Abstract
This paper presents the results of a design management study aimed at replacing polyurethane (PU) coatings with titanium dioxide (TiO2) coatings activated through plasma ionization. PU coatings are commonly used in the bamboo furniture industry for surface protection and as part of the luxurizing process. However, their application demands repeated use and large quantities of PU material to achieve the desired surface strength and durability. Furthermore, the aromatic compounds present in most PU sealants pose health risks and create environmental hazards at the end of the furniture’s life cycle. Transitioning to eco-friendly materials or reducing harmful compounds is a critical step toward sustainable practices in the industry. In our study, a plasma ionization device and process were developed. The dielectric barrier discharge (DBD) plasma actuator was designed based on specific parameters, including the lengths of exposed and insulated electrodes, dielectric thickness, gaps between dielectric and electrode tips, and applied voltage and power. Plasma ionization, generated by high-voltage electrodes, was used to treat bamboo surfaces, producing positive and negative ions to facilitate TiO2 adhesion during the coating process. This process was conducted under atmospheric pressure and room temperature within a closed system. The findings demonstrate that TiO2 coatings activated by plasma ionization emit lower carbon dioxide and exhibit better eco-efficiency compared to PU coatings. This paper proposes the detailed designs of the plasma ionization device and process tailored for TiO2 application, highlighting their potential for reducing environmental impact while maintaining performance standards.
