The development of the machinery manufacturing industry will also drive the rapid development of China's industrial heating industry, providing a broad space for the development of China's heat treatment industry. The industry has broad development prospects. In industry, the nano-infrared electric heating coil itself becomes a far-infrared radiation heat source, and because of the increase in its surface temperature, the temperature gradient increases, the thermal energy conduction intensity of the heated object is enhanced, and the heat absorption capacity is greatly improved. The direct effect of converting radiant heat energy into far-infrared heat energy through electric heating coatings is: increasing the temperature of the heated object, reducing the temperature of moisture loss, enhancing the heat absorption rate of the heated object, reducing heat loss, and achieving the purpose of energy saving.
