As we all know you want to know how the floor, was to look at the moisture, wood flooring, for example, the moisture content of wood flooring installation areas should be selected and balanced living possibilities, such problems arise in the future use will be greatly reduced. National standards for wood flooring moisture content of 8% to 13% in the first test exhibition selected parquet moisture purchase, then test the unopened package of the same wood species, with the specifications of the moisture content of wood flooring, If the difference in the + 2% can be considered acceptable.
Performance wood fiber saturation point is a turning point, above the fiber saturation point, the intensity parquet moisture content is constant, it does not vary with the moisture content of wood flooring varies. Meanwhile parquet shrink nor swell the volume on this change. When the moisture content under parquet fell fiber saturation point, which is when the cell walls of adsorbed water begins to evaporate, strength decreased with increasing moisture content, shrinkage and swelling phenomena obviously presented. different moisture content moisture content of wood fiber saturation point between about 22% to 33%.
All regions relatively stable humidity and temperature in different seasons have nature. Parquet moisture content is located in such a relatively long period of temperature and humidity environment, the moisture content will reach a relatively constant moisture content of parquet equilibrium moisture content with the changes in their environment in which the temperature and humidity changes, When the equilibrium moisture content and humidity there is a difference, it will tend to be close to the environment. Parquet moisture content is an anisotropic body, the actual use of the parquet in the moisture content below fiber saturation point, so moisture gains and losses are mainly the cell wall of the adsorbed water. Cell majority of moisture content is longitudinal growth of its expansion and contraction, and cell walls are perpendicular to the direction.
