Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foaming agents for civil engineering-construction materials lack stability when mixed with inorganic materials like soil and sand, leading to instability in bubble formation and performance.
Innovation Solution
A foaming agent composition comprising an anionic surfactant (Component A), a surfactant aid (Component B), and a water-insoluble or slightly water-soluble nonionic surfactant (Component C), optimized for improved solubility, foamability, and stability, with specific carbon chain lengths and oxyalkylene group additions, to form stable bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional foaming agents are used for civil engineering-construction materials, then bubble generation is achieved, but bubble stability deteriorates when mixed with inorganic materials like soil and sand
Solution Approach 1:
The patent uses a composite foaming agent system combining three different surfactant types (anionic surfactant, amphoteric surfactant, and nonionic surfactant) with specific carbon chain lengths. This multi-component composite approach creates synergistic effects that enhance bubble stability while maintaining compatibility with inorganic materials like soil and sand, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent optimizes specific parameters including the carbon chain length of surfactants (C12-C22), the molecular structure characteristics, and the ratio components to achieve optimal bubble stability. By carefully controlling these parameters, the foaming agent maintains reliable performance when mixed with inorganic materials, simultaneously improving both reliability and adaptability.
2Productivity
If foaming agents are designed for high foamability, then bubble generation efficiency is improved, but stability until mixing with civil engineering-construction material deteriorates
Solution Approach 1:
The patent employs a composite surfactant system with three distinct components that work synergistically. The anionic surfactant provides high foamability, while the amphoteric and nonionic surfactants contribute to foam stability. This composite material approach allows the system to achieve both high productivity in bubble generation and stable composition maintenance until mixing with construction materials.
Solution Approach 2:
The patent assigns different functional qualities to different surfactant components within the system. The anionic surfactant with specific carbon chains is optimized for foam generation efficiency, while the amphoteric and nonionic surfactants are optimized for stability. This local quality differentiation within the composite system allows simultaneous achievement of high productivity and composition stability.
