Abstract: The invention relates to a method for producing paper, paperboard and cardboard. According to said method, a polymer containing vinylamine units and a polymer anionic compound are added separately to a pulp, the pulp is decked, and the paper products are dried. At least one copolymer is used as a polymer anionic compound, said copolymer being obtained by the copolymerisation of (a) at least one N-vinylcarboxylic acid amide of formula (I) wherein R 1 , R 2 represent H or C1 to C6 alkyl, (b) at least one monoethylenically unsaturated monomer containing acid groups and/or the alkali metal, earth alkali metal or ammonium salts thereof, optionally (c) other monoethlenically unsaturated monomers, and optionally (d) compounds comprising at least two ethylenically unsaturated double bonds in the molecule.

Abstract: A process for the production of paper, board and cardboard by draining a paper stock containing interfering substances in the presence of polymers which contain vinylamine units and which have an average molar mass Mw of at least 1 million, a high-consistency stock first being prepared, at least one polymer containing vinylamine units and having an average molar mass Mw of at least 1 million and a degree of hydrolysis of from 1 to 20 mol % being metered into the high-consistency stock, the high-consistency stock being diluted to a low-consistency stock by adding water, and the low-consistency stock being drained, the polymers being hydrolyzed homo- or copolymers of N-vinylcarboxamides additives for reducing deposits in the wire part, press section and drying section of paper machines.

Abstract: A flow-through cuvette (1), through which the sample flow (2) - surrounded by an enveloping flow (3) - is passed, is equipped with an optical laser measuring device (4-7). For use in systems under pressure, a pressure and quantity stabiliser (9-11) is connected upstream of the input (8) for the enveloping flow medium of the cuvette, and a controller (13, 14, 16, 17) for the quantity of the sample flow and enveloping flow is connected downstream of the output (12) of the cuvette.

Abstract: Disclosed is a method for producing paper, paperboard, and cardboard by shearing the paper material, adding a microparticle system made of cationic polymers and a fine-particle inorganic component to the paper material following the last shearing step before agglomerating the material, dewatering the paper material so as to form sheets, and drying said sheets. Cationic polyacrylamides, polymers containing vinylamine units, and/or poly diallyl dimethyl ammonium chloride, each of which has an average molar weight Mw of at least 500,000 Dalton and a maximum charge density of 4.0 meq/g, is/are used as cationic polymers.

Abstract: The invention relates to a method for producing filled papers and filled paper products by adding an aqueous suspension of at least one finely particulate polymer-pigment hybrid to a paper-making stock and dewatering the paper-making stock while forming sheets. The polymer-pigment hybrid is obtained by grinding an aqueous suspension of at least inorganic pigment in the presence of at least one binder and optionally by drying the aqueous suspension so obtained and redispersing the dried polymer-pigment hybrid in water. The invention also relates to the polymer-pigment hybrids so obtained as fillers for producing filled paper or filled paper products.

Abstract: A process for preparation of paper, pasteboard, or cardboard involving cutting of the paper pulp, addition of microparticles of cationic polymer, and a finely divided inorganic component after the last cutting step and before pulp swelling, dewatering of the pulp, and sheet formation and drying of the sheets is new. A process for preparation of paper, pasteboard, or cardboard involving cutting of the paper pulp, addition of microparticles of cationic polymer, and a finely divided inorganic component after the last cutting step and before pulp swelling, dewatering of the pulp, and sheet formation and drying of the sheets. The cationic polymer of the microparticle system is cationic polyacrylamide, polymer containing vinylamine units, and/or polydiallyl dimethylammonium chloride containing polymer of mean mol.wt. 500,000 Dalton, and maximum charge density 4.0 meq/g, where the microparticle system free from polymers of charging density (sic) more than 4 meq/g is used as the retention agent.

Abstract: The maximum amounts of the retention-influencing variable stock components which can be added are determined as a function of a predetermined degree of flocculation and typical values of the stock suspension with the aid of a mathematical relationship, and control signals for metering retention aids are derived from the amounts so that the greatest possible retention can be achieved without exceeding a set-point for the degree of flocculation.
