What determines the quality of UVLED curing effect?

Click:[1045] Publish Time:2022-06-02

The following factors affect the UVLED curing effect:


1. Characteristics of the cured material

The curing speed and effect of UVLED curing machine mainly depends on how easy it is for UV light to enter the curing material to trigger photoinitiated molecules. UV curing depends on collisions between photons and molecules. Light can induce uniform diffusion of molecules through the material. In addition to the characteristics of UVLED curing machines, the interaction of the optical and thermodynamic properties of the cured material with the radiant energy has a significant impact on the curing process.


2. Spectral absorbance

Light energy is the wavelength that the UV coating absorbs in increasing thickness. The more energy absorbed near the surface, the less energy deep layers get. But this varies by wavelength. The total spectral absorbance includes the effects of photoinitiators, unimolecular species, polymers and additives, including pigments.


3. Reflection and Scattering

In contrast to absorption, light energy is usually due to matrix materials or pigments in the curable material, and is usually redirected by the ink, causing reflection and scattering. These factors reduce the deep UV energy, but increase the curing efficiency at the reaction site.

4. Infrared absorption rate

Temperature has a significant effect on the rate of the curing reaction; although the temperature rise during the reaction is also relatively influential.


5. Significance of Spectral Absorption

Substances absorb light differently depending on the wavelength. Obviously, short UV wavelengths (200~300nm) will be absorbed by the surface and will not reach the bottom layer at all. Even a photoinitiator absorbs the wavelength range it is sensitive to, preventing wavelengths from reaching the deep photoinitiated molecules.


6. Suitable wavelength of UVLED curing machine

The UVLED wavelength required for curing varies by UV coating. When choosing a UVLED curing machine, you need to choose according to the wavelength required for the UV coating. Use UVLED curing machine with appropriate wavelength to achieve better curing effect.
