Solid wood doors have natural environmental protection characteristics, and solid wood doors are used more in home decoration. Solid wood doors use lignin, one of the main chemical components of raw wood, which has a strong absorption effect on ultraviolet rays. The fine unevenness of the wood surface structure can scatter light and reduce eye fatigue and damage. Next, I will introduce the reasons for the cracks of solid wood doors.

1. The moisture content of solid wood
If the moisture content of solid wood doors is not well controlled, quality problems such as cracking and deformation will occur. Therefore, it is very important to control the moisture content of solid wood doors, and the balanced moisture content will not crack and deform due to environmental factors such as sunlight, excessive cold, and excessive heat.
2. Caused by the weather
The weather in each region will be different, so the moisture content requirements of solid wood doors are also different. The average moisture content of southern air is 14%, and the average moisture content of northern air is 12% to 13%. Therefore, after the solid wood doors in the south are transported to the north, cracks will occur.
3. Improper use
Solid wood doors are not well maintained. Expose them to the sun or wipe the dust with a moist towel. This will affect the durability of solid wood doors.
