Phosphate-Free Surface Treatment Composition for Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface treatment compositions often contain phosphates, which, despite their strong cleaning performance, harm freshwater bodies by promoting excessive algae growth, leading to environmental damage and prompting regulatory bans, and can also alter the characteristics of treated surfaces, particularly harming metal-plated fixtures and paint surfaces.
Innovation Solution
Development of surface treatment compositions that significantly reduce or eliminate phosphate content, using formulations like those listed in Tables 1 through 10, which include citric acid, Lutropur MSA, Purac HS, Glycolic Acid, and other raw materials, applied to surfaces to effectively remove deposition materials without altering their characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If phosphates are used in surface treatment compositions, then cleaning performance is improved, but environmental harm increases and surface characteristics are altered
Solution Approach 1:
The patent removes phosphates from the cleaning composition formulation. The composition explicitly excludes phosphates while maintaining effective cleaning performance through alternative ingredients such as citric acid, lactic acid, and other chelating agents that can bind metal ions and dissolve deposits without the environmental harm associated with phosphates.
Solution Approach 2:
The patent changes the chemical composition parameters by substituting phosphate-based cleaning agents with alternative acid-based ingredients. This parameter change maintains the cleaning function while eliminating the harmful environmental effects and surface alteration problems caused by phosphates.
2Object-affected harmful factors
If phosphates are eliminated from surface treatment compositions, then environmental harm is reduced, but cleaning performance may be compromised
Solution Approach 1:
The patent combines multiple alternative cleaning ingredients including citric acid, lactic acid, and other chelating agents to achieve the cleaning performance previously provided by phosphates. This combination of ingredients works synergistically to remove deposits while being environmentally safe.
Solution Approach 2:
The patent uses a composite formulation consisting of multiple organic acids and chelating agents instead of a single phosphate-based ingredient. This composite approach allows the composition to achieve effective cleaning through the combined actions of different ingredients that can chelate metal ions and dissolve various types of deposits.
3Productivity
If conventional cleaning compositions are used, then deposition materials are removed, but surface characteristics are altered or damaged
Solution Approach 1:
The patent removes harsh chemicals from the formulation that would alter or damage surface characteristics. By excluding phosphates and using milder organic acids instead, the composition effectively removes deposition materials while preserving the integrity and original characteristics of the treated surface.
Solution Approach 2:
The patent changes the pH and chemical composition parameters to use milder organic acids that are less likely to damage surfaces. This parameter adjustment allows effective cleaning while maintaining surface stability and preventing alteration of surface characteristics.
