Decontamination Composition Stability via Suspended Oxidizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decontamination/detoxification products for surfaces contaminated with toxic and pathogenic substances are prone to phase separation when stored, leading to clogging and reduced effectiveness, which is critical in emergency situations where time is a factor and can result in personal injuries and equipment damage.
Innovation Solution
A decontamination/detoxification composition comprising 10% to 40% oxidizing agent (potassium or sodium isocyanurate dichloride/trichloride), 8% to 35% alkalinizing agent, 30% to 70% inorganic filler, and 0.5% to 5% suspending agent, ensuring high solubility and stability, minimizing phase separation and clogging, and maintaining efficiency over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If decontamination/detoxification products are stored in a tank for a relatively long time without stirring, then stability is improved, but phase separation occurs leading to clogging and equipment damage
Solution Approach 1:
A suspending agent is introduced as an intermediary substance to prevent phase separation between the solid decontamination product and the liquid carrier. This mediator maintains uniform distribution of components in the storage tank, eliminating settlement and subsequent clogging issues while allowing long-term storage without stirring.
2Loss of time
If decontamination/detoxification products are used in emergency situations, then response time is reduced, but phase separation and clogging can lead to personal injuries and damages
Solution Approach 1:
The suspending agent is incorporated into the product formulation in advance to prevent phase separation during storage and transport. This preliminary protective action ensures that when the product is deployed in emergency situations, it remains homogeneous and free-flowing, preventing clogging that could delay response or cause equipment failure and personal injury.
3Device complexity
If solid and liquid phases separate in the storage tank, then storage is simplified, but effectiveness of reclaiming decreases over time
Solution Approach 1:
The suspending agent acts as a mediator that maintains phase uniformity during storage without complicating the storage system. It allows the product to remain stable and effective over time while requiring no additional storage infrastructure or active mixing mechanisms, thus preserving storage simplicity while ensuring consistent reclaiming effectiveness.
