The basic UV LED emits energy in these two ranges, but its intense emission at short wavelengths makes it particularly suitable for coatings and thin ink layers. Highly absorbent materials, such as adhesives and screen inks, are better formulated for long-wave curing using long-wave light triggers. The UV curing machine for curing these materials includes LED irradiator and host. This UV curing machine can emit different wavelengths of light according to different LED chips. It can also cope with surface curing while curing UV materials.

 

Many very special applications, such as curing a large number of materials containing titanium oxide as a pigment additive, or curing through plastics or glass, require long-wave curing, because these materials almost completely hinder short-wave curing.

 

Most UV curing involves two ranges of wavelengths working simultaneously. Short wavelength works on the surface and long wavelength works on the deep layer of ink or coating. This theorem is due to the fact that the short wavelength is absorbed in the surface layer and cannot reach the deep layer. Short wave exposure does not lead to surface adhesion, while the lack of long wave energy will lead to poor adhesion. Each formulation and film thickness benefits from an appropriate short and long wavelength energy rate.

 

Characteristics of UV LED Linear Light Source:

 

1: Cold light source, no thermal radiation, especially suitable for liquid crystal edge sealing, film printing requires small heating area.

 

2: Instantly light up, instantly achieve 100% power ultraviolet output, irradiation intensity can reach 6000mW/cm2.

 

3: Small shape - make the equipment easy to integrate into the fully automatic production line and equipment.

 

4: It is a safer and more environmentally friendly choice to replace traditional light sources without using toxic substances and ozone.
