Anonymous users2024-01-23The national standard stipulates that the moisture content of wood flooring is 8%-13%. In fact, China has a vast territory, and the moisture content requirements in different regions are different. The floor moisture content in the northern part of China is 12%, and the floor moisture content in the southern region should also be controlled within 14%.
Generally, the dealer of wood flooring should have a moisture content tester, if not, it means that the moisture content is not paid attention to. China wood flooring network reminds that when purchasing, first test the moisture content of the wood floor selected in the exhibition hall, and then test the moisture content of the wood floor of the same material and the same specification that has not been opened, if the difference is 2%, it can be considered qualified.

Anonymous users2024-01-20The moisture content stipulated by the state is 8%-12%, which needs to be adjusted according to the local environment, the coastal areas are humid all year round, and the moisture content will be relatively high, and the northwest region has a dry climate all year round, and the moisture content is relatively low. Sports wood flooring wood is placed in a certain environment, and after a long enough time, its moisture content will tend to an equilibrium value, which is called the equilibrium moisture content EMC of the environment. When the moisture content of the wood is higher than the equilibrium moisture content of the environment, the wood will shrink due to moisture discharge, and vice versa, it will absorb moisture and expand.
Therefore, the wood drying of sports wood flooring should be appropriate, not the drier the better. Different regions and different uses have different requirements for wood moisture content.
