UV wavelengths, refers to the light emitted by the UV light source, a definition of light, can be understood as a distance per unit time, , and different wavelengths have different effects on the curing.
Uses of different wavelengths:
In UV curing technology, UV light emission has two wavelengths at the same time for curing work. Because the wavelength is different length, the effect is not the same. The Long wave has strong penetrating power can used for ink or coating, the short wave is used in the surface of ink, which is because the short wave uv led strip has a high energy, but the penetration is not strong for the ink.
Wavelength applications:
The short wave uv led strip will be absorbed in the surface of ink. Because both shortwave and longwave length of each has different effect, but regardless of which a separate application is not able to achieve the desired results, for example,
long-wave’energy is low, it cause poor adhesion, other side because of the short exposure less and make hair stick surface, so it is best The approach is both operation, has reached perfect results, according to different formulations of the film with different energy UV light.
