New Aerogel Materials To Solve Heat Conduction Problems And Promote Industrial Energy Conservation And Consumption Reduction
New aerogel materials to solve heat conduction problems and promote industrial energy conservation and consumption reduction
A small piece of insulation felt, the front of more than 1000 degrees Celsius under the blue flame spray, the back can still be touched by hand, its excellent high temperature insulation performance attracted the attention of reporters
The new material has magical insulation because it is called aerogel.
Popularly speaking, aerogel is not a glue, but a material form, composed of more than 90% of the air and less than 10% of solid, and can withstand several thousand times the pressure of its own mass.
Aerogels were first prepared by hydrolytic water glass of DrKistler in Stanford University in 1931. However, due to complex technology and high cost, aerogels have not attracted enough attention since its advent.
It was only in the 80s of last century that Europe began to notice this new material. In 1993, aerogels were applied to space suits, spaceships, space shuttles, etc. in the United States. Aerogels were used in the "peace" space station and the American Mars Pathfinder explorer.
If the ultimate goal is achieved, the aerogel solid can even float in the air. Amazing. Aerogel, also known as "frozen smoke" or "blue smoke", is a nano porous insulation material, occupying the tip of the whole insulation Market in Pyramid.
The super insulating properties of aerogel insulation blanket is mainly due to their special nano porous structure. Because the diameter of the micro-pore formed in the material is smaller than the average free travel of the air molecules, the collision heat transfer between the molecules is restrained, and the thermal radiation shielding effect is added, the thermal conductivity of the material is lower than that of the static air at high temperature. The thermal insulation effect of the nano-thermal insulation material is four times that of the traditional thermal insulation material.
Compared with traditional thermal insulation materials, nano-thermal insulation materials can work in the temperature range of 1000 C for a long time, and can be used as thermal insulation layer. It has good thermal stability and can be used as insulation permanent layer. Its service life is more than 15 years. It can greatly reduce heat loss, reduce energy consumption and improve energy saving effect.
Although the unit price of the new insulation material is higher than that of the traditional insulation material, the overall cost is lower considering the service life and construction cost.
