Project TIGI introduction

Tuesday, 14 April 2009 08:40

The project is being executed as part of the KP7 research programme of the European Commission: Research for Associations.
With this programme, SME Associations receive financial support, allowing them to have Research and Development conducted  for which their budget normally would not allow any space.

The project is executed by:
- 3 SME associations
- 5 Research & Development   partners
- 7 galvanization companies.

Participant’s countries of origin are the Netherlands, Spain and Sweden.
The ultimate goal of the project is to implement innovative technologies in Europe’s metal plating industry.

Specifically the project aims on prolonging the lifecycle of the new generation Chrome 6+ free passivation products that are used within the galvanisation industry. The usage of this product was commenced by a directive from the European Commission with regard to the usage of Chrome 6+.

These new passivation fluids are much more expensive than the old fluids containing chrome 6+. By prolonging the lifecycle of the passivation baths, operational costs within the galvanisation industry will be significantly reduced. The environmental burden will also be reduced, since fewer passivation baths are used (less waste, less processing on the ONO installation, etcetera). Prolonging the lifecycle of the passivation bath is accomplished by selectively removing the tramp ions Fe3+ and Zn2+. This is done by applying the hollow fibre membrane technology. The purified passivation fluid is taken back to the bath and the fluid with the tramp ions can be used in a pickling bath. Keeping a constant high level of quality of the passivation bath results in a higher product quality.
