摘要
在石材检测中,准确判断石材的种类对石材的正确选用具有重要的意义。目前,选用标准主要根据石材的种类和经验来判断。当难以判断石材的种类时,人们常选用X射线衍射仪或化学分析方法进行判断。这些方法主观性较强或是有损检测。本文采用傅里叶变换红外光谱仪测量石材的红外光谱。根据特征吸收峰判断石材的种类。该方法具有方便、快捷、准确和无损检测等优势,对以后石材检测试验方法的标准制定具有参考意义。
In stone detection, the accurate identification of stone types is of great significance to the correct selection of stone. At present, the selection standard of stone is mainly based on the kinds of stone and use experience. When the kinds of stone are difficult to identify, the X-ray Diffraction （XRD） or chemical analysis method is usually used. These methods are subjective or detrimental. A Fourier Transform Infrared （FTIR） spectrometer is used to measure the infrared spectra of stone. Then, the characteristic absorption peaks in the measured infrared spectra are used to identify the types of stone. This method is convenient, fast, accurate and nondestructive. It is helpful to the setting of stone detection standards in the future.
