摘要

Before coating,more and more plastic parts are being cleaned with CO2 snow jet technology.Besides the significant cost,space and resource savings,as well as the ease with which the cleaning system can be integrated into painting lines,coating properties also benefit from the dry cleaning solution.As with metallic components,plastic components have long been cleaned with powerwash systems prior to painting.The components first pass through a cleaning step with a mostly alkaline medium,followed by several rinsing zones,an adhesive water dryer and a cooling zone.Cleaning not only takes up a lot of production space,but also consumes large quantities of resources.Furthermore,plastic components behave differently from their metal counterparts.The heat introduced during the cleaning step causes the plastic parts to expand,with the result that water is stored.During the drying process,the parts are heated once again.This could be one reason why some of the ingredients used to make the plastic,such as separating agents,additives or fillers,which have migrated upwards from deeper layers,can later be found on the cleaned surface and impair paint adhesion.
