The principle and application of uvled surface light source curing
Nowadays, the UV LED surface light source curing technology continues to develop and mature. The following introduces its curing principle and application. If you want to know more case information or have related needs, please contact Height-LED.
1. UV LED surface light source curing principle
UV LED light source curing technology is a curing technology based on ultraviolet light emitting diodes (UV LED). The principle of this technology is to use the ultraviolet radiation generated by UV LED to excite the photoinitiator in the liquid UV material to generate free radicals or cations. Thus triggering the polymer material (resin) containing active functional groups to polymerize into an insoluble and infusible solid coating film.
Specifically, UV LED light source curing is firstly that the ultraviolet radiation emitted by the UV LED is focused by the condenser lens to form a high-intensity ultraviolet beam; secondly, the ultraviolet radiation emitted by the UV LED is focused by the condenser lens to form a high-intensity ultraviolet beam. The ultraviolet beam; again, excited state free radicals or cations trigger the polymer material (resin) containing active functional groups to polymerize into an insoluble and infusible solid coating film; finally, under the continuous action of ultraviolet radiation, the polymer material is continuously cross-linked and polymerized , to form a three-dimensional network structure of high molecular polymer, to complete the curing process.
