Mica heating pads have radiation, but it is thermal radiation, harmless to the human body.
Mica heating pads, metal armored tubes, carbon fiber far-infrared quartz heater, as long as the object can pass the voltage current, will be more or less thermal radiation, electromagnetic radiation. Of the above three appliances, mica heating pads relatively little radiation.
But pregnant women should be less close to the working electric iron stove, computers, microwave ovens, TVs and other household appliances, although electromagnetic radiation is very small, there is no harm to people, but high-power electrical appliances, pregnant women are best to stay away from.
Extended information:
Mica heaters utilize the mica plate (mica sheet) good insulation and its high temperature resistance, mica plate (sheet) as the backbone and insulation layer. With galvanized plate or stainless steel plate for support and protection, it can be made into various types of heating devices, such as plate, sheet, cylinder, cone, tube, circle, etc. The power can be designed up to 1000W. The power can be designed up to 1000W, and the temperature can be 600℃.
Stable performance, small thermal inertia, fast heating speed, in the working state and storage and transportation state, electrical performance are no change; and is a negative temperature coefficient of electric heating element, there is no inrush current brought about by the security risks.
When working, the infrared radiation is strong, and its far infrared wavelength is 2-15um, which is good for human health.
