Infrared heating tubes have many important applications in the glass industry, as follows:
Glass annealing:
Principle: Glass undergoes high-temperature processing during the production process, and there is a large internal stress. If annealing is not performed, glass products may break due to stress release during subsequent use or processing. Infrared heating tubes can provide uniform and gentle heat, allowing the glass to cool slowly within a certain temperature range, thereby eliminating internal stress. For example, in the production of flat glass, the formed glass will pass through an annealing furnace equipped with infrared heating tubes and anneal under precise temperature control.
Advantages: The heating method of quartz glass infrared halogen heating heat lamp is radiation heating, and the heat transfer is direct and uniform, which can ensure that the temperature of the glass changes smoothly during the annealing process and avoid new stresses caused by uneven temperature. Compared with traditional annealing methods, infrared annealing can improve the quality and stability of glass and reduce the scrap rate.
Glass coating drying:
Principle: In order to increase the functionality of glass, such as improving the wear resistance, UV resistance, and thermal insulation performance of glass, it is often necessary to apply a special coating on the surface of the glass. After the coating is applied, the coating needs to be dried and cured so that it is firmly attached to the glass surface. Infrared heating tubes can quickly provide heat to evaporate the solvent or water in the coating quickly, thereby achieving drying and curing of the coating.
Advantages: Infrared heating can quickly heat up, greatly shortening the drying time and improving production efficiency. At the same time, due to the penetrability of infrared rays, the coating can be heated both inside and on the surface at the same time, ensuring that the coating is dried evenly, improving the quality and performance of the coating. For example, in the production of automotive glass, in order to add heat insulation to the glass, a heat insulation coating is applied to the surface of the glass, and then an infra red IR halogen heating lamp is used for drying.
Glass hot bending:
Principle: Hot bending glass is to heat the flat glass to near the softening temperature, and then bend it into the desired shape through a mold or other means. Infrared heating tubes can provide precise heat control, so that the glass reaches the softening temperature in a specific area for bending processing.
Advantages:twin tube infrared halogen heating lamp can be flexibly arranged and adjusted according to the shape and bending requirements of the glass to achieve local heating of the glass. This local heating method can reduce energy consumption and also prevent excessive deformation or defects of glass during heating. For example, in the production of architectural decorative glass, infrared heating tubes are often used to bend glass to make glass decorations of various shapes, such as curved glass curtain walls, circular glass partitions, etc.
Glass cutting and splintering:
Principle: Using the principle of thermal expansion and contraction of infrared rays, the energy of the Infrared Quartz Heating Halogen Lamp is focused on a specific area on the surface of the glass, so that the temperature of the glass in this area rises and thermal stress is generated. When the thermal stress reaches a certain level, the glass will break at a predetermined position, thereby achieving glass cutting and splintering.
Advantages: Compared with traditional mechanical cutting methods, infrared cutting and splintering technology has higher precision and efficiency, can cut more complex shapes, and will not cause mechanical damage to the glass. For example, in the production of electronic glass, in order to cut the glass into specific sizes and shapes, quartz glass ir infrared heater heat lamps are used for cutting and splintering.
Glass welding:
Principle: Glass welding is required in the repair of glass products or the connection of certain special glass structures.e infrared heater halogen glass replacement parts can provide a high-temperature heat source to melt the welding part of the glass, and then achieve welding during the cooling process.
Advantages: Infrared welding can quickly increase the temperature of the welding part, and can accurately control the welding temperature and welding time, thereby ensuring the quality and strength of the welding. At the same time, due to the non-contact heating method of infrared, it will not affect other parts of the glass, avoiding problems such as deformation or cracking of the glass caused by local overheating.
