Problems solved by technology

[0002] Household appliances in people's daily life produce electromagnetic radiation. Electromagnetic radiation within a safe range will not cause harm to humans. However, as people's health awareness gradually improves, the requirements for the shielding effect of electrical electromagnetic radiation are also getting higher and higher. The method of preventing electromagnetic radiation in the prior art is mainly to spray a layer of anti-radiation coating on the outside of the electrical appliance, but electromagnetic radiation usually transmits heat in the form of electromagnetic waves, so the anti-radiation coating usually works in a high-heat environment for a long time. The surface is prone to chapping and falling off, which will affect the radiation protection effect of electrical appliances
