木材干燥理论在木材加工技术中的应用分析

木材干燥理论(平衡含水率、木材传热及水分扩散、干燥应力和应变等)在木材的预处理、木材干燥工艺过程、木材的保护(贮存、杀虫和防霉)、木制品的加工,以及木结构的强度设计中都有广泛的应用。干燥理论对提高木材干燥的质量、缩短干燥时间、节约能耗、防止木制品在使用中开裂和变形,以及对保证木结构的强度和安全有着重要的指导作用。

Application of wood drying theory in lumber processing

Wood drying theory,i.e.,Equilibrium Moisture Content(EMC),heat-transfer and moisture-diffusion,drying stress and strain etc.was widely applied in wood pretreatments,drying process,wood protection(storage,wood sterilization),wood-products manufacturing and strength-design of wood-structure.Wood drying theory played an important role in improving wood drying quality,reducing drying time,saving energy-consumption,preventing checks and deformations of wood-products and ensuring strength and safety of wood-structure.
