Abstract : The report discusses a method for manufacturing a saponification mixed sodium calcium lubricating grease characterized by the fact that first runnings of fatty acids, last running of fatty acids and lime are mixed together and heated to 75C, the lye is slowly added and after saponification the solution is cooked at 120C and subsequently the amount of residual oil is added and the solution is again heated to 110C and then allowed to stand in the unheated vessel. Saponification mixed sodium calcium lubricating grease is characterized by the fact that it consists of the following raw materials: 9.10 g first runnings fatty acid, saponification number 382.49 mg KOH/g, 89.50 g last runnings fatty acid, saponification number 170.2 mg KOH/g, 76.00 g spindle oil, 34.00 g sodium aluminum solution, Alk. 266.65 KOH/g, 22.25 g Ca(OH)2.
