竹重组材的X射线光电子能谱分析
X-ray photoelectron spectroscopy analysis of reconstituted bamboo lumber
摘要
Abstract
Reconstituted bamboo lumber was prepared by cold-pressing or hot-pressing process. Surface element composition of different samples was compared by means of X-ray photoelectron spectroscopy ( XPS) . The results showed a remarkable difference between element C and O of hot-pressed and cold-pressed reconstituted bamboo lumber with respect to both linkage type and relative content. Compared to hot-pressed reconstituted bamboo lumber, cold-pressed lumber showed a significant increase of CA ( -C -C or -C -H ) content and decrease of CB ( C -0 or C -OH ) content. Lower content of Cc ( C = 0 ) was also found on the surface of cold-pressed lumber, while the content of CD(O-C=O) kept almost unchanged. It can be concluded that chemical components, such as cellulose, hemicelluloses, lignin and extractives were more or less influenced by pressing method, which, in turn, could influence physical and mechanical performances of reconstituted bamboo lumber.关键词
