Problems solved by technology

Although the traditional mercury lamp type UV curing equipment and the traditional mercury lamp type UV curing coating ink are cheap in the Chinese market, due to the high maintenance cost and large power consumption of the traditional mercury lamp type UV curing equipment, large carbon emissions and UV The rapid attenuation of the light intensity of the mercury lamp leads to frequent replacement of the ultraviolet mercury lamp, the rise of the surface temperature of the irradiated components leads to the deformation of the heat-sensitive substrate, the large volume leads to a large space occupation, a large amount of ozone is produced, and mercury pollution is large. Committed to improvement, but it has been difficult to break through the limitations of the original hardware, so the UV curing equipment used in the Chinese market for UV curing wood coatings and wood inks is mainly traditional mercury lamp type UV curing equipment
[0005] However, the existing inks are mainly proposed for the traditional mercury lamp type UV ultraviolet curing equipment. There is a lack of UV ultraviolet ink suitable for semiconductor light-emitting diodes to excite ultraviolet light curing equipment, which leads to poor product effects and brings difficulties to industrial production.
