Embodiment 1
[0024] Present embodiment is an example of the method for fast-growing Chinese fir compression compaction of the present invention, comprises the following steps:
[0025] (1) processing of Chinese fir wood, processing the sapwood of Chinese fir wood into a wood block sample with a size of 20*20*20mm;
[0026] (2) Preparation of fir compression and densification pretreatment solution, configure a pretreatment solution of 2.5mol / L sodium hydroxide and 0.4mol / L sodium sulfite, stir evenly, and boil;
[0027] (3) Pretreatment of fir compression and densification, placing the fir block sample in a boiling pretreatment solution at 100°C for 4 hours, and then in boiling deionized water several times to remove chemical substances;
[0028] (4) balance the moisture content of the wood before pressing, and control the moisture content of 60% of the fir block sample after the pretreatment;
[0029] (5) Compression and densification of Chinese fir wood, place the wood block sample with ...
