In the past week, temperatures in Beijing have gradually risen, and the weather has become dry due to lack of precipitation. Many people's homes, such as flooring, furniture and other solid wood products began to appear "crack".

At present, many families like to buy solid wood products, because solid wood is more natural and environmentally friendly than wood-based panels. But in a dry place like Beijing, cracking of wood products often plagues solid wood fans. When most manufacturers sell solid wood products, they usually point out that "cracking is caused by the nature of wood", and the phenomenon of cracking or even breaking during use is inevitable. However, some experts in the industry pointed out that solid wood cracking is not inevitable, as long as consumers pay more attention to the purchase, in the future use and maintenance, you can minimize the chance of solid wood cracking.

[furniture]

â—ŽCause analysis

Wood is not completely dry

If the manufacturer's wood is not dry enough, or if the drying time is insufficient for drying, it will result in different moisture content in different parts of the furniture. In the event of environmental changes, the furniture will crack under the influence of the stress remaining inside the wood.

Large changes in ambient humidity

Even if the wood is made into furniture, it will exchange moisture with the air in the environment and contract and expand with relative humidity. When the air is extremely dry, the furniture loses moisture and shrinks, and cracks may appear on the furniture surface. Conversely, when the humidity increases, the furniture absorbs the water and slightly expands, returning to its original state.

â—ŽPost maintenance

After excluding the quality of the product itself, it is necessary to make the solid wood furniture always fresh and long-lasting, and the cleaning and maintenance work is usually necessary.

Use a gentle rag to clean

Many people are worried about the dampness of solid wood furniture, often wiping the furniture with a dry rag. In fact, this approach makes it easy for the dust particles in the rag to scratch the lacquer of the furniture. It should be best to wipe with a slightly damp rag so that it can both replenish the water without damaging the furniture.

At the same time, when cleaning the surface of furniture, do not use chemicals such as alcohol, which will damage the paint surface of the furniture.

Regular oiling or waxing

When purchasing furniture, you should ask the manufacturer if the purchased solid wood furniture needs to be oiled or waxed. When the furniture is used for a period of time, it is recommended to do maintenance work once a month.

If you need to use waxing maintenance, it is best to buy a high concentration of solid wax, while maintaining the furniture, it can also fill in small defects on the furniture. In addition, spray wax is also a good choice. But the caveat is that the two can't be used together, because it will make the furniture surface no longer bright.

In addition, the newly bought solid wood furniture does not have to be oiled or waxed. Because the new furniture is fully protected before it leaves the factory.

[floor]

â—ŽCause analysis

Plate surface crack caused by drastic change in water content

Generally, the moisture content of solid wood flooring is affected by the environment. When the wooden floor is exposed to the sun or in an extremely dry environment for a long time, if the moisture content of the wooden floor is higher than the moisture content of the use environment, the floor will lose moisture and cause shrinkage, which is prone to cracks. According to reports, this crack appears in the end of the solid wood floor.

In addition to environmental factors, if the manufacturer does not fully dry the wood in the production process of solid wood flooring, so that the moisture content of the product is higher, even higher than the national standard limit, then when the solid wood floor is laid in a dry environment In the middle, large-scale cracking will also occur.

Improper paving leads to cracking

In the past, the flooring industry was talking about “three-point products, seven-point pavements”. In recent years, with the improvement and improvement of the production technology of flooring companies, experts in the industry have put forward the idea of ​​“one-point product and nine-point pavement”.

In the market, many installation workers are experienced in laying the floor. No matter what kind of wood is used on the floor, the moisture content and the actual use environment, the installation method and the reserved gap are the same. But in fact, this kind of empiricism is lack of scientific basis, often causing insufficient reserved seams. After the local plates absorb water vapor expansion, they will squeeze each other. When the pressure exceeds the compressive limit of the wood, the floor will crack. .

This cracking due to extrusion, the cracks appear more convex, and the crack interfaces overlap each other. At the same time, it can be observed that the solid wood floors are very tight, there is almost no gap, and individual floors may be deformed.

â—ŽPre-prevention

Selection of wood species based on the condition of the living environment

Due to the different materials used, the physical properties of solid wood flooring are different. When consumers purchase solid wood flooring, they should choose the type of wood to adapt to the environment of the living room. Because wood can be deformed or cracked due to changes in the environment. Generally, the humidity of the low-rise living room is relatively large. Therefore, when purchasing the floor, the wood with good stability should be selected, and the high-rise residential building is relatively dry, so the floor with a small shrinkage rate should be selected.

At present, there are many kinds of solid wood flooring materials on the market. The common domestic materials are eucalyptus, ash, birch, and maple. The imported materials include croton, merbau, balsam, heavy ant wood, teak, and eucalyptus. , iron wire and so on. Among them, merbau and teak are the most stable.

Try to choose narrow and short solid wood flooring

The smaller the size of the floor, the stronger its resistance to deformation and cracking. Try not to pick long and wide solid wood flooring when buying flooring. In terms of stability and service life, short is better than long, and narrow is better than width.

At present, the application of geothermal in the living room is more and more common. Although the solid wood floor is not completely unsuitable for the geothermal environment, the requirements for the geothermal floor are more demanding, and the thickness of the floor should not be too large. On the other hand, it is to reduce cracking and deformation. The chance, and more importantly, is to enhance thermal conductivity.

The moisture content of the floor should be similar to the local average moisture content.

Moisture content is one of the important factors that determine whether the floor will be deformed or cracked. Only when the moisture content of the purchased floor is close to the local average moisture content can the morphological change of the floor due to the change of water content be avoided.

According to national regulations, the moisture content is 8% to 12%. Generally, the average moisture content in the northern region is lower than in the south. If the moisture content of the solid wood floor is higher than the local average water content, the floor will gradually shrink and even crack; while the moisture content of the solid wood floor is too low, it will absorb the moisture in the environment, and the floor will expand and then squeeze, resulting in the floor. Cracking.

â—ŽPost maintenance

In addition to product quality, use environment and other factors, solid wood floor cracking is also related to the later maintenance.

Moderate hydration

When using solid wood flooring, be sure to keep the floor dry and clean. At the same time, it is also necessary to avoid prolonged exposure to the environment. In addition, if the environment is too dry, it is best to wipe the floor two or three times a week with a damp rag or use a humidifying device to moisturize the room.

When cleaning solid wood flooring, the floor should not be wiped directly with water or alkaline water, soapy water, etc., because chemical agents can damage the brightness of the paint and even damage the paint surface.

Regular maintenance

Taking proper maintenance methods will reduce the chance of cracking the solid wood floor and increase the service life of the floor. It is best to wax the floor or maintain the oil every three or four months, which will make the floor relatively "healthy", because wax or essential oil will form a protective film on the surface of the floor, reducing the impact of the environment on the floor.

In the past, many people thought that waxing was a time-consuming and laborious task, but at present, there are not only professional solid wood floor maintenance agents, but also related tools, and even the floor maintenance is simplified into two steps: “one spray and one wipe”. However, it is important to note that the floor should be cleaned before maintenance.

[wooden door]

Different from the floor and furniture, the wood door made entirely of solid wood is not the mainstream in the market. At present, the most contacted by consumers is the solid wood composite door. The surface layer of the solid wood composite door on the market is mostly composed of 5 mm thick medium density board and solid wood veneer. This structure effectively alleviates the deformation caused by the shrinkage of the wood, thereby greatly reducing the probability of cracking of the wooden door. However, experts caution that it is impossible to completely rule out the possibility of cracking. After all, wood will shrink or swell due to environmental changes.

In general, it is believed that mixed oil solid wood composite doors are more susceptible to cracking than clear oil doors. But in fact, this is a misunderstanding, just because the throttle is white, making the crack more obvious, and the clear throttle retains the original color and texture of the wood. Under the cover of the wood itself, the crack is not obvious. Our reporter Sun Tingting
