The heating speed of infrared heating tubes varies due to many factors, and generally has the following characteristics:
Different types of heating speed:
Short-wave infrared heating tubes: The heating and cooling speed is quite fast, usually 1-3 seconds can reach a high power output, flexible control, long service life, generally can reach more than 5000 hours, often used for rapid heating in printing, plastics and other fields.
Medium-wave infrared heating tubes: can transfer a large amount of energy in a short time, with strong targeting, can quickly heat the surface of objects, and for glass, plastic, water and other materials, it is easier to absorb medium-wave radiation and convert it into heat.
Long-wave infrared heating tubes: fast heating speed, uniform heating, small thermal inertia, only 1-3 minutes to reach the constant temperature of the component, high electrical energy radiation conversion efficiency, up to 60%-75%, no explosion in cold and hot, energy-saving and long service life.
Factors affecting the heating speed:
Heating tube power: The greater the power, the more heat generated per unit time, and the faster the heating speed. For example, under the same conditions, a 1000W infrared heating tube heats up faster than a 500W heating tube.
Heating tube size: Generally speaking, heating tubes with smaller diameters and shorter lengths have relatively smaller heat capacity and heat up faster.
Properties of the heated object: If the heated object is a good thermal conductor, such as metal, the heat of the heating tube can be quickly absorbed and the heating rate may be relatively stable; but if it is a poor thermal conductor, such as ceramics, the temperature of the heating tube may rise rapidly first and then slowly transfer to the ceramics.
Usage environment: In an environment with low ambient temperature and good ventilation, heat dissipation is fast and the heating rate may slow down; in a relatively closed environment with good insulation, the heating rate will be faster
