Moisture content of solid wood flooring How much moisture content is the best moisture content of th

The moisture content of solid wood flooring should be adapted to the local humidity and the balanced moisture content of local wood. The moisture content of the same floor of a good brand in different regions is not the same, and the floor must be vacuum-sealed packaging to prevent deformation during transportation, and it will generally be opened one day in advance to adapt to the environment at home when installing, so as to lay a good foundation for installation and prevent violent shrinkage and expansion due to temperature, humidity and other reasons.

When the moisture content of the wood floor is lower than or equal to the equilibrium moisture content of the local wood. The problem is not very big, the wooden floor will slowly absorb moisture, provided that the difference is not very large, if the difference is large, the early stage does not adapt to the environment, and the installation is relatively tight, the floor may arch.

If the moisture content of the wood floor is higher than the equilibrium moisture content of the local wood. Wooden floors will slowly release moisture, and over time, the floor is prone to dry and crack. That's why solid wood furniture in the north, solid wood floors are more prone to dry cracking.

Below the balance moisture content of the wood in various places.

1. Requirements for moisture content of sports wood flooring.

According to the requirements of the industry, the moisture content of sports wood flooring should reach a balanced moisture content. Generally between 6% and 14%. If the moisture content is too small, the sports wood floor will dry and crack; If the moisture content is too large, problems such as damp arching and deformation of the sports wood floor will occur.

The moisture content of sports wood flooring should be adapted to the climate and humidity of the stadium.

2. The problem of excessive moisture content.

Some small workshops of sports wood flooring in the sports wood flooring market, the material is not dried, and it is stacked in the open air at will, and the moisture content of the material varies greatly. In the same batch of materials, some have a moisture content of about 10, and some are as high as 25 or more.

Even if the installer finds the material very flat, the sports wood floor may not sound for the time being after installation, and in the process of use, after the moisture content of the material is rebalanced, there will be unevenness, and walking on the sports wood floor will produce a sound. It doesn't ring when it is installed, but it rings after a period of use. There are not many areas where the sound is generated.

3. What should I do if the moisture content is too large?

Brand sports wood flooring manufacturers, will dry the sports wood flooring material, and some dealers take the finished material, temporarily do not install the sports wood floor, put it for about a week, re-leveling and then paving, can reduce the probability of such problems.

Solid wood flooring is paved to many stadiums and construction sites, what is the appropriate moisture content of solid wood flooring? Expertise in the moisture content of solid wood floors:

1. The form of moisture in solid wood flooring

There are three forms of water contained in solid wood flooring, one is the water that exists in the cell cavity and the intercellular space, that is, the water that exists in the capillaries, which is called free water. The second type is water that is absorbed by the cell wall, which is called adsorbed water. The third type is the water that makes up the tissue of the cells, known as chemical water.

2. Moisture content of fiber saturation point

When the moisture of the damp solid wood floor evaporates, the first thing lost is the free water, and the moisture content when the free water evaporates and the adsorbed water is still in a saturated state is called the moisture content of the fiber saturation point.

The fiber saturation point is the turning point of the performance of solid wood flooring, above the fiber saturation point, the strength of solid wood flooring is constant and does not change with the change of moisture content. At the same time, there is no change in the volume of solid wood flooring. When the moisture content drops below the fiber saturation point, that is, when the adsorbed water in the cell wall begins to evaporate, the strength increases with the decrease of the moisture content, and the phenomenon of wet expansion and dry contraction is also obvious.

The moisture content of different solid wood flooring fibers is about 22% and 33%.

3. Moisture content at the balance point of the floor

The humidity and temperature in each region of nature are relatively stable in different seasons. Solid wood flooring is in this relative temperature and humidity environment for a long time, and its moisture content will reach a relative constant. At this time, the moisture content is called the equilibrium moisture content (for example, the annual equilibrium moisture content in the Shanghai area.

The equilibrium moisture content of solid wood flooring varies with the temperature and humidity of the environment in which they are located, and when there is a difference between the equilibrium moisture content and the ambient humidity, it tends to be close to the environment. This results in the phenomenon of wet expansion and dry contraction of solid wood flooring, which is a unique physical phenomenon of solid wood flooring. It can be seen that it is very important to control the moisture content of the floor.

Not only in production, but also in laying, so that the floor is not deformed by moisture.
