Burnt bread for the insulation of houses and airplanes

Any cook will surely be disappointed when he sees that his bread is burnt, but not the researchers from the Harbin Polytechnic University, who were employed intentional burning of bakery products, to create a material known as peopleread.

The lightweight material serves as a heat insulator, the electromagnetic screen TV and an electric conductor, and it is, well, about as much as a loaf of bread.





In pirougleroda is nothing new. Because of its combination of low weight and great performance, the scientists showed him special interest for applications in the aerospace industry as insulating material, but currently, many methods of its production can be costly.

The idea of pirougleroda from food is also not new. Previously this material was made from edibles such as bananas and melon. But in those cases, it was difficult to accurately predict the final result, in order to produce foam with correctly specified characteristics for the job, as the size of the cells within the material were inconsistent.





The new method starts with a simple loaf of bread. But as soon as this loaf is produced and dried in a drying Cabinet for 18 hours at 80 ° C, after it is placed in a special oven, which uses argon gas to turn it into a carbon foam.

Scientists have discovered that the resulting foam has the same characteristics as other propertystate materials. Is durable, good temperature insulator with low weight, which provides shielding from electromagnetic waves. In addition, it is more fire-resistant than current materials used, so it can guarantee a good insulation for aircraft, space vehicles or even homes. This process is also, obviously, has a low cost, depending on your ingredients.





What is particularly interesting in this process is the fact that on the basis of the calculation of the amount of water and yeast that the researchers added to the dough, they were able to change the pores within the foam, meaning that the process can be adjustable. In other words, you can create peoplered with different pore sizes, depending on the different needs. published
