Application of Infrared Heating Technology in the Coating Industry

Feb. 15, 2020

In the coating industry, the speed and quality of surface curing and drying are constantly increasing, so the coating drying process becomes very critical. IR Heating Tube is designed to directly heat objects. It is controllable, accurate, efficient, hygienic and environmentally friendly. Therefore, it is highly respected in the surface treatment industry. Medical, plastic, glass, electronics and other industries. Infrared heating is a type of radiant heating. The infrared light emitted by the infrared radiator (light source) is absorbed by the material in the form of molecular (atomic) resonance, so as to achieve the purpose of heating the object. Infrared heating is a highly efficient method of heating, drying and curing by directly and directly heating the object surface and a certain depth with a matching wavelength and selective penetration ability. The Carbon Infrared Heater Manufacturer introduces the application of infrared heating technology in the coating industry.

Hot blast stoves that are traditionally used transfer heat through an air medium. Because convection heating is used, the air itself must be heated first, so the heating speed by hot air is very slow. Infrared is used to absorb the infrared electromagnetic radiation to be heated by the object being heated. It is a non-contact heating method, which avoids any medium in the heating process and also avoids energy loss. Therefore, compared with the traditional hot blast stove, infrared heating effectively shortens the heating time.

In order to control the furnace temperature of a hot blast stove, the temperature of the entire air in the furnace must be changed. Each time a product is replaced, a hot blast stove can only slowly and difficultly achieve the required temperature profile or different baking temperature again, because the hot blast stove needs time to adjust to a new temperature. The infrared system does not need to contact the medium, but transmits heat through infrared electromagnetic waves, so it can be efficiently adjusted to the required temperature, and avoids overheating of the heated material flexibly. Infrared heating technology also makes it possible to quickly change different baking temperatures and different types of paint.

The traditional hot air heating heat transfer is gradually transmitted from the indication of the heated object to the inside, so the temperature distribution inside the heated object is uneven. Infrared rays have the ability to penetrate, and can heat the heated object and the indicating coating at the same time, so the temperature inside the heated object and the surface layer is relatively uniform, which avoids skin peeling or blisters. The dried surface is smooth and beautiful. , Increase the quality of the surface coating.

In addition, because infrared radiation can only be applied to local areas, the coating can be directly heated, while reducing the heating of objects that do not need to be heated, such as furnace air, furnace wall, and furnace perimeter. This saves energy and therefore greatly Reduced costs and a more comfortable working environment. Because infrared heat transfer is fast and efficient, in most cases the length of the hot blast stove can be greatly shortened, space is saved, and installation is relatively easy.

The above is the application of infrared heating technology introduced by Infrared Heating Tube Supplier in the coating industry.
