Polymerization with Pulsed Light
The pulsed light systems have also been designed for polymerizing inks (offset, screen), UV glues and UV varnish.
The polymerization is a chemical process which drives the matrix or the resin to irreversible solidification. That pulsed light technology brings an alternative to traditional technology based on mercury lamps.
The advantages of pulsed light are:
- The low radiation in the infrared spectrum to minimize the heating of the support,
- The lamp does not need a preheating to produce UV light,
- The speed of the flash frequency is tied to the target speed of movement.
- Xenon lamps emit very little ozone, and as their efficiency is better than the mercury lamp, it is possible to reduce the fan units
- Xenon tubes contain no mercury, these dryers will therefore comply with future regulations.
- The transmission is realized with very high peak power in a very short time, so these dryers can polymerize very thick.
The spectrum is allocated continuously from 200 nm to 900 nm, so there is a good interaction with the photoinitiators and therefore the influence of the pigments is low.
Depending on customer needs, we can provide electrical cabinets with one or more lamp units. The pulsed light system incorporates a water cooling system in order to control the temperature of lamp units.
For example, the PLY.40.10.R-02W reference is able to polymerize ink on a 800 mm of width paper, running at 2 meters per second.
Each application needs specific requirements. So do not hesitate to contact us for more details.
