The feasibility of the effective utilization of combustion ash from a woody biomass power plant as a novel filler added to adhesives used in plywood production is investigated. For this, plywood was prepared with glues containing combustion ashes having different properties, and the adhesion performance of the glues was examined in detail and compared with that of a glue containing calcium carbonate powder as the filler. Through optical microscopy observations and analyses of the adhesive layer in the plywood, the relationship between the properties of the glue, the structure of the adhesive layer, and the adhesion performance was unraveled. Results revealed that the glue containing woody biomass combustion ash without the unburned carbon component shows a better and more homogeneous adhesion performance than that containing calcium carbonate powder. The adhesion performance could be enhanced more uniformly by decreasing the particle size of the filler. The study also indicated that the difference in the adhesion performance according to the kind of filler is not due to the difference in the chemical structure of the adhesive layer, but because of the difference in the denseness of the adhesive layer dominated by the viscosity of the glue. Thus, this study confirms that woody biomass combustion ash could be practically utilized as a filler substitute of calcium carbonate powder in glues for manufacturing plywood.

研究了有效利用木质生物质发电厂燃烧灰作为新型填料添加到胶合板生产中使用的粘合剂的可行性。为此，用含有具有不同性质的燃烧灰的胶制备胶合板，并详细检查该胶的粘合性能，并将其与含有碳酸钙粉末作为填料的胶进行比较。通过光学显微镜观察和胶合板中粘合剂层的分析，揭示了胶水性能，粘合剂层结构和粘合性能之间的关系。结果表明，含有木质生物质燃烧灰而不含有未燃烧碳组分的胶水比含有碳酸钙粉末的胶水具有更好，更均匀的附着性能。通过减小填料的粒径，可以更均匀地提高粘合性能。研究还表明，根据填料种类的不同，粘合性能的差异不是由于粘合剂层的化学结构不同，而是由于粘合剂层的致密性不同，而粘度的高低主要取决于粘合剂的粘度。胶。因此，该研究证实，木质生物质燃烧灰可以实际用作制造胶合板的胶水中碳酸钙粉末的填料替代品。通过减小填料的粒径，可以更均匀地提高粘合性能。研究还表明，根据填料种类的不同，粘合性能的差异不是由于粘合剂层的化学结构不同，而是由于粘合剂层的致密性不同，而粘度的高低主要取决于粘合剂的粘度。胶。因此，该研究证实，木质生物质燃烧灰可以实际用作制造胶合板的胶水中碳酸钙粉末的填料替代品。通过减小填料的粒径，可以更均匀地提高粘合性能。研究还表明，根据填料种类的不同，粘合性能的差异不是由于粘合剂层的化学结构不同，而是由于粘合剂层的致密性不同，而粘度的高低主要取决于粘合剂的粘度。胶。因此，该研究证实，木质生物质燃烧灰可以实际用作制造胶合板的胶水中碳酸钙粉末的填料替代品。但是由于胶粘剂层的密度不同，胶粘剂的粘度决定了胶粘剂层的密度。因此，该研究证实，木质生物质燃烧灰可以实际用作制造胶合板的胶水中碳酸钙粉末的填料替代品。但是由于胶粘剂层的密度不同，胶粘剂的粘度决定了胶粘剂层的密度。因此，该研究证实，木质生物质燃烧灰可以实际用作制造胶合板的胶水中碳酸钙粉末的填料替代品。
