UV light curing machine is the use of ultraviolet (UV) irradiation of special glues and coatings ﹑ triggered by the photoinitiator (photosensitive agent) to produce free radicals or attached ions, which in turn cause polymerisation and crosslinking reaction, this reaction in a very short period of time to form a network structure of polymers so as to achieve the material's curing, the wavelength of the UV light is usually in the 200 nm to 450 nm between the wavelengths and different wavelengths and different wavelengths of UV light can be selected. Different wavelengths and different bands of UV light, when these wavelengths of UV light waves coated or printed materials after the absorption of triggering the reaction of the photoinitiator, so that the material from the liquid or viscous state into a solid solid, to achieve rapid drying and curing process.
