Embodiment Construction

[0020] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The embodiment of the present invention provides a wood processing technology, comprising the steps of:

[0022] A. Prepare the first mixed solution: stir malic acid, maleic acid, boric acid, and water according to the mass ratio: 1:4:4:100 to make them completely mixed evenly to obtain the first mixed solution;

[0023] B. Preparation of the second mixed solution: furfural and boric acid are first added to the reactor according to the mass ratio: 15:3, and then the boric acid is added. The boric acid will be added in two times; the temperature of the reactor is controlled. At 120 degrees and a pressure of 1.1 MPa, after 1 to 2 hours, the moisture of the mixed solution in the reactor was volatilized until the remaining solution was 5% of the total weight...

Abstract

The invention provides a wood working process, which comprises the following steps of: the preparation of first mixed solution; the preparation of second mixed solution; square stock impregnation, namely, impregnating a square stock into the first mixed solution to make the square stock absorb the first mixed solution until reaching a completely saturated state, and placing the square stock impregnated in the first mixed solution into the second mixed solution for impregnation to make spaces among wood cells of the square stock absorb the mixed solution until the mass ratio of furfural to the wood is 0.3-0.5:1; hot-pressing, namely, performing hot-pressing on the impregnated square stock; cutting, namely, cutting the square stock into required wood boards; and sanding and notching, namely, sanding and notching the wood boards. The wood boards obtained by the wood working process provided by the invention have the characteristics of high load-bearing properties, high density, high durability, strong bending strength, low water absorption and low expansion ratio.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a wood processing technology. Background technique [0002] When poplar and pine are used as planks, especially for floors, they have defects such as low load-bearing performance, low density, poor durability, low static bending strength, high water absorption and high expansion rate. Contents of the invention [0003] The invention provides a wood processing technology. The processed wood has high bearing performance, high density, strong durability, high static bending strength, low water absorption rate and low expansion rate. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] A kind of wood processing technology, it comprises steps: [0006] Preparation of the first mixed solution: stirring malic acid, maleic acid, boric acid, and water according to the mass ratio: 1:4:4:100 to completely mix t...
