<p>the wood floor, we must pay attention to the level of its moisture content. Below we learn more about the classification and specifications of the floor moisture content. First, the classification of the floor moisture content 1, water content of the board moisture content of the floor material contained in the weight of water and dry flooring percentage of the weight of the material. 2, the balance of </p>
<p>moisture content of the board material in the floor under certain air conditions, the final moisture absorption or desorption of stable moisture content, called the equilibrium moisture content of the floor material (floor moisture stable state). Second, the floor moisture content of the specification of the floor is the more dry the better? Floor material placed in a certain environment, after a long enough </p>
<p>time, the moisture content tends to an equilibrium value, known as the equilibrium water content of the environment EMC. When the moisture content of the floor material is higher than the equilibrium moisture content of the environment, the floor material will wet shrinkage, otherwise it will hygroscopic expansion. For example, the average annual equilibrium moisture content in Guangzhou is </p>
