The determinants of wood quality of solid wood furniture

by:Jinlon Furniture     2022-02-22
Solid wood furniture refers to pure solid wood furniture, which means that all materials are natural materials that have not been reprocessed and do not use any wood-based panels. Because there are no two exactly the same tree, two pieces of exactly the same material, each product will have its unique characteristics, the natural characteristics of wood, such as mineral threads, color and texture changes, needle knots, resin capsules and other natural marks , All make the furniture more natural beauty. At the same time, the quality of wood is also an important factor in determining the quality of solid wood furniture. So what factors will affect the quality of wood? 1. External factors 1. Temperature Temperature is the main factor that affects the drying speed of wood. As the temperature rises, the water pressure in the wood increases, and the viscosity of the liquid free water decreases, which is conducive to promoting the flow and diffusion of water in the wood; the moisture solubility of the copper wire drying medium is improved, and the evaporation of water on the wood surface is accelerated. But it is worth noting that if the temperature is too high, it will cause cracking and deformation of the wood, reduce the mechanical strength, discoloration, etc., which should be properly controlled. 2. Humidity Relative humidity is an important factor affecting wood drying speed. When the temperature is the same as the air flow rate, the higher the relative humidity, the greater the partial pressure of water vapor in the medium, and the more difficult it is for the moisture on the surface of the wood to evaporate into the medium, and the slower the drying speed; when the relative humidity is low, the surface moisture evaporates quickly. The moisture content of the surface layer decreases, the moisture content gradient increases, the moisture diffusion increases, and the drying speed is fast. However, if the relative humidity is too low, it will cause the occurrence or even aggravation of drying defects such as cracking and honeycomb. 3. Air circulation speed Air circulation speed is another factor that affects wood drying speed. High-speed airflow can destroy the saturated steam boundary layer on the surface of the wood, thereby improving the heat and mass transfer conditions between the medium and the wood, and speeding up the drying speed. For difficult-to-dry wood or when the moisture content of the wood is low, the internal moisture movement of the wood determines the drying speed; increasing the flow rate of the large medium to accelerate the evaporation of surface moisture is of no practical significance, but will increase the moisture content gradient and increase the drying rate. The danger of defects. Therefore, difficult-to-dry materials do not require a large medium circulation speed. Related reading: Which kind of wood is good to buy solid wood furniture? 2. Intrinsic factors 1. Wood species and structural characteristics. Different tree species have different structures. The size and number of pores and the size of the micropores on the pore membrane are very different. Therefore, the moisture moves along the above path. The degree of difficulty is different, that is, the wood species is the main internal factor that affects the drying speed. Because ring-hole hard broad-leaved trees (such as rosewood) have more fillings in conduits and pits, and the diameter of the micropores on the pit membrane is small, the drying speed is significantly lower than that of diffuse-porous broad-leaved trees; in the same tree species, the density increases , The water flow resistance in the large capillary tube increases, and the water diffusion path in the cell wall is extended, making it difficult to dry. 2. Wood thickness The conventional drying process of wood can be roughly regarded as a one-dimensional heat and mass transfer process along the thickness of the wood. As the thickness increases, the heat and mass transfer distance becomes longer, the resistance increases, and the drying speed decreases significantly. 3. Wood moisture content below the fiber saturation point, as the moisture content decreases, the lateral diffusion coefficient of absorbed water decreases, while the diffusion coefficient of water vapor in the cell cavity increases, because water vapor in the cell cavity during the drying process The proportion of medium diffusion is not large, the lower the water content, the longer the water diffusion path, so the lower the water content, the more difficult it is to dry. 4. Wood heartwood and sapwood There are more inclusions in the heartwood cells of broad-leaved trees, and most of the pores in the heartwood of conifers are occluded, so the heartwood is more difficult to dry than the sapwood. 5. Wood grain direction wood ray is conducive to water conduction, and the water conduction along the radial direction of the wood is about 15%-20% larger than that along the chord direction. Therefore, the drying speed of string cutting board is usually faster than that of radial cutting board.
