Abstract：Aming at the problem of complex test method and long test period on testing acidity coefficient of rock wool prod-ucts applied in architecture external thermal insulation,X-rays fluorescent(XRF)spectrometry was established to test the acidity coefficient. Through microanalysis on rock wool products by scanning electron microscope(SEM)and X-rays diffractometer(XRD), the necessity of using glass fuse piece method instead of pressed pellet to prepare specimen. Compared chemical analytical method with X-rays fluorescent spectrometry,the result showed that XRF has advantages of simplicity of operator and speediness,and the accuracy and precision meet the requirements of national standards.
