Depending on the lengthwave, the spectrum of solar radiation can be divided into seven segments of radiation - X-rays, gamma rays, visible light, radio waves, microwaves, infrared radiation and visible light. The human eye is able to perceive only "visible radiation." We call it light. Its unusually vivid example can serve as a rainbow, where a very ordinary white color is decomposed into certain segments. Whether it's an infrared camera.
Infrared radiation was discovered at the very beginning of the 19th century. It represents
- Longwave.
- Medium wave.
- Shortwave.
Artificial sources of such waves canserve as incandescent lamps, ceramic or metal plates, gas burners, spirals, etc. Currently, an infrared camera is widely used in various areas of our
Perspective and current applicationthermal energy of these waves - drying and sterilization of various products and materials. The infrared drying chamber helps to dry and disinfect paintwork materials and food products. Three methods of drying are mainly used in industry:
- Thermoradiation method (using infrared radiation).
- Convective method (using hot air).
- Combined.
The infrared camera helps in working with anytype of enamels and paints, including water-soluble and acrylic. In the process of such drying, paints and varnishes are transferred from a liquid to a solid state; chemists call this curing. During drying in the convection chamber, the top layer of the coating first dries and heats up, subsequently preventing the exit of the solvent.
Among other things, do not forget thatdrying time depends on the color, which has the paint and its composition. This is due to the fact that different materials may have different reflectivity. Light colors of the rays of the rays do not absorb and reflect only a part of them, which is why their drying will take a little longer. At the same time, metallic paint can enhance this effect. They contain aluminum particles, reflecting the rays like a mirror. Dark paint dries much faster.
