Schematic diagram of infrared light reflection

Cars have now become an indispensable main means of transportation in our lives, and bumps will occur more or less during travel, so the automotive paint industry has emerged.

The ordinary infrared electric heating tube or electric heating plate used in the traditional car paint process uses a metal heating element as the heating carrier. The electric heating conversion efficiency is about 70%, the electric heating radiation conversion efficiency is about 40%, and the infrared wavelength radiation intensity is low. Most of the metal heating elements of ordinary infrared heating tubes or heating plates are exposed to the air. With long-term use, the metal heating elements begin to slowly oxidize, resulting in an increase in resistance and power attenuation, causing the room temperature to rise more and more time Long, the paint effect is getting worse and worse.

The infrared lacquer room mainly makes full use of the characteristics of infrared, which has reflectivity, permeability and resonance. Due to the superior reflectivity of infrared rays, infrared rays can be reflected everywhere in the space, so that the object to be dried can be exposed to infrared radiation at any time; the permeability of infrared rays can effectively penetrate into the paint layer, which can be achieved from the innermost The layer is gradually dried to the outer layer, and the resonance performance effectively generates resonance and friction with the molecules of the object to be baked, effectively increasing the drying temperature and the temperature of the link, so as to achieve the purpose of rapid drying. It uses pure black body material carbon fiber as the heating carrier, the electrothermal conversion efficiency is more than 95%, and there is very little visible light in the electrothermal conversion process.

Infrared car paint booth

The conversion efficiency of electric heating radiation is more than 70%; the infrared wavelength is 1.5-10 microns, which has excellent matching with the drying wavelength of the paint; the carbon fiber infrared quartz heating tube is compared with the infrared radiation of the metal heating element, and the organic matter absorption wavelength and infrared radiation intensity are increased respectively More than 30%. Due to the strong permeability of infrared radiation, the water and solvent in the paint will evaporate first due to the matching of the wavelength during the baking process, and the dry paint layer will not generate bubbles due to the evaporation of the water and solvent inside. And small holes, so the effect of baking is even better, can effectively improve the surface quality of the paint, increase the adhesion of the paint film, higher strength, brighter brightness, and better toughness. Long service life: The continuous service life of carbon fiber infrared lamps is up to 10,000 hours.

The use of infrared heating in the car paint booth has the following advantages:
1. With penetrating power, it can be heated inside and outside at the same time to quickly achieve the purpose of drying.
2. There is no need for heat transfer, and the heat efficiency is good.
3. It can also be heated locally to save energy.
4. The design breaks through the idea of traditional paint baking room, reduces pipelines and heating mechanical systems, and is simple and easy to combine space, installation and maintenance, greatly reduces hidden troubles and avoids the huge energy consumption of ordinary electric heating paint booths, and saves costs .
5. The heating process is environmentally friendly and has no pollution, no electromagnetic radiation, clean, no noise, and no secondary pollution.
6. The temperature control is easy, and the temperature rises quickly, and the safety is high.
