Segmented Detergent Block for Controlled Dissolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid block detergents for industrial warewashing applications face issues due to the incompatibility and differential solubility of peroxide sources and peroxidation catalysts, leading to unsuitable dissolution during multiple washing cycles.
Innovation Solution
A solid block detergent composition with prismatic or cylindrical domains of different chemical compositions, where the inner domains contain peroxides and the outer domains contain a peroxidation catalyst, allowing for simultaneous and controlled dissolution when sprayed with water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If peroxide source and peroxidation catalyst are blended together in a solid detergent block, then the detergent can be applied as a single solid block in warewashing machines, but the incompatible components react unfavorably due to high mutual reactivity
Solution Approach 1:
The detergent block is segmented into multiple domains with different chemical compositions. Each domain contains specific components (peroxide source in one domain, peroxidation catalyst in another domain) that are physically separated to prevent unwanted reactions while maintaining the ability to function as a single solid block during application.
Solution Approach 2:
Different regions of the detergent block have different chemical compositions tailored to specific functions. The peroxide-containing domains and catalyst-containing domains are distributed throughout the block structure, allowing each local region to contribute its specific chemical properties without causing harmful interactions in other regions.
2Object-generated harmful factors
If different phases with different components are used in block detergents, then component compatibility is improved, but the different phases do not dissolve simultaneously in industrial warewashing applications
Solution Approach 1:
The dissolution parameters of different domains are adjusted to ensure simultaneous dissolution. This is achieved by controlling the solubility characteristics of the solidified powder in each domain through selection of appropriate chemical substances and their ratios, ensuring that all domains dissolve at comparable rates under the same washing conditions.
3Adaptability or versatility
If incompatible components are brought together in a solid block, then the detergent composition can include both peroxide source and catalyst, but the components have high mutual reactivity
Solution Approach 1:
The detergent block is segmented into multiple domains with different chemical compositions. Each domain contains specific components (peroxide source in one domain, peroxidation catalyst in another domain) that are physically separated to prevent unwanted reactions while maintaining the ability to function as a single solid block during application.
Solution Approach 2:
The solidified powder acts as an intermediary medium that allows both peroxide source and catalyst to coexist in the same detergent block. The solidified powder matrix provides a stable environment that prevents direct contact and reaction between the incompatible components until dissolution occurs during use.
