There are many specific reasons for the sound of hardwood furniture, not necessarily the quality of furniture, but also specific analysis.
First, the normal reason:
First, the sound of the hardwood furniture that swells with the change of season and humidity is a normal natural phenomenon. What is particularly evident is the new furniture that has just been manufactured.
Second, hardwood furniture, no matter how old or new, if it is re-disassembled for repair, there will be a process of re-adapting to the environment, and it will also produce a sound.
Third, the old furniture is transported from the A to the B, even if it is the same city, it is normal to produce a sound due to changes in the surrounding environment.
Fourth, the furniture that is transported to the north or the north by southern furniture is shipped to the south, and there is a process of adaptation that produces a sound.
Generally speaking, the duration of the sound will not be too long, 2-3 months or half a year, but especially the rosewood and rosewood may last longer, as long as no big edges or other parts burst, cracking, All are normal. Leather furniture, wood-based panel furniture, cork furniture or steel-plastic furniture, marble furniture will not produce a sound.
Second, abnormal reasons:
First, the sound produced by improper drying of the wood or the excessive moisture content of the wood;
Second, the large parts of hardwood furniture have a large amount of expansion and contraction. For example, the surface of the square table will reach 2m 2 or so, and the surface of the case will reach about 1m 2 . Therefore, in the production of hardwood furniture, the board surface, the stool surface, the cabinet surface, the surface of the case, and the annulus plate must have appropriate expansion joints to ensure their normal expansion. If the expansion position is too tight; or if glue (including fishing rods) should not be used in the place where the glue should be used, or the size is not properly matched, the relative between the panel spring and the large side groove will occur in the season when the humidity changes greatly. Movement, coupled with poor manufacturing process, the slot is too heavy to squeeze the spring, when the stress of the wood is released, the two will be louder. If the misaligned part is glued, the huge stress of the wood cannot be released and the glue will crack or the panel will break.
Therefore, the reason for the sound of hardwood furniture should be analyzed in detail, so as not to affect the shape, use and cracking of furniture.
