1.It consists of ultraviolet ray, lamp cover, transform (ballast), capacity (trigger). UV LED irradiation lamp uses UV lamp in high pressure mercury lamp and metal halide lamp market. High pressure mercury lamps are commonly used in domestic equipment, imported equipment, some of which use metal halide lamps. The ultraviolet energy of the lamp is also called osmosis. First, it must meet the spectral wavelength and power density required for UV ink (light) absorption. If the UV lamp power is not enough, even if the light time is longer, beyond the UV curing device,the product cannot be fully solidified. On the contrary, it can make the surface of UV oil (paint) ageing, close, fragile and so on, and ink (paint) bad adhesion can make layer bonding bad. Because low-power UV rays cannot penetrate the bottom of the the ink layer, there is no cure or cure for the bottom.

2.generally, the power of UV LED lamp is 80~120W/cm2. But the higher the power, the hotter it gets. Therefore, we select different power according to curing and curing speed.

3.Cationic photo-curing system UV LED ink curing will not produce unpleasant smell. And once the formation of cationic UV, light curing reaction can continue. This is conductive to deep conservation of thick layer and deep curing ink, which free treatment system is different to achieve.

4.Cationic photo-curing system UV LED ink curing UV LED ink, small volume shrinkage (usually 3% to 5%) improves the adhesion of substrate. After curing 10% of the total shrinkage volume, free radical photo-curing system, matrix adhesion has a greater impact.

5.Cationic photo-curing system UV LED ink or free radical / cationic composite photo-curing system UV ink can improve the speed of light curing, especially color UV ink and ink film thickness UV ink curing, more beneficial.

From cationic curing materials market growth rate higher than that of the UV curing the overall growth rate of the market, we can see that the cationic light curing system or radical/cationic light curing system, UV ink will become UV LED ink is a new development direction.
