Abstract:
An electrorheological material comprising a carrier fluid and an atomically polarizable particle component. The atomically polarizable particle component has a crystalline lattice structure which allows atoms to shift position with respect to each other in response to the application of an electric field. The electrorheological materials are subjected to an alternating current electric field at a frequency of at least 500 Hz. The materials exhibit substantial electrorheological activity over a broad temperature range.
Abstract:
A surface-coated rubber or plastic sliding member having a coating with excellent durability and high slipperiness,wherein the coating comprises a solid lubricant such as molybdenum disulfide, a resin matrix and a reinforcement, said resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
Abstract:
The invention concerns a nitrite-free wet dressing agent for preventing the contamination of rollers and corrosion of the rolled sheet, the dressing agent containing a carboxylic acid and an amine, characterized in that the nitrite-free aqueous wet dressing agent consists of at least 2-20 % by wt of a monovalent with 6-20 C-atoms or a divalent with 4-12 C-atoms aliphatic and/or aromatic and/or arylaliphatic carboxylic acid, 0-10 % by wt of boric acid, 0.1-10 % by wt of an N-acylated derivative of N-methylglycine of the general formula (I) in which R = a saturated or unsaturated C11-C19 alkyl group and M = H, Li, Na, K, ammonium or alkanolammonium, 0-5 % by wt of a water-hardness-complexing agent, 0-0.5 % by wt of a perfuming agent, an amine which forms a salt with said carboxylic acid in aqueous solution and which is added in a quantity such that the pH-value is between 8 and 11, the remainder consisting of water. The invention also concerns a process for finishing steel strip, using this aqueous wet dressing agent.
