摘要： 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.

摘要： A process for the preparation of water-soluble polymeric crosslinking agents by a two-stage reaction of di-secondary diamines with epichlorohydrin and/or dichlorohydrin, wherein, in the first stage, di-secondary diamines are condensed with epichlorohydrin and/or dichlorohydrin in a molar ratio of from 1:0.5 to 1:1 at a pH of from 9 to 12, and in the second stage the condensates obtained in the first stage are reacted with additional epichlorohydrin and/or dichlorohydrin at a pH of from 4 to 8.5. The water-soluble condensates thus obtained are crosslinking agents for polyamines, polyamidoamines, ethyleneimine-modified polyamidoamines and polyether-amines. The crosslinking reaction gives water-soluble condensates, which possess a high cation activity and may be used as retention aids, drainage aids and flocculants in the manufacture of paper.
