[UVLED Light Intensity] UVLED Manufacturer Tells You About These

In the actual use of customers, such problems often occur, that is, I do nt know if the radical intensity of its own UV curing machine is suitable. Today, Tianhui will talk about the main factors that affect the irradiation of UVLED cold light source curing machines. UVLED curing principle I. The characteristics of the characteristics of UVLED cold light source curing machine by UVLED solidification material, decided to enter the cured material emitted by the lamp to cause the light and cause the molecules. UV solidification determines the collision between photons and molecules, which can cause the molecules to spread evenly through materials. In addition to the characteristics of UVLED light sources, the solidified bears also have optical and thermodynamic characteristics. They interact with radiation energy and have a significant impact on the process of solidifying. UVLED's spectral spectral two, spectral absorption, light energy is the amount of ink absorbed into the wavelength within the gradually increasing thickness. The more energy absorbed near the surface, the less energy obtained. However, with the different wavelengths, the longer the wavelength, the more the penetration efficiency, the shorter the wavelength, and the less the penetration part. In terms of the actual production process, the 365nm wavelength UVLED ultraviolet rays It is much better for the watch, and the long wavelength or 405nm penetration is better than 365nm. The overall spectral absorption rate includes all from the influence of light cause, single molecular substances, clustering and additives including pigments. Third, the reflection and scattering are relative and absorbed. The light can be changed by the direction of the ink, which produces reflection and scattering. These factors have reduced the energy reaching the deep UV energy, but improved the solidification efficiency of the reaction. The change curve between UVLED temperature and wavelength 4. The temperature of the cooling system UVLED curing machine has a significant impact on the rate of curing reactions (that is, strong irradiation light). One of the important restrictions that affect the curing process. People who know the temperature characteristics of UVLED lamp beads must know that the higher the temperature, the higher the wavelength of UVLED will drift higher. For example, some domestic lamp beads, when they first use it, the solidification effect is good. Light for a while for a while. After that, as the temperature rises, the wavelength of UVLED lamp beads has changed. 365nm will drift in the direction of 370/380nm. There is no way to absorb the glue or ink of the cause, and naturally cannot complete the cross -linking translation between glue or ink molecules, reflects the macro perspective, that is, the glue and ink are not well -curing or have no solidification.
