Home: As much attention is paid to building a house, the same attention is paid to painting the house. Then doing some kind of color work will make your house look very good. Now remove the AC and bring polymer, you will not feel hot in the house… In primitive times, insulation method was used to keep the house cool. So along with the natural environment, there was a feeling of coolness in the house. But with the development of technology, today AC is found in everyone's house. Press a switch and get instant relief from the heat. But now such colors are also being made which by painting on the house will make the house cool.
In countries where Suryanarayana is angry, white colour is especially seen on houses. So it protects from the sun. 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 can reduce the temperature by 6 degrees.
Cost will decrease and cooling will increase –
The rays called IR and UV in the sun are responsible for heat. White color reflects 80 percent of the light. But it cannot reflect IR and UV rays. But now special inventions have been made to reflect these rays as well. Which is known as polymer.
with special chemically low temperature
Many different inventions have been made to increase cooling. Temperatures have been reduced by 5 degrees by preparing reflective surfaces of silicon dioxide and hafnium dioxide. Similarly, water in air conditioning was reduced by 21 percent using a mixture of polymers and silver and a film made of glass beads reduced surface temperatures by 10 degrees.
Special polymers developed in Australia –
A special polymer developed in Australia can keep roofs cool by 3 to 6 degrees. 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 circumstances, this material turns white after drying. When observed with the help of a microscope, it was found that air voids connected to each other have formed in the dried film. Which reflects more light. Which is strengthened with the help of polymer.
The research eventually led to a polymer called PVDF-HFP, which reflects 99 percent of light. It was mixed with acetone to create a special paint. When the ceiling was painted, the acetone evaporated. Then water droplets became trapped in the polymer. Eventually the superheated water also evaporated, leaving a surface full of air pores that reflected 99.6 percent of light.
You will get the feeling of AC even in the afternoon-
According to the report prepared at the end of the research, despite being painted with polymers, it can remain cool by up to 6 degrees even in the afternoon. Polymers reduce the cost of cooling the house by 15 percent in summer. But this paint is five times more expensive than the acrylic paint used nowadays. In such a situation, the big question about this chemical is whether it will be commercially useful or traditional methods will work.
