Umbrellas are a must-have tool for going out in the hot summer. How should we buy a good umbrella? Let’s take a look at the tips for buying umbrellas in life. The price of sunshade umbrellas on the market ranges from more than ten yuan to several hundred yuan, which makes consumers look at flowers in the fog. How can they buy a truly UV-resistant umbrella with the least amount of money?
Look at the price first. Some umbrellas can only block the sun, and ultraviolet rays will still penetrate the fabric. Only through extraordinary coating treatment can they have anti-ultraviolet effects. So it’s not that parasols can protect against ultraviolet rays. According to industry insiders, a qualified, anti-ultraviolet sunshade can cost at least 20 yuan. Therefore, the effectiveness of UV protection for umbrellas bought for a few dollars is questionable.
Look at the UPF value. According to the “Assessment of Textile Anti-ultraviolet Performance” issued by the General Administration of Quality Supervision, Inspection and Quarantine, only when the UV protection coefficient value UPF is greater than 30+ and the long-wave ultraviolet transmittance is less than 5% can it be called an anti-ultraviolet product.
The anti-ultraviolet performance can be preliminarily judged according to the fabric type of the umbrella surface. Pay attention to the quality of the umbrella surface when buying an anti-ultraviolet umbrella. The umbrella with thin and sparse fabric generally has poorer anti-ultraviolet ability; the darker the fabric, the better its anti-ultraviolet ability. Generally speaking, cotton, silk, nylon, etc. have poor UV resistance, while polyester is better. In addition, the anti-ultraviolet performance is best for satin weave fabrics, followed by twill weave and plain weave, the darker the better. Some consumers believe that the thicker the umbrella, the better the UV protection performance, but it is not. There are various patterns of UV protection sun umbrellas, and the same color system can be distinguished from dark and light. Some of the edges of the umbrella surface are embroidered with antique flowers, while others are cut into lotus leaf edges. The umbrella surface design is fashionable, elegant, or simple. The shade of the umbrella surface will not affect the resistance to ultraviolet rays. Anti-ultraviolet sun umbrellas are also divided into two types: glossy and matt. Glossy umbrellas dominate the market and look pretty and lively; the production process of matt umbrellas is relatively complicated and looks unassuming, giving people a subtle and stable impression, but the price is not cheap.
It is worth noting that when buying silver glue anti-ultraviolet sunshades, consider the weakness of the silver glue. The silver glue will partially 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 is not easy to peel off and will not affect the appearance of the umbrella.
In addition, from the difference of umbrella ribs, there are long handle umbrellas and folding umbrellas. Whether an umbrella is durable depends on the ribs. In addition to the common straight and three-fold types, four-fold sun umbrellas have been introduced. It is more convenient to carry. Umbrella ribs account for a large proportion of the production cost of umbrellas, so pay attention to picking ribs when buying umbrellas. Multi-fold umbrellas are usually made of aluminum frames, which have a good feel and are not too large in a bag. They are easy to carry. However, this umbrella is not strong enough and can only be used for shading. If it encounters a sudden strong wind, it is easily damaged. One-fold umbrellas are usually made of steel frames, which are the strongest, but they are huge and difficult to store.
In addition, when the weather changes suddenly in summer, it is best not to use parasols as umbrellas. This will greatly shorten the life of the umbrellas, because the ribs of parasols are lighter than the ribs of umbrellas. At the same time, parasols and umbrella fabrics are also different. It’s raining. Long-term use will affect the shading effect of the parasol.
