One of the most effective and fastest wayshardening of paint in industrial conditions is the method of surface treatment of the product by infrared radiation. For this, a special device is used - infrared drying. It is on its technical characteristics that the time during which the paint dries depends on the quality of the paintwork in general. What is drying is infrared and what is remarkable, you can find out here and now.
At the moment, there are several ways in which devices for industrial purposes quickly dry out after applying a certain layer of paint:
· Convective (with the help of a stream of hot air).
· Thermoradiation (using infrared radiation).
· Combined (combination of the first two).
Among them, the most effective, of course, isIR radiation. Infrared drying (IRT including) allows you to process almost all types of paints and primers, including water-based and acrylic. In this case, the device allows you to significantly harden the process of hardening the primer or putty. The material that receives the wave radiation passes from the liquid state to the solid state, which is called hardening, in the language of specialists. And for the whole process takes a maximum of 5 minutes.
Infrared short-wave dryingin the following way. After connecting the device to a power source (this is usually an alternating electric current) in the tool being processed, the top layer of the paint is heated first, which in turn completely prevents the solvent from escaping. This happens when the short-wave dryer is infrared. Long-wavelength devices transmit their power by convection heating. Thus, the source radiating heat to the surface of the paintwork is heated to a temperature of the order of 700-750 degrees Celsius, after which the heating level of the drying object itself increases only to 40 degrees. As a result, the cooling period of the device will be at least 15-20 minutes, while for the hardening of the layers of paint it will be necessary to spend up to 1-2 minutes of time.
By the way, the heating temperature in long-wavedevices are much larger than those of shortwave devices. Such drying infrared can be heated up to 1450 degrees Celsius. Consequently, the heating of the drying object also increases. Due to this, the majority of thermal energy (up to 75 percent) emitted by the device falls not on the upper, but on the lower contour of the paint, after which the hardening occurs with the outer side of the coating.
Modern drying infrared is used inmany branches of economy and industry, as it can quickly bring to the desired condition the surface of almost any material: MDF, decorative glass products, metal car bodies and much more. All this makes it indispensable in the industrial coloring of products and mechanisms.
