1序言.众所周知,在硫化过程中由于硫化橡胶的各种物理特性和游离硫的含量是持续变化的,所以游离硫的含量与硫化橡胶的初期物理特性有着很密切的关系。也就是说,游离硫含量的测定在制品的品质管理上起着重要的作用。并且游离硫的
1 Introduction It is a well-known fact that the content of free sulfur is closely related to the initial physical properties of the vulcanizates because of the varying physical properties and free sulfur content of the vulcanized rubber during vulcanization. In other words, the determination of free sulfur content plays an important role in the quality control of the product. And free sulfur
