湿磨助剂对铜金粉光亮度与洗涤效果的影响

Influence of Assistant on Gloss of Bronze Powder and Abstersion Efficiency in Grinding Process

研究了在铜金粉湿磨过程中所添加的表面活性剂的乳化及洗涤作用原理,测试了湿磨后洗涤污水及湿磨原液的透光率,并分析了不同表面活性剂对铜金粉湿磨后洗涤效果的影响,优选出最佳的铜金粉湿磨助剂配方。实验结果表明,采用十八胺、硬脂酸、OP-4、水复合的湿磨助剂能有效提高铜金粉湿磨后洗涤效率和铜金粉的质量;OP系列乳化剂与助磨剂十八胺复配使用时,乳化净洗作用OP-4优于OP-7和OP-10;助磨剂十八胺在铜金粉的湿磨过程中的效果优于三乙醇胺,加入硬脂酸助磨剂的助磨效果优于不加硬脂酸复合助剂的助磨效果。

The effect of surfactant on the abstersion of bronze in grinding process was studied, and different grinding assistants were tested. Many different surfactants were used in the grinding of the bronze powder and the abstersion effects of these assistants after the grind were analized in order to optimize the best formula of the grinding assistant. The results show that the washing efficiency and the quatity of the brozen powder can be improved effectively when the compound modifier composed of octadecanoic amime and stearic acid and OP-4 and water was used as the wet-grinding assistant; as for the abstersion effect, the OP-4 was better than OP-7 and OP-10 when OP series and octadecanoic amime were used; the effect of octadecanoic amine was better than that of osmotic reagent in ginding process and the grinding effect was better with stearic acid added than that without stearic acid.
