With the increasing quality of life, people choose to home improvement materials is better. Ground decorative materials, wood flooring with its green, grace and elegance, comfortable characteristics become everyone's first choice. Experts suggest that consumers in the choice of solid wood flooring, solid wood flooring in addition to focusing on species, color, finish and service, but also can not ignore a key indicator that the moisture content. Affect the stability of the core elements of solid wood floor - the moisture content of the various regions of the humidity and temperature are different,Eco friendly garden decking but in different seasons are relatively stable. Solid wood flooring for a long time in this relatively stable temperature and humidity, the wood in the water will reach a relatively constant value, then the timber most stable performance, the value of this constant is called the equilibrium moisture content of wood flooring.
Equilibrium moisture content of solid wood flooring should correspond to the average local temperature and humidity, high moisture content in the wood floor if the indoor environment, not only the damp floor itself affect human health, but also lead to diffusion of moisture to the indoor floor patchwork increases, even produce floor cracking or film cracking phenomenon. If the moisture content is less than solid wood flooring use environment, indoor floor will absorb moisture, Cheap and durable Porch floor resulting in solid wood flooring moisture expansion bagging appears monolithic floor or tile, or even a large floor surface area arched. Thus, controlling the moisture content of wood flooring is good, you can maximize the life of solid wood flooring. Solid wood flooring moisture content presentation
Wood moisture contained in three forms, one is present in the cell chamber and the water in the intercellular spaces, is present in the capillary water, called free water. The second cell wall is absorbed by the water, called adsorbed water. The third is a tissue composed of water, called chemical water.
When wet wood moisture evaporation, the first free water is lost, when the free water has evaporated and the adsorbed water is still in the water content when saturated, it called the fiber saturation point moisture content. Performance wood fiber saturation point is a turning point, above the fiber saturation point, strength of the timber is constant, does not change with moisture content varies. While wood does not shrink and expansion of such changes on the volume. When the moisture content falls below the fiber saturation point,Long life span balcony raliing which is when the cell walls of adsorbed water began to evaporate moisture content decreased with the intensity increased, shrinkage and swelling phenomenon clearly presented. Different wood fiber saturation point moisture content between about 22% to 33%. Various areas of relatively stable humidity and temperature in different seasons both nature. Wood is located in the relatively long time temperature and humidity environment, the water content will reach will reach a relatively constant.
At this moisture content is called the equilibrium moisture content.Equilibrium moisture content of wood with changes in their environment in which temperature and humidity changes, when the equilibrium moisture content and ambient humidity difference, will tend to be close to the environment. This produces wood swelling and shrinkage phenomenon,High-performance composite decking which is a physical phenomenon unique to wood. Wood is an anisotropic body. Actual use of the timber in which the moisture content below fiber saturation point, so moisture gains and losses are mainly the cell wall of the adsorbed water. The vast majority of cell timber longitudinal growth, its expansion and contraction are perpendicular to the direction of the cell wall. As a floor, we can find it generally no longitudinal expansion and contraction and expansion in the width direction shrinkage is generally 3% to 6%. Thus, good control of the moisture content of the floor is very important. Not only must pay attention to the production, laying more attention should be paid, not damp floor deformation
