    辨别旧木方腐烂与虫蛀的方法

            2026-10-31 10:35:00        194次浏览

    挑选或者回收旧建筑木方时,快速识别腐烂、虫蛀木料,能避免经济损失和隐患。腐烂木料表层颜色发暗发黑,用手按压发软,敲击声音沉闷空洞,掰开之后内部呈粉末状、海绵状,这类木料力学强度基本丧失,不能用于受力支撑。虫蛀木料表面有细小虫眼,伴随木粉掉落,顺着虫眼往里查看,如果通道贯穿木料,承重能力大幅下降。区分自然干纹和腐朽裂纹,正常干裂纹路边界清晰,质地坚硬;腐朽裂纹周边松软发黑,二者很容易混淆。

    受潮初期的木料只是表层发潮,及时通风晾干之后还可以正常使用;已经深度霉变腐烂的木料,没有修复价值,只能按粉碎废料计价。大批量收货时随机抽样,截断木料查看芯材状态,防止表面看着完好,内部已经腐坏的料子混入好料之中。
