With the continuous advancement of science and technology, the process and equipment in industrial production are constantly innovating and improving. In many industrial productions, the heating link occupies an important position, such as the coating and drying of lithium battery pole pieces, and the heating of composite materials. wait. Material molding, thermoforming of automotive interior and exterior trims, molding of rubber and plastic parts in the electrical industry, etc., then, high-efficiency and energy-saving heating processes must be pursued by most manufacturing companies.

Our common heating method in industrial production is often hot air heating, that is, the heated air is used to transfer heat. In the heating process, air needs to be used as the medium. First, the air is heated to a certain temperature, and then the heat is transferred to the object to be heated by convection heat transfer. Therefore, the heating efficiency is low. The far-infrared heating method, taking the quartz infrared heater as an example, uses the thermal effect of the heated object to absorb infrared electromagnetic radiation to achieve the purpose of heating. It is a non-contact heating method, so any medium is avoided during the heating process, and energy loss is also avoided. Therefore, compared with traditional hot air heating, infrared heating effectively shortens the heating time of the heated object.

But it is undeniable that in the comparison of heating uniformity, because the hot air is heated through the air as the medium, when heating irregular products or products with shelter, the uniformity should optimize the infrared heating method. However, when heating regular objects or flat objects, infrared rays are superior to hot air in terms of heating efficiency, uniformity, and temperature control accuracy. In actual industrial production, hot air and infrared heating are used to work together in the heating process to realize the composite heating mode of hot air + infrared heating with complementary advantages.

In view of the advantages and disadvantages of infrared heating compared with hot air heating mentioned above, the quartz heater made in China has the advantages of fast effect, high thermal efficiency, uniform heating, long life, etc., which can escort the heating links in various industrial production and realize Energy efficient heating.
