In the winter, families who have laid solid wood flooring should pay more attention to it at this time. In winter, it is the high season of â€œaccidentâ€ in solid wood flooring. The winter climate, especially in northern China, is relatively dry, and problems with solid wood flooring are also common at this stage. Although the southern climate is relatively not so dry, due to the large use of heating equipment, the indoor environment will also be relatively dry and low humidity.
This has buried hidden dangers in the "accidents" of the floor. As a user of the use, it is necessary to know the characteristics of the solid wood floor and the common sense of the floor to avoid the occurrence of "accidents" and to maintain the best condition of the floor.
In winter, the indoor climate is dry, and the common "accidents" of solid wood flooring are often seen as dry shrinkage, end cracking, warping, distortion, etc., and local appearance of lacquer cracks and creases appear. The phenomenon of shrinkage and deformation will form a clear gap, which will easily invade the dust and become a sanitary corner of the dirt. Not all of the above phenomena are production quality problems. Although the quality of production plays a crucial role in the state of the product during the period of use, the "quality" and human factors of the living environment can not be ignored.
Users who lay the floor during the year must be aware of the various factors that cause the problem. Under the premise of paving according to the installation rules of solid wood flooring, the above-mentioned "accidents" appearing on the solid wood floor during the use period should be analyzed to know ourselves and prevent problems:
Gap caused by shrinkage
The main reason is that the environment is dry, the wood is caused by shrinkage, and warping and distortion may occur at the same time. The reason is that the use of environmental factors bears the brunt, the use of environmental indicators "exceeds the standard", the temperature is too high, the environment is dry, the relative humidity of the air is less than 30%, resulting in floor water loss, shrinkage, forming a clear gap, and forming a single plate in the local Quc and other phenomena; the two, the factors of the floor material itself, the special structure of the wood, the selection of materials and other factors, caused by the change of wood moisture content after shrinking and twisting, forming a clear gap; three of them, the quality of the floor production, production process The control of the moisture content of the floor plays a decisive role. The moisture content exceeds the standard, and the water is lost after the floor is paved. The fourth is the floor product specification factor, the wider the veneer specification, especially after the moisture content changes. The larger the gap created by the shrinkage.
End crack caused by shrinkage
The crack at the end of the solid wood floor is caused by the difference between the moisture content of the floor and the water content of the environment, the actual moisture content of the floor is higher than the equilibrium moisture content of the environment, and the water loss at the end of the floor is too fast and the stress caused by the sharp contraction is caused. The end crack.
End cracks are common in solid wood floors with high density and high hardness. The dryer the air in the environment, the greater the degree of cracking at the end of the floor. The humidity in the environment is increased and the cracking of the floor is gradually reduced.
Cracking of paint surface caused by shrinkage
In the physical and mechanical properties of solid wood flooring, there are clear standards for the performance of the paint surface, such as abrasion resistance, paint adhesion, paint film hardness and floor moisture content. After the moisture content of the floor is changed, The lacquer surface is inconsistent with the wood shrinkage rate, and the paint surface is affected by wrinkles, cracks, enamel paint and the like.
The above-mentioned various phenomena are nothing more than the reasons for the use of environmental standards and the quality of the floor. If the gap exceeds 2mm, it needs to be repaired. If the dry shrinkage is less than 2mm, it will not need to be repaired. After the winter, it will return to normal. The quality is not enough to hold the responsibility of the producers and sellers. The user should also maintain the floor in time, "lock water, moisturizing", and stay in the beautiful "face" of the floor. Properly increasing the relative humidity of the use environment can reduce the gap created by the shrinkage of the floor. Users should carry out humidification treatment to keep the relative humidity of the air balanced and temperature balanced. It is recommended to use natural resin essential oil or special floor wax to maintain the board surface and form a protective film on the surface of the floor, which not only increases the luster and beauty, but also locks it. The moisture of the wood is more inorganic and toxic. In winter, the indoor humidity is best controlled at about 50%, which not only controls the occurrence of floor shrinkage and distortion, but also benefits human health and wooden household items.
From the production point of view, the size of the gap between the floors is closely related to the shrinkage factor of the wood used for the floor, the moisture content of the floor, the equilibrium moisture content of the use environment and the width of the floor. The greater the coefficient of shrinkage of the wood material, the greater the probability of deformation with the change of water content, and the greater the difficulty of processing. At this time, the quality of the product and the quality of the service are particularly important, and the advantages and disadvantages of the extended service are also known.
