There are many advantages of using halogen infrared heating tubes in printing dryers. The following is a detailed introduction:
High heating efficiency
Rapid heating: Halogen infrared heating tubes can quickly reach the working temperature in a short time. Generally, it only takes 20-30 seconds to output a large amount of heat, which greatly reduces the preheating time of the printing dryer and improves production efficiency.
Efficient conversion: 80% of electrical energy can be converted into thermal energy. Compared with traditional heating methods, the thermal conversion efficiency is higher, which can effectively save energy and reduce production costs.
Good drying effect
Uniform heating: The infrared rays it emits can be evenly radiated to the printing surface, so that the moisture or solvent in the printing material is evenly heated and evaporated, avoiding local overheating or uneven drying, thereby ensuring the quality and color consistency of the printing pattern.
Deep drying: Infrared rays have strong penetrating power and can penetrate deep into the printing material, so that the moisture can quickly diffuse and evaporate from the inside to the outside, achieving a more thorough drying effect and reducing the discoloration and fading of the printing pattern during subsequent processing or use. Precise temperature control
Small thermal inertia: The halogen infrared heating tube has a small thermal inertia and responds quickly to temperature changes. It can quickly adjust the heat output according to the temperature control system of the printing dryer to achieve precise temperature control, ensuring that the drying process is carried out within the set temperature range, which is conducive to improving the stability of printing quality.
Strong adjustability: The drying temperature can be accurately adjusted and stably controlled by adjusting the power of the heating tube or using advanced temperature control technology, such as PID control, to meet the drying temperature requirements of different printing materials and processes.
