【摘要】：本文研究了厚度3mm和5mm的铁杉、椴木、拟赤杨三种木质装饰薄板的干燥特性和干燥工艺,筛选出了较优的干燥基准。试验结果表明:薄板的变形与温度、薄板的终含水率和薄板尺寸有关。同等情况下,温度越高,薄板变形越大;薄板的终含水率越低,其变形程度越大;薄板的厚度越小越易发生变形,薄板的宽度越大,其变形程度越大,长度对变形的影响不是很大;加压可明显减小总变形值,通过薄板局部加压和喷蒸联合处理可有效控制装饰薄板的干燥质量。
[Abstract]:In this paper, the drying characteristics and drying process of 3 mm and 5 mm thick hemlock, Linden and aldenia wood decorative sheets were studied, and the better drying datum was selected. The results showed that the deformation and temperature of the thin plates were different from each other. The final moisture content of the thin plate is related to the size of the thin plate. At the same time, the higher the temperature, the greater the deformation of the thin plate; the lower the final moisture content of the thin plate, the greater the degree of deformation; the smaller the thickness of the thin plate, the easier it is to deform, and the larger the width of the thin plate is. The greater the degree of deformation, the less the influence of length on the deformation, and the less the total deformation value can be reduced by compression, and the drying quality of decorative thin plate can be effectively controlled by the combination of local pressure and jet steam treatment.
