How Far-infrared Ceramic Heaters Work?
The working principle of the far-infrared ceramic heater Short-wave infrared radiation is also called near-infrared radiation. Medium and long waves are also called far-infrared radiation. Due to the extremely small thermal inertia and high thermal efficiency of infrared radiation, the infrared radiation currently used by ceramic heating plates for industrial purposes is mainly short waves with a wavelength of about 0.76 to 1.6um, medium waves with a wavelength of about 1.6 to 4um, and long waves with a wavelength greater than 4um. The far-infrared ceramic heater uses short-wave and medium-wave infrared radiation technology to heat the workpiece with high density, high energy, and high intensity, in order to improve the heating quality, shorten the heating time, save heating energy, reduce investment quota, and reduce environmental pollution. The purpose of this is what the industry calls high-infrared radiant heating technology.
The working principle of the far-infrared ceramic heater is that when the frequency is close to the natural frequency of the molecular motion in the heated object, electromagnetic waves are generated by the infrared heating tube. It causes the resonance of the molecules in the object, and the thermal energy generated by friction occurs to achieve the purpose of heating. When the frequency is close to the natural frequency of the molecular motion in the heated object, the infrared heating tube generates electromagnetic waves. It can cause the resonance of the molecules in the object, and the thermal energy generated by friction occurs to achieve the purpose of heating. In order to apply to different heating objects, the natural frequencies of different heating materials are different. By changing the data composition and the winding method of the heating wire, infrared radiation of different wavelengths can occur, so that the electromagnetic wave frequency of the infrared heating tube and the natural frequency of the molecular motion in the heated object can be maximized to achieve the maximum heating effect.
If the ceramic electric heating tube breaks suddenly during the heating process, will it continue to be energized to cause leakage and cause a safety accident?
Anyone who has used ceramic electric heating pipes will know that ceramic electric heating pipes are more fragile than others. If they are subject to violent impact, they may break, so many customers will worry that if they are cracked, electric leakage may occur. In fact, the material of the ceramic electric heating pipe is metal tungsten covered with aluminum oxide on the surface. Under normal circumstances, the heating area of the pipe is completely insulated except for the lead wire area which is a metal wire. This has more advantages. Because of the particularity of the heating circuit of the ceramic electric heating tube, after the electric heating tube is broken, the power supply operation will be stopped. When the tube is heated by contact with water, it can better avoid potential safety hazards caused by leakage.
