Embodiment 1
[0057] Embodiment 1 compacts the rotten plank separately
[0058] This embodiment provides a kind of dead wood compacted material, the preparation method of this dead wood compacted material comprises the following steps:
[0059] a. High-temperature and high-humidity treatment: place the rotten wood boards in the drying cellar for heating and humidification, adjust the relative humidity in the drying cellar to 50%, the temperature to 50°C, the heating and humidification time to 3 hours, and then adjust the relative humidity in the drying cellar to 80% , the temperature is 44°C, the heating and humidification time is 20 minutes, and the high-temperature and high-humidity treatment rotten wood board is obtained;
[0060] b. Drying treatment: reduce the rotten wood boards treated with high temperature and high humidity to room temperature, equilibrate at room temperature for 12, then place the dried rotten wood boards in a drying cellar, heat up to 120°C, and keep them warm for ...
