AI Technical Summary
Technical Problem
Existing metalworking fluids (MWFs) suffer from microbial growth that degrades their performance over time, leading to issues such as souring, viscosity changes, and corrosion, and current biocides pose health and regulatory concerns.
Method used
A semi-synthetic metalworking fluid composition incorporating aminopropanediols as microbial growth control agents, combined with base oils, organic acids, emulsifiers, and other additives, to maintain pH and inhibit microbial growth effectively.
Benefits of technology
The composition provides improved cooling, lubricity, concentration stability, and extended shelf life while avoiding environmental and health hazards associated with traditional biocides.
