摘  要:
采用炉气间接干燥窑干燥小径橡胶木,分析小径材干燥缺陷,制定干燥基准,优化干燥工艺。结果表明:橡胶木小径材在干燥过程中容易产生开裂和变形,生产中采用中温低湿工艺,可减少橡胶木小径材干燥过程中的髓心开裂和弯曲变形,干燥时间为120 h,可降低干燥成本,提高干燥质量。

摘  要:
23 mm thickness small diameter rubber-wood drying technology was researched.The results showed that small rubber wood is easy to split and warp during drying.The newly developed drying schedule improved drying efficiency and increasing board quality,that total drying time was 120 hours from initial moisture content 93% to final moisture content 8%~10%,quality of the dried lumber was good,little check,residual stresses and even final moisture content.
