Solution Overview
Problem
Existing semi-synthetic cutting fluids face challenges with corrosion and rust prevention, lubrication, and antibacterial properties, particularly due to high costs and limited additive options, and nano copper particles tend to agglomerate in cutting fluids, reducing their effectiveness.
Innovation Solution
The use of self-dispersible nano copper with an organic long-carbon chain coating, such as dialkyl dithiophosphate, which substitutes functional additives like preservatives, anti-rust agents, and lubricants, allowing stable dispersion in cutting fluids and enhancing anti-corrosion, anti-rust, compression-resistant, and lubricating properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-rust agents and lubricants are used in semi-synthetic cutting fluids, then corrosion and rust prevention as well as lubrication are achieved, but the cost increases and the formula complexity increases
Solution Approach 1:
The patent applies multi-functionality by using nano copper particles as a single additive that simultaneously provides anti-rust, lubrication, and antibacterial properties. This replaces multiple separate conventional additives (anti-rust agents, lubricants, sterilizing agents), thereby reducing formula complexity while maintaining or improving performance.
Solution Approach 2:
The patent merges multiple functional properties into one nano copper additive. Instead of using separate anti-rust agents, lubricants, and sterilizing agents, the nano copper particles combine these functions, simplifying the overall formula and reducing the number of components needed.
2Reliability
If conventional additives are used in large amounts to achieve sufficient performance, then the required protection levels are met, but the production cost increases
Solution Approach 1:
The patent changes the physical and chemical parameters of the additive by using nano-scale copper particles instead of conventional macro-scale additives. The nano-scale dimension provides significantly higher surface area to volume ratio, enhancing effectiveness per unit mass, thus reducing the total quantity of additive needed while maintaining protection levels.
Solution Approach 2:
The patent uses composite material approach by combining copper nanoparticles with specific surface treatments or coatings to achieve multi-functional properties. This composite structure enhances the effectiveness of the additive, allowing lower concentrations to achieve the required protection levels.
3Reliability
If nano copper particles are added to cutting fluid, then multi-functional performance is enhanced, but the particles tend to agglomerate reducing effectiveness
Solution Approach 1:
The patent uses surface treatments or coatings on the nano copper particles as intermediary layers that prevent direct aggregation between particles. These surface modifications act as mediators that maintain particle separation and stability in the cutting fluid, preventing agglomeration while preserving the multi-functional benefits.
Solution Approach 2:
The patent applies thin film coatings on the nano copper particle surfaces to prevent agglomeration. These flexible surface films or shells maintain particle dispersion stability in the cutting fluid, allowing the particles to remain effectively distributed while retaining their core functional properties.
