Abstract: Paper, board and cardboard are produced by a process in which a paper stock is drained in the presence of condensates of basic amino acids with sheet formation. In particular, homo- and cocondensates of lysine and the crosslinked condensates obtainable therefrom by reaction with crosslinking agents are used in amounts of from 0.01 to 5% by weight, based on dry paper stock, as a means of increasing the dry and wet strength and the absorptivity of paper, for fixing anionic dyes and interfering substances in the paper, for increasing the drainage rate and the retention as well as the efficiency of synthetic anionic and cationic retention aids in the production of paper, board and cardboard by draining a paper stock with sheet formation.

Abstract: The invention relates to a process for producing paper and cardboard by dehydration of pulps, forming sheets and drying said sheets. Polyethylene imines of a molar mass Mw of greater than 500 000 or polymers containing vinyl amine units and having a molar mass of 5000 to 3 million are added to the pulps and subsequently, polymers containing cationic polyacrylic amides or vinyl amine units are added to said pulps, the molar masses Mw of the polymers being at least 4 million in each case. The pulp is then subjected to at least one shearing stage and flocculates by addition of bentonite, colloidal silicic acid or clay.

Abstract: Process for mixing pulverulent substances with liquids by means of an apparatus composed of a cylindrical body, the pulverulent substances being passed through the body through an axial borehole and the liquids being passed through the body in parallel thereto through a duct having an annular cross-section and the pulverulent substances being mixed with the liquids within the body in a subsequent shared mixing section, air being passed to the shared mixing section in a further duct having an annular cross-section, coaxially arranged between the borehole and the first duct.

Abstract: The invention relates to a method of producing paper, paperboard and cardboa rd by dewatering a paper material in the presence of condensation products of basic amino acids and sheet forming. The inventive method especially uses ho mo- and co-condensation products of lysine and the cross-linked condensation products obtained therefrom by reaction with cross-linking agents in an amou nt of from 0.01 to 5 wt.- % based on the dry paper material to increase the dry and wet strength and the absorbency of paper. These materials are also used to fixate anionic dyes and interfering substances in the paper, to increase the dewatering rate and the retention and the efficacy of synthetic anionic and cationic retention agents in the production of paper, paperboard and cardboa rd by dewatering the paper material and sheet forming.
