The raw materials of mahogany furniture are more expensive. Experts pointed out that in the drying of mahogany, the quality of drying and the reduction of the loss should be the primary consideration. To achieve these two points, scientifically mastering the drying process is the most important prerequisite.
Fresh mahogany wood contains a lot of water, which will evaporate under certain circumstances. The natural evaporation of water can cause defects such as shrinkage, cracking, bending deformation, mildew, etc., which seriously affect the quality of wood products. Therefore, wood must be dried before being made into mahogany furniture. If it is not dry properly, there will be various problems in the subsequent processing, assembly and painting of parts, thus affecting the quality of the finished product. Proper drying can overcome the above-mentioned wood defects, improve the mechanical strength of the wood, improve the processing properties of the wood, and extend the service life. It is an important technical measure for rational use and saving of wood, and is an indispensable important process in wood processing and production.
Mahogany furniture
Special top-grade mahogany black rosewood, Vietnamese huanghuali and lobular rosewood are wood, all are hard-to-dry hardwood, the moisture in the mahogany moves very slowly, the water passage in the wood is not smooth, so the surface layer and the lower part of the inner layer The water content varies greatly. In the process of wood drying, in order to improve the drying speed of the wood, eliminate the stress during the drying process, and alleviate the water content gradient, the final moisture content of each plate of the balance material pile needs to be separately preheated, intermediate, Balanced and finished processing and other processing.

The external factors affecting the drying of wood are the temperature and humidity of the drying medium, the circulation velocity of the air flowing through the surface of the wood and the pressure of the medium; the internal factors are mainly the tree species, the thickness of the dried wood and the initial moisture content. In the case where the drying equipment in each part of the drying chamber can ensure normal working conditions, the wood drying process conditions are the key to ensure the wood drying cycle and the quality of wood drying.

Wood drying benchmarks are one of the important benchmarks for guiding wood drying production. The mahogany timber species are relatively single. After understanding and mastering the dry quality and final moisture content required for the dried wood, the corresponding drying process conditions can be selected. The core content is to select the drying basis and determine the heat and humidity treatment conditions according to the tree species and thickness of the dried wood. Improve the drying speed under the premise of ensuring the quality of wood drying, save energy consumption, reduce drying costs, and produce maximum economic benefits.
The core content of the wood drying process conditions is the wood drying standard. The softness of the drying standard basically determines the wood drying cycle and the wood drying quality. Therefore, the cracking, deformation and uneven moisture content of the wood during the drying process are all Wood drying defects caused by wood during the drying process. Among them, cracking is also called dry cracking, which includes end cracks, surface cracks and internal cracks; deformation includes smoothing, transverse bending, warping and twisting.
The application of modern drying technology to research and improve the dry quality of mahogany furniture materials, the improvement of the quality of mahogany furniture products, is essential for stabilizing and expanding the domestic and domestic market share of mahogany furniture. It is of great significance to promote the development of Chinese traditional furniture in the promotion of mahogany culture. Studying and improving the dry quality of mahogany furniture materials is a basic technical input necessary for the redevelopment of mahogany furniture enterprises, and also a prerequisite for capacity building.
