镀金用柠檬酸金钾的制备方法
摘要：
一种镀金用柠檬酸金钾的制备方法，从根本上解决现有制备方法所得产品均匀度差、在运输、保存过程中易偏板结块的问题，其技术要点是：制备过程为：向混合设备中加入粉末状氰化亚金钾、水、粉末状柠檬酸酸式钾盐，水与柠檬酸酸式钾盐的重量比为(0.01～0.12)∶1，混合均匀；混合物过10目筛；对过筛后的混合物进行烘干；烘干后的混合物过20目筛。水与柠檬酸酸式钾盐的重量比的最佳范围为(0.06～0.08)∶1。其所得产品均匀度好，在运输，保存过程中不偏析，不结块，而且制备过程中黄金损耗量小。
摘要（英）：

The invention discloses a preparation method of potassium gold citrate for gold plating, which basically solves the problems that the product prepared by the existing preparation method has poor uniformity and is easy to segregate and agglomerate in the processes of transportation and preservation. The preparation method is technically characterized by comprising the following preparation processes of: adding powdered potassium gold cyanide, water and powdered acidic potassium citrate into mixing equipment and uniformly mixing, wherein the weight ratio of the water to the acidic potassium citrate is (0.01-0.12):1; sieving the mixture with a 10-mesh sieve; drying the sieved mixture; and sieving the dried mixture with a 20-mesh sieve. The optimal weight ratio of the water to the acidic potassium citrate is (0.06-0.08):1. The product prepared by the preparation method disclosed by the invention has good uniformity and can not segregate and agglomerate in the processes of transportation and preservation, and the gold loss is small in the process of preparation.
