概述卤水提取工艺、曼海姆工艺、复分解工艺制取的硫酸钾的特点,并通过实验考察不同工艺硫酸钾对高塔硝硫基复合肥料质量的影响。结果表明,各种工艺的硫酸钾的物理指标和化学指标存在着区别,对高塔硝硫基复合肥料的部分理化指标会造成一定的影响。高塔硝硫基复合肥料需要根据不同类型配方的要求,选用不同工艺的硫酸钾,合理利用不同工艺硫酸钾的优点,生产出优质的高塔硝硫基复合肥料。
The characteristics of potassium sulfate obtained from brine extraction process, Mannheim process and metathesis process are summarized. The effects of different processes of potassium sulfate on the quality of high-pit nitro-sulfur compound fertilizer are investigated experimentally. The results show that there are differences between the physical and chemical indexes of potassium sulphate in various processes, and some of the physical and chemical indexes of high-concentration nitro-sulfur compound fertilizers will be affected to some extent. According to the requirements of different types of formula, tower nitro-sulfur compound fertilizer needs different process of potassium sulfate, reasonably using the advantages of different process potassium sulfate to produce high-quality high-tower nitro-sulfur compound fertilizer.
