摘　　要：有机盐结块问题严重影响有机盐产品工业化的应用及推广。研究表明,有机盐组成、温度、湿度、压力和颗粒粒径等均是造成有机盐结块的因素,其中湿度和压力是2个重要的影响因数。因此密封隔湿、减轻压力、控制粒径、保温等均是防结块的有效技术手段。通过工业甲酸钾结块实验研究,AK-3防结块剂加量为0.3%时,有机盐样品破碎压力为3.2 kg,压实的样品比较松软,可压碎至粉末,接近原状。有机盐防结块技术现场试验表明,AK-3防结块剂在0.3%的添加量时具有良好的防结块效果,可完全达到现场要求。Caking plays an important negative role in the application of organic salts. Studies show that factors such as composition, temperature, humidity, pressure and particle size all contribute to the caking of organic salt. Of these factors humidity and pressure are the most important ones, thus anticaking can be achieved by sealing and humidity control, minimizing pressure, controlling particle sizes, and maintaining storage temperature etc. The effect of an anticaking additive, AK-3, was tested on potassium formate, showing that the breakdown pressure of the potassium formate is 3.2 kg at AK-3 concentration of 0.3%, and the pressurized salt sample is fluffy, and can be pulverized almost to its original state. This test shows that AK-3 can be used in field application to prevent organic salt from caking.
