Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-dust and fluxing agents are either non-biodegradable, contaminate the environment, or have insufficient weather resistance, and current methods to mitigate dust formation are inefficient and costly.
Innovation Solution
A formulation using monoglycerides, diglycerides, and fatty methyl esters derived from renewable sources, which are self-emulsifiable and self-solvent, providing dual anti-dust and fluxing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If petrochemical solvents are used as fluxing agents, then the bitumen dissolving capability and viscosity control are improved, but the environmental contamination and biodegradability are worsened
Solution Approach 1:
The patent changes the chemical composition parameters by replacing petrochemical solvents with fatty acid methyl esters (FAMEs) derived from renewable sources. This substitution maintains the essential fluxing functions (bitumen dissolution and viscosity control) while improving biodegradability and reducing environmental contamination, directly addressing the contradiction between performance and environmental harm.
Solution Approach 2:
The invention creates a composite fluxing formulation combining FAMEs with specific additives (surfactants, viscosity regulators, coalescents) in defined proportions. This composite approach enables the achievement of reliable bitumen dissolving capability while maintaining environmental sustainability through the use of biodegradable components.
2Object-affected harmful factors
If water spraying is used to prevent dust formation, then the dust suppression is improved, but the water consumption and soil erosion are worsened
Solution Approach 1:
The patent changes the physical state and composition parameters by using emulsified fatty acid methyl esters instead of liquid water for dust suppression. The emulsion formulation provides sustained dust control while reducing water consumption and preventing soil erosion, resolving the contradiction between effective dust suppression and water resource depletion.
3Object-affected harmful factors
If blonde glycerin is used for dust prevention, then the dust control is improved, but the cost is worsened
Solution Approach 1:
The patent changes the chemical composition by replacing expensive blonde glycerin with fatty acid methyl esters derived from agricultural by-products. This substitution maintains effective dust control capabilities while significantly reducing material costs, addressing the contradiction between dust control performance and economic feasibility.
4Object-affected harmful factors
If inorganic substances are used as dust control agents, then the dust suppression is improved, but the environmental pollution is worsened
Solution Approach 1:
The patent changes the chemical origin and composition parameters by replacing inorganic dust control substances with organic fatty acid methyl esters from renewable sources. This substitution maintains effective dust suppression while improving environmental compatibility and reducing pollution, resolving the contradiction between dust control effectiveness and environmental harm.
