Abstract
Amélioration aux procédés de fabrication des papiers et des cartons consistant à ajouter à n'importe quel stade du procédé, avant la formation de la feuille de papier, un sel basique de formule : Mn (OH)m X3n-m dans laquelle M est un métal tri- ou polyvalent, par exemple Al, Cr ou Fe, X est Cl, NO3 ou CH3 COO, n et m sont des nombres positifs tels que 3n-m > 0 et que le rapportImprovement to paper and board manufacturing processes consisting in adding at any stage of the process, before the formation of the paper sheet, a basic salt of the formula: Mn (OH) m X3n-m in which M is a tri- or polyvalent metal, for example Al, Cr or Fe, X is Cl, NO3 or CH3 COO, n and m are positive numbers such as 3n-m> 0 and the ratio
