Water Evaporation Control via Polymer-Insoluble Compound Monolayer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling water evaporation from bodies such as reservoirs and dams are inefficient, particularly for large volumes, as they either require frequent re-application of monolayer structures or are unstable against wind disruption.
Innovation Solution
A method involving the application of a water-insoluble compound and a water-soluble polymer to form a stable layer at the water surface, utilizing non-covalent bonding interactions to reduce evaporation, with the polymer including carbonyl or non-carbonyl polymers and specific functional groups to enhance stability and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monolayer structures are applied to reduce water evaporation, then evaporation control is achieved, but the structures do not persist on the water surface for more than a couple of days and require frequent re-application
Solution Approach 1:
The patent combines a water-insoluble compound (forming the monolayer) with a water-soluble polymer ( providing bulk stability and wind resistance) to create a composite evaporation control system. This composite structure allows the monolayer to persist on the water surface for extended periods while resisting wind disruption, resolving the contradiction between initial evaporation control effectiveness and long-term persistence.
2Reliability
If monolayer structures are applied to control evaporation, then water loss reduction is achieved, but the structures are unstable against wind disruption
Solution Approach 1:
The water-soluble polymer acts as an intermediary substance that connects the monolayer structure to the bulk water phase. This intermediary provides anchoring and stabilizing forces that protect the monolayer from wind disruption, allowing the system to maintain evaporation control stability under windy conditions while the monolayer itself remains intact.
3Reliability
If physical covers are used to reduce water evaporation, then evaporation control is achieved, but they are not practical for large volumes of water such as reservoirs and large dams
Solution Approach 1:
The patent employs thin film monolayer structures formed by water-insoluble compounds that can be easily applied to large water bodies. These flexible thin films cover the water surface without requiring rigid support structures, making them practical for large-scale applications such as reservoirs and dams while maintaining effective evaporation control.
