Sulfamic Acid Cleaning Composition for Cement Residue Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning products are ineffective for instantaneous removal of cement-based residues from tiles and grout lines during flooring installation, as they are either too corrosive, slow-acting, or not suitable for removing polymer-modified fillers, posing safety risks and requiring rinsing.
Innovation Solution
A cleaning composition comprising sulfamic acid, a glycol solvent, and water, which acts rapidly and effectively to remove cement-based residues without producing toxic fumes, allowing for simultaneous mechanical removal and quick drying without leaving residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If strong acid-based cleaning products are used, then cleaning power is improved, but toxic fumes are generated and flooring is damaged
Solution Approach 1:
The patent changes the chemical parameters of the cleaning composition by using sulfamic acid instead of strong mineral acids, and by adjusting the pH to a specific range (2-4) to achieve effective cleaning while eliminating toxic fume generation and flooring damage
Solution Approach 2:
The patent creates a composite cleaning composition combining sulfamic acid with specific surfactants and chelating agents to achieve synergistic effects that provide both strong cleaning power and safety against toxic emissions and flooring damage
2Speed
If strong acid-based cleaning products are used, then cleaning speed is improved, but mechanical action time is insufficient for effective residue removal
Solution Approach 1:
The patent creates a dynamically balanced cleaning system where the chemical action time is extended to match the mechanical action time, allowing both processes to work synergistically for complete residue removal without requiring excessive time from either method
3Object-affected harmful factors
If conventional cleaning products are used, then safety is improved, but cleaning effectiveness on polymer-modified fillers is reduced
Solution Approach 1:
The patent develops a composite formulation that integrates sulfamic acid with specific surfactants and chelating agents to create a multi-functional cleaning composition that maintains safety while achieving reliable removal of polymer-modified fillers through synergistic chemical and physical actions
