优等品硫磺

Sulphur at a premium

对于在储运过程中遇到的某些现实情况,广泛采用的“优等品”硫磺标准并非总是适用的。提出对加拿大硫磺开发研究所1977年公布的《成型固体硫磺优等品质量标准》中的一些指标进行修订。建议在加入SLS之前硫磺的水分质量分数为0．8％-1．8％,硫化氢质量分数小于0．003％。

The widely accepted definition of ＂premium＂ sulphur does not always allow for real conditions encountered during handing and storage. Some change is needed for ＂premium product＂ standard prepared by SUDIC in 1977. It is suggested to set moisture content of formed sulphur before SLS application at 0. 8 wt% （minimum） - 1.8 wt% （maximum） and hydrogen sulphide not more than O. 003 wt%.
