晴雨两用伞的“神话
Many advertisements and commercials claim that their umbrellas can block both UV rays andthe rain. But expert analyzes reveal that once a parasol is used to block the rain, its UVcoating erodes. Gradually, it will lose its ability to block the dangerous rays, CCTV reported. So,if you want to keep your parasol long-term, prepare another umbrella for rainy days。
很多广告都宣称,他们的伞既可以防紫外线,又能挡雨。但根据中央电视台的报道,有专家分析,一旦遮阳伞在雨天用过,其紫外线涂层就会被侵蚀,会渐渐失去阻挡紫外线的功效。所以,如果想延长遮阳伞使用寿命,下雨天还是准备其他伞吧。
