What exactly is the method of infrared lamp Paint drying

Infrared lamp paint drying is to use a light source that can emit energy in a very narrow wavelength range to heat the coating film that can absorb radiation in this wavelength range. Organic molecules in the coating absorb energy, prompting molecular atoms or groups to vibrate or rotate, thereby increasing the energy inside the substance, inducing physical and chemical changes in the substance, and drying the coating.

At present, infrared drying technology usually adopts infrared drying, which can penetrate into the interior of the coating film, increase the internal temperature of the coating film, and the internal temperature of the coating film is higher than the surface, so that the thermal diffusion of the coating film forms a temperature gradient from the inside to the outside.
Infrared lamp Paint drying is operating while there is a moisture gradient inside the coating film, which causes moisture to move. The interior with more water content gradually diffuses to the outside with less water content, which is consistent with the direction of thermal diffusion, thus accelerating drying process.
