Infrared heating lamps are used to dry paper coatings: Accelerate the drying processThe infrared rays emitted by Halogen Infrared Heating Bulb can be quickly absorbed by the solvent molecules in the paper coating. When IR Heating Lamps are irradiated to the paper coating, the water molecules or organic solvent molecules in the coating absorb the energy of the halogen quartz ir heating lamp, causing the movement of the molecules to intensify. For some paper processing production lines that require rapid drying, such as high-speed label printing production lines, the paper needs to be dried quickly after printing and coating before the next processing operation can be carried out. Infrared heating lamps can dry the coating in a short time, improving the production efficiency of the entire production line. Improve coating qualityInfrared heating can make the paper coating dry more evenly. Because short wave ir emitters can be evenly irradiated on the surface of the paper, the solvent in the coating can begin to evaporate at the same time in all parts. This avoids the situation where local drying is too fast or too slow, which may occur in traditional drying methods.
Moreover, the halogen heating lamp does not cause physical damage to the surface of the paper when drying the coating. It does not cause wrinkles in the paper or peeling of the coating like some high-speed hot air drying equipment. For some papers with high surface quality requirements, such as art paper and photo paper, infrared heating lamp halogen heater can maintain the flatness of the paper and the integrity of the coating while ensuring the drying of the coating. Energy saving and environmental protectionInfrared heating lamps have high energy utilization efficiency when drying paper coatings. It directly converts electrical energy into infrared radiation energy, and most of the energy can be absorbed by the coating for drying. In contrast, traditional hot air drying equipment needs to heat a large amount of air first, and a lot of energy will be lost to the surrounding environment in this process. At the same time, due to the fast drying speed of halogen heating bulb, the exposure time of paper coatings during the drying process is reduced, and the emission of volatile substances such as organic solvents is reduced. For some papers that use environmentally friendly coatings but still contain a small amount of volatile organic compounds (VOCs), the use of quartz electric heating lamp can effectively reduce the release of VOCs and meet environmental protection requirements. Accurate control of drying conditionsThe power and irradiation time of tungsten halogen lamp can be precisely adjusted. During the drying process of paper coatings, the drying temperature and time can be precisely controlled according to factors such as the type of paper, the composition and thickness of the coating.
