How to tell the quality of lighting tile

There are many kinds of daylight tiles, and the names of daylight tiles in various regions are: daylight tiles, daylight panels, FRP daylight tiles, FRP daylight panels, FRP daylight tiles, FRP daylight panels, transparent tiles, FRP transparent tiles, FRP transparent tiles, FRP transparent tiles, sunlight tiles, FRP sunlight tiles, FRP sunlight tiles, daylight bands, FRP daylight bands, and FRP daylight bands, all of which belong to the FRP series products. The following is a brief introduction to glass fiber reinforced plastic (FRP) daylighting panels.
The service life of FRP daylighting board is closely related to its quality. For FRP daylighting board, high-quality daylighting tile has the following characteristics:
1、 The appearance of the daylighting tile is smooth, bright and wrinkle-free, and the color is pure and free of mottled, heterochromatic, and decor, which can effectively block the ultraviolet rays radiated by the sun, without impurities affecting the appearance such as * bubbles, cracks, and film warping. The spacing of the reinforcing ribs in the daylighting tile is uniform and free of distortion, so that the daylighting tile has better strength during installation and is not easy to break and tear.
2、 The overall thickness of the daylighting board is uniform, and there is no thickness on four sides and thin in the middle. The uneven thickness of the daylighting tile will shorten the service life of the daylighting tile. During the installation of the daylighting board with thickness on both sides, the overlap between the daylighting tile and the daylighting tile is not tight, which will cause air, water and dust. If there is a level 5 strong wind passing through the overlap of the daylighting tile, will it turn up the daylighting tile? In case of heavy rain, when the water passes through the lighting tile type, the drainage can not be discharged. Does the water seep into the enterprise's workshop through the place where the lighting tile is not closely overlapped, affecting the enterprise's production operation. Ordinary users can't identify the thickness of the lighting tile with the naked eye, so the small editor can help you identify the thickness of the lighting tile with a simpler method, as follows: weigh the specific gravity of the lighting tile. Generally, if the lighting tile manufacturers produce the lighting tile with a production specific gravity, the specific gravity of 1 meter wide 1.0 mm thick 6 meters is 8.3 kg, and the weight of 0.8mm thick 6 meters is 8.3 kg * 0.8MM=6.64 kg, then the specific gravity of 1 meter wide 1.0 mm thick 1 meter is 8.3 kg * 1.0MM divided by 6 meters=1.383 kg.
3、 The light transmission performance of the daylighting tile, the light irradiation is scattered through the daylighting tile, the light is soft and bright, and can effectively block more than 85% of the ultraviolet rays.
4、 The lighting tile is closely lapped with the color steel of the same specification, the section thickness is uniform, and the plate type is consistent with the color steel plate type.
5、 No discoloration, yellowing, exposed fiber and cracking of the daylighting tile after long-term use.
6、 The daylighting tile itself has good toughness, and there is no cracking during roof installation and nailing.
7、 The specifications and colors of lighting tiles are complete, and different light transmittance is selected according to different design requirements, including general lighting board, flame retardant lighting board, heat resistant lighting board, anti-corrosion lighting board, and flat FRP.
8、 The thermal expansion and contraction coefficient of the daylighting tile is close to that of the steel plate, and it will not leak because of the cracking of the thermal expansion and contraction at the nailing point.
The inferior board has the following characteristics:
1、 The appearance of the daylighting board is yellow or green, and the abnormal color is caused by the impurity of inferior resin. Wrinkle, * bubble crack and distortion of stiffener spacing are all caused by immature technology and relatively old daylighting equipment.
2、 The overall thickness of the daylighting board is uneven. The anti-aging ability of the daylighting board with two sides thick and thin in the middle and four sides thick and thin in the middle is far lower than the actual thickness in use. The weight of the daylighting board with uniform thickness is heavier. The daylighting board with two sides thick and thin in the middle and four sides thick and thin in the middle is completely to steal work and reduce materials to reduce costs. The winner is the business, and the user is suffering.
3、 Transparent and turbid, pine flower peel egg-shaped crack. Transparent turbidity is caused by the improper proportion of raw material glass fiber and resin, and the egg-shaped crack of pine peel is caused by the incorrect proportion of curing agent and unqualified raw material in the production process of curing daylighting board.
4、 It is loose with the color steel plate of the same specification, and the plate type is not consistent with the color steel plate type. It is mainly caused by the wear of the model, specification and mould of the daylighting tile manufacturer or the small opening of the mould.
