Scientists have made the whitest paints in the world. It can eliminate the need for air conditioning.


According to scientists, the whitest paint in the world was created in a laboratory at Purdue University and is so white that it can ultimately reduce or even eliminate the need for air conditioning. increase.

Paint now do it Guinness World Records As the whitest book ever made.

So why did scientists make such paints? It turns out that breaking the world record was not the researcher’s goal: controlling global warming was.

“When we started this project about seven years ago, we had energy savings and the fight against climate change in mind,” said Xiulin Ruan, a professor of mechanical engineering at Purdue University. I am. statement..

According to researchers, the idea was to create a paint that reflects sunlight from the building.

However, according to Purdue University, when this paint was really reflected, it turned white. The paint reflects 98.1% of solar radiation and also emits infrared heat. Because the paint absorbs less heat than it emits from the sun, the surface coated with this paint cools below ambient temperature without consuming power.

Covering a roof area of ​​about 1,000 square feet with this new paint could provide a cooling capacity of 10 kW. “It’s more powerful than the air conditioners used in most homes,” Luang said.

A typical commercial white paint will warm up without getting cold. Market paints designed to dissipate heat reflect only 80% to 90% of the sun’s rays and cannot make the surface cooler than the surroundings.

According to Purdue scientists, this paint makes it super white due to two characteristics. The particle size of barium sulphate in paint differs from that of a very high concentration compound called barium sulphate (also used in photo paper and cosmetics).

According to a news release, researchers at Purdue University have partnered with a company to bring this ultra-white paint to market.
