Asbestos, also known as "asbestos", refers to silicate mineral products with high tensile strength, high flexibility, resistance to chemical and thermal erosion, electrical insulation and spinnability.
Although asbestos is widely used, it is classified as a first-level carcinogen. Crushed asbestos fibers will form dust, which will accumulate in the lungs when inhaled by the human body and cannot be excluded. Long-term accumulation will cause disease and cancer.
At present, although the use of asbestos is not completely prohibited in our country, it is also clearly stipulated that amphibole asbestos fibers can not be found in talc powder of cosmetic grade, pharmaceutical grade and food grade by X-ray diffraction analysis.
There are many testing methods for asbestos, because of the different environments in which asbestos appears, different evaluation purposes, and different selection methods, so no test can solve all the problems. Only by combining them can the validity and accuracy of detection be guaranteed. The qualitative and quantitative analysis of asbestos was carried out by XRD, PLM, SEM, FTIR and other instruments.
X-ray diffractometer (XRD) test principle is that each mineral has its specific X-ray diffraction data and atlas, the intensity of its diffraction peak is proportional to its content, according to which to determine whether the sample contains a certain asbestos mineral and determine its content.
