<p>best teak vinyl fencing reviews equilibrium moisture content is an important aspect of quality wood flooring decision, so understanding the knowledge of the equilibrium moisture content of wood to understand what impact it will have on the quality of the wood flooring, is necessary. First of all, need to know what the equilibrium moisture content of wood flooring? After the trees were cut down to make wood floors, although there is no oxygen function, there regulate indoor air humidity and temperature characteristics. Wood in order to seek its own equilibrium moisture content will be changes in the ambient air moisture and absorb or release moisture. Wooden floor moisture content due to the characteristics of different species itself, in which different geographical locations, but not the same. In the case of species characteristics can not be changed and reasonable health (adjust properties such as moisture content of the wood floor of a process), so that the moisture content of the wood flooring is consistent with the local average moisture content, has become the moisture content of wood to ensure the key to stability .</p>
<p>Long-term exposure to certain wood humidity and relative humidity in the air will eventually reach a relatively constant moisture content, this time wet wood moisture reconciliation equal speed, when the proportion of the water content of the high density polystyrene lumber is called the equilibrium moisture content. This stable moisture status, depending on the relative humidity of the ambient air, and the temperature and the degree of wet and dry wood, it will change with atmospheric conditions and increase or decrease, depending on the season produce subtle changes. In accordance with state regulations, the moisture content of wood flooring 5% -14% qualified.</p>
<p>Secondly, the need to understand what factors could affect the equilibrium moisture content of wood flooring? In fact, the material is not the same in different species, different ability to absorb or release moisture, coupled in the factory health cycle are not the same, resulting in different brands, different species of wood swell and shrink is not the same degree. Wood floor believes that several factors ability to absorb or release moisture, wood floor, health cycle affect wood swell and shrink levels, in a sense can be attributed to the moisture content of the wood floor problems. As we all know, the moisture content of the wood fiber saturation point will be shrinkage phenomenon occurs when swelling (30%) range, thus changing the size of the timber, causing the deformation of wood, defects of wood and wood products. Equilibrium moisture content of wood, not only with the use of ambient air temperature, humidity related, and because the wood species, construction, specific gravity, extract content, chemical composition, physical properties, mechanical stress, drying time and change. Finally, to understand what impact the equilibrium moisture content of wood flooring quality?</p>
<p>The moisture content of wood flooring 5% -14% of qualified, strengthen the moisture content of the wood floor is also 6% -10% of qualified, solid wood flooring moisture content of 8% to 13% as acceptable. Parquet moisture content is too high or too low will affect the adhesive strength, may cause peeling. Laminate flooring moisture content is too high or too low affect its surface decorative layer (aluminum oxide) adhesive strength, may cause skin peeling. Solid wood flooring moisture content is too high, after renovation by drying climate, moisture in the wood floor dries, shrinkage, will be in a block of wood between the emergence of a crack. The moisture content is too low, stretching the gap left when the renovation was not enough, wet, damp solid pine fence planks lincolnshire will camber, warping sound. In addition, the equilibrium moisture content of the wood floor paint film adhesion and Jiaogan have a small impact.</p>
