[Low Thermal Effect] the Significant Characteristics of UVLED Cold Light Sources

At present, the use of UVLED light sources is very wide, and one of the most obvious features of UVLED curing light sources is that the thermal effect is low and no radiation. It is precisely because the thermal effect of UVLED facial light source is low. Below I will use a label printing technology to be more sensitive to calories to explain it. The thermal contraction membrane label is a thin film label printed on the plastic film or plastic tube with a dedicated ink. During the label, when heating (about 70 C) Contraction, close to the surface of the container, the thermal contraction membrane label mainly includes a shrinking sleeve label and contraction surround label. The shrinking sleeve tag is based on the heat -shrink film as a substrate. The cylindrical tag made by printing after printing. It has the characteristics of convenient use and is very suitable for alien container. The thermal shrinking film label is part of the label market. It is currently in rapid growth. The market share is expanding. It is expected that the annual growth rate is about 15%, which greatly exceeds the annual growth rate of about 5%of the ordinary label market. Become a highlight of the label printing industry, predicting that the domestic hot film market will grow at a rate of more than 20%within 5 years. The production of thermal contraction label has high technical requirements for technology. For ordinary water -based and solvent -type inks, the drying temperature is too high, then the material occurs in heat contraction; if the temperature is too low, the ink is not completely dry enough. Therefore, The crafts are quite complicated, and the waste rate is high. For UVLED face light sources, in the action of ultraviolet energy, the ink enables polymer substances to form a mesh crosslinker in an instant, the ink is quickly solidified, and the temperature of the printing material has no effect. Therefore, the UV optical curing technology fundamentally solves the problem of the heat shrinking film label fear of heat. UVLED optical curing technology is dry to print ink, and the pure ultraviolet drying rarely generates any heat, and there are many benefits to our environment.
