The technology behind polymerisation using pulsed light, updated by EUROFEEDBACK, finally brings an alternative
solution to traditional technology based on mercury lamps.
There are many advantages to pulsed light:
- The low level of infrared light emitted minimises the
heating of the base,
- The instant startup and stop of the lamp removes the need
for the preheating stage,
- Easy electro-control over the flash frequency in line with
the speed at which the target moves,
- Xenon lamps emit very little ozone and, as their energy out
put is better than that of mercury lamps, it is possible
to reduce the number of ventilation units and the electrical
consumption,
- Xenon tubes do not contain mercury, the driers will
therefore comply with future regulations,
- The emission being under very high peak energy and in a
very short space of time, these driers can polymerise
significant thicknesses,
- The spectrum is continually distributed between 200 nm
and 900 nm, there is therefore a good interaction with the
photo-initiator and, consequently, pigment influence
is low. |
