摘　　要：采用偏光显微镜法测定涂料及其原材料中的石棉。讨论了将石棉的形貌、延性和色散染色等特征作为主要依据,颜色、消光角、多色性等特征作为辅助依据来鉴定石棉种类中的各种问题,并用X射线衍射法验证了试验结果的准确性。研究了易与石棉混淆的纤维种类及其鉴别方法,对石棉检测过程中的注意事项进行了说明。The asbestos in coatings and its raw materials was identified The problems in identifying the type of asbestos were discussed through spersion stain subsidiary basining Th by using the polarized light microscopy. the morphology, ductility and chromatic of asbestos as main basis and through the color, extinction angle and polychroism etc. as e accuracy of test results was verified by the X-ray diffraction. The types of fibers which were easy to confuse with the asbestos and their identification method were studied. The matters needing attention during the asbestos detection were also mentioned.
