Which color is the best sunshade?Summer sun is hot, hot, is the number one enemy of the skin, choose a good umbrella can greatly reduce the sun's lethality, but the quality of the market is uneven umbrella, how to choose a real "umbrella," but the trick. From a professional point of view, people often say that "sunshade umbrella, solar umbrella" is actually anti-ultraviolet umbrella, China Daily Miscellaneous Products Industry Association umbrella professional committee secretary-general He Lingjun told the "Life Times" reporter, choose this kind of umbrella should pay attention to the following three aspects. First, look at labels. Mainly look at the protection index, that is, UPF and UVA value, only UPF is greater than 40, and UVA transmittance is less than 5%, can be called anti-ultraviolet products, the higher the UPF value, the better its anti-ultraviolet performance. Generally, most of the logo on the market is "50 F + 50", and its protection function is enough. Second, look at the color. Under the same fabric condition, the dark umbrella has better UV protection effect. The biggest difference between umbrellas and other umbrellas is the anti UV coating, which prevents ultraviolet penetration. Third, look at the fabric. Thicker umbrella surface, the closer the fabric, the better anti-ultraviolet performance of the fabric, compared to cotton, silk, nylon and other fabrics, polyester is more sunscreen. If you want to know the sunscreen effect of sunshade, you may try it in the sun. The deeper the shadow and the lower the transmittance, the best sun protection effect. When buying umbrellas, brand products must be chosen. In general, regular manufacturers will use brand names in many places, such as the joints of umbrellas. In addition, the rain will corrode the anti UV coating. It is better to separate the sun umbrellas and umbrellas. If the umbrella is dirty, rinse it with water or gently rub it with your hands, otherwise, it will also affect the effect. |
