Antifouling Composition Using Thiol Inhibitors and Pyrion Compounds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antifouling technologies are inadequate in providing a synergistic effect against fouling organisms, such as algae, fungi, and bacteria, on surfaces exposed to water, leading to surface deterioration, increased weight, and functional impairment of objects and systems.
Innovation Solution
A combination of thiol group modulating enzyme inhibitors like dichlofluanid, tolylfluanid, or zineb with pyrion compounds like 1-hydroxy-2-pyridinone, pyrion disulfide, and sodium pyrithione, in specific proportions, is used to create a synergistic antifouling effect, inhibiting the attachment, settlement, and growth of fouling organisms on surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing antifouling technologies are used, then some level of protection against fouling organisms is provided, but the protecting effect is inadequate and surfaces still deteriorate
Solution Approach 1:
The patent combines two different antifouling agents (thiol group modulating enzyme inhibitors and pyrion compounds) into a single composition to achieve synergistic effects. This merging of different chemical mechanisms provides enhanced protection against fouling organisms while preventing surface deterioration, resolving the contradiction between adequate protection and surface integrity.
Solution Approach 2:
The invention creates a composite antifouling composition by formulating specific combinations of dichlofluanid or tolylfluanid with pyrion compounds (1-hydroxy-2-pyridinone, pyrion disulfide, or sodium pyrithione). These composite formulations provide superior and more reliable protection compared to single agents, while maintaining surface integrity against deterioration.
2Reliability
If higher concentrations of single antifouling agents are used to improve protection, then the protecting effect increases, but the complexity of the solution and potential harm increase
Solution Approach 1:
Instead of using high concentrations of a single agent, the patent merges two different antifouling agents at optimized concentrations to achieve synergistic effects. This approach provides reliable protection while maintaining manageable composition complexity through defined formulation ratios.
3Productivity
If existing antifouling compositions are applied, then some protection is achieved, but fouling organisms still attach and settle on surfaces
Solution Approach 1:
The patent employs composite antifouling formulations combining thiol group modulating enzyme inhibitors with pyrion compounds. This composite approach provides enhanced prevention of fouling organism attachment and settlement, maintaining surface productivity while effectively countering the harmful effects of biofouling.
