Abstract

The invention discloses a method for improving the dimensional stabilization of wood. The method comprises the steps of soaking wood in petroleum wax, carrying out soaking process on the wood and making wood absorbing petroleum wax to obtain wood with good dimensional stabilization. According to the method, wax injection process is carried out on the wood in the normal pressure condition, and the petroleum wax is injected into the wood on the premise without damaging performance of the wood. Thus, redundant moisture in the wood can be drained out. Meanwhile, pipe holes of the wood and gaps between cells can be sealed, and the purpose of improving the dimensional stabilization of the wood is achieved. Furthermore, the method is simple in equipment, convenient to operate, controllable in processing condition and suitable for processing various kinds of wood.

Description

technical field

[0001] The invention relates to a wood treatment method, in particular to a method for improving the dimensional stability of wood. Background technique

[0002] Wood is mainly composed of cellulose, hemicellulose and lignin. There are a large number of hydroxyl groups on the cellulose and hemicellulose molecules, so that the moisture inside the wood will change with the change of ambient temperature and humidity, and the moisture inside the wood will change. In the process of desorption or moisture absorption, the wood will shrink and swell, making the wood swell and shrink unevenly with the change of wood moisture content in all directions, and it is easy to produce warping, deformation, cracking and other defects, which restricts the application range of wood. Therefore, improving the dimensional stability of wood is of great significance to the efficient utilization of wood.

[0003] In order to improve the dimensional stability of wood, many scholars ha...
