GENERAL INFORMATION The information below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 PROCEDURE FOR DETERMINATION OF RESINS, SOLIDS,
10、AND MOLYBDENUM DISULFIDE Weigh a known quantity of the material (A) into a tared centrifuge tube, and centrifuge at 2100 rpm for 30 minutes. Decant the liquid into a tared beaker, and add chloroform to the centrifuge tube. After shaking vigorously for several minutes, centrifuge at 2100 rpm for 30 m
11、inutes, and decant into the beaker; repeat. Dry the contents of the beaker and the centrifuge tube for four hours at 104 C. Determine the mass of the resins in the beaker (B) and the solids in the centrifuge tube (C). Weigh 0.1 to 0.2 g (D) of the solids remaining from the Molykote 106 extraction in
12、to a tared crucible, and place in a muffle furnace for eight hours at 1000 F. Determine the amount of molybdenum trioxide residue in the crucible (E). Calculate the amount of molybdenum disulfide as: (E) (1.112) (C) (100%) = % MoS2 - (D)(A) Calculate the amount of resins as: (B) (100%) = % resins - (A) Calculate the amount of solids as: (C) (100%) = % solids - (A)
