LED UV curing system application in wood industry

Click:[1580] Publish Time:2018-06-14

LED-UV curing technology has a constant light intensity, excellent temperature control, portable environmental protection features and other advantages, more with a relatively low procurement costs and almost zero maintenance costs, UV curing process to enhance the quality and energy saving Played a catalytic role.From furniture to cabinet doors to parquet flooring, wood processing industry leading enterprises are keen to use UV LED curing for wood coating for many reasons, but the most important because of the low temperature characteristics of LED light source.The current UV LED curing lamps can be used in a variety of areas, such as optics, electronics, precision parts, medical equipment, printing, head and handicrafts, etc., in the wood industry can also play a great role.The traditional curing method uses a conventional UV lamp or an arc lamp, which will heat the wood surface to raise the temperature by 60 degrees Celsius, while the use of Height-LED revolutionary UV LED curing, the workpiece surface to enhance the temperature is less than half of the traditional curing method. In addition to being used for wood curing, it can be used in a wide variety of applications, such as printing on paper, film, plastic or glass products, and is a safer and more environmentally friendly solution to replace mercury lamp curing.Whether it is a b-stage filler or a gel filler, or a hardened surface coating, the wood product typically passes through up to 10 UV curing stations in the surface processing flow. The use of multiple traditional arc lamps or microwave light sources produces high temperatures that tend to damage wood.It is understood that high temperature will cause great trouble on the wood coating, especially for resin or high oil content such as pine wood, fir wood, spruce and mahogany. At the same time, the high temperature causes the resin and oil to float on the surface of the wood, which can cause discoloration and coating adhesion problems. While UV LEDs deliver less heat to the work surface, eliminating these problems and reducing product waste.
