What is the difference between a hollow board and a sunboard?
But both have a lighting function, which sunshine board lighting performance and weather better and the lighting board is better acid and alkali resistance, not easy to be acid and alkali corrosion, the production process is not the same, the sun is a co-extruded, the production process Slightly more complicated. The lighting plate is connected to the tapping screw and must have a cover plate. Sun plate cold and heat deformation is large, easy to be self-tapping nail cut, so the sun plate in the self-tapping nail should open a larger hole. In the installation of lighting panels to consider the expansion of the lighting board.
The material selected for the panel should be FRP, and the selection material for the sun board is PC. The lighting board is fixed with aluminum fastener, and the corrugated board is fixed with a light plate and a self-tapping screw. The position of the lighting plate is generally set in the middle.
Sunshine board is one of the lighting board, most of the lighting board is made of FRP and the sun is made of PC (polycarbonate) made, a little PC board warranty period is 10 years and 15 years, The better FRP lighting board warranty period of 20 years, 25 years. Performance comparison, although the thermal conductivity of the lighting board than the sun board is low, but the lighting board is usually a single layer, thermal conductivity than the sun plate. That is the summer sun exposure, then, under the lighting board room temperature to be higher. Light transmittance, carrying capacity under normal circumstances 2 can meet.
