Alternatieven voor het thermisch verzinken van atmosferisch blootgestelde metaaloppervlakken
report
Metal surfaces that are exposed to the atmosphere are sources ofsignificant
diffuse emission; this emission of heavy metals to the soil and the surface water is
mainly a result of corrosion of the surface layer. An inventory of atmospherically
exposed metal surfaces has shown that the emission of zinc, originating from hot-dip
metal surfaces, is the largest source. With a view to reducing diffuse zinc emissions, a
study has been conducted into alternatives for hot-dip zinc coatings of
atmospherically exposed metal surfaces.
The project can be divided into two phases.
The most important parts of the first phase are the inventory and the
assessment/selection of'clean' alternatives for hot-dip zinc coatings ofmetal surfaces.
A report has been written, that states the results of this research phase. It describes
and discusses the results that concern surface technology, and goes deeply into the
methods applied in the assessment and selection [3].
In the second phase ofthe research, the results ofthe first phase have been submitted
to a group of persons who are practically involved in this subject, the 'field workers',
such as suppliers, commissioning parties, and environmental experts. The aim ofthis
was to determine the problems that could occur on implementation of the selected
alternatives.
