The umbrella sunscreen is a better you

Continued high temperature, sun has become a hot topic. Allegedly to prevent bask in the effect a great black umbrella has become this summer female darling, black umbrella, sunscreen effect is really superior? Nanjing City Quality Inspection Institute experts Dong Xiang Lin said on the market of the black umbrella price from tens of dollars to several hundred dollars, its quality in fact is also uneven.

"Decryption" umbrella

Dong Xiang Lin said that currently on the market of the black umbrella, in fact, sunscreen principle not the same: through some black umbrella in the back of a silver coating adhesive coating to achieve the purpose of sun protection, and part of the black umbrella umbrella surface is not undergo any treatment, no UV effect, and authentic black umbrella general through the dense umbrella surface and anti ultraviolet treatment to achieve the effect of sunscreen, prices are relatively high. The need to remind consumers, and is not the higher the price, prevent bask in the effect is better, if the black umbrella both lightweight, stylish appearance, good anti UV properties, then the price will not be too cheap.

Buy when to see the protection level

Umbrella drift not beautiful, look, we know, the effect of ultraviolet shielding an umbrella, could not be seen or even touched, the consumers how to judge it? According to the textile anti ultraviolet performance evaluation ", only the UPF (ultraviolet protection coefficient greater than 30 and UVA (long wave ultraviolet (UV) transmission rate is less than 5%, can be said that the anti UV products, protection grade standard for UPF30+; when the UPF is greater than 50, indicating an excellent product performance UV protection, protection grade marking for UPF50 +. Consumers in the purchase of shading before the first view of the protection of the level of identification, and then choose their own umbrella.

Sunscreen effect is not transparent

General anti UV umbrella umbrella surface there are three kinds of treatment methods: process in the use of anti UV dye in dyeing; the umbrella surface directly and coating UV coating; anti UV umbrella, choose UV shielding agent or UV absorbers on fabric for processing. But it is more difficult for consumers to determine whether to do a deal.

Intuitive judgment sunscreen effect is good or bad is that consumers take umbrella against the light look, if the light is strong, it indicates that the the umbrella to resist UV effect general, didn't even withstand ultraviolet function. In addition, from the umbrella cloth material itself, the thick cloth than the thin cloth sunscreen effect is good; dark fabric than light colored fabric anti ultraviolet performance is good; polyester fiber is better than the general effect of the sun.

The highest anti UV effect may not be good

The high price of some sun umbrella, and the umbrella fabric, handles, fittings, umbrella material, making process, packaging and brand effect are related, the anti UV effect is not the pricing main factor. Fabric, for example, currently on the market used to make sun umbrella fabric except the last silver glue, pearl glue and as export McBride, silver onion color DIMBOA, viz cloth new fabrics, these new materials can not only resist ultraviolet, and a good visual effect. However, the anti UV effect, the price is relatively inexpensive high-quality silver is the best.

Silver gel anti UV

Coating treatment is one of the most common treatment methods to prevent ultraviolet radiation. In general, silver coated umbrella performance is far better than the ultraviolet protection through dyeing and finishing processing of fabric. At the same time, silver plastic coating, or in the outside does not affect the effect of sunscreen, the best choice of silver in the inside, not easy to fall off.

If you want to choose a non coated sunscreen, you need to pay special attention to the fabric density. This is in fact the most important factor in the anti UV properties of non coated fabrics. Can be by the most direct method to test: the is void, opposite ray observations and the umbrella cloth, if almost can not see the gap, or the umbrella is arranged under the sun, shadow than black, fabric close degree is good; the second is look shiny, it is best to choose to have the luster of silk fabrics, such as color DIMBOA, McBride and so on. Related samples test results show that some degree of close good protection umbrella effect than general UV coated fabric.
