Trace contamination on non-conducting surfaces like leather, fabric, paper and plastic are common during manufacturing processes. The origin of such contaminants can be processing aids or lubricants which are transferred from mechanical components. The structures and compositions of these contaminants are very diverse and range from small organic molecules to low melting fats. Heated cleaning treatment is used in manufacturing processes but it may also damage the surface integrity of the material. In a feasibility study, it was shown that a slight increase in temperature of the contaminant can enhance its removal.
The client is seeking a physical or chemical technology / process for localized heating treatment of non-conductive materials. This technology will be used in a cleaning process for the removal of all kinds of contaminants in an aqueous bath. The technology should not be damaging to delicate material surfaces. The requested technology should also be suitable to clean materials of various porosity levels and could be tested in laboratory scale within a couple of weeks.
The most relevant features for the new technology / process include the following:
