New Delhi: In primitive times, the Lipa system was used to keep the house cool. Therefore, along with the natural environment in the house, there was also a feeling of coolness. But with the development of technology, AC is found in everyone’s house today. Press a switch and get instant relief from the heat. But now such colors are also made, by painting which the house remains cool.
In countries where there is an outbreak of Suryanarayan, white color is specially seen at home. Hence it protects from sunlight. The same method has been further developed to create a new product that keeps the house cool. It can be painted on any wall and the temperature can be reduced by up to 6 degrees.
Cost will decrease and coolness will increase-
The rays in the sun called IR and UV are responsible for the heat. White color reflects 80 percent of the light. But can’t reflect IR and UV rays. But now special inventions have been made to reflect these rays also. Which is known as polymer.
special chemical low temperature
Many different inventions have been made to enhance cooling with . The temperature is reduced by 5 degrees by preparing a reflective surface of silicon dioxide and hafnium dioxide. Similarly, using a mixture of polymers and silver reduced water in air conditioning by 21 percent, and a film made of glass beads reduced surface temperatures by 10 degrees.
Special polymer developed in Australia
A special polymer developed in Australia can keep roofs 3 to 6 degrees cooler. Physicists at the University of Colombo used a combination of plastic and air to create a highly reflective material. While working on a polymer, it was found that under certain conditions the material turns white after drying. When viewed with the help of a microscope, it was found that the dry film had air sacs attached to each other. which reflects more light. Which is reinforced with the help of polymers.
The research eventually led to a polymer called PVDF-HFP, which Reflects 99 percent of the light. A special color was prepared by mixing it with acetone. Acetone evaporates when the ceiling is painted. The water droplets then get trapped in the polymer. Eventually the superheated water also evaporated. And a surface filled with air-holes is prepared. Which reflects 99.6 percent of the light.
AC feeling will be available even in the afternoon.
According to the report prepared at the end of the research, despite being colored with polymers, it can remain cold up to 6 degrees in the afternoon. Polymers reduce home cooling costs by up to 15 percent in the summer. But this paint is five times more expensive than the acrylic paint used today. The big question about this chemical is whether it will be commercially useful or whether conventional methods will work.
