Patent number: 5989332Abstract: A slurry containing water, carbonate-containing pigment, and dispersant consisting of 25-70 % by weight of agglomerated carbonate-containing pigment, 0.1-1.0% by weight of a dispersant, the balance being water up to 100%, can be used advantageously in papermaking as well as in the paint and lacquer industry. In a novel process for agglomerating ultra-fine particles in slurries the slurry is subjected to heat treatment until the agglomeration is complete.Type: GrantFiled: July 24, 1998Date of Patent: November 23, 1999Assignee: Pluess-Staufer AGInventors: Hans-Joachim Weitzel, Claude Wermuth, Dieter Strauch

Patent number: 5873935Abstract: A coating color comprising 28-51% by weight of water, 43-64% by weight of carbonate-containing pigment with a specific particle distribution and a particle diameter of 0.18-0.28 .mu.m and a specific surface area of 19-26 M.sup.2 /g and 6-8% by weight of conventional binding agents and additives may be employed with advantage for coated papers. The coating color is produced by wet milling of the carbonate-containing pigment without the addition of dispersing or wetting agents at a solids concentration of 30-20% by weight in an agitating ball mill, subsequent concentration, re-dispersal and the addition of binding agents, water and additives.Type: GrantFiled: March 7, 1997Date of Patent: February 23, 1999Assignee: Pluss-Staufer AGInventors: Max Schachenmann, Dieter Strauch

Patent number: 5533678Abstract: A method for the production of natural and/or synthetic carbonates, and more particularly calcium carbonates, with a high BET/N.sub.2 specific surface area of over 20 m.sup.2 /g, and more particularly of between 20 to 50 m.sup.2 /g, utilizes an inherently known mill such as an agitating ball mill. The carbonates in an aqueous suspension are wet ground and the entire suspension is recirculated; that is, subjected to additional wet grinding, until the final product has the desired specific surface area. Furthermore, the solids concentration during the entire duration of the wet grinding operation is maintained at no more than 24% by weight. The products of the method have surprisingly valuable properties and can be employed in the plastics industry, in sealants, in the rubber industry, in printing inks, in cosmetics, in pharmaceuticals, in cigarette paper, in wood varnishes, in high gloss paper and in plastisols.Type: GrantFiled: January 5, 1994Date of Patent: July 9, 1996Assignee: Pluess-Staufer AGInventors: Dieter Strauch, Peter Belger

Patent number: 4212674Abstract: A material especially adapted for incorporation in a coating composition, for example, as a secondary pigment, and characterized in having corrosion inhibiting properties. The material consists of finely particulate material on which is coated a film of fatty amine or fatty amine salt. The material coated on the particles is characterized in having a high area to volume ratio and the properties thereof in respect of inhibiting corrosion are thereby enhanced. The particulate material is advantageously natural crystalline calcium carbonate.Type: GrantFiled: June 4, 1973Date of Patent: July 15, 1980Assignee: Pluss-Staufer AGInventor: Dieter Strauch
