What kind of parasol is the most sun protection?

The strong ultraviolet rays in summer can easily lead to early skin, wrinkles and stains, and excessive sun exposure can also cause skin diseases such as erythema, heat rashes, and swelling.Choosing a solar umbrella with anti -ultraviolet function can play a good protective role in the skin.When ultraviolet rays penetrate the sunscreen umbrella woven, there will be 4 cases: part of the transmission through the fabric; some reflex on the surface of the fabric; a part of the process of penetrating the fabric fiber; some scattering after penetrating the fabric.The sun umbrella produced by regular manufacturers indicates the fabrics and the UV index in their trademarks. Is there any difference?
Can the umbrella in the anti -ultraviolet function be used to cover the penetration and kill of ultraviolet rays? The two small methods below can be roughly detected.Method 1. Put a new version of 100 yuan on the inside of the umbrella. If 100 words of ultraviolet anti -counterfeiting logo are blurred, or they cannot be seen, it means that this umbrella can block the ultraviolet rays of a certain band of bands, otherwise it means that the effect of UV prevention is poor.Methods Second, open a few umbrellas with different materials on the outdoors, and put a thermometer of the same model in the inside and outside of each umbrella. After 10 minutes of exposure, observe the difference between the inside and outside thermometer in the umbrella.The insulation and ultraviolet of the umbrella are good, otherwise the quality is not good.
Silver gel layer material Silver tape fabric not only has good anti -ultraviolet effect, but also is relatively cheap.When using it, pay attention to the coating of the silver glue not to rain, rainwater can damage the coating of the umbrella to reduce the sun protection effect.For long umbrellas, silver rubber coatings will be dark and dark. Sometimes you can find the marks of the coating. This is because the climate drying coating is shrinking. New umbrellas need to be replaced to ensure the sun protection effect.
Two new fabric TC color woven fabrics are a new type of fabric that can be washed water without affecting the sun protection effect.The light transmission rate is not high, and ultraviolet rays with wavelengths of 380, 300, 220 nanometers can basically be completely blocked.UV 250-400 nanometer bands are most likely to cause sunburn and dry skin such as skin and hair.There is also a kind of laser rhoda fabric, which is woven by high density crafts. The surface of the fabric is attached to many folding particles. Each small dot will change the color with the rotation of the light position, which plays a scattering effect on ultraviolet rays.These two fabrics have the best effects, but the price is more expensive.
The three fashion fabrics are fat and thin, the appearance looks like lace, super light and beautiful, but the light transmission rate of this fabric is high, and the sun protection effect is not good.The coloring cloth is a satin fabric, which belongs to polyester. The anti -ultraviolet effect is weaker than the silver glue coating.There is also a fabric on the market called pearl tape, which has a certain reflection effect on ultraviolet rays. The sun protection effect is also worse than the silver glue layer.
The homogeneous color is deeply better than detecting the percentage of various color polyester fabrics to penetrate the ultraviolet rays. The black fabrics ultraviolet rays are 5%; Tibetan green, red, dark green, and purple fabric ultraviolet rays are 5%-10%;Light red, pale green, and white fabric ultraviolet rays are 15%.Therefore, the same fabric has a better color than the lighter sunscreen.
