Can a parasol be used as a rain umbrella? How long is the service life of a parasol?

Although parasols and umbrellas are very similar, there are many differences between them. Parasols generally cannot be used as umbrellas. If the parasol is exposed to rain, the sun protection effect of the parasol will be affected, and the UV protection ability will not be that strong.

At present, most parasols can be used as rain umbrellas. There is a film on the outside of the parasol to block ultraviolet rays, which will be damaged after being exposed to rain, because there is a layer of sunscreen coating on the outside of the parasol, which will gradually fade due to frequent washing by rain, thereby reducing the anti-ultraviolet function of the parasol. The rainproof function of the parasol mainly depends on the overall physical structure of the parasol. When the entire umbrella is opened, its physical tension is very large. The fabric of the umbrella is pulled apart by a strong pulling force, and the spacing between each structural rope of the fabric becomes very small. Due to the tension on the surface of the raindrops, it is difficult to pass through such a small gap. Umbrellas do not have the function of sun protection, so they cannot be used as parasols. It is best not to use parasols as umbrellas, otherwise the sun protection effect will be lost faster.

This kind of sunshade has a very long service life. The key is not to use it to block rain, because many of these products are coated with a layer of sunshade and UV blocking powder. If you use them as umbrellas when it rains, the powder will slowly be washed away, and the sunshade and UV blocking effects will gradually become poor. So generally speaking, this kind of thing is not of poor quality, but it depends on how you use it.

Under the same fabric conditions, dark-colored umbrellas have better UV protection. The biggest difference between parasols and other umbrellas is that they have UV protection coatings to prevent UV penetration. Therefore, dark-colored parasols are the most sun-proof. Under the same conditions, the darker the fabric, the better its UV protection performance. In comparison, black, navy blue, and dark green have better UV protection than light blue, light pink, and light yellow.

Relevant doctors said that some umbrellas have silver glue on the inner layer of the umbrella. Although it blocks the ultraviolet rays from above, it may also reflect the light from the ground and increase the chance of suntanning. The most effective umbrella should have a black or dark inner layer and a silver glue coated outer layer for better sun protection.
