Problems solved by technology

[0005] The traditional anti-corrosion treatment is outsourcing methods such as painting the surface of the wood or pasting veneer materials. These methods can guarantee the service life of the wood in a short time, but they cannot prolong its service life for a long time.
When the existing pressure method treats wood, the preservative is directly pressed into the cells of the wood, which destroys the internal structure of the tree

Embodiment 1

[0018] A wood preservative treatment method, comprising the following steps:

[0019] (1) Put the wood in a closed pressure treatment tank, compress the air, keep the pressure at 0.2MPa, the temperature in the tank is 70°C, and the pressurization time is 10min;

[0020] (2) Maintain the pressure in step (1), fill the pressure treatment tank with pure water, and keep the pressure at 0.2MPa during the water addition process;

[0021] (3) When the pure water fills the pressure treatment tank and the temperature reaches the temperature required in step (1), slowly increase the pressure in the tank, keep the pressure at 0.3MPa, and keep the time for 40 minutes;

[0022] (4) Inject preservative into the tank and maintain the pressure in step (3). When the tank is filled with preservative and the temperature reaches the temperature required in step (1), start to slowly reduce the pressure in the tank to a standard atmospheric pressure , the holding time is 60min;

[0023] (5) Reduc...

Abstract

The invention belongs to the field of wood preservative treatment, and particularly relates to a wood preservative treatment method. The wood preservative treatment method comprises the following steps of injecting purified water into wood cells by utilizing a pressure treatment tank, then permeating a preservative into the wood cells via the permeation effect of cell membranes, so that the wood has a long-time preservative effect. According to the invention, the wood cells are subjected to pressurization and water injection, and the preservative is injected via the permeation effect of the cell membranes, so that on one hand, the problem that the internal structure of the wood is damaged due to direct pressurization and injection of the preservative to the wood cells is solved, and on the other hand, the preservative is injected into the cells, so that the preservative time is prolonged, and good permeation property and high loss resistance are achieved. By adopting the method, even if the chemical preservative is used, the pollution to the environment by the preservative is greatly reduced.

Description

technical field [0001] The invention belongs to the field of wood preservatives, and in particular relates to a wood preservative treatment method. Background technique [0002] Wood preservative treatment method is a class of chemical agents applied to wood and wood products to inhibit or prevent fungi, insects and marine borers and other organisms from growing and multiplying in wood. Antiseptic treatment of wood can prolong the service life of wood products and reduce the demand for wood, which is an important way to protect forest resources. [0003] Wood is one of the important raw materials for national construction and people's daily necessities, such as building materials and industrial materials. With the improvement of people's living standards, the demand for wood is also increasing. Wood is a natural organic material with obvious biological characteristics, and is easily attacked by bacteria, insects, marine borers and other organisms. Therefore, the long-term...
