Ultrafine Powder of Basic Copper Carbonate：Preparation And Production Design

Abstract: Basic Copper Carbonate (Cu (OH)2 - CuCO3) is an important chemical raw material, widely used in inorganic, organic, electroplating industry, agriculture and catalysis. After superfine cupric subcarbonate due to size effect, surface effect, thus making it not only in the use of the direct has good physical and chemical and surface / interfacial properties and also for preparing superfine powder of copper oxide precursor, of downstream products with excellent physical and chemical properties. The design of the study to the company's existing product cuprous chloride as raw material by hydrolysis method preparing microspheres basic copper carbonate scale craft, on the structure of the product by SEM, XRD and IR were used to characterize the; and on the basis of small-scale process requirements, conceptual design of production process, calculation of the design process, first of all to the main material balance, heat balance and equipment, according to the requirements and characteristics of the operation process, with reference to the relevant process information, process flow diagram, and then according to the technological calculation structure design of the final data to draw a map of major equipment, and equipment selection, drawing workshop layout. Technical scheme to meet the requirements of safety production, economic and reasonable as the principle.
