Abstract:

A fast clustering method was established for plastic steel window samples with unknown product information under the three indicators including product source, brand, and use purpose. The element contents of 40 plastic steel window samples with different brands, different use purposes and different sources were analyzed by X?ray fluorescence spectrometry and a handheld fluorescence spectrometer under the experimental conditions of Ag as anode target, voltage of 50 kV, current of 200 μA and acquisition time of 70 s. According to the experimental results, the index elements of Pb, Ti, Cl with species difference were selected. Through calculating the sum of standard deviation of the samples and considering the relative significant relationship among the brand, source and use purpose, the clustering results of 40 samples of plastic steel windows were obtained. This method can provide a new model for the clustering of samples collected in field investigation, indicating a certain practical significance.

Key words: plastic steel window, X-ray fluorescence spectrometry, index element, species difference, sum of standard deviation
