Why does the wooden furniture I buy sound when I buy it?

There are many specific reasons for the sound of furniture, and it is not necessarily the quality of the furniture, and it has to be analyzed.

1. The sound of hardwood furniture swelling with the change of seasons and humidity is a normal natural phenomenon. This is particularly evident in the lead ridge of freshly made furniture that has just left the factory. The pants are round.

2. If the wooden furniture is disassembled and repaired regardless of the new or old, there is also a process of re-adapting to the environment, which will also produce noise.

3. It is normal for old furniture to be transported from place A to place B, even if it is the same city, due to changes in the surrounding environment.

4. The furniture from the south is transported to the north or the furniture from the north is transported to the south, and there is a process of adaptation and sound.

There are sounds caused by normal reasons, and there are sounds caused by abnormal reasons, which are basically caused by insufficient drying of wood or too high moisture content and improper processing technology, and the sound caused by insufficient reserved gaps between parts.

Normal causes:1It is normal for hardwood furniture to swell with the seasons and humidity. This is especially evident in the freshly made furniture that has just left the factory.

2.Hardwood furniture, whether new or old, will also have a process of re-adapting to the environment if it is disassembled and repaired, and it will also make noise.

3.It is normal for old furniture to be transported from A to B, even if it is in the same city, and it is normal for it to make noise due to changes in the surrounding environment.

4.Furniture from the south to the north or furniture from the north to the south, there is a process of adaptation that produces a sound.

Generally, the sound will not last too long, 2-3 months or half a year, but especially rosewood and sour branch wood may last a little longer, as long as there is no explosion of large edges or other parts, and cracking of mortise and tenon joints is normal. Veneered furniture, wood-based panel furniture, cork furniture or steel-plastic furniture, marble furniture will not make a sound.

There are many specific reasons for the sound of wooden furniture, and it is not necessarily the quality of the furniture, but also has to be analyzed.

1. Normal reasons:

Clause. 1. The sound of hardwood furniture swelling with the change of seasons and humidity is a normal natural phenomenon. This is especially evident in the freshly made furniture that has just left the factory.

Clause. 2. Hardwood furniture, whether new or old, if it is disassembled and repaired, there is also a process of re-adapting to the environment, which will also produce noise.

Clause. 3. It is normal for old furniture to be transported from place A to place B, even if it is in the same city, due to changes in the surrounding environment.

Clause. Fourth, the furniture from the south is transported to the north or the furniture from the north is shipped to the south, and there is a process of adaptation and noise.

Generally, the sound will not last too long, 2-3 months or half a year, but especially rosewood and sour branch wood may last a little longer, as long as there is no explosion of large edges or other parts, and cracking of mortise and tenon joints is normal. Veneered furniture, wood-based panel furniture, cork furniture or steel-plastic furniture, marble furniture will not make a sound.

2. Abnormal causes.

Clause. 1. The sound caused by improper drying of wood or excessive moisture content of wood and serious expansion and contraction;

Clause. Second, the wide parts of hardwood furniture have a large amount of expansion and contraction, such as the surface of the square table will reach about 2mm, and the surface of the case will reach about 1mm. Therefore, in the production of hardwood furniture, the board surface, stool surface, counter surface, desk surface, and tapering board must be left with appropriate expansion joints to ensure its normal swelling.

If the bulging position is too tight; Or in the place where glue should not be used (including fish bladder), or the size is not properly matched, in the season of large humidity changes, the relative movement between the panel spring and the large side slotting will occur, coupled with the poor production process, the groove is too heavy on the squeezing of the spring, when the wood stress is released, the two will produce a large sound. If the staggered part is glued, the huge stress of the wood cannot be released, and the glue cracks or the panel breaks.

It is now winter, the wooden furniture bought back is outdoors during transportation, the air temperature is relatively low, at this time it will undergo thermal expansion and contraction, when moving into the room is your home, the ambient temperature rises, at this time the cold shrinkage wood will expand, at this time it will make a sound, which is a normal phenomenon.

This winter, the cold and heavy snow are wet, especially the air humidity is damp and dry. Yesterday, the humidity in the southern provinces was 75%-80%, and today, it is 35%-40%. This humidity is very unfavorable to solid wood, with the rapid change of air humidity, solid wood will dry and crack, making a "pop, pop" sound.

There is a problem with the tenon.
