Embodiment 1

[0024] 1) Standing tree selection. The tree species of producing anticorrosive wood must select the kind that grows rapidly, and material is better, and present embodiment selects poplar for use, chooses the live poplar tree that branch is less in the above-mentioned tree species, and stem is straight and perfect, without disease and insect damage.

[0025] 2) Sapwood moisture cutting and sealing: The sapwood is sawed at a distance of 20cm from the standing tree to the ground, and the sawing depth is required to be the thickness of the sapwood.

[0026] 3) Heartwood moisture sealing: After the sapwood sawing is completed, the heartwood moisture sealing is carried out, and the new type of liquid paraffin is used to seal the heartwood moisture, and neoprene is injected into the circular area of ​​the sawn sapwood section, and the periphery of the sapwood sawing is made of metal. The rings are reinforced to prevent the trees from being blown down by the wind.

Abstract

The invention provides a wood preservative treatment method. The method comprises the following steps: (1) sawing the sapwood of a standing tree until heartwood is exposed so that the sapwood of the standing tree is vertically disconnected; (2) after sawing the sapwood, carrying out water sealing on the heartwood; infusing a chloroprene rubber adhesive to the sections of the sapwood, and at the same time sealing the exposed heartwood after sawing the sapwood by using liquid paraffin; (3) drilling an infusion hole used for infusing a preservative in the standing tree; (4) putting the prepared preservative into a container, hanging the container on a trunk above the infusion hole of the standing tree, infusing the preservative in the container into the infusion hole of the standing tree by using an infusion tube. Compared with a traditional preservative treatment method, the treatment method is good in preservative treatment effect, does not have treatment for preservative waste liquid, and is higher in environmental safety.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a wood antiseptic treatment method. Background technique [0002] So far, the most commonly used method to prevent wood decay is to use chemical agents to preservative, and the selected anti-corrosion treatment method is the vacuum pressure impregnation method. This method can make the preservative penetrate into the interior of the wood to meet the anti-corrosion requirements, but the main problems are the investment in equipment, low treatment efficiency, uniformity of treatment, recovery of chemicals after anti-corrosion treatment and treatment of waste liquid. [0003] With the further development of the internationalization process, my country's requirements for the use of anti-corrosion wood are becoming more and more standardized. The requirements for the use of preservative wood mainly limit the drug loading and penetration of preservatives in wood according to the...
