  • The bamboo residues were used as raw materials for hydrothermal treatment,high temperature carbonization,and hydrothermal carbonization pretreatments,and to prepare non-adhesive molded compact materials. The material color,profile density,XRD and infrared spectrum properties were analyzed. The results showed that the total color difference between high temperature carbonization and high temperature hydrothermal was greater than that of hydrothermal treatment,high temperature carbonization had a greater impact on material color than hydrothermal treatment. The density of the pretreated non-adhesive molded material increased rapidly within the range of 0~2mm,and the core layer distribution was relatively uniform. The total average density of the hydrothermal carbonized non-adhesive molded material was greater than that of hydrothermal treatment,high temperature carbonization and untreated distribution was uniform. Hydrothermal treatment increased the crystallinity of cellulose,while high temperature treatment reduced 5% and hydrothermal carbonization reduced 3.4% the crystallinity. High temperature carbonization and hydrothermal treatment had no effect on the characteristic peaks of cellulose,but changed the characteristic peaks of semi-fiber and lignin. High-temperature carbonization had a greater effect on the carbonyl group of the processing residue than hydrothermal treatment.
