无水硫酸铁及球型干燥剂的制备

Preparation of Anhydrous Ironic Sulfate and Spherical Desiccating Agent

无水硫酸铁的干燥强度优于无水硫酸镁 ;干燥容量大大超过硅胶 ,是很值得开发的一种无机盐干燥剂 .由硫铁矿烧渣制备硫酸铁并将其制成球型 ,不仅降低了成本 ,而且使用方便 .

The desiccating ability of anhydrous ironic sulfate is better than that of anhydrous magnesium sulfate. Its desiccating volume is much better than that of silica gel. As a kind of inorganic salts desiccating agent, it is well worth of developing. Ironic sulfate is made from sulfur iron ore and is made spherical. The method not only reduces costs, But it can be used conveniently. The method of making particles can be applied to other inorganic salts most in use.
