You will find that umbrellas have the difference between rain umbrellas and sun umbrellas. As the name suggests, rain umbrellas are used to block the rain, while sun umbrellas are used to block the sunshine or ultraviolet rays. However, most people are not very familiar with the specific differences between them and whether they can be replaced each other. You should choose a suitable product based on the two differences and your actual needs. Then, what are the differences between sun umbrellas and rain umbrellas?
Compared with rain umbrellas, the umbrella frame of the sun umbrella is lighter, and some umbrella ribs are made of non-metallic materials. In addition, their biggest difference is that the surface and material of the sun umbrella are special, and the sun protection function is particularly good. In addition, it blocks ultraviolet rays. The ability is also very strong. After all, sun umbrellas are mainly used to reflect the sun’s ultraviolet rays and heat insulation, while rain umbrellas are mainly waterproof.
Therefore, if you buy a sun umbrella, you must pay attention to its anti-ultraviolet label: According to the national standard “Assessment of Anti-ultraviolet Performance of Textiles”, UPF (ultraviolet protection factor value) is greater than 30, and UVA (long wave ultraviolet) is transparent. When the overrate is less than 5%, it can be called a UV protection product, and the protection level standard is “UPF30+”; when the UPF is greater than 50, it indicates that the product has excellent UV protection performance, and the protection level is marked as “UPF50+”. Consumers should carefully check the protection level identification when purchasing.
In daily life, if the sun umbrella is used as an rain umbrella to protect from the rain, it will definitely destroy and affect the original UV protection function of the sun umbrella, because the sun umbrella is added with sun protection, generally silver inside, and this color is washed by rain It will disappear slowly. Therefore, when you choose a sun umbrella, you must Choose a sun umbrella with real sun protection function.
So, How to choose a sun umbrella with good sun protection effect?
Pay attention to the protection grade mark of the sun umbrella. Consumers should carefully check the protection grade signs when purchasing, and then choose the umbrella that suits them according to the local sun exposure. Standards at home and abroad generally use UPF value, which is the value of UV protection coefficient, to evaluate the UV protection performance of textiles. The UPF value is the ratio of the average amount of ultraviolet radiation to the unprotected skin. The larger the UPF value, the better the UV protection performance.
Choose a suitable coating: After using the silver glue anti-ultraviolet sun umbrella for a period of time, some of the silver glue will peel off due to wind and sun, especially the part in contact with the umbrella ribs. If the silver glue coating is on the outside, it will cause mottle and affect the appearance. It is better to choose the silver glue coating on the inside of the umbrella, which will neither peel off nor affect the appearance of the umbrella.
Pay attention to the service life of parasols: parasols receive the baptism of sunlight under the sun every day. Over time, the materials will wear out to a certain extent, resulting in a gradual decrease in the reflectivity of ultraviolet rays. No matter how careful you are when you store the umbrella, the life of the umbrella is only 2-3 years. If you want to make the umbrella perform its functions, don’t always use the old umbrella. Once the umbrella has reached its shelf life, Don’t hesitate, Get a new umbrella, such as compact umbrella.
