1. How is the ink glue cured by UV light?
This ultraviolet light is the same as the ultraviolet light contained in sunlight. The difference is that the ultraviolet light contained in the natural light that the sun shines on the earth contains different wavelengths and less content. The UVLED UV curing machine used in industrial production is a pure wave UV device, which converts most of the electrical energy into UV waves and releases them. Use such ultraviolet equipment to irradiate the curing ink and glue, and the UV ink and UV glue with an appropriate amount of photoinitiator can be cured in 1 second when they are cured by ultraviolet radiation. When UV ink and UV varnish are irradiated by ultraviolet rays, they are mediated by photoinitiators to promote UV coating materials to be quickly light-cured, which meets the requirements of industrial production.

2. Principle and precautions of UV curing glue
The principle of UV curing glue is the same as that of UV ink curing, and it is also light-induced curing. Glue is easier to cure than UV ink, and this conclusion is also the role of light guide. It also depends on the light transmittance of the UV coating material. The UV glue here is mostly transparent or translucent material. The ultraviolet light can be directly illuminated on the glue with good light transmittance. However, it can reach the bottom of the glue coating through the surface and middle layers of the glue. The UV light energy is almost the same as the UV light energy irradiated to the surface of the UV glue. Such UV coatings are instantly cured when combined with LED UV pure-wave ultraviolet rays.

Since glue is a UV coating material that is easily cured by light, attention should be paid to the intermediate environment after dispensing to the UV irradiation area when applying or dispensing glue. The thin glue layer is easy to cure in advance in the natural light of the intermediate environment or Semi-cured. For example, in the production of a product, two accessories need to be glued together. If an intermediate environment pre-curing occurs, the other fitting cannot be in place. If semi-curing occurs, subsequent accessories may not be installed or displaced.
