Can summer umbrellas really protect against the sun? What kind of sunshade has the best sunscreen ef

Everyone doesn't want to see the big sun in summer, because it will be tanned after exposure to the sun for a long time, so many girls will prepare a sunshade when they go out in summer. Does the sunshade really have sunscreen effect? What kind of umbrella can protect against the sun?

What kind of umbrella has no sunscreen effect?

In summer, when I look at girls' paper on the street, I basically hold umbrellas, but I really can't bear it. Some people get a thin Lace Umbrella that can still see the sun to shade the sun. Xiaobian can't help laughing.

For this kind of umbrella, the difference between supporting and not supporting is only to reduce the burning feeling of losing the sun. As for the sunscreen effect, there is no! So, should it be black or black.

What kind of umbrella can protect against the sun?

Professional umbrellas, of course. If you still tan your umbrella, you may have bought a fake. Therefore, it is right to buy a professional umbrella. You must go to a specialty store to buy it. If you don't know how to choose. The following methods will help you:

UV test report

The most reliable solar umbrella has an ultraviolet test report. Some products do not have an ultraviolet test report, but there will be one on the umbrella or label.

The standard of anti ultraviolet performance of textiles is: when the UPF & gt; 30, and UVA transmittance & lt; At 5%, it can be called 'anti ultraviolet product' and will have anti ultraviolet logo.

UPF is the UV protection factor, with a maximum identification of 50 +. Although there is no guarantee that those with these marks must be genuine, there is no need to buy them. They can't prevent ultraviolet nonsense.

Umbrella surface density

Look at the fabric density of the umbrella surface. The greater the fabric density, the better. It can be looked after in the sun. If the textile density of the umbrella surface fabric is obviously sparse, the light transmittance will also be high. The intuitive performance is that the light in the umbrella is dazzling and gives people a hot feeling. The anti ultraviolet ability is poor, and the sunscreen effect will not be ideal.

Umbrella color

Look at the color of the sunscreen umbrella. Under the same conditions, the darker the color, the better the UV resistance. For example, black, navy and dark green have better UV resistance than light blue, light pink and light yellow.

Does the vinyl umbrella have to be sunscreen

Everyone's understanding of the sun umbrella probably stays on black glue. I think someone with black glue can prevent sunscreen. Black glue is a kind of coating umbrella. The coating umbrella also has color glue and silver glue. From the sunscreen effect of the coating, black glue & gt; Color glue & gt; Silver glue.

It is undeniable that a good vinyl umbrella can reach the standard of [UPF & gt; 30 and UVA transmittance & lt; 5%]. However, the disadvantage of the vinyl umbrella is that the coating will reduce the sunscreen effect in case of water, and will fall off after a long time. So try not to use a vinyl umbrella as an umbrella. Those 'weather and rain' are just buying some gimmicks. Don't be silly.

In addition, the coating is durable, and the effect of last year's Vinyl Umbrella will be discounted this year. So it's best to change it in 2-3 years.

Do you still need an umbrella after sunscreen?

The person who asks this question must want to wear sunscreen and go out to have fun freely, but if you don't want to tan, you must take an umbrella!

Research and tests show that even if it is like a high-power sunscreen on the market, its UVA filtration rate, that is, UV protection, is not as good as a professional sunscreen umbrella.

Because the sunscreen used in sunscreen developed with the current scientific and technological level can not achieve full band protection against ultraviolet rays, especially UVA.

The right way is this

If the role of sunscreen is graded, the first is to avoid the sun, the second is to block, and the last is sunscreen. That is, after hard sunscreen such as hats, clothes, umbrellas, sunglasses and so on, you can use sunscreen to pick up leftovers and make up for omissions. And try to choose an opaque umbrella for better sunscreen effect.

Sunscreen needs to be absorbed 30 minutes in advance before it is effective.
