Research Abstract

A new construction board was produced in this study. The bamboo, and bamboo charcoal an unused biomass used as the material.The 4M-NaOH soln. and sodium silicate powder were used as the inorganic adhesives in place of organic one.The measurements of apparent density, water absorption thickness expansion rate, bending strength, surface hardness, and microscopy observation were performed to check mechanical properties of the boards. The following comprehensive result was provided by the experiments. When the board was produced at 220degree C and 20MPa with 50% bamboo charcoal, the maximum value of apparent density (0.6), the bending strength (30kg/cm2), the water absorption thickness expansion rate(5.2), and surface hardness (1000N) were obtained.Because these values were passed JIS for MDF board, it concluded that the board obtained in this study is available the commercial boards in the near future.
