不溶性硫磺的合成方法、应用及市场

The Synthetic Method,Application and Market of the Insoluble Sulfur

生产不溶性硫磺是提高普通硫磺附加值的一种有效手段,本文简要介绍了不溶性硫磺的形成机理、合成方法、应用及市场情况。气化法、低温熔融法、接触法、辐射法是不溶性硫磺的主要合成方法,其中汽化法是目前国内外工业上较为成熟的方法;不溶性硫磺主要用于子午线轮胎的生产,也可用于电缆、胶辊、油封、胶鞋等橡胶制品;随着子午线轮胎需求量的日益增长,不溶性硫黄的市场前景广阔,且高含量、高温稳定性、高分散性、低静电是不溶性硫磺产品未来的发展方向。

The production of insoluble sulfur is a kind of effective means of enhancing the added value of the common sulfur, this paper briefly introduces the formation mechanism, synthesis, application and market situation of insoluble sulfur.Gasification method, low temperature melting method, contact method, radiation method are the main synthesis methods of insoluble sulfur, of which the evaporation method is the relatively mature one in industry at home and abroad.Insoluble sulfur is mainly used for the production of radial tire, and it can also be used for producing cable, rubber roller, oil seal, rubber shoes and other rubber products. As the demand of radial tires increasing, insoluble sulfur＇s market prospect is broad, and high content, high temperature stability, high dispersity and low static electricity is the developing direction of insoluble sulfur product in the future.
