Sunshine board performance: 1) light transmittance: PC board transmission rate of up to 89%, with the glass phase deceased mother beauty. UV sun panels coated plates in the sunlight prolonged sun exposure does not produce yellowing, fogging, which is prolonged use of solar panels to the foundation, there is a good layer of protection uv sun panels, ten years after the transmission loss of only 6%, PVC turnover rate is as high as 15% -20%, the glass fiber is 12% -20%. (2) Impact resistance: impact strength is 250-300 times that of ordinary glass, acrylic plate thickness equal to 30 times that of glass of 2-20 times, with 3kg hammer, falling at 2 meters, no cracks, there are " no broken glass "and" ring of steel "reputation. (3) Light weight: Solid polycarbonate panels accounts for only half of the same thickness of glass, saving transportation, unloading, installation as well as the cost of the support frame, hollow sun panels lighter weight per square meter is between 1.0-3.5kg, reducing installation costs. (4) Flame retardant: National Standard GB50222-95 confirmed, PC board for the flame level, ie B1 level. PC board itself ignition is 580 degrees from the fire extinguishing, does not produce toxic gases when burned, do not contribute to the spread of fire. (5) UV: PC board one side coated with anti-ultraviolet (UV) coating, sheet surface is uniformly distributed with high concentrations of UV UV co-extruded layer of the sheet can be completely block UV damage, extend the panel life. (Product of single-sided and double-sided UV UV two kinds). (6) bendable: according to the design using cold-formed at the site, the installation arched, semi-circular roof and windows. Minimum bend radius is 175 times the thickness used, also be bent, such as solar panels 10mm minimum bend radius is 1.75 m. (7) Sound insulation: PC board insulation effect is obvious, than the same thickness of glass and acrylic panels for better sound, sound insulation, under the same conditions in thickness, PC board insulation than glass to enhance 3-4DB . In the international arena is the material of choice for highway noise barriers. (8) Energy conservation: Xia Tianbao cold winter insulation, PC board even less than ordinary glass and other plastics, thermal conductivity (K value), thermal insulation effect than the same glass, high 7% -25%, PC board spacer Heat up to 49%. Thereby greatly reduce heat loss, the device used to warm the building is environmentally friendly materials. (9) temperature adaptability: PC board does not occur at -100 degrees Celsius cold crisp does not soften at 135 degrees Celsius, in the harsh environment of its mechanics, so there was no significant change in mechanical properties can be adapted to different environments. (10) sun board weathering: PC board can be in the range -40 ℃ to 120 ℃ to maintain the stability of the physical indicators. Artificial weathering test 4000 hours, yellowing is 2, the transmittance value is only 0.6% lower. (11) sun board anti-condensation: outdoor temperature is 0 ℃, the indoor temperature is 23 ℃, indoor relative humidity below 80%, the material of the inner surface of the solar panels without condensation, does not affect any other special needs lighting company fog drip can be customized solar panels.
