Example Embodiment
[0018] Example l
[0019] Wood section peeling, veneer drying, veneer cutting to obtain the veneer of the prepared plywood, and then the veneer is treated as follows:
[0020] (1) Prepare antiseptic solution: prepare antiseptic solution at a molar ratio of furfuryl alcohol and ammonium borate of 1:2;
[0021] (2) Anticorrosive solution treatment veneer: Put the veneer into a vacuum pressurizing tank, connect the vacuum equipment and pressurizing equipment (that is, turn off the pressure pump when starting the vacuum pump to vacuum; turn off the vacuum pump when turning on the pressure pump), and turn it on The vacuum pump performs vacuum processing to make the relative vacuum in the vacuum pressurized tank reach -0.08 MPa. After holding for 50 minutes, turn off the vacuum pump and introduce the configured anticorrosive solution until the relative vacuum in the vacuum pressurized tank is 1Mpa, open The pressure pump continues to feed the anticorrosive solution into the vacuum pressur...

[0025] Example 2
[0026] Wood section peeling, veneer drying, veneer cutting to obtain the veneer of the prepared plywood, and then the veneer is treated as follows:
[0027] (1) Configure antiseptic solution: mix furfuryl alcohol and ammonium borate at a molar ratio of 1:2.3 to configure antiseptic solution;
[0028] (2) Anticorrosive solution treatment veneer: Put the veneer into a vacuum pressurizing tank, connect the vacuum equipment and pressurizing equipment (that is, turn off the pressure pump when starting the vacuum pump to vacuum; turn off the vacuum pump when turning on the pressure pump), and turn it on The vacuum pump performs vacuum processing to make the relative vacuum in the vacuum pressurized tank reach -0.085MPa. After holding for 55 minutes, close the vacuum pump and introduce the configured anticorrosive solution until the relative vacuum in the vacuum pressurized tank is 1.5Mpa. Turn on the pressure pump, continue to pass the anticorrosive solution into the va...

[0032] Example 3
[0033] Wood section peeling, veneer drying, veneer cutting to obtain the veneer of the prepared plywood, and then the veneer is treated as follows:
[0034] (1) Configure antiseptic solution: mix furfuryl alcohol and ammonium borate at a molar ratio of 1:2.8 to configure antiseptic solution;
[0035] (2) Anticorrosive solution treatment veneer: Put the veneer into a vacuum pressurizing tank, connect the vacuum equipment and pressurizing equipment (that is, turn off the pressure pump when starting the vacuum pump to vacuum; turn off the vacuum pump when turning on the pressure pump), and turn it on The vacuum pump performs vacuum processing to make the relative vacuum in the vacuum pressurized tank reach -0.09MPa. After holding for 60 minutes, the vacuum pump is turned off, and the configured anticorrosive solution is introduced at the same time until the relative vacuum in the vacuum pressurized tank is 2.0Mpa. Turn on the pressure pump, continue to pass the antic...
