The following eight points:
1. The wavelength of infrared radiation is controlled at about 0.76-25μm. Users can choose heating tubes with different wavelengths according to the material and physical characteristics of the heated workpiece, or choose heating tubes with different wavelengths to form the best combination scheme.
2. The thermal efficiency of the heating tube is very high, and the infrared radiation efficiency can reach more than 86% in a certain wavelength and direction.
3. The thermal inertia of the infrared radiation heating tube is extremely small. It can reach about 50% of the rated power in 1 to 2 seconds after power-on, and it can run at full power after about 2 to 4 seconds, and the heating and cooling are rapid and accurate.
4. The heating tube itself is small in size, but the power is very high. The rated power of a single heating tube can be more than 6000w, and it can be easily made into high-infrared heating equipment such as plate heaters, hot air heaters, ovens, and drying tunnels. .
5. According to customer needs, a directional reflection layer containing precious metals such as gold and titanium or inorganic substances can be sprayed on a certain part of the outer wall of the heating tube, which can greatly improve the heating efficiency and reduce the temperature of the reflector or insulation board.
6. The cost of the heating tube is low and the service life is long. The continuous service life of the heating tube below 3000w under rated conditions exceeds 5000 hours, and the service life of the heating tube above 3000w exceeds 3000 hours, which can greatly reduce the operating cost. Supply heating tube, red glass heating tube, ruby quartz heating tube.
7. Various heating equipments composed of infrared radiation heating tubes can realize automatic temperature control through temperature controllers, thyristor AC power regulators or voltage regulators. Because of its small thermal inertia, the temperature control is fast and accurate.
8. Due to high-energy and high-density radiation, the time required for heating and the length of the drying tunnel are greatly shortened, which saves the space occupied by the equipment and directly reduces the user's investment in equipment and workshops. At the same time, due to the high thermal efficiency, the electric energy can be greatly saved and the production cost can be reduced.
