When you buy wooden flooring, you tend to focus on the price of the floor, styles, colors and other issues that are easy to notice, often overlooking some very small problems. In some households, the wooden floor will be installed with cracks, deformations and other quality problems. Why is the beautiful wooden floor after the installation is cracked after a period of use? This is the moisture content of the wooden floor.

Experts believe that no matter whether it is solid wood flooring or solid wood composite flooring, as long as it is made of natural materials, it will contain a certain amount of moisture. After the production of wood products is completed, the shape and material will not change. At this time, the key factors determining the intrinsic quality of wood products are mainly the moisture content and dry stress of the wood floor. When the wood product reaches an equilibrium moisture content when used, the wooden floor at this time is the least susceptible to cracking.

Wood floor moisture content: The percentage of the moisture content of the wood floor and the weight of the wood floor after drying.

Balanced moisture content of wooden floor: The moisture-stable stable moisture content or desorption-stable moisture content of the wooden floor under certain air conditions is called the equilibrium moisture content of the wooden floor (the moisture level of the wooden floor).

So what is the water content that is qualified?

Is the wooden floor better? The wooden floor is placed under a certain environment. After a long enough time, the moisture content will tend to an equilibrium value, called the equilibrium moisture content EMC of the environment. When the moisture content of the wooden floor is higher than the equilibrium moisture content of the environment, the wooden floor will be wetted and contracted, and vice versa. For example, the average annual equilibrium moisture content in Guangzhou is 15.1%, compared with 11.4% in Beijing. Drying to 11% of the wooden floor is suitable for Beijing, and it can be used for Guangzhou to absorb moisture and deform. Conversely, if the water content in Guangzhou is suitable for Beijing, there is a possibility of chapped. Different areas, different uses, the requirements for the moisture content of wood floors are also different.

For solid wood flooring, solid wood composite flooring, bamboo flooring, etc., which are made of natural materials, it is the ideal way to adjust the moisture content after 2~3 days in the site after unpacking. Do not directly dry the ground without drying it.
