Halogen infrared heating tubes play an important role in bottle blowing machines and have many advantages. The following is a detailed introduction:
Heating principle
Halogen infrared heating tubes heat the filaments through electric current. When the temperature of the filaments rises, the halogen gas in the tube is excited. The excited halogen atoms combine with the tungsten atoms evaporated from the filaments to form tungsten halides. The tungsten halides decompose in the high-temperature area near the filaments, and the tungsten atoms are redeposited on the filaments, extending the service life of the filaments. At the same time, the heat emitted by the filaments radiates outward in the form of infrared rays to heat the preforms in the bottle blowing machine.
Application advantages
Rapid heating: It can quickly increase the temperature of the preforms in a short time, greatly shortening the production cycle of bottle blowing. For example, in a high-speed bottle blowing production line, halogen infrared heating tubes can quickly heat the preforms to a temperature suitable for blow molding, improve production efficiency, and meet the needs of large-scale production.
Uniform heating: The infrared radiation emitted has good penetration and uniformity, which can make all parts of the preforms evenly heated. This is critical to ensure the quality of the blown bottles, and can avoid problems such as partial thinness or thickness, inconsistent transparency, etc., to ensure the strength and appearance quality of the bottles.
Precise temperature control: With the advanced temperature control system, the temperature of the heating tube can be accurately adjusted to meet the requirements of different material preforms and different blowing processes. For example, for PET preforms and PP preforms, the required heating temperature is different. By accurately controlling the temperature of the halogen infrared heating tube, it can ensure that the preforms of each material can get the best blowing effect.
Energy saving and environmental protection: It has a high electric heat conversion efficiency, which can convert most of the electrical energy into infrared heat energy, reducing energy waste. Compared with traditional heating methods, it can save a certain amount of energy costs while achieving the same heating effect, which meets the energy saving and environmental protection requirements of modern industry.
