The role of moisture content in sports wood floors
Manufacturer hotline: 13718418469/13811196760 Li Yong
As we all know, as long as it is a solid wood sports floor, it will contain a certain amount of moisture. The moisture content of the sports wood floor panel and keel has always been an important factor affecting the quality of the entire sports ground. After the solid wood sports floor is processed, the shape and material will not change. At this time, the key factors that determine the inherent quality of the solid wood sports floor are mainly is the wood moisture content and drying stress. When the solid wood sports floor reaches the equilibrium moisture content when it is used, the solid wood sports floor at this time is not easy to crack and deform.
After the trees are cut down to make wooden floors, although they do not have the function of oxygen production, they have the characteristics of regulating indoor air humidity and temperature. In order to seek its own equilibrium moisture content, wood will absorb or release moisture in response to changes in the moisture content of the surrounding air. Therefore, it is not that the lower the moisture content of the solid wood sports floor, the better. If the moisture content of the solid wood sports floor is too high, after the decoration, affected by the dry weather, the moisture in the floor dries up and shrinks, and a seam will appear between the floors. If the moisture content is too low, the expansion gap is not enough during decoration, the weather is humid, and the floor will arch and warp when it is damp. The moisture content of wood floors varies due to the different characteristics of the tree species and different geographical locations. Under the condition that the characteristics of the tree species cannot be changed, reasonable "health" (a process of adjusting the moisture content of the wooden floor and other properties), so that the moisture content of the wooden floor is consistent with the local average moisture content, has become the key to ensuring the stable moisture content of the wooden floor. .
When wood is exposed to air with a certain humidity and relative humidity for a long time, it will eventually reach a relatively constant moisture content. At this time, the speed of moisture absorption and dehumidification of wood is equal. At this time, the proportion of wood moisture content is called equilibrium moisture content. . This stable moisture content state is determined by the relative humidity of the surrounding air, as well as the temperature and the dryness and wetness of the wood. For example, the average annual equilibrium moisture content in Guangzhou is 15.1%, while that in Beijing is 11.4%. Floors dried to 11% are suitable for use in Beijing, but for Guangzhou, they will absorb moisture and expand, resulting in deformation. On the other hand, if the moisture content is suitable in Guangzhou, it may cause dry cracks in Beijing. Therefore, different regions and different uses have different requirements for the moisture content of the floor. To judge the moisture content of solid wood sports flooring, it should be adjusted according to the local conditions, and remember not to mix and match at will.
Therefore, we will seal the panel during transportation of the wooden floor to the site. After arriving at the site, we will remove the sealing film to allow the panel and keel to reach the local equilibrium moisture content, and use our pre-controlled wood moisture content to effectively control the performance of our sports wooden floor. The overall expansion and deformation can ensure the quality of the sports wood floor and give customers a satisfactory project!
