Freshly harvested or cut wood is just raw and dried wood only becomes valuable structural materials. The wood must be dried to a so-called equilibrium moisture content corresponding carolina container to its operating conditions, characterized by the air parameters (temperature and relative humidity). carolina container Thus dried timber may be different moisture content, which depends carolina container on the use of wood: furniture manufacturing wood is dried to 7-8%, construction products - up to 18 - 20% and so on dried timber is a valuable building material, only to be properly treated in the applications.
Tumble dried wood acquires a smoother surface, so do not drink like a sponge "of air humidity carolina container (as it happens naturally dried wood, which has a porous surface). Dried wood is much more stable, because even the air temperature and humidity can only slightly change the dimensions, while buying a green-dried timber can only guess about its dimensions after dry. Another flaw of the green wood is wet environment that breed mold and wood-depleting mushrooms, which requires only the temperature from -50C to + 500 C and humidity greater than 22 - 23%. (Undried wood moisture carolina container content of about 30% and more). Therefore, dried wood has a high resistance to mold. In order to strengthen the aseptic quality dried wood is impregnated by an additional (green wood can not have a drink enough antiseptic).
However, dried wood and may have defects. One of them, the cracking, which is most often seen on massive beams, pillars, and other types of beams. During the drying of wood, primarily moisture evaporates from the outer layers and only later from the deeper inner layers. The outer layers carolina container of wood begins to shrink, the inner, the higher humidity, resists shrink. The existence of different individual layers of wood volume carolina container change internal stress exceeds the tensile strength, the wood will crack. Yet wood construction purposes is not a big flaw, it is important that dried timber can withstand twice the load compared to the wet. Another minus arising drėgstant or the drying of wood is its casting, such as when. cleats become bow-shaped board is concave and so on. These defects are particularly likely to occur when the wood runs a sudden change in air (usually when dried naturally). Tumble-dried wood has a lot less these defects as it applies to a special drying mode (adjustable air temperature and humidity) and the weights are placed to prevent internal mechanical stresses deform wood products.
Even dried wood a little carolina container "walking", so you should avoid the use of wood in rooms where temperature and humidity conditions are unstable. If this is not possible, the calculations necessary to determine the required clearance. Properly dried timber carolina container must be covered with protective paint or varnish slowing down its mouth-swelling. Massive dried wood (beams, columns, and so on. S) must comply with the room temperature and moisture regime, they must be used to dry the wood overhead: internal wet areas -12-15 per cent., Internal dry rooms 8-10 percent. Outdoors, protected carolina container from precipitation structures - about 15 per cent., With non-protected - 20 percent.
