The invention relates to polyurea lubricating grease compositions containing polyurea thickeners and at least one organic carbonate, to lubrication points or components containing the polyurea lubricating grease composition, to a seal comprising sealing material from fluorinated elastomers and to the use of the lubricating greases.

Polyurea lubricating greases containing carbonates, and their use

An inorganic binder for the production of ceramic, glass ceramic and other mineral materials and composite materials comprises at least one inorganic compound having a mean particle size of &#x3c;100 nm and at least one solvent. The inorganic compounds are preferably compounds selected from the group consisting of the chalcogenides, the carbides and/or the nitrides. Further preference is given to the mean particle size being &#x3c;50 nm, in particular &#x3c;25 nm. The solvent is, in particular, a polar solvent, especially water.

Production of ceramic, glass ceramic and other mineral materials and composite materials

The invention concerns a method for producing a highly-porous ceramic layer and for application of this layer onto metallic, ceramic, enameled and/or glass substrates using porous, ceramic particles, preferably aluminum oxide, titanium oxide and zircon oxide, and an inorganic binder system. The inorganic binder system contains at least one ceramic nanoparticle of a particle size of less than 100 nm, preferably less than 50 nm and particularly preferred less than 25 nm, the solvent being water. Layers produced in this fashion are suited as self-cleaning catalytically active layers e.g. in ovens, in combustion engines etc. or for general coating of substances to considerably increase their specific surface e.g. for catalytic substrates.

Method for producing self-cleaning ceramic layers and a composition therefore

In a filtration device () comprising a pressure-resistant housing () with a liquid inlet opening () and an outlet opening () for filtered matter, into which a collecting channel () terminates, at least one filter element () designed as flat membrane is connected to the collecting channel () in a pressure-tight manner. This device provides a high liquid throughput at the same time having a compact construction.

Filtration device

The invention concerns a method for producing porous ceramic layers on metallic, ceramic, enameled or glass substrates using crystalline nanoparticles of particle sizes of between 3 nm and 100 nm via a wet-chemical process and functionalising of this porous ceramic layer through introducing a second component into the pores of the porous ceramic layer which serves as carrier layer. The porous ceramic layers can be filled with hydrophobizing, hydrophilizing, dirt-repellent and corrosion-inhibiting substances which remain in the substrate or are supplied later on demand, or with bactericidal substances, aromatics, perfumes or inhalation substances which are delivered to the room air in precise doses.
