Heating furnace thermal insulation material nano thermal insulation board has good thermal insulation effect

Thermal insulation materials are important high-temperature engineering materials, which are of great significance not only to the iron and steel industry, but also to the thermal insulation and energy efficiency improvement of other high-temperature devices
High performance thermal insulation materials need to have the properties of high-efficiency thermal insulation, light weight, high strength and chemical corrosion resistance

Nano thermal insulation board, as a new type of thermal insulation material, has excellent performance

First, the thermal conductivity is low
Nano thermal insulation board adopts light inorganic nano SiO2 and ceramic fiber with low thermal conductivity as raw materials, and its thermal insulation performance is about 4 ~ 6 times better than that of traditional thermal insulation materials

Secondly, nano insulation board has the characteristics of high fire resistance
Because the service life of the nano thermal insulation layer is high, it will not affect the service life of the original thermal insulation layer

Then, the construction is simple and cost-effective
Jinshi nano hard board can be cut at will, flexible board can be bent, and the construction performance is good

The reason for the good thermal insulation performance of nano insulation board is that the size effect of nano plate is small, the particle size is less than 20 nm, which prolongs the heat conduction path, and the porosity of nano plate is less than 50 nm, which is less than the free movement of air molecules
Therefore, there is no convolution in the product, which hinders the convective heat transfer; Adding shading agent to the nano plate can reflect the heat back to the insulation object and reduce the heat loss

The thermal conductivity of nano thermal insulation board is much lower than that of ceramic fiber needle punched blanket, and even lower than that of static air
However, the temperature resistance of nano thermal insulation board is not as high as that of ceramic fiber cotton
The temperature resistance of nano thermal insulation board can reach about 1100 ℃, but the temperature resistance of ceramic fiber cotton can reach 1200-1300 ℃
The thermal insulation effect of nano thermal insulation board is about 5 times that of traditional thermal insulation cotton, In the current industry, ladle and molten iron ladle are mainly used
They not only have good thermal insulation effect, but also reduce the thermal insulation thickness, which can save a lot of costs for enterprises
At present, the popularity of nano thermal insulation board has been increasingly recognized by enterprises
Of course, these are all expressed with accurate data
