Extractor cleaning agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning first responders' turnout gear are inadequate in removing toxic combustion products and chemicals, particularly those that are water-insoluble, as they may not reduce harmful substances to safe concentrations, and can damage gear components at elevated pH levels.
Innovation Solution
An aqueous-based cleaning agent with a neutral pH, incorporating a linear ethoxylate emulsifier, chelates like GLDA, and fatty acids, designed for use in extractor washing machines, effectively removes anionic, cationic, and non-ionic compounds, including water-soluble and insoluble substances, without damaging fibers or plastic lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If typical laundering conditions are used, then water-soluble chemicals can be removed, but water-insoluble combustion products and chemicals cannot be reduced to safe concentrations
Solution Approach 1:
The cleaning agent changes the chemical parameters of the washing solution by incorporating specific surfactants (linear ethoxylate emulsifier), chelates (GLDA), and fatty acids that enable the removal of both water-soluble and water-insoluble substances. This chemical parameter change allows the cleaning solution to effectively dissolve and emulsify stubborn combustion products that typical laundering cannot remove.
Solution Approach 2:
The cleaning agent uses a composite formulation combining multiple functional ingredients: linear ethoxylate emulsifier for surface activity, chelates for metal ion binding, and fatty acids for emulsification. This composite approach creates a synergistic effect that enhances the removal of diverse harmful substances including anionic, cationic, and non-ionic compounds.
2Productivity
If elevated pH detergents are used for cleaning, then cleaning power is increased, but damage occurs to fibers, coatings, and plastic lenses
Solution Approach 1:
The cleaning agent maintains a neutral pH level (between 6.5 and 8.0), which is a significant parameter change from traditional high-pH industrial detergents. This neutral pH parameter ensures that the cleaning process does not damage sensitive gear components such as plastic lenses, coatings, and fabric fibers, while still achieving effective cleaning through the action of surfactants and chelates.
3Reliability
If strong chemicals are used to remove all contaminants, then removal efficiency increases, but the cleaning agent may damage turnout gear components
Solution Approach 1:
The cleaning agent uses a neutral pH formulation that changes the chemical environment from aggressive to gentle, thereby protecting gear components while maintaining effective contaminant removal through specialized surfactants and chelating agents.
Solution Approach 2:
The cleaning agent acts as an intermediary substance that facilitates the removal of harmful chemicals without requiring direct contact between strong chemicals and the gear components. The surfactants and chelates serve as mediators that bind to contaminants and enable their removal through mild washing conditions.
