2. Production of high-density composite materials The chemical composition of bagasse is similar to that of wood, and it is a good raw material for board making. Use bagasse resources to produce high-density composite materials. Due to the small specific gravity of bagasse and good fiber quality, the prepared boards have high strength and light weight, and the boards and profiles produced are not subject to biological damage, low water absorption, and not corroded by seawater; good fire resistance and good resistance Combustion performance, good mechanical processing performance and decorative performance, suitable for furniture, construction, carriages, ships, packaging boxes and other manufacturing industries. The product has strong plasticity. It can directly produce a variety of plates and profiles by replacing different molds or templates, which has great market value. The realization of high-density composite material technology not only solves the pollution discharge problem of agricultural waste and urban waste, but also saves limited forestry resources, which will definitely have a huge impact on my country's environmental protection industry in the 21st century.
