Description
Technical Field
The utility model relates to a timber health preserving technical field, concretely relates to timber health preserving room.
Background
Because wood has hygroscopicity, can absorb or release moisture because of the humiture change of the air in the environment, can produce the wet swelling phenomenon of drying shrinkage when the environmental humidity is too low or too high. The dry shrinkage and wet expansion of the wood mainly depend on two indexes of the water content and the equilibrium water content. Moisture content of wood: the water content of the wood is determined, namely the mass of the water in the wood accounts for the absolute dry mass of the wood. And (3) balancing water content: because the wood has the characteristics of moisture absorption and desorption, when the temperature and the humidity of the environment change, the wood can correspondingly absorb water from the environment or release water to the environment, so that a new water balance state is achieved with the environment, namely the finally achieved moisture absorption stable water content or the analysis stable water content is called as the balance water content.
The purpose of wood curing mainly comprises two parts of moisture regulation and stress release. The method is mainly applied to the fields of floors, furniture, wooden doors and the like. The wood health preserving house has the following functions: adjusting the moisture of each part of the solid wood composite material before pressing and releasing the stress of the blank after pressing. Carrying out health preserving treatment on the dried wood to promote the water content to be more uniform; preventing moisture absorption and moisture regain of the dried wood; the moisture content gradient of the wood is reduced, and the residual stress in the drying process of the wood is eliminated. The hidden quality trouble is reduced, and the quality of the product is more effectively ensured.
In a relatively closed space (such as a curing room), the moisture contained in the air is relatively stable. When the temperature of the air rises, the moisture content in the air increases, so when the moisture content in the air is constant, the temperature of the air increases, the relative humidity of the air decreases, and the corresponding equilibrium moisture content of the wood decreases. The equilibrium moisture content of the curing room is set through the temperature and the humidity, so that the moisture content of the wood in the curing room is promoted to be close to the set equilibrium moisture content value after a period of time.
In actual production (especially in southern China), the moisture content of finished products, semi-finished products and raw materials required by people is generally lower than the equilibrium moisture content of wood corresponding to air in the external environment. Therefore, by the principle, the air in the curing room is heated to a certain degree, so that the corresponding wood equilibrium moisture content value is in the range required by people, and the moisture content of finished products, semi-finished products and raw materials in the equilibrium room is not increased due to the absorption of moisture in the outside air.
The water content of the dried wood is uneven, the residual stress can influence the use quality of the product, if the plate with the too low water content is directly made into a finished product, the plate deforms due to wet expansion in the use process, the water content is too high, and the problems of gaps, cracking and the like are easily caused after the plate is used. The excessive internal stress can cause the problems of product deformation, cracking and the like.
Through health preservation, the moisture content of the wood is further balanced, the moisture content of the wood is ensured to be within a required range, and the internal stress is released, so that the blank reaches a relatively stable state.
