  • Publication number: 20150337101
    Abstract: Rigid polystyrene foams contain thermally treated non-graphitic anthracite coke particles. Such athermanous materials permit a more energy-efficient grinding process, wherein the ground particles are yielded in the desired platelet form and these ground particles also disperse well in a polystyrene matrix. Therefore the rigid polystyrene foams containing the anthracite coke particles have a density of less than 40 kg/m3 and a thermal conductivity of less than 40 mW/m·K which provides desired thermal insulation properties.

  • Patent number: 8782894
    Abstract: A method for producing and commissioning a transmission with a water-based lubricant comprises the following steps. A mixture of a vaporizable liquid, a comminuted solid lubricant and a preserving agent (22) are applied (21) to the finished rotary parts (20) and then dried (23), whereby a coating forms on them. The rotary parts with the coating are installed in the transmission housing and the assembled transmission is filled with a cooling liquid (25), which is primarily essentially water. The transmission is put into operation for the first time (27), wherein the lubricant for the further operation is only formed by abrasion of the rotary parts and distribution of the abraded matter in the cooling liquid. The transmission is then ready for operation (28). Furthermore, a lubricant produced by this method is described.
