Development of theoretical basics and experimental verification of progressive methods of graphite oxidation with simultaneous grinding

The first attempts of scientifically based analysis of grinding process belong to Rittinger and Kik. Results of theoretical and laboratory studies aimed to obtain finely dispersed graphite for manufacture of technological lubricants are presented. Modern very labor-intensive technology for grinding graphite is shown and its shortcomings are indicated. Theoretical analysis of possibility of changing graphite by progressive method of oxidative milling of graphite with help of hydrogen peroxide is given. Original method of laboratory research on oxidative grinding of graphite has been developed. Presented results of laboratory studies fully confirmed theoretical calculations that makes it possible to simplify process of obtaining colloidal graphite for technological lubricants. This eliminates operation of washing colloidal graphite from decomposition products of chromium mixture and sulfuric acid which takes place in manufacture of OGV lubricant.
