Embodiment 1

[0072] A device for strengthening wood such as figure 1 As shown, it includes an anode water tank 1 , a soaking water tank 2 and a cathode water tank 3 , and power supply components. A hole 5 is provided on the side walls of the anode water tank 1 , soaking water tank 2 and cathode water tank 3 . The holes 5 are used to support the wood 11 to be treated, and one end of the wood is positioned in the anode water tank 1, the middle section is positioned in the soaking water tank 2, and the other end is positioned in the cathode water tank 3, and the holes 5 are all provided with leak-proof rubber gaskets (liquid-proof pads 10). The bottom of the side walls of the anode water tank 1 , the immersion water tank 2 and the cathode water tank 3 are provided with a drain valve 8 for discharging the liquid in the water tanks, and a pulley 9 is provided at the bottom. The power supply component includes a set of electrodes connected to the DC stabilized output power supply 6 and the wire...

Embodiment 2

[0074] A device for wood strengthening treatment, comprising an anode water tank, a soaking water tank and a cathode water tank, and a power supply component. Three holes are arranged on the side walls of the anode water tank, the soaking water tank and the cathode water tank. One hole in each tank is used to support one piece of wood to be treated (a total of 3 pieces of wood to be treated), and one end of the wood is located in the anode tank, the middle is located in the soaking tank, and the other end is located in the cathode tank. The holes are all set Leak-proof rubber gasket (fluid-proof gasket). The bottoms of the side walls of the anode water tank, the immersion water tank and the cathode water tank are provided with drain valves for discharging the liquid in the water tanks. The power supply part includes 3 sets of electrodes connected to the DC regulated output power supply (power supply) and wires, each set of electrodes includes a positive electrode and a negativ...

Embodiment 3

[0076] A kind of method that adopts the equipment of wood strengthening treatment of embodiment 1 to carry out wood strengthening treatment, its specific steps are as follows:

[0077] ①Wood pretreatment: select a piece of poplar wood with a diameter D of 13cm and a length of 5m, soak it in a saturated sodium chloride solution for 24 hours, and then take it out to obtain the wood 11 to be treated after soaking in the conductive solution;

[0078] ②Put the wood 11 obtained in step ① through the figure 1 The holes 5 of the anode water tank 1, the soaking water tank 2 and the cathode water tank 3 shown in , and use the leak-proof rubber gasket (leakage-proof gasket 10) to block the gap between the wood and the hole, and fix the wood;

[0079] ③ if figure 1 As shown, the electrodes are fastened to the wood, one end of the wood is fastened to the positive electrode 4-1, and the other end is fastened to the negative electrode 4-2, and the positive electrode 4-1 and the negative ele...

Abstract

The invention discloses a device and method for wood strengthening treatment. The equipment includes an anode water tank, a soaking water tank and a cathode water tank, and a power supply part, and at least one hole is arranged on the side wall of the anode water tank, the soaking water tank and the cathode water tank; the hole is used to support the wood to be treated, and one end of the wood is positioned In the anode water tank, the middle section is located in the immersion water tank, and the other end is located in the cathode water tank; the power supply part is used to provide an electric field force, so that the mineral particles with different electronegativity contained in the anode water tank, soaking water tank and cathode water tank enter Treat the inside of the board. Using the device and method of the invention to strengthen the wood can improve the density, strength and dimensional stability of the wood.

Description

technical field [0001] The invention relates to a device and method for wood strengthening treatment. Background technique [0002] With the continuous strengthening of natural forest protection, forest harvesting has rapidly changed from natural forests to artificial forests. However, some poor-quality tree species in plantations, such as larch, camphor tree, birch, masson pine, etc., have not been efficiently utilized. In order to realize the effective allocation of plantation wood resources, the modification of plantation wood is more and more important. Therefore, the focus of wood modification in the future is still to resist the high-grade of wood, improve the utilization rate of wood from the aspects of increasing the density and strength of wood, improving the dimensional stability of wood, and prolonging the service life of wood. [0003] At present, the traditional wood modification technology mainly includes wood plastification, wood impregnation, wood heat trea...
