2000w 2500w half white coated IR halogen heat lamps for pet bottle blowing machine
Halogen infrared heating lamps play an important role in bottle blowing machines and have many advantages. The following is a detailed introduction:
1. 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.
2. 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 ensuring the quality of the blown bottles, as it can avoid problems such as the bottles being too thin or too thick in some areas, inconsistent transparency, and ensure the strength and appearance quality of the bottles.
