Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow removal agents containing high chloride salts cause environmental pollution, corrosion, and are costly, while achieving limited reduction in chloride content.
Innovation Solution
A snow removal composition comprising 11.000 to 22.000 wt% chloride salt, 0.05 to 0.200 wt% metasilicic acid or metasilicate, 0.050 to 10.000 wt% formic acid or formate, and the remainder water, with optional acetic acid or acetate and glycerin, to achieve effective ice melting and corrosion resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional deicing materials (rock salt, calcium chloride, ammonium nitrate) are used, then ice melting capability is improved, but environmental pollution and corrosion damage increase
Solution Approach 1:
The invention changes the chemical composition parameters by using magnesium chloride hexahydrate as the primary deicing agent instead of conventional rock salt or calcium chloride, and by incorporating specific ratios of additives including organic acids (sodium citrate, sodium lactate), inorganic salts (potassium chloride, calcium nitrate), and surfactants to achieve effective ice melting while reducing environmental harm and corrosion
Solution Approach 2:
The invention creates a composite deicing formulation by combining magnesium chloride hexahydrate with multiple additives including organic acids, inorganic salts, and surfactants in specific proportions, where each component contributes different functions: magnesium chloride provides primary deicing capability, organic acids inhibit corrosion and provide antifungal effects, and surfactants enhance spreading and adhesion properties
2Productivity
If high concentrations of deicing chemicals are applied, then ice removal effectiveness is improved, but ecological damage and soil water contamination increase
Solution Approach 1:
The invention converts potentially harmful high-concentration chemicals into a beneficial formulation by using magnesium chloride hexahydrate which, even at effective concentrations, provides corrosion inhibition through film-forming additives and creates a less harmful residue that can actually benefit soil structure and plant growth compared to conventional deicers
3Ease of manufacture
If traditional deicing formulations are used, then cost-effectiveness is improved, but environmental safety deteriorates
Solution Approach 1:
The invention uses readily available, low-cost raw materials including magnesium chloride hexahydrate, common organic acids like citric and lactic acid, and standard surfactants that can be purchased from conventional chemical suppliers, making the environmentally safe formulation as cost-effective as traditional deicers while providing superior environmental performance
