Careful observation of solid wood furniture will reveal a small seam in many parts of the furniture. Many consumers who don't understand the situation may think that this kind of scum-like gap affects the appearance and is caused by mistakes in the design of the furniture. In fact, this is a way that manufacturers can't do it.
This slit has a technical term called"Expansion seam". Solid wood furniture, especially mahogany furniture, will be specially reserved for expansion in order to adapt to different environments.0.3-0.5Within centimeters. If the panel is not too wide, the expansion joints are more than0.5The centimeter may be caused by the fact that the wood is not dried when the furniture is made.
Expansion joints can be described asrealWooden furniture"Self-protection system." high qualityrealThe wooden furniture emphasizes the structure of the enamel structure. Instead of using a nail, the various parts of the furniture are assembled by a clever combination of enamel and enamel. The function of the expansion joint is that when the wood shrinks or expands due to environmental influences, the structure of the concrete is not damaged, and the components of the furniture are loosened and cannot be used normally.
It can be seen that the expansion joint is in the containment of wood.The physical characteristics of "thermal expansion and contraction" have greatly protected the life of solid wood furniture. So if atrealI saw these expansion joints on the wooden furniture, so I don't have to worry too much.
In the spring and winter, when the furniture is dried by wood, it is generally necessary to leave the expansion joint. Otherwise, after the wet summer arrives, the big side will rise and fall. On the contrary, the materials dried in the winter will be installed again after the end of the year. Although they can be installed together, the season of the rainy season will definitely rise. Unless it is made in a place where the humidity changes little in the four seasons, it is used locally. There are also different materials that are different in nature..
The material of solid wood furniture is the most natural and has certain activity. It can expand and contract with the change of ambient temperature. It is life, body temperature and fresh humanity. Therefore, different seasons are related to shrinkage joints.
The material characteristics determine the size of the shrinkage joint: the expansion joint is ubiquitous in the furniture of the Ming and Qing Dynasties. Generally, the furniture of Ming and Qing Dynasties have expansion joints, especially the combination of the grooved plate and the slats, which cannot be separated from the expansion joints, such as the ring plate. Cabinet door, chair, table, case, etc. The purpose of the expansion joint is to prevent the frame or corner of the furniture from being cracked; the highest standard for retaining the expansion joint is that the board moves to no expansion joint when the air is wet, and does not crack the frame.
In order to reduce the deformation of the wood, the wood has a strict drying process before it is made into furniture, and some may be baked for more than a month. In order to control the quality of the regulated manufacturers, the water content of products sold in different regions is also different. Even so, in order to prevent furniture deformation, expansion joints must be reserved, and some technically good manufacturers are more secretive, it seems that it is a decorative gap.
And some manufacturers do not leave expansion joints for solid wood furniture. It does not mean that there is no such thing. Because the manufacturer does not have absolute control over the drying of the wood, the moisture content of the wood is generally higher than the moisture content of the air, so that even if the expansion joint is not left during the production, the furniture will be seamed after the finished production.
The expansion joint plays an important role in improving the service life of solid wood furniture. It is solid wood furniture."Self-protection system." Moreover, in most cases, there is no need to worry about the unevenness of the expansion joint size, and most of the original changes will be restored after the season change.
