Hello, everyone, I all know that [UVLED light source] has a variety of bands, so the role of a variety of bands is different, today we will follow the small edition of Koinu precision optoelectronics to learn this knowledge together.
The most basic UVLED emits energy in both ranges, but its strong emission at short wavelengths makes it particularly suitable for coatings and thin ink layers. Highly absorbent materials, such as adhesives and screen inks, are formulated to be more suitable for long-wave curing using long-wave light triggers. The UV curing machine used to cure these materials includes the LED irradiation head and the host, the UV curing machine can emit different wavelengths of light according to the different LED chips, and can cope with the curing of the surface layer while curing the UV material.
Many very specific applications, such as curing materials that contain large amounts of the pigment additive titanium oxide, or require curing through plastic or glass, require long-wave curing because these materials almost completely block short-wave curing.
Most [UV curing] contains two ranges of wavelengths that work simultaneously. Short wavelengths work on the surface, and long wavelengths work on the deep layers of the ink or coating. This theorem is a consequence of the fact that short wavelengths are absorbed at the surface and cannot reach the deeper layers. Short-wave exposure will not lead to sticky surfaces; The lack of long wave energy will lead to poor adhesion. Each formulation and film thickness will benefit from an appropriate short – and long-wavelength energy rate.
What is explained above is the relevant knowledge of the role of UVLED wavelength.
