| 中文摘要: |
| 介绍不溶性硫黄（IS）的生产技术现状。溶剂连续法工艺具有成本低、热稳定性好、环保压力小等优势，但对系统自动化水平要求较高，工艺控制相对严格。国内IS企业多采用溶剂间歇法、高温水法和熔融水法。高热稳定性、高分散性和高含量是IS发展的目标。 |
| 英文摘要: |
| The current status of production technology of insoluble sulfur (IS) is introduced. The continuous process by using solvent possesses the advantages such as low cost， good thermal stability of the product and less
environmental pressure， but it requires a higher level of automation and process control. Most domestic companies use batch process with solvent， high temperature process or melt process with water. The future trend is to develop the IS with higher thermal stability， higher dispersibility and higher insoluble sulfur content. |
