What role does mica play in microwave ovens?

1, which is used to prevent water or oil from splashing on the magnetron during food heating and play a protective role. Because there is no mica sheet, the connecting part of the waveguide will burn out due to moisture and carbon deposition, and the magnetron will be damaged if it is used for a long time. Mica can be penetrated by microwave, with high insulation, and will not undergo electromagnetic reaction or qualitative change due to the action of microwave.

2. Microwave oven refers to household or industrial appliances that use electromagnetic waves in microwave band to heat objects (mainly polar molecules, such as water). The microwave oven consists of power supply, magnetron, control circuit and cooking cavity. There is a rotatable agitator near the entrance of the cooking cavity. Because the agitator is a fan-shaped metal, it can reflect microwaves in all directions after rotation, so it can evenly distribute microwave energy in the cooking cavity, thus heating food. Its power range is generally 500- 1000 watt.
