Mahogany furniture cracks, why? How to deal with it?

Mahogany furniture will crack because the process is not in place, and improper follow-up maintenance will also lead to cracking。After cracking, you can use sandpaper to polish the cracked place, and then collect all the fine powder from the grinding and put it in the crack, and finally seal it with glue and the crack. There are many reasons for the cracking of mahogany furniture, such as dry shrinkage and wet expansion, which can also lead to increased cracking.

When the air becomes dry, the furniture loses moisture and then shrinks. But when the humidity increases, the furniture absorbs moisture and swells. <>

There are three types of water in wood, such as free water, adsorbed water, and bound water. Free water is the water in the wood, and the change of free water has a lot to do with the density of the wood. Adsorbed water is the water that is present in the cell wall of wood.

When there is no water in the wood, the wood will dry out. At the same time, after the production of wood products is completed, the shape and material will not change, and the quality of wood products determines the force of wood at this time. <>

Furniture producers must know the moisture content of wood products so that they do not crack or deform the wood. After making furniture, it is necessary to test the moisture content and pay attention to quality in order to produce good wood. At the same time, mahogany furniture will have this phenomenon of cracking after being used for a period of time, which is normal.

However, if there are cracks in a large area, it is due to maintenance and quality reasons, which is an abnormal phenomenon. <>

Sometimes mahogany materials cannot be directly used to make furniture, because these materials need to be dried before processing, which is to avoid subsequent cracking of mahogany furniture. Because of the manufacturer's equipment and cost problems, this situation will occur when it is not dealt with in time. And mahogany furniture should never be exposed to the sun, which will make the furniture burst and reduce the service life of the furniture.

It is likely to be caused by too long use, or because the quality of the material is too poor, or it has been placed in a place with too high temperature for a long time, or it has been exposed to the sun. It should be remedied with some paints.

This is because the moisture in the furniture has evaporated, so it will crack, and this is where a repairer needs to be called in to repair the cracks.

Why does mahogany furniture crack

Generally speaking, it is relatively normal for mahogany furniture to crack, and there are many reasons for cracking, including the wood characteristics of mahogany furniture, production process problems and improper maintenance and use.

First, the properties of the wood itself. It is relatively normal for furniture to crack, and the same is true for mahogany furniture. The mahogany of ordinary mahogany furniture belongs to the dead cell tree, which will crack slightly, but will not burst.

Also, when the air dries, the furniture loses moisture and shrinks; When the humidity increases, the furniture absorbs moisture and expands slightly.

Second, the production process. When making mahogany furniture, there is an important process of drying treatment, which is an important step to avoid cracking of mahogany furniture. If the merchant does not have strict drying treatment due to equipment, cost and other problems, furniture cracking will also occur.

In addition, if the mortise and tenon structure.

If the process is not up to standard, the installation is not in place, and with the change of weather, external temperature and humidity, it will lead to thermal expansion and contraction.

The mortise and tenon structure will adjust and reset, which will eventually lead to cracking and bursting of mahogany furniture.

Third, improper maintenance and use of furniture. Improper use and maintenance of mahogany furniture will also cause cracking, such as in the cold season in the north, there is heating in the home, and mahogany furniture will be baked close to the heating for a long time, which will lead to cracking. In addition, in the hot summer, if the mahogany furniture is exposed to the scorching sun, it will also easily cause the mahogany furniture to burst and deform, thus affecting the service life of the wooden furniture.

Mahogany furniture restoration method

If you find that your mahogany furniture has cracks, the methods used are different for the different degrees of cracking of mahogany furniture. For example, if the cracking degree is small, it can be repaired by itself; If the cracking is large, it is necessary to have a professional person come to repair it. Below, let's take a look at the mahogany furniture restoration method with Zhenjiang mahogany!

If there are fine cracks or small cracks in mahogany furniture, you can use water to drop into the cracks for 7 consecutive days, and then use more than 1500 mesh sandpaper or fine cloth to wipe dry, clean, and finally paint or wax. It is worth noting that when painting, you must choose colorless and odorless environmentally friendly paint, apply it thinly once, polish it once, and repeat it four times; If you choose to wax, polish it with a muslin cloth and then wax it four times.

If there are small cracks or medium cracks in the mahogany furniture, you can use sandpaper to polish some mahogany fine powder and bury it in the cracks, with 502 glue.

Or seal it with chemical glue, and then wipe it dry with more than 1500 mesh water sandpaper or a fine cloth, and paint or wax it after drying.

If there is a medium crack or a large crack in the mahogany furniture, it is necessary to find a skilled and experienced professional to repair it, generally with a saw or knife or cut off the mahogany wood strips and repair them to the size of the crack. Then pour leather glue into the cracks, and then gently insert the leather glue-coated wood strips into the cracks. After the above operation is dried, it is polished or dried before being painted or waxed.

Cracking 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.

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.

Since real mahogany generally belongs to the dead cell tree, it will crack slightly, resulting in cracking of mahogany furniture. In fact, as long as it is made of real wood, it is normal for there to be slight cracking, and the same is true for mahogany furniture.

As long as the real mahogany furniture has undergone formal and strict drying treatment, the general cracking will not be obvious, and even if there is cracking, it is a very small crack, which usually does not affect the use. If the cracked gap is relatively large, the consumer had better contact the dealer to send a professional mahogany furniture maintenance master to repair the past, and if it cannot be repaired, it should be returned to the factory to replace the damaged parts.

If it is a quality problem, you can ask the manufacturer to repair it for free, the specific situation depends on the degree of cracking of the mahogany furniture and the warranty commitment when buying the mahogany furniture at that time.

Mahogany furniture is good when you buy it, why does it crack and deform? How should I take care of it on a daily basis? Generally, the wood has a moisture content, which is adjusted at around 12% or below.

The temperature and humidity of each place are all different, and the ambient humidity of the gas is important to determine the moisture content of the wood. For example, the average annual moisture content of timber in Beijing is 16% in Henan, and more in Wenzhou and Haikou. When a log comes into contact with gas, it digests and absorbs the water in the air.

Because the moisture content of the office furniture and the moisture content in the air are balanced, the drying gas will continue to absorb moisture from the furniture, and then both parties will reach equilibrium. In this case, of course, it will crack. Wood that does not crack does not exist, and even cement reinforcing bars will deform and close.

Generally, it is true that mahogany furniture belongs to the dead cell tree, which will crack slightly, but it is not easy to burst and crack through. Although the impact is not large, solid wood furniture usually needs to be maintained.

Many beginners come across cracks and talk to the store about the basic theory, saying that it is a defect. In fact, wind cracking is of course the process of wood release, and playing with wood requires the awakening of wood cracking. In general, the main reason is that due to the weather, the temperature and humidity of the home are different, resulting in the change of wood moisture content, so there will be cracking deformation.

Some people say that raising flowers, feeding fish, and installing an air humidifier at home to regulate the humidity of the environment can prevent wind cracks in furniture and artworks, and some people should avoid radiators when placing furniture, which is also reasonable. There is also an old player who said well, wood cracking is the natural survival state of raw materials, don't worry, you can ignore it, let it go, after years of tempering, you can look the attractiveness of the material itself.

Wooden features; As long as it is a furniture made of real wood, it is normal for a slight crack to occur, and the same is true for solid wood furniture, which is mostly made of precious mahogany furniture, and the characteristics of wood are like this, and the wood that does not crack does not exist. Generally, it is true that mahogany furniture belongs to the dead cell tree, which will crack slightly, but it is not easy to burst and crack through.

It may be caused by improper care after you buy it, if it is in a humid or very dry environment for a long time, it will crack and deform; In daily life, we must do a good job of maintenance, try to put it in a place with better air, and choose a special cleaning liquid for furniture to wipe when wiping, so as to avoid the usual collision.

Mahogany furniture has the wood properties of "dry shrinkage and wet expansion": when the air is extremely dry, the furniture loses moisture and shrinks. Conversely, when the humidity increases, the furniture absorbs moisture and expands slightly.

Improper maintenance can also lead to cracking of furniture, when heating is used in winter, wooden furniture is baked close to the heating for a long time, or exposed to the scorching sun in summer, etc., can easily cause wooden furniture to burst and deform.

First, the placement of mahogany furniture should not be close to the wall, especially for northern friends with floor heating at home, the furniture should be kept away from the heating system, and the furniture should be cushioned with floor heating at home, not placed in front of the air conditioner and sunlight, and avoid direct sunlight.

The second balance of wood moisture content, in summer, properly close the curtains, to avoid furniture exposure to the sun, in winter to open the humidifier appropriately, do not open the window for a long time to ventilate, the dry and cold north wind will accelerate the volatilization of moisture in the furniture, indoor fish can also be raised, a few cases put some green plants, increase the indoor humidity, so that the air will absorb these moisture.

This is because the air is relatively dry, or it may be caused by improper use, so it must be maintained on time and waxed on time in daily life.

Mahogany furniture is relatively expensive, and when purchasing, you must consult the merchant how to maintain it, and you need to clean it with a special detergent. After cracking and deformation, you can apply for after-sales.

Why does mahogany furniture crack, the truth is here!

Hello dear, why does mahogany furniture crack, the truth is here! 1. Caused by the characteristics of wood. As long as it is made of real wood, it is normal for slight cracks to occur, and the same is true for mahogany furniture.

Although mahogany furniture is mostly made of precious mahogany, the characteristics of wood are such that there is no such thing as wood that does not crack. Generally, mahogany will crack slightly, but it will not burst or crack, and it can be restored to its beauty with a little repair. 2. Temperature difference and water content.

The material of mahogany furniture is the most natural and has a certain activity, which can expand and shrink with the change of ambient temperature. When the temperature of the surrounding environment increases, the kinetic energy of wood molecules increases, and the average free path of the molecules increases, so it is manifested as thermal expansion; In the same way, when the temperature of the surrounding environment decreases, the kinetic energy of the wood molecules decreases, and the average free path of the molecules decreases, so it manifests as cold contraction. Therefore, placed in an environment with a large temperature difference, due to the influence of temperature, the panel will move in the expansion space, so there will be a phenomenon of inconsistent dimensions on both sides of the expansion joint, which looks like "cracking", which is actually a normal phenomenon.

The main reason for the cracking and deformation of mahogany furniture is the imbalance between the moisture content of mahogany and the moisture content of the external environment. The equilibrium moisture content of timber varies with the different regions where it is located, about 12 in the north of China, about 18 in the south, and 15 in the Yangtze River basin.
