Far-infrared heaters are devices that utilize far-infrared radiation for heating. Their working principle is based on the unique properties of far-infrared rays, which can directly act on the molecules and atoms inside an object, causing resonance effects and achieving rapid and uniform heating.

Specifically, when far-infrared rays are directed at the object to be heated, some of the rays are reflected back, while others are absorbed by the object. The absorbed far-infrared energy is converted into vibrational and rotational energy of the molecules and atoms within the object, causing these microscopic particles to resonate. This resonance effect intensifies the friction and collisions between molecules, generating heat and raising the object's temperature. Since this heating method starts from the inside of the object, it can achieve simultaneous heating both inside and out, significantly improving heating efficiency and uniformity.

Far-infrared heating technology has many advantages, such as strong penetration, fast heating speed, energy conservation, environmental protection, safety, and reliability. Therefore, it has been widely applied in various fields, such as thermoplastic material forming, greenhouse cultivation, and medical equipment.

The transmission distance of a far-infrared heating lamp refers to the appropriate distance that should be maintained between the heating lamp and the object being heated during use. This distance is crucial for ensuring safe and effective heating results.

Generally speaking, the recommended distance for using far-infrared heating lamps is between 40 and 60 centimeters. This distance ensures sufficient heating intensity while preventing the surface temperature of objects from getting too high due to being too close, thus avoiding the risk of burns or damage to the objects. Of course, the specific distance should also be adjusted based on the nature of the object being heated, heating requirements, and the power of the heating lamp.

When using far-infrared heating lamps, it is also necessary to pay attention to observing the heating condition of the object and adjust the distance between the heating lamp and the object in a timely manner to ensure uniform and safe heating. At the same time, it is important to avoid using the heating lamp continuously for a long time to prevent unnecessary damage to the object.
