Problems solved by technology

Existing wood modification method generally has: 1, impregnating treatment method, just carry out vacuumizing treatment to wood earlier, add modifier in wood then, inject medicine in wood by pressure treatment afterwards, although this kind method improves However, in this method, the trees are generally treated after they are felled, and the chemicals cannot penetrate into the wood texture well, which affects the mechanical properties of the modified wood. It is more troublesome, and the modifier after soaking will pollute the environment if it is not properly handled; Although the method can change the mechanical properties of wood without the use of modifiers, this method also requires the use of a variety of equipment, and the operation is cumbersome. reduce the mechanical properties of wood

preparation example Construction

[0025] The invention provides a kind of preparation method of standing modified wood, comprising the following steps:

[0026] 1) Select live standing trees with a tree age of more than 6 years and a trunk diameter of 16 to 20 cm;

[0027] 2) At the place where the trunk of the living tree is 20-50cm above the ground, drill holes vertically to the trunk, straight to the pith center of the trunk, the diameter of the holes is 10-30mm, and the number is 6-12, and the holes are evenly distributed along the circumference of the trunk ;

[0028] 3) insert the pipeline into the hole drilled in step 2), inject modifier through the pipeline, and the other end of the pipeline is connected with the container containing the modifier, wherein the container of the modifier is 30cm higher than the hole, and is higher than the crown of the tree. Low; with this injection method, the injection of the agent can be completed without large-scale equipment, and it has the advantages of simple oper...

Embodiment 1

[0037] Choose the fast-growing poplar whose tree age is 6 years and whose trunk diameter is 16cm. At its growth height of 20cm and 40cm from the ground, respectively drill 12 holes with a diameter of 10mm vertically to the trunk. distribution; then insert the pipeline used to inject the nano-phenolic resin composite material, that is, the modifier, and the other end of the pipeline is connected with the container filled with the nano-phenolic resin composite material. Flow, permeate and diffuse to the whole standing tree, and after 2 days, the modification of the standing tree is completed by cutting down. Wherein the nano-phenolic resin composite material container should be close to the standing tree, and should be 30cm higher than the hole and lower than the tree crown, and a shelf should be used to carry the container.

Embodiment 2

[0039] Choose the fast-growing poplar whose tree age is 10 years and whose trunk diameter is 20cm. At its growth height of 30cm and 50cm from the ground, respectively drill 6 holes with a diameter of 30mm vertically to the trunk, straight to the trunk pith center, and the holes are uniform along the trunk circumference. distribution; then insert the pipeline used to inject the nano-phenolic resin composite material, that is, the modifier, and the other end of the pipeline is connected with the container filled with the nano-phenolic resin composite material. Flow, permeate and diffuse to the whole standing tree, and after 4 days, the modification of the standing tree is completed by cutting down. Wherein the nano-phenolic resin composite material container should be close to the standing tree, and should be 30cm higher than the hole and lower than the tree crown, and a shelf should be used to carry the container.

Abstract

The invention provides a standing modified timber, a preparation method of the standing modified timber, a standing timber modifier, and a preparation method of the standing timber modifier. The preparation method of the standing modified timber includes steps: the growing standing timber is drilled, the standing timber modifiers are injected to holes via the holes, and the modifiers are infiltrated and diffused into the whole standing timber by employing the transpiration effect of trees. The standing modified timber prepared by employing the process is the standing modified timber with high density, small shrinkage coefficient, and high anti-bending strength, and the modification method is advantaged by no environmental pollution, low energy consumption, short processing cycle, and simple and easy operation.

Description

【Technical field】 [0001] The invention belongs to the technical field of forestry planting, and relates to a standing modified wood, a preparation method of a standing modified wood, a standing modifier, and a standing tree modifier. Preparation. 【Background technique】 [0002] The history of human beings using wood has been very long, and it will last for a long time, but wood resources are increasingly scarce today. Therefore, whether it is from the perspective of protecting forest resources or meeting the growing demand for wood From a perspective, we believe that the properties of the currently planted fast-growing forest wood and the wood with poor performance in natural forests should be changed, giving them better performance, and even adding some properties that natural wood does not have, so that they can meet People use it and it will be a good deed that benefits society and benefits the planet. [0003] Since the founding of the People's Republic of my country, ...
