摘要本文概述了氧化亚铜(Cu2O)的应用及超细氧化亚铜的特性、制备工艺进展；研究以企业现有产品氯化亚铜为原材料，采用水解沉淀法制备氧化亚铜粉体小试工艺。工艺包括：用氯化钠将不溶性氯化亚铜转化成可溶性络合物，该络合物在加热条件下与磷酸钠反应，生成氢氧化亚铜，氢氧化亚铜进而脱水，制得氧化亚铜。通过氯化钠与氯化亚铜形成络合物的方法，使氯化亚铜溶解，同时能使一价铜得到缓慢释放，利用磷酸钠进行水解，提供碱性环境，使得氢氧根负离子得到缓慢地释放，确保氢氧化亚铜晶粒的均匀生成。依据小试工艺和相关参数，在物料衡算、热量衡算基础上进行了车间布置，最后再进行工艺流程图、车间布置图的设计与绘制。为生产企业提供工艺流程与技术贮备。62247

Hydrolysis of cuprous oxide prepared by the preparation technology and the production design Abstract

This design paper explain Outlines the application of the cuprous oxide (Cu2O)and characteristics and technological progress of superfine cuprous oxide;Study to the enterprise existing product cuprous chloride as raw materials, preparation of cuprous oxide is obtained through hydrolysis precipitation test in powder technology, using sodium cuprous chloride into complex, complex by heating, in turn, react with sodium phosphate, cuprous oxide products for hydrogen, hydrogen cuprous oxide, in turn, dehydration, with cuprous oxide. With cuprous chloride by sodium chloride to form complex method, the cuprous chloride dissolved, monovalent copper can get slow release at the same time, using sodium phosphate hydrolysis, to provide an alkaline environment, let hydroxide ions get released slowly, ensure copper hydroxide crystals generated uniformly. According to the test process and related parameters, and then on the basis of material balance, heat balance, make plant layout, finally, design the process flow diagram and plant layout. Provide process and technical reserves for the production of enterprises.
