Embodiment Construction

[0024] The production method and structure of the densely reinforced laminated veneer lumber provided by the present invention with a wood-patterned surface will be further described below in conjunction with the accompanying drawings.

[0025] The production process steps of compactness reinforced laminated veneer lumber are:

[0026] The first step: processing log wood into veneer sheets;

[0027] Step 2: Remove water from the above-mentioned veneer sheets by cooling or drying and other methods to make them dry;

[0028] Step 3: Put the dried veneer sheet into the container, seal the lid and evacuate to 0.5Mpa, and extract the air in the capillary pores of the veneer sheet to facilitate the soaking of glue (the glue can be used as Adhesives for ordinary laminated veneer lumber, or other curable glues);

[0029] Step 4: Inject the glue solution into the vacuumized container to soak the inside of the veneer sheet;

[0030] Step 5: Take out the soaked veneer sheet, put it in...

Abstract

The invention belongs to laminated veneer lumber technique field, discloses a method which is used to produce compactness intensification laminated veneer lumber. Its main technique features is that including manufacturing the wood to veneer sheet, drying to remove moisture, putting in the container after vacuum pumping, injecting soak, double heating vacuum, pressing overlapped assembly to forming, clipping putting into storage. The laminated veneer lumber prepared by the technique has the features that the thickness can be compressed more than ten percent; the density, hardness, strength can be increased one time; the effects of the water proof, corrosion protection, moth proof are good; and neatness of the surface manufacturing is high. The veneer lumber is manufactured along the certain angle, and can be gained the surface with woodiness figuring shape.

Description

technical field [0001] The invention belongs to the technical field of laminated veneer lumber, and in particular relates to a method for producing densely reinforced laminated veneer lumber. Background technique [0002] At present, the known laminated veneer lumber is formed by processing wood into veneer sheets, applying glue or pouring glue, then stacking layers according to the wood grain direction, and then hot pressing. The laminated veneer lumber produced by this process has limited parameters such as density, hardness, and strength, especially the laminated veneer lumber produced by using soft wood such as poplar, the above parameters are very small, and the application range It is greatly restricted, and the value-added range of processing is also very small. Contents of the invention [0003] The technical problem solved by the present invention, that is, the first purpose is to provide a method for producing densely re...
