When, the construction material of the tool pyroelecthc properties is also gradually increasing the screening ability of magnetic field, plane wave and microwave, illustrates institute
The electromagnetic shielding capability for stating the construction material of tool pyroelecthc properties increases with the increase of the graphite worm density.
Comparative example 5, embodiment 6 and embodiment 7 it is known that when the mass fraction of the land plaster is increased,
Mass fraction equivalent to the graphite worm in the construction material of the tool pyroelecthc properties declines, the corresponding tool thermoelectricity
The construction material of characteristic is also gradually reduced to the screening ability of magnetic field, plane wave and microwave.This described land plaster quality of explanation
The increase of fraction be unfavorable for it is described tool pyroelecthc properties construction material electromagnetic shielding, reduce its to magnetic field, plane wave and
The electromagnetic shielding capability of microwave.
Compared to prior art, in the construction material of tool pyroelecthc properties of the present invention, using graphite worm, the graphite is compacted
The density of worm is smaller, only 0.005g/cm3~0.05g/cm3, specific surface area is big, thus in construction material, it is easier to formed
Thermal conductivity network.In the case of with mass ratio identical shared by existing graphite particle, the building of the tool pyroelecthc properties
Materials conductive heat-conducting effect is more preferably;In other words, identical heat conduction and shielding can be reached with the graphite worm of smaller scale
Effect, while also reducing production cost, tool has an unexpected effect.In addition, the construction material of the tool pyroelecthc properties
Remain original mechanical property.The building board being prepared from by the construction material of the tool pyroelecthc properties has excellent leading
