Printing machines use medium-wave infrared heating lamps and short-wave quartz halogen heat lamp IR lamp, each with its own advantages. The specific effect depends on many factors. The following is a comparison of the two:
Heating speed:Short-wave quartz halogen infrared heater lamp: have a fairly high power, can reach full load working intensity within a few seconds, and have a very fast heating speed, which can quickly increase the temperature of the printing material. For some printing processes that require high heating speed and fast production rhythm, short-wave infrared halogen ir lamp are more advantageous.Medium-wave infrared heating lamp: The heating speed is slightly slower than that of short-wave heating lamps, but it can also heat the surface and thin layers of objects relatively quickly. In practical applications, the heating speed of medium-wave heating lamps can meet the needs of most printing processes.
Penetration ability:Short-wave infrared heating lamp halogen heater: have relatively weak penetration ability, and their energy is mainly concentrated on the surface of the object. For thinner printing materials or only surface heating is required, shortwave infrared heating lamp can quickly and effectively complete the heating task, but for thicker materials, the material may not be fully heated.Medium wave halogen heating bulbs: have a certain penetration ability, which can make the internal and surface molecules of the printing material absorb radiation energy at the same time, produce a self-heating effect, and make the overall temperature of the material rise quickly and evenly. For some printing processes that require the material to be dried or cured as a whole, the penetration of the medium-wave heating lamp can better ensure the heating effect.
Temperature uniformity:Short wave tungsten halogen lamp: Because its energy is concentrated on the surface, the surface temperature may be too high and the internal temperature may be low during the heating process, resulting in poor temperature uniformity. In order to ensure temperature uniformity, it may be necessary to increase the number of lamps or adjust the arrangement of lamps.Medium wave halogen bulb: The heating is relatively uniform, which can make all parts of the printing material get more consistent heating, thereby improving the quality and stability of printing.
Applicable materials:Short-wave heating lamp: Suitable for materials that are sensitive to temperature but do not require deep heating, such as some plastic films, paper, etc. For these materials, the rapid heating and surface heating capabilities of short wave industrial infrared heat lamp can prevent the material from being deformed or damaged by excessive heating.Medium Wave Infrared Heating Quartz Lamp: Suitable for various materials, especially for some materials that require overall heating and have high requirements for temperature uniformity, such as cloth, thick cardboard, etc., medium wave electric infrared heat lamp halogen lamp can provide better heating effects.
Energy consumption:Short wave halogen infrared heat lamp: It has high power and fast heating speed, but it may consume more energy during the heating process. If it works continuously for a long time, the energy consumption will be relatively high.Medium wave quartz infrared heating lamp: It is relatively energy-saving, can convert most of the electrical energy into heat energy, and has a high energy utilization rate. In long-term use, the energy consumption cost of medium wave Halogen quartz lamp halogen heat lamp may be lower.
