Development and application of the microemulsion composite materials with biobased additives
Any kind of metal mechanical alterations is accompanied by use of metalworking fluids (MF). These fluids are generally multipurpose materials, which provide removal of metal debris from operation zone, cooling of equipment details, prevention of wear and corrosion during the metalworking. Hence, use of MF increases productivity, accuracy and purity of processing and, in many cases, decreases duration and a number of manufacturing steps. Among the most promising AMF are microemulsions. Microemulsions are superdipersed systems, which contain nanoscale droplets in a bulk phase and, in contrast to macroemulsions, have both thermodynamic and kinetic stability, thus, they are steady in time. This stabilization effect is a consequence of extra-low interfacial tension between water and oil phases that usually is provided by the mixture of surfactants.
