Problems solved by technology

[0002] At present, the daylighting panels on the market are widely used. Most of the daylighting panels cannot be used for a long time due to their low load-carrying capacity and poor impact resistance. For the daylighting panels exposed to the outside for a long time, they should have good corrosion resistance to avoid lighting. The board is corroded by the acidic substances in the rainwater. The application of the daylighting board on the house should have a certain degree of anti-ultraviolet.
Facing the poor impact resistance of lighting materials and poor lighting effects, it brings a lot of inconvenience in practical applications
