Magical nanotechnology:
Nanotechnology is a high-tech that rose in the 1990s. Nanometer is a very, very small unit of length, and 1 nanometer is equal to one billionth of a meter. If you put a ball with a diameter of 1 nm on the soldier's ball, it is equivalent to putting table tennis on the earth, which shows how small the nanometer is. Scientists have created many objects by using nanotechnology, and today I will introduce one of them-nano umbrella.
Welfare 1- waterproof function
Nano-umbrella is a multifunctional umbrella, which is different from ordinary umbrella in many places. Its most powerful function is to "cut off water". When raindrops fall and touch the umbrella surface, an angle will be formed between different media (solid, liquid and gas), which is also called water antenna.
When the water antenna = 0, the contact surface is completely wet;
When the water antenna is-90, the contact surface is partially wet or wet, which is called hydrophilic state;
When the water antenna = 90, it is the dividing line of wetting or not;
When the water antenna is-90, the contact surface is not wet and belongs to hydrophobic state;
When the water antenna = 180, it is not wet at all.
As the name implies, the closer the contact angle is to 180, the better the hydrophobicity is.
According to the actual measurement, the water antenna of an ordinary umbrella is 63, and the contact surface is naturally wet. No wonder the umbrella cover is wet every time it rains. However, the water antenna of Zuodu nano-umbrella has reached 167, which is very close to the completely non-wet state. The water fell on the umbrella surface without getting wet. You walked gracefully under the umbrella, assuming it was fake rain outside.
Benefit 2-No water stains
Are you still worried that milk or soup will stain your umbrella? Don't worry, the "water-free" function can directly isolate milk or soup without leaving any stains.
Benefit 4- UV protection
Nano-umbrella can not only "cut off water", but also prevent ultraviolet rays. God, when the sun comes out, as long as you open the sunshade, the ultraviolet rays will be easily blocked. Nano umbrella has brought us a lot of convenience, and in the near future, our food, clothing, housing and transportation will have the shadow of nano.
Advantage 5- rain or shine, small and light.
This super hydrophobic umbrella can not only perform well in rainy days, but also be an all-around player in resisting ultraviolet rays.
The weight of the whole umbrella is only180g, that is, the weight of three eggs, which is not even as heavy as some models of iphone. Because it is small and light, we can only take it with us when we go surfing. Only when the weather is unpredictable can the best protection be provided.
Advantage 6- Wind resistance
Don't think this umbrella is not strong just because it is light and small, because with the help of black technology, light and strong are no longer opposites. The nano umbrella adopts an upgraded alloy skeleton, which greatly reduces the weight of the umbrella. The umbrella frame is designed with channel steel and bone-covered honeycomb, and the supporting bones are made of glass fiber, which can bear the tensile force of 10 kg and resist wind and rain.
In other words, holding a lightweight nano umbrella in your hand can cope with the sun, wind and rain. And the weather can no longer ruin your good mood. Intimate detail design, ingenious black technology design everywhere, even the detail design is very careful. The handle is small and lovely, and it feels super good to hold.
There are also freely retractable umbrella belts, rounded umbrella beads, elegant and wear-resistant umbrella caps, which reflect the beauty of ingenuity everywhere.
