As an outdoor heavy bamboo floor, it is manufactured using international cutting-edge biomimetic technology. Firstly, the bamboo raw materials are processed through 18 thinning processes to produce bamboo filaments with basically uniform morphology. Then, under high temperature conditions, the sugar substances in the cell cavity are pyrolysed, and the bamboo filaments are immersed in a certain concentration of silica sol based formula solution, making the cell cavity filled with silica sol formula liquid. Afterwards, the bamboo fibers are dried, soaked in glue, molded, and finally thermally cured with glue under high temperature and pressure. At the same time, the silica sol also forms crystals under high temperature and pressure, precipitating in the bamboo fibers to form silicified bamboo, thus making the outdoor boards manufactured have strong corrosion resistance, high strength, and non moldy properties.
