摘要:
以毛竹(Phyllostachys heterocycla cv. pubescens)碾压疏解竹束为原料,对其进行120、140、160℃各60 min,160℃各30、60、90 min的高温热水处理并压制成竹重组材,运用紫外老化试验箱加速老化方法对老化前后的竹重组材进行颜色变化分析,并运用扫描电子显微镜观察高温热水处理工艺前后的竹重组材表面形貌。结果表明:竹重组材颜色稳定性随着高温热水处理温度的升高而提升,160℃下ΔE*ab(处理前后颜色变化的大小)值最小为9.1,而处理时间对颜色稳定性的影响并不显著;扫描电镜结果表明,经过高温热水处理后的竹重组材相比未经处理的竹重组材的表面破坏程度大,表面组织也变得更加的松散,而未处理的竹重组材表面要相对致密。
Abstract:
Bamboo bundles were hot water treated at 120, 140, 160℃ with duration of 60 minutes, and at 160℃ with duration of 30, 60 and 90 minutes, and then treated bundles were pressed to reconstituted bamboo lumber(RBL). Color fastness of RBL was tested by climate chamber, and surface of RBL was observed by SEM. The results showed that the color fastness of RBL increased with temperature, the minimum color difference under 160℃ was 9.1, and treatment duration had no evident effect on color fastness. SEM demonstrated that surface of treated RBL was damaged compared with no treatment.
