FIELD: chemistry.SUBSTANCE: present invention relates to a method of producing grease by mixing a thickener and spent motor oil, wherein the thickener, which is ground in an electromagnetic grinder, has particle size of not more than 1 mcm and is obtained by ferritisation from electroplating wastes at t = 800-900°C for 1-1.5 hours in ratio of 40:60%.EFFECT: low cost of the grease owing to use of wastes and low cost of component of the grease, higher environmental friendliness owing to recycling of wastes, use of said ingredients reduces corrosiveness of the grease and widens the range of the treated material.3 ex, 3 tbl, 1 dwg |
