Choose a satisfactory sun umbrella. The deeper the shadow, the better the sunscreen effect!

Summer is coming. Looking at the big sun outside, I feel that there is only a handful of cumin between myself and the barbecue. In summer, I just want to live in the shadow of the umbrella, so I have to go out with the umbrella. But many friends found that the umbrella is still red and tanned. It turns out that the sunscreen umbrella needs to be carefully selected!

After mastering the following principles, it is actually very simple——

Selection principle of sunscreen umbrella

1. Look at the UPF value label

When the UPF value is 30 and above, it can be called a sunscreen umbrella.

The UPF value of most sunscreen umbrellas on the market is between 30-40, which is enough to deal with daily sunscreen.

2. Look at the umbrella surface coating

a: UV filtration

UV filtering method PG cloth is widely used in UV filtering method.

It has good UV resistance and long service life. Now there are also sunny and rainy umbrellas made of PG cloth, which are cheap and expensive.

b: Coating shading method

Sunscreen umbrellas with a coating for shading are affordable and cost-effective, so they are also the choice of most people.

However, the sunscreen performance of the coated umbrella will decline after raining, and the coating will fall off if the folding times are more.

3. Look at the size of the umbrella

In order to reduce the area of skin exposed to ultraviolet radiation, it is recommended that the larger the umbrella surface is, the better. At the same time, it is recommended to choose light, which is convenient and labor-saving.

4. Look at the color

Light colored fabrics are easier to absorb ultraviolet rays, and the darker the umbrella surface color, the better the anti ultraviolet performance. Therefore, try to choose dark umbrella surface.

Tip: even if it's an umbrella, don't choose any lace, tulle lace and several hole spicy species on the sunshade umbrella, it will be tanned!

Umbrella surface is the key to measure the effect of UV protection

Experts suggest that when carrying an umbrella, you might as well open the umbrella to see the shadow on the ground. The shadow is dark.

① Cotton, silk and nylon fabrics are not as good as polyester;

② Some umbrella fabrics are thin and sparse, and the fabrics selected are tight;

③ Satin fabric, then twill and plain;

④ The umbrella surface should be large rather than small;

⑤ The darker the fabric, the better.

Rain has a corrosive effect on the sunscreen coating. In order to maintain the sunscreen performance of the sunshade, it must be used separately from the umbrella.

If the umbrella surface is dirty, you can gently brush it with a soft brush dipped in clean water instead of rubbing it by hand, and do not wash it too frequently, otherwise it will also affect the sunscreen effect.
