海门口遗址饱水古木酚醛树脂加固机理分析

在酚醛树脂加固古木效果评价的基础上，采用扫描电子显微镜和荧光显微镜对微观构造进行解析，结合X射线衍射和傅里叶变换红外光谱对酚醛树脂加固古木的加固机理进行分析。结果表明：浸入古木内的酚醛树脂绝大部分沉积在了细胞壁内，极少量以块状形式沉积在了细胞腔内；加固后古木自身纤维素结晶度有所提高；虽然侵入的酚醛树脂发生了一定程度的固化，但仍未形成大量的三维体型丙阶酚醛树脂。

Study on Reinforcing Haimenkou Sites Water Archeological Wood with Phenolic Resin Analysis on Reinforcing Mechanism

Analyzing the microstructure of reinforceming ancient wood with scanning electron microscope and fluorescence microscopy. Analyzing the mechanism of Haimenkou sites water archeological wood combining the X-ray diffraction and fourier transform infrared spectroscopy. The results show that phenolic resin has been filled in the archeological wood cell walls mainly, very few of the phenolic resin be filled in the cell cavity. The cellulose crystallinity of reinforcing archeological wood has improved. The phenolic resin immersed in the archeological wood has solidifed a certain degree, but which still didn't form a large number of three-dimensional body-type phenolic resin.
