Research on new ceramic debinding technology with low energy consumption via dielectric barrier discharge

Abstract

To combat the issue of global warming, we must conserve energy and reduce carbon emissions from energy production and use. Industrial process electrification can greatly save energy and minimize carbon emissions. The energy consumption of debinding and drying in the ceramic industry accounts for about 20%. The conventional thermal debinding method is energy-intensive and time-consuming. It is critical to develop green debinding techniques that are energy-efficient and environmentally friendly. Based on the dielectric barrier discharge measurements, the impacts of various voltages(Upp 16-22kV), frequencies(9-12kHz), air gap widths(0-3mm), and treatment time(0-60min) on the debinding efficiency are investigated in this work for the ZnO ceramic system. Dielectric barrier discharge debinding time and energy consumption per unit volume of sample can be reduced to 5% and 10% of conventional debinding, respectively, which is a potential method to realize electrical energy replacement in the ceramic debinding process.
