Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for synthesizing basic copper chloride result in products with inconsistent copper content and particle size, leading to issues like fugitive dust and agglomeration, which do not meet industry standards.
Innovation Solution
A method to produce basic copper chloride particulate matter with a particle size of 60 μm to 250 μm, comprising at least 97% of the total mass, using a preparation process that involves adjusting the copper concentration in waste etching liquids and maintaining a specific pH range to ensure high copper content and stability, avoiding the use of adhesives and promoting the atacamite or paratacamite crystal form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional parallel feeding synthesis method is used, then the synthesis process is simple, but the particle size is too small and copper content is inconsistent
Solution Approach 1:
The patent applies preliminary action by conducting impurity removal and copper content adjustment on waste etching liquids before the synthesis reaction. This pre-treatment ensures that the raw materials have consistent copper content (1-5 g/L) and controlled pH ranges, which directly leads to uniform particle size (60-250 μm) and high copper content (≥58.12%) in the final product, resolving the particle size consistency issue while maintaining process simplicity
Solution Approach 2:
The patent employs parameter changes by precisely controlling the pH value during synthesis (maintaining pH 2-4 through hydrochloric acid or ammonium chloride addition) and adjusting copper content in the waste etching liquids. These parameter controls ensure consistent reaction conditions, producing basic copper chloride with uniform particle size distribution and high copper content, thereby improving manufacturing precision without complicating the synthesis process
2Length of moving object
If adhesive bonding method is used to increase particle size, then the particle size increases, but the copper content decreases below standard
Solution Approach 1:
The patent applies the taking out principle by completely eliminating adhesive agents from the synthesis process. Instead of using adhesives to bond particles, the method synthesizes basic copper chloride directly through controlled chemical reaction between copper-containing solutions and alkaline solutions, with impurity removal and pH control. This extraction of harmful adhesives ensures the product achieves both large particle size (60-250 μm) and high copper content (≥58.12%), meeting national standards without dilution
Solution Approach 2:
The patent implements self-service by using the waste etching liquids themselves as the primary copper source after impurity removal and concentration adjustment. The copper content in the waste liquids is optimized to 1-5 g/L, and through controlled synthesis with alkaline solutions, the basic copper chloride particles form with desired size and high copper content naturally, without requiring external adhesive materials that would reduce copper content
3Ease of manufacture
If small particle size basic copper chloride is used, then the synthesis is easier, but fugitive dust occurs during use
Solution Approach 1:
The patent applies parameter changes by controlling the synthesis conditions (pH 2-4, temperature 20-100°C, controlled addition rates) to produce basic copper chloride particles with optimized size distribution (60-250 μm). This parameter control ensures particles are large enough to minimize dust generation during handling and use, while maintaining synthesis feasibility and high copper content (≥58.12%), thus resolving the conflict between synthesis ease and dust prevention
