How does the thickness of UV ink affect the curing effect of UVLED? The following is the relationship between the ink thickness and the [UVLED light curing] effect obtained from the experimental analysis of the UVLED curing machine provided by Auvcure: By learning the relationship between the thickness of the UVLED ink and the UV curing effect, we can adjust the appropriate thickness of the UV ink during the UV ink light curing process to achieve the best curing effect.
1, for thicker UVLED ink layer curing law is different from the above, the Beer-Lambert schedule can accurately predict the curing rate at any depth below the surface. The Beer-Lambert equation shows that the light intensity of the surface decreases exponentially with depth. The concentration of absorbent material C is mainly the concentration of resin, the thicker the ink, the harder it is to cure, and the thinner the easier it is to cure. The UVLED light absorption coefficient R of liquid material is mainly the UVLED light absorption of pigment and photoinitiator, and the UVLED light attenuation is strong when the pigment content is high and the pigment particles are large and the UVLED light absorption is strong
2, for thin transparent UVLED coating or extremely thin colored coating exists, UVLED light through the ink layer of large indiscriminate light to reach the substrate, by reflection to the surface, the surface and then reflected to the substrate, this process will occur countless times. The higher the light emission rate of the substrate to UVLED, the greater the effect on curing, the more conducive to curing, especially the aluminized paper effect is excellent, the surface will accept a large number of times from the substrate reflected UVLED light, so that the surface curing rate is greatly improved.
The above is how UV ink thickness on UVLED curing related knowledge, Auvcure is specialized in the development and production of various UVLED point light source, UVLED line light source, [UVLED surface light source] and [UV curing machine] manufacturers, and can provide solutions and customization according to the actual needs of customers.
