Solution Overview
Problem
Refractory concretes with high density face challenges in water drainage during drying, leading to potential explosions due to steam pressure exceeding mechanical resistance, and existing solutions either extend drying time or compromise mechanical properties.
Innovation Solution
A composition comprising 20-70% aluminum organic acid, 3-20% deflocculant, and 7-44% mineral oxide, which improves permeability and reduces explosion risks while maintaining mechanical strength and workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If refractory concretes are made with high density to improve corrosion resistance, then corrosion resistance is improved, but water drainage during drying deteriorates
Solution Approach 1:
The invention changes the chemical composition parameters by introducing a specific adjuvant containing aluminum organic acid, deflocculant, and mineral oxide. This modifies the pore structure and surface properties of the dense refractory concrete, enabling improved water drainage without reducing density or compromising corrosion resistance.
Solution Approach 2:
The adjuvant acts as an intermediary substance that facilitates water drainage in dense refractory concretes. It contains deflocculants that prevent particle aggregation and create channels for water escape, while aluminum organic acid and mineral oxide components work together to maintain both density and drainage capability.
2Productivity
If heating temperature is increased to speed up drying process, then productivity is improved, but explosion hazard increases
Solution Approach 1:
The adjuvant is incorporated into the refractory concrete formulation before drying begins. It pre-establishes drainage channels and modifies the pore structure in advance, enabling safe and efficient water removal during subsequent rapid heating without causing steam explosions.
Solution Approach 2:
The invention converts the potentially harmful effect of trapped water under rapid heating into a beneficial drainage system. The adjuvant components create controlled pathways that guide water and steam escape, transforming what could be an explosion hazard into an efficient drying mechanism.
3Ease of operation
If polymer fibers are added to improve permeability, then water drainage is improved, but mechanical resistance deteriorates
Solution Approach 1:
The adjuvant employs a composite formulation combining aluminum organic acid, deflocculant, and mineral oxide in specific proportions. This composite approach creates synergistic effects that improve permeability through chemical and physical mechanisms without introducing foreign materials that would compromise mechanical strength.
