Scientists working at Purdue University in Indiana, USA; announced that they have developed the world’s whitest paint ever to combat global warming.
It has been noted that the world’s whitest paint reflects 98.1% of sunlight, cooling the environment it is in even more than an air conditioner.
Developed to reduce global warming:
The white paint developed by Xiulin Ruan, a professor of mechanical engineering at Purdue University, and her students has entered the Guinnes Book of World Records as the owner of the title of ‘the whitest paint ever made’.
Stating that the paint was developed by him and his team with the aim of ‘helping to reduce global warming’, Professor Ruan said that the paint that helps energy saving and climate change was obtained as a result of a seven-year study process.
The paint, which was developed in the university laboratory and was first born from the idea of repelling sunlight from a building; It was stated that a surface coated with this paint cools below the ambient temperature without consuming power, since it reflects 98.1% of sunlight and emits infrared heat and absorbs less solar heat.
“Stronger than most home air conditioners”
At the end of the research, it was discovered that the white paint used to completely paint a roof surface of approximately 92 square meters can provide a cooling power of 10 kilowatts. “This is more powerful than most home air conditioners,” said Professor Ruan.
An ordinary white paint, far from cooling the environment, actually makes it much warmer. It is known that 80 to 90% of the paints on the market reflect sunlight, while at the same time causing the surface to heat up more.
The scientists behind the study; He says there are two main reasons why the paint is “the whitest paint in the world”. The first of these two reasons is that a very high concentration of barium sulfate, a chemical substance used in paint, photographic paper and cosmetics, is used. The second reason is the presence of different particle sizes of barium sulfate in the paint. Thanks to the wider size range, the light from the sun makes the spectrum spread even more.
