Anonymous users2024-01-24Cracking of wood is a normal phenomenon, and it is not normal to prevent it from cracking. And all of our methods are changing the normal situation. When you understand this, you may feel a lot calmer when you encounter cracking.
Generally, wood has a moisture content, which is controlled at about 12% or below. The temperature and humidity are different in different places, and the humidity of the air is the key to determining the moisture content of wood. For example, the average annual moisture content of timber in Beijing is 16% in Shanghai, and it is higher in Wenzhou and Haikou.
When wood comes into contact with air, it absorbs moisture from the air.
In order to equilibrium the moisture content of the furniture and the moisture content in the air, the dry air continuously absorbs moisture from the furniture, thus bringing both sides into equilibrium. In the process, cracking is natural.
There is no such thing as wood that does not crack, and even the cement steel bars will deform and shrink. Generally, real mahogany is a dead cell tree, which will crack slightly, but will not explode or crack through. Although the impact is not large, mahogany furniture usually pays attention to maintenance.
Many novices encounter cracks and theorize to the merchants, saying that they are flaws. In fact, wind cracking is a natural process of wood release, and playing with wood is the consciousness of wood cracking. In general, the main reason is that because of the climate, there are differences in temperature and humidity at home, which leads to changes in the moisture content of wood, so there will be cracking and deformation.

Anonymous users2024-01-23Cracking of mahogany furniture is a normal phenomenon. Mahogany furniture wood contains water, is active wood, when the air humidity is too low, mahogany furniture will shrink, too high will expand, the natural properties of mahogany make it crack! When the ambient humidity of the furniture exceeds the moisture contained in the furniture components, the moisture inside the furniture is less, and the moisture is absorbed during the breathing process, so all parts of the components will rise due to the increase of moisture; Otherwise, the component will shrink.
No matter how dense the wood is, no matter how dry the environment is, there will still crack and make cracking sounds. The internal structure of mahogany furniture undergoes small movements with time and environmental changes. For example, when assembling mahogany furniture, the mortise and tenon structure may not be fully installed in place for some reasons, or there is a certain dislocation and competition, so after a period of time, due to the change of temperature and humidity, thermal expansion and contraction, the mortise and tenon structure is self-adjusted to reach the due position with the help of force, and there is a cracking sound.
It is normal for mahogany furniture to have slight cracks. The mahogany furniture that has just been delivered has a lot of cracks and should contact the dealer for replacement. >>>More
It's not normal, if it's paint cracking, it means that when the manufacturer is processing this furniture, 1 is sprayed less times, resulting in a little high temperature on the opening, 2 if it's wood, it means it's definitely not mahogany, because the wood of mahogany is very tight, even if it's a damp mahogany, the possibility of opening in the sun is very small, no matter what the situation, you have to ask for a return.
Mahogany furniture cracking repair method.
Generally, mahogany furniture will have expansion joints, because wooden furniture usually has the phenomenon of thermal expansion and cold contraction, if there is no expansion space, it is easy to cause cracking and deformation of furniture. Many people will ask how to repair the cracking of mahogany furniture, and the methods of repairing the cracking are divided into four categories: fine, small, medium and large. >>>More
Fine crack and small crack repair method.
Water can be used to drop into the crack for 7 consecutive days, using the inherent characteristics of wood shrinkage and swelling, cracks and water swelling, fine lines will heal naturally within 7 days, and then polish with more than 1500 mesh water sandpaper, wipe dry and wipe with a fine cloth, and then paint and wax. Paint should choose colorless and odorless environmentally friendly paint, apply thinly once, polish once, and repeat four times. The waxing is also done four times, but it should be wiped with a fine cloth instead of sandpaper. >>>More
Real mahogany furniture can not use glue and iron nails, and the reason why those Ming and Qing dynasty furniture can still be preserved after a hundred years is because it is pure mortise and tenon. Because the glue is only effective for a few years, after a few years the glue fails, and the furniture falls apart, and it cannot be repaired. Now the use of glue for furniture is time-saving and labor-saving, like cutting corners, the general trend.
