Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Raw polyols from biomass, such as crude glycerol, used as grinding aids in cement production often cause contamination and disruptions due to phase separation and resinization effects, which negatively impact the grinding process.
Innovation Solution
Stabilizing raw polyols from biomass using solubilizers like alkaline substances, specifically alkanolamines, to prevent phase separation and maintain a stable, homogeneous phase, thereby reducing contamination and disruptions during the grinding of mineral binders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If crude polyols from biomass are used as grinding aids, then environmental advantage and grinding efficiency are improved, but contamination of pumps and lines, disruptions in grinding, and resinification effects occur
Solution Approach 1:
The patent introduces an intermediary substance (solubilizer, surfactant, or stabilizer) to mediate between the crude polyol and the grinding system. This intermediary prevents direct harmful interactions by forming stable micellar structures that solubilize the oily components, thereby eliminating pump contamination and grinding disruptions while preserving the environmental benefits of biomass-based polyols
Solution Approach 2:
The patent converts the harmful oily components and impurities in crude polyols into beneficial micellar structures through the addition of solubilizers. These micelles actively prevent resinification and contamination by trapping hydrophobic substances, transforming what was previously harmful into a protective mechanism that enhances grinding process stability
2Adaptability or versatility
If crude polyols with oily components are used, then biomass utilization is improved, but phase separation and resinification effects occur
Solution Approach 1:
The patent changes the chemical parameters of the crude polyol system by adding solubilizers that alter the micellar structure and critical micelle concentration. This parameter change prevents phase separation by maintaining a stable micellar dispersion of oily components, allowing the system to retain full biomass utilization while achieving long-term compositional stability
Solution Approach 2:
The patent creates a composite system combining crude polyol, solubilizer, and stabilized oily components into a unified stable formulation. This composite structure prevents phase separation by integrating all components into a homogeneous micellar system, maintaining both biomass versatility and phase stability
3Stability of the object's composition
If solubilizers are added to stabilize crude polyols, then phase separation is prevented, but composition complexity increases
Solution Approach 1:
The patent employs small quantities of inexpensive solubilizers (typically 0.1-5% by weight) that perform their stabilization function efficiently without requiring complex formulations. These simple additives provide long-term phase stability through micellar mechanisms, avoiding the need for complex multi-component systems while maintaining compositional simplicity
