The purpose of using white coating in infrared heating lamps:
Reflect infrared rays and improve heating efficiency
The white coating is usually made of some materials that can reflect infrared rays efficiently. For example, the white coating of some ceramic materials, when the infrared heater replcement lamp is working, the infrared part emitted by it will radiate in all directions. The white coating can reflect the infrared rays radiated to the rear of the lamp body and other directions that do not need to be heated back to the heating area in front, just like a mirror reflects light. This can concentrate more infrared energy on the object that needs to be heated, thereby improving the heating efficiency. In industrial paint rooms and other environments,infrared heaters infrared heat lamp bulb with white coating can make the heat more effectively act on the surface of painted objects such as cars, and speed up the drying of the paint layer.
Enhance the uniformity of heat dissipation
The white coating can help infrared heaters with tungsten wire dissipate heat better. The thermal conductivity and thermal diffusion characteristics of white coating materials can make the heat more evenly distributed on the surface of the lamp body. This is because the white coating can adjust the temperature gradient on the surface of the infrared heating bulb body to a certain extent and avoid local overheating. For example, in the stretching process of plastic film, infrared heating emitter halogen lamps are needed to heat the plastic film to reach the appropriate stretching temperature. White-coated infrared heating lamps can provide uniform heat and prevent the film from cracking and other quality problems due to excessive local temperature.
Protect lamp body materials
The white coating can isolate the industrial heater tungsten heating lamp body from the external environment. Some lamp body materials may be corroded by substances such as oxygen and water vapor in the air under high temperature, thus affecting their performance and service life. The white coating can serve as a barrier to reduce the impact of these adverse factors on the lamp body. For example, in some outdoor heating equipment, the white coating can prevent impurities such as rain and dust from contacting the heating elements and other key components inside the lamp body, extending the outdoor service life of the infrared heating lamp.
Reduce light pollution and visual interference
White coating is less irritating to the human eye than some metallic coatings. In some workplaces, if the Infrared heating halogen heating lamp is not white-coated, its strong light may cause light pollution and affect the operator’s vision. The white coating can soften the light to a certain extent and reduce this visual interference. For example, in some food processing workshops, workers need to operate near the infrared heating lamp automotive. The white coating can make the workshop environment more comfortable and avoid the adverse effects of strong light on the workers’ vision.
