便携式X射线荧光光谱仪在西藏寺庙木材防腐透入度检测中的应用

木材防腐处理是一项专业性很强的工作,在西藏偏远地区缺乏专业设备的条件下要保证处理效果,需特殊的处理工艺与高效的检测手段。透入度和载药量是衡量木材防腐处理效果的两个重要指标:载药量可通过换算得出结果；透入度一般需要在实验室使用仪器检测。便携式X射线荧光光谱仪的发明使得以前需要在实验室开展的工作可在现场完成,该仪器通过检测木材中防腐剂所含的金属元素确定透入度,具有检测速度快、操作简单的特点。研究结果可为西藏偏远地区寺庙木材防腐防虫处理工程质量控制提供借鉴。

Application of pXRF in the detection of wood penetration for Tibetan temples

Wood preservation is a highly professional job. Due to the lack of professional equipment in remote areas of Tibet, special treatment technologies and efficient detection measures are needed to ensure the effects. Penetration and retention are two important parameters used to evaluate the preservative effects:retention can be acquired via calculation; penetration generally needs to be tested using instruments in the lab. The invention of the portable X-ray fluorescence (pXRF) spectrometer enables work which used to be carried out in the laboratory to be completed on site. The instrument determines the penetration by detecting metal elements contained in a preservative; this method features fast detection and simple operation. This study could provide a reference for the quality control of wood anti-corrosion and insect-proof projects for Tibetan temples in remote areas.
