The use of umbrella is very frequent, especially in rainy days and sunny days, it is a very happy thing to carry a sunny umbrella with you. But when choosing to buy, you may not pay close attention to its various problems, which leads to some common problems, such as poor quality, poor sunscreen effect and so on. Today, let's talk about some selection skills you need to know.
1, material
The important thing is the material of the umbrella. Everyone pays more attention to its service life. If it's only bought for a period of time and it's broken, then such umbrella can be lost. First of all, there are two parts of the atmosphere, one is the umbrella surface and the other is the umbrella bone. The material of umbrella surface is in direct contact with the sun and rain. It should not only have waterproof effect, but also not lose the sun protection function. Then, it should be ensured that the material is thick and tight. If the material is thick, the sun will not leak in. If it is tight, its waterproof performance will be better. Now many umbrellas on the market are made of polyester, mainly thickness and density. The material of umbrella bone determines its firmness and the structure determines its durability. Generally, there are 6 bones, 8 bones, 10 bones and other different designs. The larger the number of bones, the stronger the wind resistance and tenacity. The material of umbrella bone is also different. Aluminum alloy, glass fiber, stainless steel, etc. generally, aluminum alloy is the most cost-effective one, and has better rust resistance.
2. Sunshade effect
In summer, the most important function of umbrella is sun protection and sunshade. Whether an umbrella has this function depends on the material of a coating on its surface. Generally, there are black glue and silver glue, and the UV protection function of black glue is better. At the same time, silver glue coating is selected, and the sparse umbrella surface is relatively bad. And this kind of data can also be learned from the tag on the umbrella. There will be UPF index on it. Generally, those who are more than 30 are qualified. UVA needs to be in the range of less than 5%, which is the real sunshade. And the use of sunshade should be separated from the umbrella, because the rain may affect the surface coating, resulting in the reduction of sunscreen and heat insulation effect.
3. Size and specification
In addition to the quality problem, there is also a portability problem. Considering the convenience of going out and carrying, many people want to choose a small and exquisite umbrella, which used to be three fold umbrella, but its length is also long, generally more than 625px, but girls' summer small bags are generally about 500px, which can't be put into the bag, so they need to With this in mind, a five fold umbrella appeared later. The size of this umbrella is about 450px. There is no problem in storing small bags of memory, but it will be more difficult than three fold umbrella. At the same time, the opening diameter of the umbrella surface will be correspondingly smaller, which is more suitable for one's own use. Many boys have no requirements for size, so they may be sloppy about it.
4, details
Then I'll talk about the details. A lot of details have not been noticed. Although it's a small aspect, the influence of its umbrella is very big, and even it can't be used directly. For example, the quality of the umbrella support accessories requires the umbrella to be opened for use every time. Therefore, this accessory is particularly important. If the material is not solid, it can only be used for a period of time, or it can't be opened or closed. This kind of problem is quite common. Then there is the comfort of the umbrella handle. When we support the umbrella, the contact place with the umbrella is the umbrella handle. Only when we choose a more comfortable style, can we hold it for a long time, and there is no uncomfortable feeling.
You may not imagine that there are so many stresses in simply choosing an umbrella. In fact, this stress is not hypocritical, but a delicate pursuit of life. Don't underestimate these selection skills. A good umbrella can also make people happy. After using it, you will regret it, so the above skills are very helpful.
