The microwave perlite insulation board drying equipment developed and produced by Zhengzhou Dingli is a new type of large-scale continuous microwave drying equipment, which has the advantages of high efficiency, energy saving and environmental protection in the perlite insulation board drying industry. Tunnel-type perlite board drying microwave equipment dries evenly without deformation or cracking. Because microwaves act on both internal and external parts of the material at the same time, heating is uniform, so the microwave-treated materials are dried evenly and thoroughly, improving product quality. The surface will not harden, improve toughness, and ensure that it will not crack, deform, discolor, etc.
Microwaves are electromagnetic waves with a frequency of 300 MHz to 300 GHz. Water molecules in the heated medium material are polar molecules. Under the action of rapidly changing high-frequency magnetic fields, their polar orientation will change with the external electric field. The changes cause the movement of molecules and mutual friction effects. At this time, the field energy of the microwave field is converted into thermal energy in the medium, which increases the temperature of the material and produces a series of physical and chemical processes of heating and puffing to achieve the purpose of microwave drying and heating sterilization.
