| 中文摘要: |
| 研究不溶性硫黄粒度分布的测试方法。结果表明：激光衍射法干法测试无法得到真实的粒度分布，采用激光衍射法湿法测试，以无水乙醇为分散剂，结合纯搅拌处理工艺，测试结果更符合实际情况；该方法测定的粒度分布结果重复性好，且与扫描电子显微镜照片相符合，说明了该方法的可靠性。 |
| 英文摘要: |
| A test method for the particle size distribution of insoluble sulfur was studied.The results showed that the laser diffraction dry test could not obtain the true particle size distribution.The laser diffraction wet test，which using absolute ethanol as the dispersant，and the agitation treatment process，the test results were more in line with the actual situation.The particle size distribution results were reproducible and consistent with the scanning electron micrographs，indicating the reliability of the method. |
