Infrared heating lamps are used in the glass industry: Application in the glass annealing processRelieve stress: During the glass production process, glass products will generate internal stress after rapid cooling and other processes. Infrared heating lamps can provide uniform heat to slowly heat the glass to the annealing temperature. For example, for flat glass with a thickness of 5-10mm, the annealing temperature is generally between 500-600℃. Infrared heating lamps can accurately control this temperature range, allowing the stress inside the glass to be evenly released, thereby improving the strength and stability of the glass and preventing the glass from breaking during subsequent use.Prevent deformation: Since the infrared tungsten heat lamp heats evenly, the local overheating of the glass can be effectively avoided during the annealing process. Compared with traditional heating methods, such as gas heating, quartz infrared heater tubes can better control the heat distribution. For example, in the annealing of optical lenses, the use of replacement infrared halogen lamps can ensure the shape accuracy of the lenses and meet the requirements of high-precision optical instruments.Assistance in the glass forming processPreheating raw materials: Infrared heating lamps can be used to preheat glass raw materials before the forming operation after the glass is melted. Glass raw materials are easier to form at the right temperature. For example, when blowing glassware, preheating the glass blank to the softening temperature throughshortwave infrared heating curing lamp can make the glass easier to blow into the desired shape and reduce defects in the forming process, such as uneven wall thickness.Auxiliary thermoforming: For some special-shaped glass products, thermoforming processes are required. Infrared heating lamps can provide continuous heat during the thermoforming process to ensure that the glass maintains good plasticity during the forming process. For example, when manufacturing glass products with complex curved surfaces such as car windshields,halogen heating bulbs can help the glass fit the mold better and improve the forming quality.Role in glass deep processingTempered glass processing: In the production process of tempered glass, halogen lamp far infrared quartz tubes can be used to heat the glass to the tempering temperature (usually around 620-640℃). Its rapid heating characteristics can improve production efficiency, and uniform heating can make the glass form uniform compressive stress during the tempering process, thereby enhancing the impact resistance of the glass. For example, after the effective heating of the infrared heating lamp, the strength of the tempered glass used in construction can reach several times that of ordinary glass, which greatly improves the safety of the glass.Glass coating pretreatment: Before the glass is coated, the glass surface needs to be cleaned and preheated. infrared halogen heating elements can be used to preheat the glass so that the coating material can better adhere to the glass surface. At the same time, the heating process can remove some water vapor and impurities on the glass surface and improve the quality of the coating. For example, in the sunscreen coating process of automotive glass, after using the industrial infrared heat lamp to preheat the glass, the adhesion of the coating is stronger, and the sunscreen effect of the coated glass is better.
