How long is the service life of a parasol? How long does it take to replace a parasol?

Parasols are used to block the sun and have UV protection effects. They are the most popular sun protection products in summer. Parasols have a certain service life, and their sun protection effect will be greatly reduced if used for a long time.

Generally speaking, a parasol can be used for 2 to 3 years. There are many things in our lives that will slowly depreciate, and parasols are no exception. Parasols are exposed to the sun every day, and over time, the material will be worn out. Once the sunscreen coating is worn out, the sunscreen effect will be greatly reduced. Therefore, when it reaches a certain period of use, you may wish to replace it with a new parasol to reduce the damage of ultraviolet rays to the skin.

It is best to replace a sun umbrella every year. Generally, the coating on a sun umbrella has a lifespan. If it is used for many years, the sun protection effect will be greatly reduced. In recent years, as science has analyzed the relationship between sunlight and health, more and more people have realized the necessity and benefits of using sun umbrellas in midsummer. However, sun umbrellas are exposed to the sun every day, and over time, the material will be worn to a certain extent, resulting in a gradual decrease in the reflectivity of ultraviolet rays. No matter how careful you are when storing it, the lifespan of a sun umbrella is only 1 to 2 years, so once the sun umbrella reaches its shelf life, don't hesitate to replace it with a new one.

1. First of all, try to avoid touching the umbrella with your sweaty hands.

2. The parasol should also be wiped clean, dried, and placed at room temperature for a while before being put away. It should not be put away in the sun when it is too hot, as this will easily cause the umbrella surface to age, become brittle, and rot.

3. It is best to use sun umbrellas and rain umbrellas separately. First, sun umbrellas are more beautiful and will get dirty after being exposed to rain. Second, the sun protection effect will be reduced after being exposed to rain. Sun umbrellas that can be used for both sun and rain are not included in this list.

The sun protection principle of sun umbrellas is mainly to reduce its transmission part so that the ultraviolet rays are reflected or absorbed as much as possible. There are currently two main methods:

The first is to reflect or scatter it. There are two cases: one is metallized film, which belongs to mirror reflection and regular reflection; the other is pearlescent fabric, such as some umbrellas, which can scatter the ultraviolet rays in the direction of reflection.

The second method is to add UV-absorbing materials into the interior of the fabric fibers, or to do post-processing on the fabric after it is completed by infiltrating some UV-absorbing materials, such as nano-scale zinc oxide or titanium dioxide.
