Development of the Formulation of Technological Liquid Using Powders of Aluminum and Titanium Oxides
Abstract
The particle sizes of Al2O3 and TiO2 powders selected for the development of the coolant formulation were analyzed using the Microsizer 201C laser diffraction particle analyzer. It was found that the number of nanoparticles in aluminum oxide powder is 4%, and particles in the micro-range of 10-20 microns have the largest total specific surface area. The TiO2 powder is dominated by nanoparticles (more than 90%). The choice of the basic components of coolant for resistance to fungal infection is justified. Conducted studies on the main indicators (anticorrosive properties, acid number, bio-contamination) of 8 samples of technological liquid with the developed formulation, compliance with the requirements for emulsion COOLANT was shown.
