UV light curing

When UV light encounters the polyester, a chemical reaction takes place which makes that the polyester harden. This is extremely effective in comparison with thermally cured liners, as the UV cured liner does not need to be heated to a special temperature to be thoroughly cured. With UV liners, you avoid using energy to heat up water/steam which then has to heat up the entire liner to a certain temperature and time for it to be properly cured.

 

Environmentally friendly

The only energy that is used during UV light curing is the electricity that lights the UV lamps, which is effective in comparison with first heating a large quantity of water.

With UV hardening you avoid dealing with process water that may contain harmful chemicals which must not be released into the environment.

 

Advantages of UV light curing

  • The method is quick. You can cure up to approx. 80 m of liner an hour depending on the dimension and wall thickness.
  • Low energy consumption keeps emissions to a minimal level.
  • No process water which can contain harmful chemicals is created.
  • The equipment requires little space.
