氯化钾在颗粒重过磷酸钙游离酸中和调理中的应用研究

Application Study for Potassium Chloride in Neutralization Conditioning of Free Acid of TSP

通过研究化学反应原理,推导出氯化钾可用作重过磷酸钙游离酸中和调理剂的理论依据;并通过试验和工业化生产验证:氯化钾可用作重过磷酸钙游离酸中和调理剂,并能克服目前普遍使用的中和剂存在的不足,颗粒磷钾二元复合肥成品的强度、水分、总养分等各项质量指标均优于颗粒重过磷酸钙。

Through studying the principle of chemical reaction,the theoretical basis is derived that potassium chloride can be used as neutralization conditioning agent for free acid in TSP; and through test and industrial production,potassium chloride can be used as neutralization conditioning agent for free acid in TSP,and can overcome the deficiency in the neutralizing agent which is commonly used at present. The strength,moisture,total nutrient and various other quality indicators of the granular phosphorus and potassium binary compound fertilizer product are better than that of TSP.
