Cleaning agent composition and cleaning method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning compositions containing high concentrations of solid chlorine bleaching agents and alkaline compounds generate excessive heat when contacted with water, leading to safety issues, corrosion, and degradation of surfaces, and suffer from poor storage stability due to ingredient decomposition and container swelling.
Innovation Solution
A solid cleaning composition with a coated solid chlorine bleach and an alkaline compound, having specific chlorine and water content ranges, along with additives like metal ion scavengers and surfactants, inhibits heat generation and maintains stability during use and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high concentrations of solid chlorine bleaching agent and alkaline compound are used to remove strongly adhered dirt, then cleaning effectiveness is improved, but heat generation increases causing safety issues and surface corrosion
Solution Approach 1:
The cleaning composition is divided into separate compartments: a first container holding the solid chlorine bleaching agent and a second container holding the alkaline compound. This segmentation prevents direct contact between the two ingredients until the moment of use, thereby eliminating heat generation while maintaining high cleaning effectiveness through their combined action on stubborn dirt.
Solution Approach 2:
Water acts as an intermediary medium that dissolves both the solid chlorine bleaching agent and the alkaline compound separately in their respective containers before application. This intermediary approach allows the ingredients to be activated and mixed with water rather than being directly combined in high concentrations, reducing heat generation while preserving cleaning effectiveness.
2Productivity
If high concentrations of active ingredients are used to enhance cleaning performance, then cleaning power is improved, but storage stability deteriorates due to ingredient decomposition and container swelling
Solution Approach 1:
The composition is segmented into two separate containers, each holding one active ingredient at high concentration. This physical separation prevents chemical reactions and decomposition that would occur if both ingredients were mixed in high concentrations during storage, thereby maintaining both cleaning power and storage stability.
Solution Approach 2:
The two ingredients are prepared separately in advance at high concentrations in their respective containers. This preliminary preparation allows each ingredient to be stabilized individually before use, preventing decomposition and container swelling that would result from storing them in high-concentration mixture.
3Productivity
If high concentrations of bleaching agent and alkaline compound are combined to remove stubborn dirt, then cleaning effectiveness is improved, but corrosiveness to metal surfaces increases
Solution Approach 1:
The cleaning system is segmented into two separate containers, preventing direct contact between the bleaching agent and alkaline compound. This segmentation eliminates the corrosive interaction between these two ingredients while preserving their individual cleaning effectiveness when applied separately or mixed with water during use.
Solution Approach 2:
Water serves as an intermediary that dilutes and separates the bleaching agent and alkaline compound during the cleaning process. This intermediary approach reduces the direct corrosive interaction between high concentrations of these ingredients and metal surfaces while maintaining cleaning effectiveness through their combined action in the aqueous environment.
