<p><P>PROBLEM TO BE SOLVED: To provide a method for improving a crashing property of wooden biomass raw material by specifying the ranges of heating temperature and heating time, and to provide a method for improving the crushing property and the opening property of bamboo. <P>SOLUTION: In the methods for crushing/shredding the wooden biomass, the wooden biomass raw material is thermally degraded at the temperature of≥240°C to≤300°C for the time of≥15 min to≤90 min, thereafter, is crushed and, as a result, the crushing property is improved while suppressing pulverization. Further, in this method, the bamboo is thermally degraded at the temperature of≥170°C to≤220°C for the time of≥15 min to≤120 min, thereafter, is crushed and, as a result, the strength between fibers is weakened while maintaining the strength in a fiber direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
