Extruded Ceramic Glaze Additive Pellets for Dust-Free Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ceramic glaze slips face issues with powdery additives that cause environmental and health hazards, are difficult to dissolve, and lead to handling problems, dust generation, and defects in final products due to uneven dissolution and dosing.
Innovation Solution
The use of extruded pellets comprising carboxymethyl cellulose and other ceramic glaze additives, which are compact, dust-free, and have controlled composition and dimensions, simplifying handling and dosing, and reducing lump formation and dust generation during processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If powdery additives are used in ceramic glaze slips, then the glaze can be formulated with necessary components, but dust generation and environmental/health problems occur
Solution Approach 1:
The patent transforms the physical state of additives from powder to extruded pellet form. This parameter change in morphology eliminates dust generation while maintaining the chemical composition and functionality of the additives in ceramic glaze slips.
Solution Approach 2:
The patent creates composite extruded pellets that combine multiple ceramic glaze additives (such as carboxymethyl cellulose, suspending agents, thickening agents) into a single integrated carrier. This composite structure delivers multiple functional components without the dust problems associated with separate powdery additives.
2Reliability
If powdery additives are used in ceramic glaze slips, then the glaze can achieve required properties, but dissolution difficulties and lump formation occur
Solution Approach 1:
The patent changes the physical form of additives from fine powder to extruded pellets with controlled size and porosity. This parameter change improves dissolution characteristics by providing a balanced surface area-to-volume ratio that allows complete dissolution without lump formation, while maintaining the reliability of glaze slip quality.
Solution Approach 2:
The extruded pellets are pre-formed with optimal physical characteristics (size, porosity, density) before being added to the glaze slip. This preliminary preparation ensures that the additives will dissolve uniformly and completely during the mixing process, eliminating the need for extensive stirring and preventing manufacturing difficulties.
3Measurement precision
If powdery additives are used in ceramic glaze slips, then the glaze can be formulated, but dosing precision and handling difficulties occur
Solution Approach 1:
The patent transforms additives from powdery form to extruded pellets with standardized size, shape, and density parameters. This parameter change enables precise dosing through simple weight or volume measurements and improves handling characteristics by eliminating dust generation and static electricity problems associated with fine powders.
