Principle and characteristics of ceramic heating plate
1. The principle of infrared heating:
The heat transfer form of infrared is radiant heat transfer, and the energy is transferred by electromagnetic waves. When far-infrared rays are irradiated to the heated object, part of the rays are reflected back, and part of the rays are penetrated. When the emitted far-infrared wavelength is the same as the absorption wavelength of the heated object, the heated object absorbs the far-infrared. At this time, the molecules and atoms inside the object "resonate"-produce strong vibration and rotation, and vibration and rotation cause The temperature of the object rises to achieve the purpose of heating.
Infrared radiation refers to the emission and transmission (propagation) of electromagnetic waves with a spectrum between 0.7um and 80um. The emission and transmission are accompanied by obvious and directional energy transmission. The transmission of energy does not require an exchange medium, and it can be transmitted even in a vacuum. . Infrared can be divided into short wave, medium wave and long wave according to the wavelength.
Aoneng brand infrared heater is a non-luminous (dark) radiant heater, which emits radiation in the 2-10um wavelength range of medium and long waves, and belongs to long wave heaters.

2. Characteristics of infrared heating:
1. It has penetrating power and can heat both inside and outside.
2. No need for heat transfer medium to transfer, good thermal efficiency.
3. It can be heated locally to save energy.
4. Provide a comfortable working environment.
5. Save the construction cost and space of the furnace body, and the assembly, installation and maintenance are simple and easy.
6. Clean heating process, no need of hot air, no secondary pollution.
7. Easy temperature control, rapid heating, and safer.
8. Small thermal inertia, no need to warm up the machine, saving manpower.
Because the infrared heater has the above-mentioned advantages, it is possible to obtain high-efficiency and high-uniform heating, and then it is accepted and applied in various fields at an astonishing rate of development.
