Carbon fiber heating lamps are used for car paint: Working principleCarbon fiber Car drying paint heating lamps mainly use carbon fiber heating wires to generate heat. Carbon fiber is a high-performance fiber with a carbon content of more than 90% and good conductivity. When current passes through the carbon fiber heating wire, due to the resistance of the carbon fiber itself, electrical energy is quickly converted into thermal energy. At the same time, carbon fiber radiates infrared rays outward during heating. During the car paint baking process, the wavelength range of infrared rays can match the vibration frequency of paint molecules. After the paint molecules absorb the energy of infrared rays, the vibration and rotation of the molecules intensify, which increases the internal energy of the paint and the temperature. This heating method is carried out from the inside and outside of the paint at the same time, which can quickly evaporate the solvent in the paint and promote the curing of the paint. AdvantagesEfficient heating and fast curing: Carbon fiber car heating element have high thermal conversion efficiency and can quickly convert electrical energy into thermal energy and radiate it. In car paint baking, this means that the baking time can be greatly shortened. For example, traditional hot air paint baking may take several hours to complete the curing process, while carbon fiber heating lamps can shorten the time to tens of minutes or even shorter. This can significantly improve production efficiency for automobile manufacturers. Good temperature uniformity: Through reasonable lamp layout and reflector design, carbon fiber car halogen bulb can make the temperature distribution in the paint room more uniform. In the process of car body painting, uniform temperature is one of the key factors to ensure the quality of paint. It can make the paint dry and solidify evenly on the entire surface of the car body, avoiding quality problems such as local over-thickness or over-thinness, inconsistent colors, etc. Energy saving and environmental protection: Carbon fiber car body paint booth directly radiate infrared rays to the paint surface of the car body, without the need to heat a large amount of air first like hot air painting. This direct radiation heating method makes the energy loss relatively small, which can save energy by about 30% – 50% compared with traditional painting methods. At the same time, due to its fast heating speed, it reduces the operating time of the paint equipment and indirectly reduces energy consumption. Accurate temperature control: Carbon fiber car infrared heat lamps can accurately control the temperature by adjusting the input current or voltage. Different types of car paints have different requirements for paint temperature. For example, some high-performance car paints may need to be painted within a specific temperature range (such as 80-120℃). Carbon fiber car quartz lamp can accurately adjust the temperature according to the type of paint and the requirements of the paint, ensuring that the paint is dried and cured under the best temperature conditions. Application pointsLighting layout and distance adjustment: In the car paint room, the layout of carbon fiber heating lamps should be determined according to the shape and size of the car. Generally, multiple sets of lamps are used to illuminate the car from different angles to ensure that all parts of the car body, including the doors, hood, roof, etc., can receive sufficient infrared radiation. At the same time, pay attention to adjusting the distance between the heating lamp and the car body. If the distance is too close, the paint surface temperature may be too high, causing bubbling, sagging and other problems; if the distance is too far, the paint effect may be poor. It is generally recommended that the distance is between 30-80 cm, and the specific distance should be determined according to the power of the car oven spray booth painting heating lamp and the characteristics of the paint. Match the power and wavelength with the paint characteristics: Different brands and types of car paints have different absorption characteristics of infrared rays, so it is necessary to choose a carbon fiber car infrared heat tube with appropriate power and wavelength. For example, some paints with special additives or pigments may absorb infrared rays better in a specific wavelength range. When choosing a heating lamp, consider the composition of the paint and the requirements for the paint. Generally speaking, for high-performance, high-thickness automotive paints, higher-power heating lamps may be required to provide enough energy to penetrate the paint layer and cure it. Ventilation system coordination: During the automotive paint baking process, the solvents in the paint will evaporate. If these solvents accumulate in the paint booth, it may cause safety problems such as fire or explosion. Therefore, a good ventilation system is needed to promptly discharge the volatile solvents from the paint booth. The air volume and wind speed of the ventilation system should be determined according to the solvent content of the paint and the size of the paint booth.
