How to choose an infrared heating lamp suitable for different application scenarios?Industrial manufacturing scenarioMetal processingHeating power requirements: Metal materials generally require higher power for rapid heating. For example, for heat treatments such as quenching and annealing of metals such as steel, due to the high thermal conductivity of metals, a large energy input is required to quickly raise the temperature. The heating power is usually between tens of watts and hundreds of watts per square centimeter, depending on the size of the metal parts and the heating speed requirements.Wavelength selection: Metals have a wide range of infrared absorption wavelengths, but the absorption efficiency is relatively high in the near-infrared region (wavelength of about 0.76 – 1.4μm). Therefore, when choosing Quartz Infrared Halogen Heating Elements, lamps that emit near-infrared rays can be given priority to improve heating efficiency.Lamp shape and layout: If large metal plates are to be heated, long strips or square heating lamps may be more suitable, and an array layout can be used to ensure uniform heating of the metal surface; for irregularly shaped metal parts, Infrared Heating Quartz Lamp with adjustable angles or customized shapes can be selected to better fit the shape of the parts for heating.Plastic processingHeating power requirements: Different types of plastics have different softening temperatures and thermal conductivity. The heating power should be determined according to the specific type of plastic and the processing technology. For example, when PET plastic is used for bottle blowing, the heating power is generally between a few watts and more than ten watts per square centimeter to heat the plastic bottle blank to the appropriate blowing temperature (about 100-120℃).Wavelength selection: Plastics have good absorption characteristics for infrared rays of specific wavelengths. For example, PET plastics absorb infrared rays with wavelengths of about 2-3μm better, while PP plastics absorb infrared rays with wavelengths of about 3-4μm better. Therefore, in plastic processing, heating lamps with matching wavelengths should be selected according to the plastic material.Lamp shape and layout: For heating plastic films and sheets, flat or ring-shaped Infrared Halogen Heating Elements are more suitable. In plastic bottle blowing machines, ring-shaped Halogen Infrared Heating Lamp can perform circumferential heating around the bottle blank to ensure uniform heating of the bottle blank; for heating plastic pipes, long strip Quartz Infrared Heating Elements can be arranged along the axial direction of the pipe to achieve uniform heating.Food processing scenariosBaked foodHeating power requirements: When baking bread, biscuits and other foods, moderate heating power is required to ensure that the surface of the food can quickly form a golden color and a crispy crust, while not leaving the inside undercooked. Generally speaking, the heating power is more appropriate between a few watts and more than ten watts per square centimeter.Wavelength selection: The moisture, sugars, proteins and other ingredients in food absorb infrared rays. Infrared rays with a wavelength of about 2.5-3.5μm can be well absorbed by food. When used for baking, the inside and surface of the food can be heated at the same time, improving the baking effect.Lamp shape and layout: In the oven, flat Electric Infrared Heat Lamp are usually used, installed at the top and bottom of the oven, so that the food can be heated from both the top and bottom directions, so that the food is heated evenly. Some advanced ovens also install small heating lamps on the side to assist in heating the side of the food.Food dryingHeating power requirements: Food drying requires rapid evaporation of the moisture in the food, which generally requires a higher heating power, usually between more than ten watts and tens of watts per square centimeter, depending on the moisture content of the food and the drying speed requirements.Wavelength selection: Water strongly absorbs infrared rays with a wavelength of about 2.5-3μm, so in the process of food drying, choosing a heating lamp that emits infrared rays in this wavelength range can efficiently remove moisture from the food.Lamp shape and layout: For batch drying of dried fruits and dried vegetables, multi-layer rack drying equipment can be used. The heating lamp is installed above or below each shelf, and the drying intensity is controlled by adjusting the distance between the lamp and the food. For drying block foods such as meat, a long strip or square heating lamp with a reflector can be used to focus the infrared rays on the food to improve the drying efficiency.Medical physiotherapy sceneLocal physiotherapyHeating power requirement: When performing local physiotherapy, such as joint pain, muscle strain, etc., in order to avoid scalding to the patient, the heating power should be moderate, generally within a few watts per square centimeter. This can ensure the safety of the patient while ensuring the treatment effect.Wavelength selection: Human tissue absorbs far infrared rays with a wavelength of 3-14μm well. Heating Infrared Bulbs in this band can penetrate into human tissue and promote blood circulation and metabolism. Therefore, in medical physiotherapy, heating lamps that emit far-infrared rays are usually chosen.Lamp shape and layout: Halogen Lamp Replacement Parts used for physiotherapy are usually designed in a shape that is easy to operate, such as handheld or adjustable angle lamps. The size of the infrared halogen heating lamp is generally small, and it can accurately radiate Infrared Quartz Heat Lamp to the parts of the patient that need treatment, such as joints, waist, etc.
