difficult to meet the requirements

some up to 25%, the national standard provides ground water Rate below 20% can be installed on the floor, a lot of buildings that year to pay the decoration, the ground moisture content is difficult to meet the requirements. Even if the ground moisture content of 20% or less, but also ran out a lot of water. 2 wood keel of water At present, in many parts of China's wood keel is not used to dry, most rely on natural drying, individual moisture content of more than 20%, the northeast of the wood keel is almost dry, wood keel in the water Can also lead to increased water floor, resulting in tile deformation. 3 air moisture in southern China's humid air to the rainy season, the maximum relative humidity of up to 95% or more, the equilibrium moisture content of the air up to 18%, even in China's northeast and north China, 6 to 9 months During the rainy season, the moisture content of the air can reach more than 15%. If the water content of the floor is lower than the local moisture content, the floor can still absorb water. If the old building, the environment is not wet, the wooden keel and after drying, the floor (or floor) is not dry, the floor is not moistureproof. Of the water content and the environment and the equilibrium moisture content is similar to the floor does not appear tile deformation. In any case, this installation method on the ground moisture, keel in the water and moisture in the air did not prevent the role, when any moisture content than the floor, the floor will produce tile deformation, this method is extremely safe. But also does not meet the GB / T 20238-2006 wood flooring pavement, [url=http://compositeexteriorfloor.com/waterproof-floor/4125.html]flooring material for exterior[/url] [url=http://compositeexteriorfloor.com/waterproof-floor/1457.html]wooden composite chair[/url] [url=http://compositeexteriorfloor.com/hollow-floor/5351.html]fir porch flooring tongue and groove[/url]
