(Summary description)Infrared radiation is part of the electromagnetic spectrum, situated between visible light and microwaves, with a wavelength range of approximately 0.75 micrometers to 1000 micrometers. It is divided into near-infrared (0.75-1.4 micrometers), mid-infrared (1.4-4 micrometers), and far-infrared (4-1000 micrometers). Below is the basic principle of infrared radiation and its application in the heating process.

Infrared radiation is part of the electromagnetic spectrum, situated between visible light and microwaves, with a wavelength range of approximately 0.75 micrometers to 1000 micrometers. It is divided into near-infrared (0.75-1.4 micrometers), mid-infrared (1.4-4 micrometers), and far-infrared (4-1000 micrometers). Below is the basic principle of infrared radiation and its application in the heating process.
Infrared radiation is a form of thermal radiation:
- The surface of the object absorbs infrared radiation energy, causing the surface temperature to rise. The absorption efficiency depends on the material properties and surface characteristics of the object.
- The absorbed infrared radiation energy is converted into heat energy, causing molecules and atoms to move vigorously, resulting in a temperature increase.
- Heat energy is conducted from the surface of the object to the inside, making the entire object’s temperature uniformly rise.
The application of high infrared radiation heating technology has brought revolutionary changes to the coating of aluminum profiles, especially with quartz infrared heating lamps playing a crucial role in this field. The rapid curing process of aluminum profile coatings can be divided into two stages:
- Diffusion Stage: In this stage, thermal radiation penetrates the coating, heating the substrate and the coating, promoting the diffusion and removal of volatile components. The energy from infrared radiation causes the solvent in the coating to evaporate quickly, reducing the moisture content in the coating.
- Curing Stage: This stage involves the radiation acting on the chemical molecules of the coating to cure it. This stage requires relatively high temperatures, and the reaction rate determines the speed of the drying process. By matching the appropriate infrared radiation wavelength, it can act directly on the adhesive to achieve rapid drying and curing.
Quartz infrared heating lamps greatly improve the potential for reducing the curing time of aluminum profiles. To achieve rapid curing, the following conditions must be met:
- Uniform Temperature Distribution: During the curing process, a uniform temperature distribution in the upper, middle, and lower parts of the workpiece is crucial.
- Instant Heat Energy Supply: Regardless of the size and mass of the workpiece, quartz infrared heating lamps can provide a large amount of heat energy instantaneously.
- Sufficiently High Surface Temperature: The surface of the workpiece must reach a sufficiently high temperature to achieve rapid curing.
Within a certain temperature range, the curing effect is proportional to the product of temperature and time. Therefore, the modular integrated heating produced by quartz infrared heating lamps can significantly increase the temperature to shorten the curing time.
