镀金用柠檬酸金钾的制备方法技术

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。

Process for the preparation of potassium citrate gold for gilding

A method for preparing gold plated with gold potassium citrate, the preparation method of the product uniformity, in the transport, storage process is in the caking problem fundamentally, which is characterized in that the preparation process is as follows: to the mixing device with powdered potassium aurous cyanide and water, powder like lemon acid potassium salt, citric acid and salt water type weight ratio (0.01 ~ 0.12): 1, mixing; a mixture of 10 mesh sieve; drying the mixture after sieving the mixture; after drying over 20 mesh sieve. The optimum range of weight ratio between water and citric acid type potassium salt is (0.06 - 0.08): 1. The product has good uniformity, no segregation and no agglomeration during transportation and storage, and the loss of gold is small during the preparation process.
