puning PC resistance board is odorless, non-toxic and radiation-free, and does not produce toxic substances during production and use. This product can be recycled, and it is a new modern green building material.
Selection points: A good sun board is heavy and transparent. If it is light in your hand and the transparency is poor, the quality is poor.
Installation and display schematic diagram of solar panel installation, solar panel installation and 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, the following spacing is recommended:
Answer: the thickness of the plate is less than 3.0mm and the spacing is 10~20cm.
B: The plate thickness is more than 3.0mm, and the spacing is 20~30cm.
C: If it is fixed in layers, the spacing is 20~30cm.
Note: If the PC board is directly fixed with tapping screws, the greater the screw spacing, the less likely the board will be damaged.
(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 initial diameter of the screw to reserve expansion space.
(3) When the position of the screw hole is too close to the edge of the PC board, it is very easy to break the board. Generally speaking, the position of the screw hole is 2.5 times larger than the diameter of the screw hole from the edge of the PC board.
For example, for a screw with a diameter of 4mm, the position of the screw hole should be at least 1cm away from the edge of the PC board.
(4) Don't lock the screw too tightly, otherwise it will be deformed and stressed.
(5) It is best not to use self-tapping screws for the screws locked on the PC analyzer, otherwise stress will be generated, and the stress will increase with the increase of plate thickness.
(6) In order to reduce the direct pressure of screws, gaskets can be used for filling, but PVC gaskets and some rubber rings will damage the PC board and cannot be used.
Recommended gasket materials are EPDM, silicone rubber and neoprene.
Technical content It is a transparent reinforced hollow board or solid board made of polycarbonate (PC) by hot extrusion process.
Good comprehensive performance and wide application range.
The cutting technology of the sun board has good toughness and can even be cut by hand.
But considering the quality and consistency of cutting, mechanical cutting should be chosen.
The design of the cutting tool for sunlight cutting is simple, but the sharpness of the blade is very important. The sharper the blade, the smoother the cut.
When the cutting machine is installed on a self-propelled trolley that can move vertically and horizontally, it must be properly adjusted to avoid that when the operation is unstable, such as the convex edge of the plate or sudden fracture, if the cutting saw does not respond correctly, it will damage the product and even damage the equipment.
The longitudinal walking speed of the self-propelled trolley should match the extrusion speed and can be adjusted at any time to prevent the length error, so the transverse cutting speed should be designed faster.
Modern and advanced double-sided cutter, with sharp blades on both sides, can get a very smooth cutting section.
If hot blades are used, the power required for cutting will be greatly reduced, while cold blades need more power for cutting.
If a thick plate is to be cut, the blade may break under considerable load.
It is suggested that it is best to install an automatic blade replacement system to avoid waste products when the blade suddenly breaks.
Cleaning method
(1) When cleaning, it must be cleaned with warm water below 60℃.
(2) When cleaning, use neutral detergent, and it is not allowed to use detergent that has corrosive effect on the sunshine board.
(3) It is required to gently scrub with a soft cloth or sponge dipped in neutral liquid.
It is forbidden to use rough cloth, brushes, mops and other hard and sharp tools for cleaning.
(4) When the surface has grease, wet paint, tape marks, etc. Can be scrubbed with soft alcohol.
(5) Wash the dirt thoroughly with clear water.
(6) Finally, dry and polish the board surface with a clean cloth, without obvious water marks.
Please pay special attention to:
Improper cleaning agent is alkaline solution, which will corrode the board surface.
It is forbidden to use esters, ketones, halogenated hydrocarbons and all substances that can dissolve or swell polycarbonate.
