Anti-ultraviolet principle of sunshade awning

The principle of anti-ultraviolet radiation is to reduce its transmission, so that ultraviolet radiation can be reflected or absorbed as far as possible. There are two ways to make it reflect or scatter. There are two kinds of conditions, one is metal coating, which is attributed to mirror reflection and regular reflection, and the other is pearlescent fabric, such as some Patio Awning and Shade Sail, which can scatter ultraviolet rays in the direction of reflection. Ultraviolet absorbent materials are added into the fabric fibers, or after finishing the fabric, some ultraviolet absorbent materials, such as nano-zinc oxide or titanium dioxide, are added.
Sun Shade Sail is the key of sunshade canopy's anti-ultraviolet effect. At that time, the anti-ultraviolet greenhouse is mostly nylon or polyester fabric, which is processed and disposed of after anti-ultraviolet treatment. Greenhouse appellations include silver tape, gold tape, pearl glue and so on. From the experimental point of view, the protective effect of silver glue greenhouse.
When choosing anti-ultraviolet greenhouse, we should pay attention to the quality of Patio Retractable Side Awning.
First, the shade canopy should be large rather than small.
Secondly, the deeper the color, the better the anti-ultraviolet ability of the fabric.
Thirdly, the light and sparse cloth shed usually has poor anti-ultraviolet adjustment.
Fourthly, the ultraviolet protection of sunshade canopy has little to do with its value. The value of sunshade canopy depends primarily on the material and style of the canopy bones.
Fifthly, the sunshade canopy in wet condition, because of the optical conduction of water, ultraviolet transmittance added, the protective effect decreased. Therefore, the wet shed should not be used as anti-ultraviolet protection.
Sixthly, in the external environment of our activities, ultraviolet radiation radiates from all viewpoints to the human body. The anti-ultraviolet awning can cover the head. If you can apply sunscreen and wear anti-ultraviolet clothing, you can maintain your body in many ways.
