In the processing of solid wood mud line white embryo, drying is an extremely critical link, which directly affects the quality, stability and feasibility of subsequent processing of the product.
First of all, wood pretreatment before drying is crucial. This includes reasonable sawing and classification of wood, and distinguishing according to factors such as wood type, moisture content, and texture direction. For example, for some wood species that are easy to deform, such as pine, special attention should be paid to the control of its initial state. When sawing, try to ensure that the size of the wood is uniform and reduce uneven drying caused by irregular shapes. At the same time, it is necessary to remove the bark, rotten parts and possible impurities such as grease on the surface of the wood. These impurities will affect the evaporation rate and uniformity of water. The pretreated wood can better respond to the treatment conditions during the drying process and reduce the probability of defects.
Secondly, choosing a suitable drying method is one of the key technical points. Common drying methods are natural drying and artificial drying. Natural drying has a low cost, but a long cycle and is greatly affected by environmental factors. It is suitable for solid wood mud line white embryo processing with low drying time requirements and small quantities. Artificial drying, such as kiln drying, can precisely control parameters such as temperature, humidity and air circulation speed of the drying environment. During the kiln drying process, the temperature setting needs to be determined according to the type of wood. Generally speaking, the drying temperature of hardwood is relatively low to prevent stress cracks inside the wood. For example, the drying temperature of oak is usually controlled between 40-60℃. At the same time, the humidity adjustment should match the temperature. The humidity can be appropriately higher in the early stage, and gradually decreases as the drying process progresses to ensure that the moisture on the surface and inside of the wood can be slowly and evenly dissipated. The air circulation speed must ensure that the evaporated moisture can be taken away in time, but it should not be too fast to cause the surface of the wood to crack.
Furthermore, monitoring and adjustment during the drying process are indispensable. By setting sensors inside the wood and in the drying environment, key data such as the moisture content and temperature changes of the wood can be monitored in real time. When it is found that the moisture content of the wood drops too fast or unevenly, the drying parameters are adjusted in time. For example, if the moisture content of a part of the wood is significantly higher than that of other parts, the temperature of the area can be appropriately reduced or the air circulation can be increased to promote balanced evaporation of moisture. And it is necessary to regularly check whether the wood has signs of deformation, cracking and other defects. Once found, remedial measures should be taken immediately, such as adjusting the drying process, humidifying and softening the wood, etc., to ensure the quality stability of solid wood mud line white embryo during the drying process.
Finally, the balance treatment in the later stage of drying is equally important as the quality inspection. When the moisture content of the wood reaches the expected target, the drying cannot be ended immediately, but a period of balance treatment should be carried out to make the moisture content inside the wood more evenly distributed. After that, a comprehensive quality inspection is carried out on the solid wood mud line white embryo to check whether there are problems such as deformation, cracking, and excessive moisture content. Only products that have passed strict inspection can enter the next processing procedure, thereby providing high-quality basic materials for subsequent molding, grinding, painting and other processes, and ensuring the quality and performance of the final product of solid wood mud line white embryo.
