Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sulfonated dispersants used in industrial applications typically freeze at around 0°C, posing challenges during transportation, storage, and application.
Innovation Solution
A composition comprising a sulfonated dispersant and a solvent, such as ethylene glycol, is developed to lower the freezing point of the dispersant, allowing its use at low temperatures, with specific weight percentages of the sulfonated dispersant and solvent optimized to prevent freezing and sedimentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dispersants are used in aqueous solution form, then they maintain good dispersing performance, but they freeze at around 0°C which impacts transportation, storage, and application
Solution Approach 1:
The patent changes the physical-chemical parameters of the dispersant by adding co-solvents (alcohols, glycols, carboxylic acids) to the aqueous solution, thereby lowering the freezing point from 0°C to below -20°C while maintaining the dispersing performance. This parameter modification allows the dispersant to remain liquid and functional in low-temperature environments.
Solution Approach 2:
The patent creates a composite liquid formulation by combining the aqueous dispersant solution with multiple co-solvent components. This composite system integrates the dispersing properties of the sulfonated dispersant with the low-temperature fluidity of the co-solvents, achieving both dispersing performance and anti-freezing capability simultaneously.
2Adaptability or versatility
If the freezing point of dispersant is lowered by adding co-solvents, then the dispersant can be used at low temperatures, but the composition complexity increases
Solution Approach 1:
The patent selects co-solvents that serve multiple functions: they lower the freezing point, maintain liquidity at low temperatures, and preserve the dispersing effectiveness. By choosing substances like alcohols, glycols, and carboxylic acids that perform multiple roles, the patent reduces the need for additional components, thereby limiting the increase in composition complexity while achieving low-temperature adaptability.
