[UV Printing] the Difference Between UV Curing and Traditional Curing

The basic principle of UV solidification is to use UV ultraviolet light irradiation to make the molecules of light -sensitive materials decomposed to form a highly active atom or highly active atom group. Finally achieve the purpose of molecular cross -linking polymerization. The dryness of the UV ink is the process of optical chemistry. The speed of light is 3 10km/s, which causes the chemical bonding time for a few seconds, and the printing speed is 5,000 pieces per hour. Different optical reactions and thermal reactions are different. The activation energy of thermal reactions comes from molecular collisions, which is longer, and the activation energy of optical reactions comes from optical energy. Therefore, UV optical curing is much more time -saving than traditional thermal reaction curing, and the finished product can directly accumulate shipments, which is very convenient. In addition, UV optical solidification UV ink and traditional ink dry and more energy saving and environmental protection. UV light curing, especially LED -type UV optical curing, except for producing valid UV ultraviolet rays, infrared and ozone are basically not produced. It is also particularly friendly to the production workshop. It does not produce infrared rays. It means that it will not produce special calories. The latest UV ink curing equipment of Tianhui will become the main force of UV ink curing in the future!
