As we all know, the characteristic of awning is shading, so in the sun, we mainly need to prevent ultraviolet rays, so today we are going to discuss the principle of awning anti-ultraviolet. The principle of anti-ultraviolet is to reduce the transmittance of ultraviolet light, so that the ultraviolet light can be reflected or absorbed as much as possible. There are two ways to reflect it or diffuse it. There are two cases, one is metallized film, which can be attributed to mirror reflection and regular reflection; the other is pearlescent fabric, such as some awning surfaces, which can scatter ultraviolet rays to the reflection direction. Another method is to add UV-absorbing materials inside the fabric fibers, or after finishing the fabric, add some UV-absorbing materials, such as nano-scale zinc oxide or titanium dioxide. The awning is the main material of the awning for UV protection. Most of its UV-proof sheds are made of nylon or polyester cloth, which is processed by UV-proof. There are silver glue, gold glue, pearl glue and so on on the surface of the carport. The test results show the protective effect of silver plastic shed surface. Pay attention to the quality of the awning awning when purchasing a UV-blocking awning.
First, the area of ​​the awning should be large and not small;
Second, the darker the color of the fabric, the stronger its anti-ultraviolet ability;
Third, sheds with thin and sparse fabrics generally have poor UV protection;
Fourth, the UV protection effect of the awning has little to do with its value, and its value mainly depends on the material and style of the awning;
Fifth, when the awning is wet, due to the optical conduction effect of water, the transmittance of ultraviolet rays is increased, and the protective effect is reduced. Therefore, wet sheds should not be used as anti-ultraviolet applications;
Sixth, in the external environment of our activities, ultraviolet rays radiate to the human body from all angles, and the anti-ultraviolet awning can block the head. If you can apply sunscreen, wear anti-ultraviolet clothing, etc., it can play a multi-directional maintenance role on the body. .
