    摘要: In a method for preparing polyaniline, aniline is polymerized in a reactor in a polymerization medium containing aniline and oxidant. The polymerization is performed in a reactor in which the ratio of the heat transfer surface to the reaction volume is at least 10/m, preferably at least 20/m. In the apparatus, the polymerization is performed in a tubular reactor by allowing a medium containing aniline and oxidant to flow in a mixed flow through the tubular reactor. The tubular reactor is equipped with static mixers, and there can be several tubular reactors in parallel.

    摘要: A method for calendering a web such as a paper web in a multi-nip calender or supercalender, in which the web is passed through calendering nips formed by rolls placed in two or more stacks of rolls. The web is passed alternatingly from the corresponding calendering nip in each stack of rolls into the calendering nip in the following stack of rolls. In other words, the web is passed from a first calendering nip in a first stack of rolls to a first calendering nip in a second stacks of rolls, after the first calendering nip in the second stack of rolls to a second calendering nip in the second stack of rolls, from the second calendering nip in the second stack of rolls to a second calendering nip in the first stack of rolls, and after the second calendering nip in the first stack of rolls to further processing.

    摘要: A jet coating apparatus and method for applying coating mix onto a moving web in a noncontacting manner in ambient pressure. The apparatus includes an upper lip placed close to the web, a lower lip situated in the vicinity of the upper lip and arranged essentially on the trailing side relative to the moving direction of the web. The slot orifice bounding surface of the upper lip and the slot orifice bounding surface of the lower lip form a slot orifice suited for feeding the coating mix onto the web. In the slot orifice, at least the directional vector along the slot orifice surface of the lower lip has a vector component opposite to the tangential velocity vector of the web.

    摘要: The invention concerns a procedure for manufacturing solid catalyst components for catalysts serving polymerization of alpha-olefines, having a solid carrier substance containing an organic or inorganic magnesium compound and treated with a titanium halide and optionally with an electron donor compound. The magnesium compound or the mixture of magnesium compound and electron donor compounds is sprayed in molten state into a chamber or volume which has been cooled to a temperature at which the catalyst component will solidify from the melt in the form of particles with generally spherical shape, without any substantial evaporation of solvents.

    摘要: A multilayer curtain coater for coating a moving material web, such as a paper or board web, with coating material, in which an application device is arranged above a material web having an upper surface, the web being mounted for motion with respect to the curtain coater, and the web arranged so that a coating material feeds onto the surface of the web in a curtain-like flow. The curtain coater has a scraper with a scraper surface which engages the upper surface of the web to remove an air boundary layer thereon. The durability of the scraper surface is increased by constructing the scraper out of a hard wear resistant material or material which is surface-hardened or provided with a durability-enhancing coating layer.

    摘要: A method and apparatus for coating a moving web of paper or paperboard. The web to be coated is passed to a coater station, wherein a coat layer is applied to at least one surface of the web by means of high-pressure spraying nozzles, whereby the pattern width covered by a single nozzle is essentially narrower than the cross-machine width of the web being coated. The nozzles are located in an enclosure and the excess coat mist formed in the process is removed by means of suction tubes, and advantageously, with the help of a falling film of coating mix flowing down the internal wall(s) of the enclosure.
