Structure, principle, price and characteristics of cooling material made of TPX plastic

Two professors at the University of Colorado in the United States invented an epoch-making cooling material made of TPX plastic. Its biggest feature is that it can cool objects without refrigerant and electricity!

This film is made of a plastic called TPX. It looks like a plastic wrap, but under a microscope you will find many glass beads with a diameter of only 8 microns inside.

The exterior is covered with transparent plastic.

Ordinary plastics and ordinary glass beads can be combined to reflect sunlight back and prevent heat from penetrating downward.

Its cooling principle is “radiation cooling”.

The received heat can be emitted in the form of electromagnetic waves of 8 to 14 microns.

And for this wavelength of infrared.

The earth’s atmosphere is almost transparent and will not reflect, absorb or scatter.

That is to say, the heat emitted through this film can hardly be absorbed by the earth again.

It’s like taking out garbage to release heat into space.

Therefore, it can not only reduce the temperature, but also alleviate the global warming.

In addition, the cooling effect of this film is also quite strong.

It is enough to keep the indoor temperature at 20 ° C when the outdoor temperature is 37 ° C to lay a 20 ㎡ film on the roof.

Not only the effect is significant, but also the cost is very low.

It only costs about 50 cents per square meter, which is only more than 3 yuan!

Most importantly, it is not a concept product!

The inventor said that the production process of this material is not complicated, and there is no great obstacle in mass production. He hopes that it can be put on the market within 1-2 years.

Energy saving, low-carbon, efficient and green, this is simply the most ideal cooling material for modern people!

This invention has just been published in Science, a top science and technology magazine, and has attracted the attention of a large number of international top media.

It is worth mentioning that the two inventors, Yang Ronggui and Yin Xiaobo, are both Chinese professors.

Later——

Stick it on the roof without turning on the air conditioner!

Stick it on your mobile phone and you won’t be afraid of heat!
