Embodiment 1
[0033] Embodiment 1: the compression layer thickness control method of wood layered compression, as attached figure 1 As shown, the method specifically includes the following specific steps:
[0034] 1) Moisture content of wood: wood with moisture content from dry to saturated
[0035] Wood with a moisture content of less than 14%, hydrophobic materials such as paraffin, are sealed and then soaked in room temperature water or water heated to below 100°C, or soaked directly without sealing, for 10 minutes to 6 hours, preferably 30 minutes to 3 hours; wood with a moisture content of 14% to 30% can be used directly, or soaked for a short time, sealed or unsealed during soaking, and the time is determined according to the position of the target compression layer; wood with a moisture content greater than 30% is directly preheated ;
[0036] 2) Wood thickness: (determined according to the preset thickness of the compressed layer, the original density of the wood and the final de...
Embodiment 2
[0063] Embodiment 2: the fitting equation of compression layer position and preheating temperature and time is as shown in table 1,
[0064]
[0065] Table 1
[0066] The applicant conducts the test on wood with a thickness of 25mm, and the required compression amount is 5mm. During the preheating treatment, the test is divided into two groups, and the first group sets the preheating temperature as the variable x 1 (or x 2 ), the warm-up time is set to 720 seconds, according to y 1 =a 1 ln(x 1 )-c 1 The logarithmic function relationship of or The quadratic function relationship of the wood is controlled by adjusting the preheating temperature to control the position of the compression layer of the wood to achieve the selective directional densification of the wood; the second group sets the preheating time as the variable x 3 and x 4 , the preheating temperature is 180°C, according to The quadratic function relationship of or The exponential function relationshi...
