Abstract

The invention belongs to the technical field of wood machining, and particularly relates to a machining method capable of improving corrosion resistance of carbonized wood. The method comprises board pretreatment, oxidation treatment, carbonization, mixed powder treatment and hot pressure machine treatment. Compared with the prior art, the method has the beneficial effects that a pretreated board is subject to oxidation treatment through a hydrogen peroxide mixture, a lignin structure on the surface of the board is more compact, water absorption functional group hemicellulose is regrouped, carbonization is carried out, nutrition components are destroyed, the higher anti-corrosion insect prevention function is achieved, and the surface of the wood has the good physical property; the mixture powder is put on the board carbonization layer surface through high pressure, in cooperation with polishing hot pressing, a compact hydrophobicity thin film is formed on the surface of the board, the board surface is smooth, wear-resisting, high in stability and high in corrosion resistance, the board is placed for one month in the environment with the temperature of 30 DEG C to 40 DEG C, and the relative humidity of 75 DEG C to 80 DEG C, and the smoothness and water resistance of the board surface are not changed.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a processing method for improving the corrosion resistance of carbonized wood. Background technique [0002] Carbonized wood is the most effective way to solve the use of wood. It can avoid rot, distortion and cracking caused by changes in moisture content or stress, etc. It is green and environmentally friendly. Some carbonized wood has no surface treatment, and adding treatment later will greatly increase the use cost of carbonized wood. Due to the rough surface, its wear resistance and stain resistance are relatively poor, which limits the use of carbonized wood. At the same time Carbonized wood also has disadvantages such as low stability, insufficient strength, and poor durability. Therefore, further improvements in the processing method of carbonized wood are needed. Contents of the invention [0003] The object of the present invention is to provide ...
