90% of the content is discussing whether outdoor sunshades are UV-proof or not. Although UV protection is one of the strong functions of outdoor sunshades, the more comprehensive its functions, the more valuable it is. So how should we buy outdoor sunshades? And what about the color of the umbrella?
Umbrellas are not umbrellas, and outdoor umbrellas are not ordinary umbrellas. Usually, the umbrella cloth we use is only coated with a thin layer of silver glue, which is not resistant to ultraviolet rays. Outdoor umbrellas can also be used as umbrellas to cover the rain in the event of sudden rain, but if the outdoor umbrellas are often eroded by rain, the glue on the umbrella may fall off, reducing the protective effect. Therefore, do not mix.
Carefully check the protection class markings. According to relevant national regulations, only when the UPF (ultraviolet protection factor) is greater than 30 and the UVA (long-wave ultraviolet) transmittance is less than 5%, it can be called an ultraviolet protection product, and the protection level standard is "upf30+"; when the UPF is greater than 50, it indicates that the product is Excellent protection performance.” When purchasing outdoor umbrellas, consumers should carefully check the protection level mark, and then choose the umbrella that suits them according to the local sunshine conditions.
According to the fabric characteristics of the umbrella surface, the UV protection performance can be preliminarily judged. Generally speaking, cotton, silk, nylon and viscose have poor UV protection, while polyester fabrics have better UV protection. Usually used to make umbrellas, polyester fabrics, colored dingbu, Mackintosh, etc.
When choosing an umbrella surface, umbrellas with sparse fabrics generally have poor anti-ultraviolet performance, and consumers should buy them carefully. Because the fabric has the characteristic of shrinking, when purchasing the sunshade, the umbrella surface should be large rather than small.
The color of the fabric of the parasol is related to the UV protection performance. Under the same conditions, the darker the color of the umbrella, the better the anti-ultraviolet effect: the ultraviolet transmittance of black umbrella is 5%; the transmittance of navy blue, red, dark green and purple is 5%-10%; green, light The UV transmittance of red, light green and white umbrellas is 15%-20%. Our outdoor furniture shades are available in three colors: dark green, burgundy and khaki, all of which have a UV transmittance of 5%-10%. Other colors of umbrella cloth can be customized.
Buying outdoor umbrellas is mainly based on the scene of use. Commercial plazas and courtyard gardens have different styles, including sentry umbrellas, which also have their own design styles and materials.
