| titleOfInvention | Method of producing high dry strength paper and cardboard and paper and cardboard thus obtained |
| abstract | The invention relates to a method of producing a sheet of paper and/or cardboard and similar. According to the invention, prior to the formation of the sheet, at least two dry strength agents are added to the pulp suspension either separately in any order or mixed together and at one or more injection points, namely: a first agent corresponding to a product for Hofmann degradation in solution on a (co)polymer (hereafter referred to as a base (co)polymer) comprising at least one non-ionic monomer which is selected from the group containing acrylamide and/or methacrylamide, N,N dimethylacrylamide and/or acrylonitrile; and a second agent corresponding to a (co)polymer having an anionic charge density greater than 0.1 meq/g. The invention is characterised in that the Hofmann degradation product is an organic polymer produced at a concentration greater than 3.5 % by weight, and preferably greater than 4.5 %, and in that the first and second agents are each introduced into the pulp suspension at a concentration of between 0.01 and 2 % by weight of active polymer material in relation to the dry weight of the pulp suspension. |
