Problems solved by technology

[0003] At present, the wood grain of the modified wood is not clear, the surface wood color is uneven, and there are still defects such as heartwood, sapwood, early wood and late wood color difference, especially if the log is not treated in time, it will cause color change, so in Direct use often cannot meet the requirements of furniture production

Abstract

The invention relates to the field of furniture materials, and discloses a wood treatment process, which comprises: a, soaking wood for 1-2 h with a dilute sulfuric acid solution; b, washing the woodwith clear water; c, soaking the wood for 30-100 min with a sodium hydroxide solution; d, washing the wood with clear water; e, coating the wood with a bleaching agent; and f, washing the wood with clear water, and drying. According to the present invention, the method has advantages of low cost and high efficiency, and the treated wood has good quality and excellent appearance.

Description

technical field [0001] The invention relates to the field of furniture materials, in particular to a wood treatment process. Background technique [0002] Wood is a renewable natural material, which is widely used in furniture production due to its high strength-to-weight ratio, easy processing, and good insulation properties. However, most of the existing wood used in furniture production has disadvantages such as low density, low mechanical strength, poor dimensional stability and water absorption resistance, and the range of use is greatly limited. Moreover, with the reduction of timber resources and the improvement of people's living standards, people have higher and higher requirements for the quantity and quality of timber utilization, and the contradiction between supply and demand of timber resources has become increasingly prominent. In recent years, people have modified wood to achieve high performance and improve the utilization of wood resources, thereby allevia...
